How Much Protein Should You Be Eating?

RibsI get a lot of emails on a lot of subjects. “Mark, is toothpaste Primal?” “How many micrograms of wheat germ agglutinin can I safely consume each day?” “Did Grok even lift?” Usually, I manage to address them in the Monday Dear Mark posts, but sometimes a question deserves its own dedicated midweek post. Today’s question, or rather pair of questions, definitely qualifies. First is the titular question, “How much protein should I eat?” I get that one a lot, even though I’ve covered this in my books and in various blog posts. The second question is “How much protein do you eat, Mark?” Before we get to my protein intake (which has changed in recent years) let’s explore how much protein you should be eating. The answer – wait for it – depends on who (and what) you are. Your goals, your age, your activity levels, your size, and your health status all impact how much protein you need. And although individual protein requirements ultimately depend on dozens of variables that we can’t really know, there are some baseline intakes that can serve as a foundation for different groups. Let’s take a look.

The Sedentary

The RDA of 0.8 g protein/kg bodyweight or 0.36 g protein/lb bodyweight assumes you are sedentary, uninterested in gaining muscle, and free of health issues that might compromise your lean mass. If that describes you, the RDA is a good baseline from which to experiment. Just don’t go below that.

The Active

Athletes need more protein than the average person, but perhaps not as much as most fitness enthusiasts think (or consume). A 2011 paper on optimal protein intakes for athletes concluded that 1.8 g protein/kg bodyweight (or 0.8 g protein/lb bodyweight) maximizes muscle protein synthesis (while higher amounts are good for dieting athletes interested in preserving lean mass), whereas another settled on “a diet with 12-15% of its energy as protein,” assuming “total energy intake is sufficient to cover the high expenditures caused by daily training” (which could be quite high). One study even found benefit in 2-3 g protein/kg bodyweight (0.9-1.4 g protein/lb bodyweight) for athletes, a significant increase over standard recommendations. That said, I wouldn’t be too quick to discount anecdotal evidence or “iron lore.” A significant-enough portion of the strength training community swears by 1-2 g protein/lb bodyweight that it couldn’t hurt to try if lower amounts aren’t working for you.

The Dieters

Weight loss involves a caloric deficit (whether arrived at spontaneously or consciously). Unfortunately, caloric deficits rarely discriminate between lean mass and body fat, while most people are interested in losing fat, not muscle/bone/tendon/sinew/organ. Numerous studies show that increasing your protein intake during weight loss will partially offset the lean mass loss that tends to occur. In obese and pre-obese women, a 750 calorie diet with 30% of calories from protein (about 56 grams) preserved more lean mass during weight loss than an 18% protein diet. Another study in women showed that a 1.6 g protein/kg bodyweight (or 0.7 g protein/lb bodyweight) diet led to more weight loss, more fat loss, and less lean mass loss than a 0.8 g protein/kg bodyweight diet. Among dieting athletes, 2.3 g protein/kg bodyweight (or a little over 1 g protein/lb bodyweight) was far superior to 1.0 g protein/kg bodyweight in preserving lean mass. And, although specific protein intake recommendations were not stated, a recent meta-analysis concluded that high-protein weight loss diets help preserve lean mass.

The Injured

Healing wounds increases protein requirements. After all, you’re literally rebuilding lost or damaged tissue, the very definition of an anabolic state. One review recommends around 1.5 g protein/kg bodyweight or close to 0.7 g protein/lb bodyweight for injured patients.

The Elderly

The protein RDA may not suffice for older people, who lose thigh muscle mass and exhibit lower urinary nitrogen excretion when given the standard 0.8 g protein/kg bodyweight. What’s good for the goose may not be good for the elderly, frail gander. More recent studies indicate that a baseline intake of 1.0-1.3 g protein/kg bodyweight or 0.5-0.6 g protein/lb bodyweight is more suitable for the healthy and frail elderly to ensure nitrogen balance. As always, active seniors will probably do better with slightly more, and evidence suggests that increasing protein can both improve physical performance without necessarily increasing muscle mass and increase muscle mass when paired with extended resistance training in the elderly.

These are just starting points, mind you. Guidelines. Play around with your protein intake.

I also get a lot of people asking me about my protein intake, and apparently some people have the idea that I’m eating entire racks of ribs for meals. Actually, though, I’ve slightly modified my protein intake over the past couple years. Or, rather, it’s more accurate to say that my protein habits have changed. It wasn’t really a conscious effort; it was a gradual shift that simply happened, spurred by my body’s own appetites. You might even say it was a Primal shift. So, what’s changed about how I eat protein?

I’m eating less meat. The urge to eat large steaks on a regular basis has simply diminished. I still might have meat at most meals, but I’m having 4-6 ounces at a sitting instead of 8-12. This wasn’t a conscious decision. The craving simply isn’t there, and I’m merely eating to appetite.

My protein intake is more cyclical, than regular. Some days, I’ll finish the entire steak and be ready for more. Other days (maybe most), I’ll have a few bites and save the rest for later.

I’m eating fattier, more gelatinous cuts, like short ribs, oxtails, and shanks and making bone broth more often. I’ve always enjoyed my animal fat, so that hasn’t changed, but the gelatinous focus is definitely newer. It may have been the Masterjohn “bones and skin” post from a few years back that got me thinking more about gelatin and spurred me to be more regular with the stock-making. After all, a cow isn’t just sirloin tips and ground beef. It’s bones and skin and organs and joints, too. A 1000 pound cow will provide about 430 pounds of “retail cuts” (PDF) – steaks, roasts, things like that. Some of the leftover is water weight, but the majority of the remaining 570 pounds is gelatin, offal, bones, skin, and other “waste products” that our ancestors certainly utilized. It’s only very recently – and in select places (ahem, United States) – that people began thinking of food animals as “meat” and nothing else. Demi-glace, consomme, pho, Jamaican oxtail stew anyone?

The end result is that while I’ve reduced my “meat” intake, I’m still eating a good amount of protein. It’s just that some of it is coming from broth and gelatin now, which have the effect of “protein sparing.” In other words, eating gelatin reduces the amount of meat required to maintain muscle mass and perform all my regular protein-related physiological functions. Adding more stock and gelatin-rich meats, particularly at dinner, has also seemed to improve my sleep. Eating the whole animal makes everything easier – who knew?

Anyway, I’m eating a bit less meat nowadays and a few more plants and odder animal bits, which may be a huge shock to some of you. You know why? My needs have probably changed and my body is responding accordingly.

I want to reiterate: this was not a conscious decision borne of theorizing. My “decision” to eat less meat has only happened because I crave it less. As to why my cravings might have diminished, I have a few ideas:

I’m no longer catabolizing my lean mass through excessive endurance training, nor am I actively recovering from it. Endurance athletics (and really, any activity, but especially catabolic training like marathons and triathlons) increases the need for protein. You’d better heed that need unless you like losing muscle and bone. Since I’m not doing Chronic Cardio anymore, I don’t need to eat so much to preserve my muscle.

I’m maintaining, rather than seeking to build more lean mass. There was a short stint of deliberate mass building several years ago where I overate (especially protein) and managed to get up to the high 170s, but I didn’t enjoy it and maintaining that kind of lean mass was tough and required too much food. I’m happy where I am – both aesthetically and functionally – and so I don’t really have to eat a ton of protein to maintain.

My training is far more moderate than it ever was. I focus on play and strength training, but I mostly do bodyweight stuff (sometimes supplemented with a weight vest). This reduces the protein I need to recover and rebuild.

My “nitrogen sink” (muscle tissue) has become more efficient, allowing more variation. I don’t have any bloodwork to back this up, I just know that I’ll have 45 gram days (where I have, say, four ounces of lamb, some yogurt, maybe a bit of aged cheese and a few nuts) right alongside 160 gram days (where I indeed approach full rack of ribs territory). But those big protein days are less frequent now, and my average daily intake is right around 100 to 120 grams. I suspect this is closer to how people traditionally consumed meat – in intermittent bursts. Some days, you’d get relatively little, while other stretches were outright feasts. It definitely feels right to me.

Again, that’s what I’m doing. I think this works for me because I’m extremely clued in to my body (I’d better be after all these years!). If it tells me something – like “eat some protein!” – I trust it. If you’re not quite so far along your journey, you may not place as much trust in your body’s messaging. That’s fine. We can’t always trust our bodies at all times. In that case, start with the basic guidelines outlined above and revise upwards or downwards based on your feedback.

Losing strength/muscle during weight loss? Increase the protein.

Your favorite cut of meat suddenly disgusts you? Try reducing the protein.

Not recovering from workouts? Increase the protein.

Ideally, you should be able to bump the protein up and down depending on what your body requires. I’ve reached that point myself, and I think once you get there, it gets a lot easier. You shouldn’t have to count protein grams and I don’t want you to obsess over the numbers listed above, as they are merely guidelines to consider. As long as you’re observing the “best practices” like eating offal, incorporating gelatinous cuts and/or stock, and eating a variety of foods, your protein intake should be fairly intuitive.

Anyway, I hope this was helpful, and maybe illuminating, without being too much for you guys. Going Primal doesn’t necessarily mean gorging on meat, especially lean meat. It certainly can, from time to time, if that lines up with your goals and needs, but it doesn’t have to be that way. And as time goes on and you grow more attuned to your body, you may find yourself simply requiring – and thus craving – less meat. Or more meat, if that’s what your body needs. Bodies are funny like that.

What do you think about all this? How much protein do you eat on average? How has that changed over the years?

    • If you’ve always offerend healthy food and haven’t done too much intervening in their eating habits, you can probably trust their appetite. My (healthy sized) 5 year old sometimes eats relatively light on protein hitting mostly veggies, fruit & cheese, and then sometimes he demolishes pork chops, ribs, crab or meatballs like it’s going out of style. YMMV if your kid is heavilly invested in junk food or if you’ve been micromanaging their eating habits.

      (I won’t lie, you put crab & a hammer in front of him and he will pretty much always demolish it.)

      • Incorrect. Studies using soy protein show it doesn’t grow muscle any better than water. That is based on pee, and what is metabolically assumed to be measured regarding protein/muscle synthesis. It is a matter of balance. Yes, it is complete protein, but there is less of one or two amino acids that are the primary ones needed to grow muscle. Supplements with individual aminos care a modern way around that for non meat people.

        Dr Jason wrote on April 24th, 2013
        • Thanks, Dr. J – appreciate your science-y response. Although I know the ratios of amino acids differ in the various cuts/types of meat or other animal products, where plants fit in the whole thing still puzzles me because they each lack different amino acids. Might try not ‘counting’ the veggies I eat in my total daily protein.

          Rachel wrote on April 24th, 2013
      • Protein from plants is harder for your body to use than protein from meat. Vegetarian body builders use a lot of protein supplements (and so do non-vegetarian body builders).

        Max wrote on April 24th, 2013
      • I don’t think it was silly either. Most vegetable proteins aren’t complete, and even then, the bio-availability may be significantly less, requiring much more protein to get to a similar amount.

        Me wrote on April 24th, 2013
      • Not a silly question at all. Other nutrients vary in their bio-availability and efficacy between meat and vegetable sources, so it’s not silly to think that the same thing may be true with protein. As they say: “the only silly question is the one that isn’t asked.”

        Mantonat wrote on April 24th, 2013
      • Protein is not protein. That’s like saying fat is fat. There are different kinds of fats and there are different kinds of proteins, some are more beneficial than others.

        Legume and nut protein is mostly useless by the body. It is incomplete, and half of what is there cannot be absorbed. Egg protein is over twice as bioavailable as protein from peanuts – you’d have to eat over 100g of protein in peanuts to equal the protein quality of 50g of egg protein, and the peanuts would still be incomplete. Same thing goes for wheat protein, soy protein, rice protein…it’s mostly junk.

        If it doesn’t come from an animal source – meat, dairy or eggs – I don’t count it.

        ChocoTaco369 wrote on April 25th, 2013
        • not counting protein from a non-animal source is completely silly. your body combines amino acids from incomplete proteins quite nicely. happens all the time. vegetarians/vegans are, as a group, healthier than most. protein deficiency is largely a myth.

      • Gluten is a protein (or two)

        Since “protein is protein”:

        Eating a gluten steak must have exactly the same effect on the body as actual meat steak.

        Hmmm……..maybe it wasn’t such a silly question.

    • Not a silly question! All proteins are not created equal. Although, in this scenario, seaweed isn’t a good example of a plant source, as seaweed (and other algae) are not technically plants, so I think their proteins may differ somewhat.

      I consume around 300 grams protein per day and it is working well with my weight training/body building program. I eat 6 meals per day and shoot for 40-50 grams of protein per each meal. On my work out days, I consume around 150-200 grams of carbs and on my non-work out days I drop the carbs to around 100 grams. I’m staying lean and building muscle!

          A: Chest & Triceps
          B: Legs & Shoulder
          C: Back & Biceps.

          I rotate thru the slit Mon thru Fri and take the weekends off. My rotation looks like this:

          Week 1: A B C A B
          Week 2: C A B C A
          Week 3: B C A B C

          I perform mostly compount excercises, with a rep range of 6-12. I take all sets to near failure. I rest 30 seconds between sets and 60-90 seconds between excercises. I do not rest any longer than this between sets and excercises.

          The set rep schedule looks like this

          First Chest, Legs, or Back compound exercise is 4 sets of 6-8.
          Second Chest, Legs, or Back excercise is 3 sets of 8-10
          Third Chest, Legs, or Back excercise is 2 sets of 8-10
          Fourth Chest, Legs, or Back excercise is 2 sets of 10-12

          First Tricep, Shoulders or Bicep excerise is 3 sets of 6-8
          Second Tricep, Shoulders or Bicep excerice is 2 sets of 8-10
          Third Tricep, Shoulders or Bicep excercise is 2 sets of 10-12

          This routine takes about 30-35 minutes to complete.

    • I agree with maximus. if you are strength training and looking to gain muscle you HAVE to eat more protein, especially if you are living the low carb primal lifestyle. I cant imagine not being hungry for a big juicy steak!
      The past several months i started really getting into bodyweight strength training via the book ‘convict conditioning’ (which is an awesome book!). I just do whey protein after every heavy workout plus 3-4 eggs/day and some chicken or beef at most meals on top of heaps of veggies(and absolutely no grains/pasta/sugar as i am T1 diabetic). I have gained about 12 lbs of lean body doing this over the last few months, and never been in better shape!
      And for anyone that thinks you need to supplement heavy exercise w/ simple carbs, you dont…Im living proof! Just load up on the fat and protein! :-)

        Elena wrote on April 24th, 2013
        • Hi Elena, Ive actually never checked my ketones, only blood sugar(ive only been t1 for about 2 yrs now). I dont really understand the reasoning behind checking ketones…i know if my bs is high there will be ketones and vice versa.
          If you follow a very low carb diet you will have ketones in your blood, but this is due to ketosis rather than ketoacidosis. ketosis is when your body is burning fat for energy due to low carb consumption and is actually healthy. ketoacidosis is when your blood sugar goes high due to too little insulin and your body starts breaking down fat for energy instead, this is extremely dangerous.
          i eat about 100 carbs/day, so im probably not in ketosis, and definitely not in ketoacidosis. ……So to answer your question, no i probably dont have ketones, but they are ok for diabetics as long as they are from ketosis and not ketoacidosis.

          Shawn wrote on April 24th, 2013
        • Hi, Elena, my son (3yr) has T1 diabetes and woke up one morning with a headache. Since I myself has tried doing ketosis on purpose, I thought he might be in ketosis. Rightly so, his ketone level was 2.6 mmol/L. His blood glucose was very low as well, so we just adjusted with carbs and less insulin the next night. I don’t worry about ketoacidosis when his BG is low, but I can’t get him to drink broth when he is in healthy ketosis either (the transition to very low carb can cause a headache and can be treated with sodium, among other minerals), so I rather give him a few carbs to fend off the headache.
          Hope my answer helped you a bit.

  6. It’s nice to hear a breakdown of guidelines for specific groups of people. I’ve always just heard the 1g/lb bodyweight thrown around by different people.

    I just try to get my calories in this form:

    Although it doesn’t always work out that way, it’s a good way for me to check if I’m eating enough fat and protein. I was eating many more protein calories back when I was lifting 5 days/week, but since I’m mostly moving around at a slow pace, I’ve altered my eating habits. Plus protein can be quite heavy to carry around for a couple miles (to and from the grocery store–I don’t have a car!)…

  7. I do not know how much protein exactly I eat on average. I do know that it is a huge amount more than it used to be. I eat a portion of meat at almost every meal. At least 4 or 5 ounces, often 8 or 12 ounces. It seems to have improved everything to consume more protein than even my boyfriend does. I’m 48 and spent most of my adult life thinking meat and protein was not important. I was very wrong.

      At just turned 46 (female) I agree how much better I feel eating meat and fish again and in reasonable portions.

      Animal proteins are more complete amino acid profiles and bio-available for humans who evolved to access plant nutrition via the herbivores! I suppose it isn’t rocket science when you think about it but I didn’t want to think about it at the time!

  8. How many hours a day are you training(assuming you’re weight training) X 1 pound of steak = your protein needs.

    So if I train for 4 hours 2 2 hour sessions a day I need to find a way to eat 4 pounds of beef, along with starch, veggies and extra fat.

    Or if I only do 1 45 min session that’s only 1 pound of beef so it’s a lot easier.

  9. A classic and hugely debated topic but a refreshing primal approach which just shrugs its shoulders and says ‘Don’t stress about it!’

    I appreciate the g protein/kg body-weight guidelines but have never used them myself, preferring to allow my body to indicate to me when I’m eating too little or too much protein. Unless you’re living off scoops of whey protein, I find it a tedious to try to measure out meat portions/nuts/beans etc…

    On a side note, I ate lamb kidney last night and really quite enjoyed it. I don’t eat animal organs very often at all but figure the variety of meat is good! It’s all about flavouring your meat with quality, fresh ingredients =)

  11. I’ve always eaten protein to appetite. If I eat too much it doens’t sound appetizing, and if I eat to little I crave it. It’s the one macronutrient I know I can trust my body on. Carbs, on the other hand, are tricky for me to distinguish if I’m getting too much/little. But I don’t really know; I am far from a lean, fat-burning machine … yet!

    Emily wrote on April 24th, 2013
    • This works for me too. I lose interest in eating protein when my body has had enough. If I have meat and eggs for breakfast, I find I’m satisfied with a smaller than usual portion of protein at dinnertime. The reverse is also true. I’ve never bothered with the grams thing. I just leave it up to my body to tell my how much protein I need. Since I don’t eat sweets or grain products, I don’t worry about overeating other carbs.

        I wonder sometimes if I eat too much meat… I can out-eat some men I know with the amount of meat I can consume. I stop eating when I feel that I’ve had enough. But sometimes I could keep eating.
        It’s odd to me. No one else I know is like that.
        Is anyone here able to eat a lot of meat at one time and not feel sick?
        And is this a bad thing?

        Also, After losing 30lbs and keeping it off for a bit, I was under an intense amount of stress and developed adrenal fatigue that also triggered thyroid issues. I have since gained 25lbs (in about 10 months). :(
        I can’t figure out what to eat/not to eat (yes, I’m primal) because no matter what, I gain fat. Also I noticed that sometimes when I exercise I feel heavier as if I’m gaining fat and not muscle. WHY in the world would that happen?

  12. Great topic and well stated, Mark. I find it interesting that the focus in your article and most of the responses is meat (animal offal, gelatin) is the source of protein. Quite frankly, I think that fish, mollusks, shellfish should not be ignored and far too often is in the primal and paleo community. It is highly likely that Grok, as most of our ancestors, lived in a coastal environment and relied on sea creatures for much of his protein.

    • “It is highly likely that Grok, as most of our ancestors, lived in a coastal environment and relied on sea creatures for much of his protein.”

      Not necessarily. Grok would have gotten most of his seafood by scavenging along the shoreline. During fish runs, he could probably wade into a stream and scoop fish into a basket (while keeping a wary eye out for the local Ursus etruscus (large, ravenous paleo-bear).

      “Collagen analysis of human remains found in a cave on Favignana, an island west of Sicily, shows that settlers there 20,000 to 25,000 years ago relied on land animals—deer and boar—rather than fish, even as rising seas isolated the island. They may have lacked well-developed fishing technology.” (Samir S. Patel, Archaeology Magazine)

If the Groks got enough protein from their land animals I’m thinking they didn’t NEED to develop a fishing technology—did they recognize that fish were edible?

    • I assume an athletes’ recommendation, even if not still lifting, since you’re literally growing a whole second person from scratch. The Brewer Diet is a good reference for many. They suggest 80-100g, but I personally think they’re making this suggestion in reference to a population that tends to hover in the 50-60g range. I’ve got significantly more lean tissue than the average woman (genetically “dense”), so my personal protein requirements pre-pregnancy we’re already in that 80-100 range. Now that I’m pregnant, I definitely have noticed my increased need for protein over and above my usual, so I scale the Brewer diet recommendations up based on my body as a baseline and eat intuitively from there.

  15. I can certainly relate to intuitive eating of protein. I’m pregnant right now, which makes my protein requirements a bit higher, and I’m consistently finding that a 4 oz serving of meat isn’t nearly enough anymore. I can easily plow through a full pound of steak in a sitting, but I try to stop myself at around an 8 oz serving, just to keep my budget more manageable! I also upped my daily egg consumption from 2/day pre-pregnancy to 3+ every day now. I’d say before, I was eating 80-100g protein a day, but now I usually meet or exceed 120g.

  20. I have no idea how many grams of protein I’m getting per day, but I can tell you that I lost 20 pounds last year (my goal was 17) simply by changing my snacking habits from carb snacks to protein snacks. This was before I went primal. Simply switching from chips and pretzels to jerky and nuts made a HUGE difference for me in terms of weight loss and keeping lean muscle. I’ve been primal since the first of this year and I really do not eat any more actual meat now than I did before. My body can’t metabolize non-heme iron so I HAVE to eat a certain amount of meat to avoid anemia, but I’m not eating it at every meal and my portions at meals are reasonable. I do hit the bone broth pretty hard, though!

I’m on my 20th day of one meal a day, and the first week I was all about slabs of meat, like 9 ounces, and no veggies, just some berries. 2nd week, I began adding in some leafy greens or shredded cabbage to hold my creamy salad dressing together. Now, third week, I’m eating 3-4 ounces of protein, leafy greens every day, and some soup (if the cafeteria has gluten free.)

    It’s all from following my cravings. Which, eating Primally, are far more trustworthy than I’ve been used to.

  25. This might be me, but I’ve found if I want to lose weight quickly, I can focus on consuming large amounts of meat. It’s not something I purposely did, but found after 2 instances where I consumed over a pound of meat in one sitting with very few carbs I wake up the next day a pound or 2 lighter. Most likely this is caused by my body entering a mild ketogenic state as well as it’s usually the only meal I would eat that day due to the filling nature of protein….not sure if this would work long term or if this is just a quick boost that can be done every now and then. Anyone else have any similar experiences?

Many on this site are athletes who have no idea and no ideas about how to lose 100 pounds. You should eat more and exercise LESS until you lose enough weight that you naturally want to move more. Have you noticed how many posters do not really follow Marks advice and are still over exercising? I love this site but it can not hold a candle to Jack Kruse when it comes to weight loss or fixing medical problems. People with 100 pounds to lose, always have more hormonal issues than the athlete who just wants to loss “the last stubborn 5 pounds”.

    • Protein powder is absolutely fine. If you are on a budget, whey concentrate is an excellent choice. Whey Isolate isn’t mostly marketing hype, so you really don’t need to waste your money on it unless your budget allows you too. Stay away from soy protein.

      Maximus wrote on April 24th, 2013
  34. If I understand research right it’s also about protein quality, timing and cooking. It’s the most scarce amino acid that dictates the needed quantity and what you can build with the rest of the amino acids. If you are a frutarian and take a little extra methionine; suddenly the total protein quality skyrockets. It’s always the weekest link. Even if a meal contains all the amino acids, your DNA blueprint may think that there is still not enough of a certain amino acid and can’t start building with the rest. So; if you want to build muscle, you may need a lot less protein from muscle meat than you would if you got it from lentils and rice. I think.
    And about timing… If you eat more protein than you need for construction purposes it turns into glucose (glycogen) or fat. And that’s an unnecessary process that costs body energy and money. It would be better to eat sugar or fat if that is what your body needs. And how much protein you need for construction depends on you activity level. If you do nothing you need very little protein for reconstruction because the body’s amino acid pool is there to help the body break down and rebuild proteins it’s own proteins. But if you squat heavy 5 x 5 you may need more. So; if you weight train on Mondays and Thursdays and do nothing on the rest of the days you need a lot more protein on Monday and Thursday night than for breakfast on Wednesday (for example). Also; some research indicate that protein cycling in itself enhances the protein synthesis. Especially in the elderly.
    And last but not least. If you use heat to cook meat you not only alter the protein structure (denaturation) but there is also the generally accepted Maillard reaction to consider. It says that protein and creatin reacts with each other and turn into a new compound; severely cancerous “heterocyclica amines”, HCA’s. And my sense of logic tells me that protein and creatin can not turn into a completely new thing, but at the same time stay the same. Which would of course mean that both the creatin and protein would be useless for our bodies; since it doesn’t exist anymore. And that the new HCA’s on the other hand seem like something to avoid.
    What do you think? Am I completely out skating on thin ice?

    Fred wrote on April 24th, 2013
    • Skating on this ice I’d say. Excess total calories is what turns into fat. You can consume large amounts of protein without it turning into fat, as long as the total calorie consumption is not excessive.

      As you age your body’s sensitivity and responsiveness of muscle protein synthesis to amino acids decreases, so you need to consume more protein/amino acids as you age.

  38. Oh. And another thing. Since protein spikes insulin just as much as sugar, it’s not good to eat to much in one sitting. And it’s not about the question if the body can use the protein or not. The most common way to slow both sugar and protein down (causing less of an insulin spike) is to consume fat at the same time, but I don’t think it’s a good idea to eat extra fat just because you feel like bingeing on either sugar or protein. And in my mind; oils are just as “unpaleo” as sugar. Refined. We are not supposed to be able to eat more fat than is contained in the unprocessed food we find (e.g. yolks, offal, nuts…).
    The more I read about health and exercise, the more convinced I get that we should:
    Empty our glycogen and protein stores about twice a week with really heavy exercise.
    Then we should spend a long time refilling the glycogen stores and a short time refilling the protein stores. Protein synthesis does taper of pretty soon after exercise so it’s most beneficial to try to eat extra protein then. For construction purposes. The rest of the time should be spent slowly filling the glycogen stores via the least toxic sources of starch and sugar. And I guess that would be fruit and yams. And as you all know; consuming to much fruit in one sitting tops of liver glycogen (which means you start turning fructose into fat) and causes insulin spikes. So; in my example above; you should focus on protein (preferably meat with creatine, maybe even a supplement like BCAA) on Monday night and Tuseday morning and on Thursday night and Friday morning. The rest of the time you only need protein for reconstruction, not “new” construction. So you can eat a balanced diet of salmon, eggs, yams and fruit on the rest of the days.

I actually agree with you; I am over thinking it, but so is everyone else commenting here…

        Please enlighten me; what assumptions are false:
        1. That protein spikes insulin?
        2. That fat slows down sugar release into the blood?
        3. That oils are refined? Where do you find oils in nature but unrefined in food like fish or coconut?
        4. That the extra protein synthese induced by exercise tapers off in about 36 hours?
        5. That redundant protein (not needed for (re-)construction) is converted to glucose or fat?
        6. That large carbohydrate meals cause unhealthy insulin spikes?
        7. Or maybe (and I understand that this i blasphemy here) that eating unneeded protein from meat may be less than perfect?

    2) I’m usually way off when I try to estimate the weight of an amount of protein (e.g. what looks to me like 4 oz can be more like 7 oz).

    So, for me, it’s worth weighing.

Given the size of my particular fist, that is just under 4 oz for a serving. It’s a nice visual for me because it means that when I eat out, I can easily eyeball what’s been served and determine how much I’m going to eat at the restaurant. The result is that generally my husband and I split a meal AND take some home in a box for later. :-)

    • I find the same. I have to weight the meat and chicken i eat and for me 3-4 oz max. I’ve also had regular blood test as higher levels previously caused me to have elevated Uric acid (way out of range) and also higher than normal liver enzymes. This is despite exercising daily and doing interval training (quite intense) and usually some weights although I’ve been having a break from this lately. I also bought a scale and I even travel with it. And for the time being I log things on to see the macronutrient breakdown when I can.
