Moms Need Steak and Yet Another Fasting Study

By Mark Sisson
81 Comments

First on the docket for this round of Monday Musings: steak. Steak is an objectively good thing. It can heal wounds and improve your squat. There’s really no conceivable reason not to eat steak, and plenty of reasons to cram it down one’s gullet on a regular basis. O sacred slab, thou finest fuel for metabolic processes. Gift of cud and hoof… Okay, let me get to the point, before I get off track and turn this post into a terrible 2,000 word ode to steak.

Steak is a rich source of B-vitamins, especially B-12 (fish and dairy are also good for it), which is crucial for infant neurological development. A new study suggests prenatal B-12 levels might even influence a baby’s propensity to cry. Researchers tested the B-12 levels of 3,000 pregnant women three months into their pregnancy; after their children were born, they measured the infants’ crying patterns. Kids born to mothers with the lowest B-12 levels were more likely to cry louder and longer – up to eight times more likely than kids born to mothers with the highest levels. I don’t blame the kids. I become a weepy mess if, say, my ribeye isn’t thawed in time for dinner. Hmm, so what’s the solution? Eat some steak… right?

Wrong. The resident nutritionist warns that meat “comes with saturated fats which can hinder the body’s use of essential fats needed for the baby’s brain and nervous system development.” I guess nothing’s safe, eh? (That’s sarcasm, in case it isn’t clear.)

Next up, there’s a new review study out that’s pretty favorable to intermittent fasting. Only here they call it “intermittent calorie restriction,” which involves 24 hours of ad libitum food intake alternated with 24 hours of “complete or partial” calorie restriction, and they compare it to regular calorie restriction. Both methods seem to work well for weight loss, but intermittent fasting – er, sorry, I meant intermittent calorie restriction – preserves more lean mass, which is the stuff we want to preserve, especially as we lose weight. Otherwise you’re on your way to being skinny fat. You see that a lot on folks who consciously and painfully restrict calories, whereas the people I know who IF tend to run leaner and denser. Weight is such a vague figure when it comes to human health, anyway. I prefer to know how much three dimensional space my body’s mass is occupying, or how much water it’s displacing. The denser you get, the less space you occupy. You can have a tight, muscular body and weigh as much as or more than the classically overweight guy.

So, to sum up, this is yet another review suggesting that IF is the best way to lose fat mass and preserve lean mass. They didn’t get into which mode of calorie restriction was easier and more sustainable, but I’d wager that intermittent calorie restriction takes that title as well. It really does seem to be racking up the wins as of late, yeah?

That’s it for today. Feel free to chime in with tales of steak and IF success!

The nutritionist quoted in the meat study is a vegan. Why ask a vegan nutritionist’s opinion on a study about meat? More media shenanigans I guess. Gotta get a dissenting view.

I think the problem with many health studies is that the researchers come into the study with their own biases. This influences what they notice and how they interpret it, and the conclusions end up being plain ridiculous.

Life since IF has been a dream compared to before. I no longer feel like I’m going to die when I find myself without food for a few hours. It just takes a week or two of IF practice to get good at lasting those hours. As a benefit, when there’s less than optimal food around, I just skip eating until later.

A huge benefit to IF over pure calorie restriction is that you can gain the metabolic and restorative benefits without waisting away. I no longer want to lose weight, I just want to maintain.

The resident nutritionist warns that meat “comes with saturated fats which can hinder the body’s use of essential fats needed for the baby’s brain and nervous system development.” Do these nutritionists think before they speak? Really, they are never pressed for an explanation and they need to be. And of all the ridiculous cock and bull associated with the saturated fat boogey man, this is the first time I’ve heard anyone suggest that saturated fat consumption “blocks the absorbtion of essential fatty acids.” What fat does she think the brain and nervous system are lagely made of? Canola oil? Mothers… Read more »

I’ve been on a HUGE steak kick this week. No clue why (funny enough, my mother’s first suggestion was “Maybe you’re pregnant.” lol! Tho, definitely not the case at this time.) but I woke up the other day craving steak, the bloodier the better, and that’s just…kept going. Rather surprsing for me, since though I love meat, I rarely shell out for steak.

You’ve already got me on board. I’ve been IFing for almost a month now, I eat my food in between 12pm-8pm +/- an hour. It is nearly impossible to gain weight doing this and I continue getting leaner in a linear manner despite not being overweight to begin with. It is a harder habit to explain than Paleo itself though, people just can’t wrap their head around skipping breakfast.

Here-here! Nutritionists these days are notorious for parrotting unsupported rubbish like this all the time. Saturated fat is so demonized anymore that no one expects a dietician who is critical of saturated fat to back up their claims. It’s so universally accepted, medical and dietary journals don’t even bother to cite studies to back up claims to the dangers of saturated fat anymore. Do dieticians not realize how important their job is? Do they not realize how critical a healthy dose of skepticism is in this line of work? Do they recall anything from their intro to physiology class? It… Read more »

I actually started eating meat midway through my third pregnancy… (vegetarian up to that point) – I was CRAVING it like crazy. Turns out there was a reason for that… she turned out to be a pretty chilled baby, NEVER cried (although, I attribute that as much to our attachment practices as I do to her personality)

Steak may be good for those things, but I’ve heard that red meat can also be bad if you eat too much of it.

College Caveman (Musician)
5 years 6 months ago

You must be new here 😀

Contrary to popular belief, “too much red meat” isn’t actually bad for you.

The idea that meat is harmful was something pushed by the catholic church centuries ago to dissuade sexual intercourse.

It’s the same reason Kellogg’s invented his corn flakes — to cease masturbation (google it).

Someone correct me if I’m wrong, it’s been awhile since I’ve looked into this >.>

Hadn’t heard the bit about the Catholic church but it wouldn’t surpise me much.

You are correct about Corn Flakes–they were originally designed by Kellogg to be an anaphrodesiac. Learned that in my Human Sexuality course.

So even back then people believed grain-based cereals would impact hormones like that?

How did Special K and all the other “healthy” cereals ever become so sexy? Marketing is POWERFUL.

It’s ironic that people who are trying to live healthful lifestyles are using cereal as one of their tools to do so.

Quick Follow-Up College Caveman: I had not heard that about corn flakes, kind of odd if true. The piece on meat and the Catholic Church is not by any means the driving reason. Meat was historically regarded as a delicacy and usually reserved for feasts and celebrations by ‘lower or working classes’ (killing the fattened calf for feasts was a common practice espeically by Jews). It was seen as a mini sacrifice to ‘give it up’ something enjoyable for a short period. Fish and seafood was still allowed because many of the original apostle’s professions were as fishermen (and the… Read more »

I find myself craving steak more than anything else lately, and this is coming from someone who ended 10 years as a vegetarian and became Primal. With the IF, I don’t find that difficult to do. I go with a natural flow now. There are times during the month that I have a huge appetite and so I eat more during those days and don’t skip meals much. And then there are times like now where I don’t have much of an appetite at all, so it’s easy to skip meals and usually I’ll just have a small dinner.

A grassfed steak has (and plants don’t in any appreciable amounts, not that I dislike plants) B12, Zinc, CLA, carnosene, carnitine, creatine, K2, choline, etc etc. I love you, steak. You make my wallet fuller. And mega nutritionist nutrition knowledge fail. Even if it were so simple as LDL: Bad!, there is a lot more monounsaturated fat (including stearic acid which gets turned to oleic acid) in a steak than palmitic acid. There is also CLA which reduces bad LDL without touching HDL. All in all HDL up, LDL down. Maybe her vegan brain needs some choline, B12 and creatine!… Read more »

Ugh… fasting isn’t about “calorie restriction” per se, it’s about hormonal balance. Mixing “fasting” with “calorie restriction” confuses the issue and offers no insight.

Oddly enough, when I went vegetarian for a few years, it wasn’t red meat I craved, it was sea food.

These days I eat some red meat but it’s a bit expensive to find good, organic beef in my area (which is ironic considering I live in the SF bay area) so I usually stick with sea food and chicken. Still, the occasional burger does find itself onto my plate to be enjoyed, sans bun of course 🙂

The first thing I craved with each pregnancy was a big, thick, juicy steak. Like clockwork — before the test had come back positive. It was one of the main signs. Today both girls love steak. Then again, who doesn’t??

There was a popular sitcom, “Friends” (some of you may remember it, lol) in which one of the main characters was a practicing vegetarian (because she felt bad for animals). Once she got pregnant, she craved meat all the time, and eventually started devouring it. Makes me smile to think how even Hollywood will bend to the cravings of pregnant woman! Being pregnant takes you back to the basics of life– and what is more basic than good old red meat? Yum.

Kristina

About 6 years ago, I ate a beef burger and my stomach hurt for 2 days. I then tried a steak and the same thing happened. So, I assumed that I was like many and just didn’t have the B12/iron in my system to break down the meat. So, I just took supplements and didn’t eat beef.

After a few months of Primal (…I don’t know what else it could be), I can now eat all the steak I want! Yes please!

Juliana

I craved steak all the time when I was pregnant. It was heaven on a plate.

My daughter, Luna, is 19 months old now, and I’m still breastfeeding her … and guess what? I’m still craving steak and red meat more than anything. I’m at the point where I’m not shy to eat it once or even twice a day if need be …

I have her on a paleo diet, which seems to be going really well so far …

I would most definitely feed myself correctly instead of the way I fed them back then. I hate stupidity.

Ok so is the article saying that intermittent fasting is beneficial and the way to do it is to restrict calories for 24 hours then eat as much as you want for 24 hours and continue on like this constantly or is it just a once in a while deal? And how much do you restrict on the calorie restricting days?

Roland
5 years 6 months ago

No, this is just a study that suggests benefits of IF vs straight calorie restriction.

MDA has several good articles on IF. Many are right at the bottom of this article, under “Related Posts.”

As to how much to restrict, that’s a matter of goals. When my goal was fat loss, I would heavily restrict calories on some days (using IF as a tool), then eat somewhat normally on other days.

My family used to eat steak very rarely not because of fear of red meat but because we thought only expensive filet makes a good steak. I actually did not enjoy steak during that time. One day, my mom decided to fry up some top blade steaks (they were actually labeled as steaks) she usually she uses for stew. They were so good! Less tender, but cheaper and more flavorful than filet. Now we all eat steak much more frequently!

I found this interesting and confusing:
“Results reveal similar weight loss and fat mass loss with 3 to 12 weeks’ intermittent CR (4-8%, 11-16%, respectively) and daily CR (5-8%, 10-20%, respectively). In contrast, less fat free mass was lost in response to intermittent CR versus daily CR.”

If the weight loss and fat loss were the same, how did one group lose less fat free mass? Is it just me or does that seem impossible to others too?

Roland
5 years 6 months ago

“Results reveal similar weight loss and fat mass loss.” It does say similar, not that it was the same weight loss. There is always adding some lean tissue like muscle alongside losing fat, too. That can make weight loss much less.

Jim
Jim
5 years 6 months ago

I guess I was interpreting it to mean that the difference in fat mass loss and weight loss was not statistically significant, while the difference in fat free mass loss was significant.
The abstract doesn’t say that either, so now I kind of wonder what they numbers really say.

Christine

I’m nearly four months along in my pregnancy and I -WISH- I could eat some steak! Prior to this I’d been fairly hardcore paleo/primal for a couple years and LOVED it, but pretty much as soon as I became pregnant, the very thought of meat made me run for the toilet. Right now I can eat a tiny bit of fish and chicken from time to time, but steak is still a no go. 🙁

Christina – I am in the same boat as you! We just traveled to Argentina (where the baby happened to have been conceived) and ate steak twice a day there. Now that I am in my 8th week, I can’t even stomach the thought of any meat (the occasional chicken and seafood are okay). Its so hard to stay primal 🙁

I had three gestational diabetic pregnancies and never returned to “normal” blood sugar after the third, so do take care of yourself. That said, primal eating is a great way to minimize any of those problems and it’s how I handled the pregnancies and also how I keep my blood sugar down now. Oh, and my babies have all been lovely and peaceful, for what it’s worth. (Can’t say if it’s eating meat or getting to nurse in bed with momma that does the trick, but we don’t have cranky babies around here.)

What a timely post Mark! I have been eating a lot of beef lately (tonight’s dinner was about 12 oz. of filet mignon, spinach sauteed in pastured butter, and a couple of glasses or red wine), and it’s nice to hear that steak is Sisson-approved.

I have noticed that 12 oz of steak is more satisfying than 2 pounds of cheese pizza (possibly from Costco…), and I don’t raid the fridge later in the night.

I say “eat to satisfy”, and steak fits the bill to a T (bone).

Fasting and low carb/primal is the best way to preserve muscle. It also enhances growth hormone production. You must begin fasting slowly by eating progressively later day by day until you can go for 20 or more hours without solid food.

Advice for pregnant women really varies by country. I’m American, but I live in Slovenia, which is also where I had my second and third babies. When I showed up for my first prenatal appointment with the second, the nurse was running down her list of counseling points. When she got to food, she said, “And be sure to eat lots of horse meat because you need the extra iron!” I nearly fell off my chair because I was sure I’d misunderstood her (I didn’t speak the language well and didn’t know that horse was a common food here.)

There’s plenty of outdoor recreation available, easily accessible from any location (including the capital city): hiking, skiing, rock climbing, swimming (lakes, the Adriatic, numerous natural springs), river rafting, hang gliding, etc. I live only a 10-minute bike ride from downtown and have a huge, wooded park right out my back door (hiking trails, wild blueberries and chestnuts, cuckoos and frog ponds, etc.).
