    The 72 Hour Carb Refeed Experiment

    Primal Fuel
    As many of you may know, I've been on a carb refeed kick lately. Come to think of it, you all are probably sick of it by now. While I truly believe that the Primal Blueprint is the ultimate guide to health and well-being, I believe that carb cycling is the most efficient path to weight loss, especially cutting down to very lean levels of body fat. I have written about carb cycling here for all to read. I'm going to now put my money where my mouth is. I'm going to post up for all to see a 4 week carb cycling experiment. I will sacrifice my body to science, and everyone will see whether this theory is the golden goose or a pile of goose shit. Here's how the game will be played.

    My heaviest workout days will be lumped together. During this lump, I will be eating high carb/lower fat/high calorie. On my low level cardio days and off days - the recovery period - I will be following the Primal Blueprint. I will try to keep my ratios around 60% fat, 25-30% protein, 10-15% carbs on those days, and I will attempt to eat lower calorie. This will give a "carb cycling" and "calorie cycling" effect.

    I have been eating high carb on my workout days for two weeks now, but I'm not seeing or "feeling" the results I want to feel. I think the problem is I'm doing a simple 24 hour refeed, packing on water weight and just when I begin to lose some of that water weight, I'm back in another refeed cycle. I'm going to do this by lumping all my refeed days together, then having a 4 day detox to shed the water weight and really see results. Plus, I have a hunch (based on people's plans I've seen in the past) that carb cycling is more effective when you lump it all together, then go several days without many carbs. This will test this theory. So, without further ado, here is my plan:

    Monday: High fat/low carb/low level cardio
    Tuesday: High fat/low carb/core workout
    Wednesday: High fat/low carb/24 hour IF/off from the gym completely
    Thursday: High fat/low carb/low level cardio
    Friday: Low fat/high carb/shoulders/arms
    Saturday: Low fat/high carb/HIIT
    Sunday: Low fat/high carb/chest/back

    - Low level cardio will consist of a 4 mile jog at a 5.0 mph pace. This will take approximately 45 minutes.
    - 24 hour IF's will be a fast from 8pm on Tuesday night til 8pm on Wednesday night. I will eat a smaller meal Wednesday night before bed, and it will be high fat/low carb.

    I'm hoping this will show everyone what a carb cycle really looks like. I feel people learn through example better than reading some boring technical article.

    I took these pictures right after the gym this evening, so this is what I'm working with:





    I weighed 138 lbs as of tonight. My guess is I'll have to get around 130 to be as lean as I'd like to be.

    The fun will begin on Friday night. Let the games begin.

    Will be watching as well, perhaps quietly participating but given my bad organizational skills and my awesome Hispanic mom I haven't been cooking anything in almost 2-3 months. Arroz con pollo all day! (bad for re-feeds though =/ .. ) Are you gonna post up meals/macros or just giving a general idea? I don't particularly care for numbers, but some do I guess.

    I'm surprised you weigh so little, aren't you like 5'7'? I'm 5'7' and 150. My lowest ever has been 143 for literally a day or two.

    I must have more muscle than you

    Sounds interesting, especially the grouping of your high carb days together. I think that would give better results than doing them spaced out throughout the week, but I don't have any real scientific proof that it would. It just seems that your insulin sensitivity would increase over the course of the 3 day carb-up, but I could be wrong.

    Off-topic: No resistance training for legs?! Where are the squats and deadlifts?

    I don't see a 72 hour refeed working tbh. But I'm ready to be amazed.
    You have exactly the same build as me btw. Except that I have slightly more of everything. That being fat, muscle and length :P.

    If you don't mind, I'll insert sort of a "shameless plug" of my progress in the past 1.5 years because I think it can be useful as similar example to your goals. (Feel free to ask to remove the links or the whole post if they're not appropriate)

    So, here I am nearly 2 years ago (September 2009):
    * Height: 6'5 (1.95 m)
    * Weight: 194 lbs (88 kg)
    * BF%: 10-12 (a guess)
    * Training: virtually none

    pic 1 pic 2 pic 3


    9 months ago (October 2010):
    * Weight: 181 lbs (82 kg)
    * BF%: 7-8 (a guess)
    * Training: virtually none




    3 months ago (March 2011):
    * Weight: 185 lbs (84 kg)
    * BF%: 6 (measured with caliper by the 7-skinfolds method)
    * Training: a single pull-up




    Today (June 2011) (unflexed/flexed):
    * Training: around 10 pull-ups, 10 pistol squats (just mentioning the hardest exercises)




    So, to recap, I do some "weird" combination of primal, IF-ing, and carb refeeds:
    * daily Intermittent Fasting: eating between 19:00-00:00
    * during the week, eating mostly chicken breasts, eggs, green/tomato salads and similar
    * fruit: almost every day; in the summer, lots of fruit...
    * every 3-4-5 days (once/twice a week): rice, (chinese) spaghetti, (shame on me) junk - pizza, ice cream, cookies.

    I'm absolutely stunned how much body fat is on our bodies. Let me put it in perspective: I've dropped 10 pounds since joining this site. My strength has not only maintained, but has increased slightly. I am still only halfway to a six pack. My guess is I'll have to drop to 133 before I'm lean enough to have full on abs. I'm betting you will have to drop around 130-135 pounds to have a six pack as well. It's astonishing how much body fat you still have, even at 12%. Remember, 12% body fat on a 138 pound man is STILL 17 pounds of fat. I'm going to have to cut 4 pounds of body fat to get under 10%. When you factor in water retention lost with all that body fat loss, you get to my magic number of 133. Make no mistake, it is HARD to lose 4 pounds of body fat when you only have 16.5 pounds of fat on your entire body.

    And yes, I'm 5'7". This would be a lot easier if I had height, haha.

    I used to do 48 hour carb refeeds, and I felt better and I think I was losing more fat than doing three 24 hour refeeds on my heaviest lifting days. It's like my body can't get into a rhythm on this cycle. I'm loving the 72 hour refeed idea and it fits into my schedule so much better. Plus, if I visit grandma on a Sunday, I may say "fuck it" and have my first bowl of pasta in 3-4 months. I'll just take an N-acetyl glucosamine beforehand to block the wheat lectins, a probiotic beforehand to counteract the gluten and the carbs are just what I'd need. White pasta is relatively low GI anyway and I've never been gluten sensitive.

    Absolutely. I do squats FIRST before every weight training exercise. I do deadlifts following squats EVERY OTHER weight training exercise. That will equate to squats 3 times a week and deadlifts cycling between twice a week and once a week.

    Lucky you. I wish I had more of a frame to work with. I have a lot of trouble putting on any mass at all on my arms or shoulders. I can only build up a chest, and even that isn't anything impressive.

    I can tell you that I felt more success on 48 hour refeeds than on these three 24 hour cycles I do now. I physically felt better, I performed better and I looked better, not to mention it was easier to schedule. Back in the days where I used to read Bodybuilding.com and all the success stories, it seemed the people that did High/high/high/low/low/low/low had more success than the people with their high carb days sporadically thrown throughout the week. I'm going to go with this, and I love the convenience of having my heaviest workout days AND eating days on Friday, Saturday and Sunday as they're the most likely days I'll go out to eat or drink alcohol. I can easily control my meals Monday thru Thursday, but for example, this Friday I have my friend's 24th birthday, so I will be starting Day 1 with alcohol.
