CICO and fat gain

Just thought I'd through out an idea about the whole calories in vs calories out which would say that if I ate 3,500 calories over maintenance I should theoretically gain 1lb of fat that day.

So if I were to eat 10,000 calroies a day, with a caloric maintenance of about 2800-3200 depending on activity level, I should gain 2lbs of fat a day.

Just wanted to see what people that about this and if people believe this to be true? I don't believe the body would be able to consistently put on 2 pounds a day for let's say 2 weeks. That would put me up 28lbs of FAT in two weeks? I find that hard to believe.

Thoughts?

    I once gained 40+ pounds over six weeks. It's a lot easier to eat at maintenance + 3500 than at maintenance + 7000.

    Some poop floats and some poop sinks. Why might that be? I hypothesize that the floaters have a higher fat content, such that the fat survived every effort at the body to absorb it and escaped. Since absorbing the macros and nutrients in food takes actual time, it is entirely possible that extremely high calorie eating could speed the pile through the system so fast as to prevent complete digestion of all nutrients.

    Bodies aren't 100% efficient. If you eat far over your maintenance calories, your body will utilize some amount less than 100% and the rest will be excreted.

    Not at all. Your body isn't 100% efficient, and (for me) efficiency decreases with food volume.

    If I ate 10,000 calories in a day, a significant percentage of those calories would wind up in the toilet the next day, undigested. I guess I might be able to slowly increase my calories so my body got used to dealing with the massive intake, but by the time I got to 10,000 I'd be a fata$$.

    Haha definetly agree that 10,000 calories for more than a day or two would be incredibly difficult to maintain.

    I suppose the leaner you are and further from your set point the easier it may be to gain some fat. But at the same time it would seem that at some point though your body just can't process the nutrients quick enough though....

    (Mostly discusses weight loss, but he also addresses gain tangentially.)

    It's not that simple. A couple reasons for starters: TEF would go up significantly and the energy balance equation within the body isn't static.


    [ETA:] Another article Lyle wrote about it: http://www.bodyrecomposition.com/fat-loss/3500-calorie-rule.html/

    Yeah but the thermic effect corresponds to the amount of food you eat...

    If I was eating all protein for 3000 calories, 2,250 after considering the TEF and then at 10,000 it would be 7,500 after the TEF, still a pound and a half a day of fat, at the most dramatic example, obviously would not be eating 10,000 of protein haha imagine that though, like what's that, about 20lbs of chicken? Hahaha

    But what I'm saying is I don't think the TEF would really have an effect on the weight gain, I feel like there's got to be a limit to how quickly a given person can literally create fat.

    Another factor that comes into play when increasing calories for some individuals is increased NEAT which mitigated weight gain.

    I don't have time to look it up now, but there were studies done on prisoners and overfeeding which observed this, IIRC.

    Set point isn't a thing.

    More reason why a couple hundred calories over or under your daily goal won't matter much for the majority of people. Food absorption, poor measuring, nutrition labels being off by up to 10%, activity level never being the same on a day to day basis, sleep patterns, hormone balance, etc. are just some reasons why.

    This isn't difficult to figure out. Why don't you try it yourself and eat 10k/day for a week or two and see how fast you'll get fat.

    Haha yes, one day for sure, probably 2 back to back but not sure if I could do more than 2 in a row without feeling really terrible

    I reckon i may be able to do it at an all you can eat buffet, stay there for 4+
    hours and really smash the dessert bar. It would however not be enjoyable after the first hour, and i'd end up feeling sick after force feeding myself.

    CICO or TDEE calculations are pretty rough estimate, IMO. I have gained, lost and maintained all at the same caloric and activity level. I had health changes and food type changes and that caused the differences.

    Have you ever watched Feltham's 5000 kcal challenges? He eats 5000kcals of a higher carb diet and a lower carb diet. I believe he also does vegan. Different results from different foods. http://live.smashthefat.com/5000-calorie-carb-challenge-day-21/

    Wittrock does it with a 4000kcal diet challenge too.

    He gains less than expected.
