1800 pounds for 2 Lb per week loss. 400 calories increase per day sends you into maintenance? No it would not.I wouldn't be surprised if his basal metabolic rate estimate was wrong, on this site it tells me I need to consume 2,200 calories to lose 2lbs a week its just not right, not even close. I had my basal metabolic rate determined by my doctors during a sleep study, they measure your carbon dioxide levels and O2 levels after you have fasted for 12 hours and have slept for 8, the real figure for me anyway was that I need to consume is 1,800 a day to lose 2lbs a week, the difference is nearly 400 calories so if I had followed the recommendations of this site which is just an estimate I pretty much would have gone to maintenance mode on my weight.
Just food for thought0 -
But if he had miscalculated by this much in the other direction, his two-month ordeal would not have demonstrated any weight loss at all and he would have 'proven' that junk food prevented weight loss at an 800-calorie/day deficit. Personally, if I were a professor of nutrition and wanted to demonstrate something by such an experiment on myself over two months, I would want to have given this a little more thought.herrspoons wrote: »

Of course not. But it is really simple math. How do you account for his weight loss? 800 calorie per day deficit for two months only accounts for half of his weight loss.In the interview posted later he said:5. Are you exercising at all during this experiment?
I try to get 60-120 min/week (walking mostly, cycling, lifting). I wanted the focus to be diet, so I have tried not to do too much with exercise.
Seems he did half with diet and half with exercise or other activity. Or perhaps his calculations were off.
I don't think 120 minutes of exercise per week is going to = the extra 800 calorie burn you indicated....
I would assume his maintenance level was higher than he originally estimated so he was eating in a larger deficit...
Or he was not eating as much as he thought and his deficit was higher...
Did he weigh all his foods???
Not really. BMR and TDEE are generalised figures based on best fit modelling and assumption. Good indicators, but you would expect significant variance between similar individuals.
I wouldn't if my intention was to show that nutrient composition was largely irrelevant in weight loss.
Does his paper state methods and assumptions? Is there a paper?
I have no idea where this unblinded n=1 study was first published.0 -

I did! I don't have evidence of logging it here, because it was several years ago (before I became a vegetarian), but I low carbed for years.
During that time, I lost weight to a certain point, maintained that weight for a while, became pregnant, nursed the baby, continued eating low carb the whole time .... lost the pregnancy weight. Then, life happened. Stress happened. And my emotional eating happened. I was still eating low carb. I never cheated with carby foods... I just ate. A lot. I gained weight.
Quite a lot of it.

I don't get why it's easier to assume he lied about his exercise to that extent (that's a LOT of hard exercise, and he doesn't look like he exercises hard) rather than to assume his tracking wasn't quite on point.0

I do not assume he lied. There are a variety of ways his calculations could have been off. Still, for a professor of nutrition to be off by that much (100%) in his calculations is somewhat embarrassing; at least it would be to me.mamapeach910 wrote: »I don't get why it's easier to assume he lied about his exercise to that extent (that's a LOT of hard exercise, and he doesn't look like he exercises hard) rather than to assume his tracking wasn't quite on point.

That was me when I was at least 150 lb overweight. If you take a look at my diary that's almost exactly how I ate when I was 300+ pounds except my portions were much larger, the amount of olive oil was almost unspeakable, and 3 cups of rice was a normal portion. I have regulated my portions, replaced quite a bit of olive oil calories with fish and poultry (I ate them like once every couple of months), and truncated the rest.0 -

Go to any Crossfit gym (they tend to be big on Paleo and "Clean" eating at my local box, anyway) and ask how many people have gone on a bulk? I guarantee you you can find plenty of people gaining weight by "eating clean."0 -

The result? He lost 27lbs in 2 months and reduced his body fat percentage from 33.4% to 24.9%.
800 cal x 61 days = 48,800 calories
48,800 / 3,500 calories/pound = 13.9 lbs expected weight loss
Apparently he was exercising about 800 calories per day as well.
Refer to bold in post you quoted.
I should of said bold in my comment to OP you quoted. The OP said that he estimated his TDEE. Also never said that he changed his calorie intake as he dropped weight which is interesting. My guess is what is his LBM stats to be that far off estimated TDEE calculators?
Another variable could be water weight form glycogen depletion, water weight from reduction in sodium and waste in the bowels. It's not always a straight mathematical equation.

Someone doesn't really understand "deficit", do they ?

THIS. A misconception about people who eat in moderation is that ALL our food is junk, when the reality is the MAJORITY of our food is usually nutrient dense..................and then we eat junk to fill out left over calories.ILiftHeavyAcrylics wrote: »gaurikudav3 wrote: »Thats means i can eat junk food?
Yes, but for health and satiety I wouldn't recommend getting most of your calories from "junk" foods. I'd recommend a balanced diet with appropriate macros that is based on mostly whole foods and includes more indulgent foods in moderation.

I think it's safe to assume that he lost a bunch of water weight at first, which is what messed up the numbers.

CICO works for EVERYONE. The rate may be different, but CICO isn't dysfunctional just because someone has metabolic syndrome.emilycarr71404 wrote: »CICO isn't true if you have a metabolic syndrome.

only on MFP would this turn into a debate about his TDEE numbers being off. .
he ate less then he burned and part of that consumption was twinkies..
CICO applies to all

It means you can eat what you want and you will lose weight ...however, you should be incorporating nutrient dense foods into your intake and making sure you hit macros and micros...
Actually you should be eating mostly nutrient dense foods and incorporating treats as they fit.
If we're really talking about what's best.0 -

that is essentially what I said…
but nitpick away ….
hit micros = eating nutrient dense foods0 -

You do realize that the "3500 calories = 1 pound of fat" is a loose guesstimate at best, right? It's a rule of thumb that is based on the idea that weight loss is 100% adipose tissue (which, while ideal, isn't what happens in real life).
It's obvious that putting yourself in a calorie deficit will lead to weight loss, but it isn't so cut and dry as most people on this board tend to suggest. Even this "study" is a poor example. It's one person doing this, without a control group.
