“Misreporting energy intake and output is a common occurrence that has the potential to be mistaken for metabolic adaptation. For example, Lichtman et al. [131] used indirect calorimetry and doubly labeled water to objectively assess energy intake and output in obese subjects with a history of diet resistance, and a claimed intake of less than 1200 kcal/day. In the experimental group, no subject had a TEE more than 9.6% below the predicted values (average TEE was 2468 kcal), and no subject had a RMR more than 10.4% below predicted values. It was determined that instead of some defect in thermogenesis, subjects under-reported their intake by an average of 47% (1053 kcal/day), and over-reported physical activity by 51% (251 kcal/day). Clearly, the gap between perceived compliance and actual compliance remains a major challenge to the goal of improving body composition.”

Even among the very knowledgeable and experienced, under reporting calorie intake can and will happen. For anyone who thinks they're eating 1200 calories or even 1800 and not losing, you're probably miscalculating. Maybe you're forgetting, not measuring correctly or omitting things on purpose on the weekends, you're only cheating yourself.

I enjoy reading the discussions from, and between, body builders because you're acutely aware of the delicate balances in the human body. There are lessons there for the rest us.

are you saying chocolate is not calorie free if I forget to log it?

Nice to see these informative links. Yeah, I see some anti-dieting and weight loss activists try to scare people about metabolic adaptation (basically saying, don't diet, you're doomed to be fat your whole life), while focusing on the extreme cases that don't apply to most. Some metabolic adaptation is to be expected, and even when it's a bit more than predicted, we have to question how accurate even those numbers are.

And yeah, tracking is a skill, like anything else. People get defensive when they're questioned about the accuracy of their reported intake but it's likely they are wrong, as even dieticians get their own intake wrong, though less than the general population. When I first started recording food in a diary, I had no idea how much protein was in food and stupidly thought that the weight of chicken or beef was the same as the protein. Stupid. When I look back at my first month of tracking, I can see what a mess it was. Even now, I still make mistakes, especially with pasta. Wishful thinking.

Nothing pisses me off more than remembering the next day something I ate and forgot to record. I always, always go back and enter it. It's the little stuff. Almost forgot my banana yesterday.
