[quote=Anonymous][quote=Anonymous]Ugh, formatting! Let me try again.

“Calories in calories out” IS true but HOW your body uses calories is quite individual. That is, your particular levels of ghrelin, leptin, body fat, and the sensitivity of your insulin response is unique, shaped by both genetics and your lifetime history of eating (and sleeping). This is why one person can feel full after a slice of pizza and another needs four to feel full — and why one person will lose weight on 1600 calories but someone else will need to drop to 1400.

I think this is what people mean when they say CICO doesn’t explain things. It’s also the reason why some people (but certainly not all!) find it so much easier to lose weight on a low carb diet, especially if they have naturally lower levels of ghrelin and borderline high blood sugar.[/quote]

I agree. I was listening to a guy on NPR who wrote an article for The Economist on calories (could never read it, behind a paywall) and he described how the number of calories in pasta plummets if you refrigerate it and then reheat it. The chemical structure changes with the cold, and the body is less able to extract the calories in the starch after it has been cooked/chilled/warmed again. Some bodies also extract all the calories they can from a food, and other bodies will essentially flush them, or use food energy (calories) to heat the body or do unconscious movements, where another body will store the extra energy as fat. That is all controlled by hormones, as you describe PP. So sure, the food energy you take in determines how much your body has to work with, and if it falls below some level of course it will have no choice but to use fat for fuel instead of food. But it isn't some nice, neat one-for-one calculation where if you eat 100 more calories a day you'll gain a pound over a month, or if you eat 100 fewer calories a day you'll lose a pound over a month. When people talk about it not being just calories in and calories out, what they also mean is those hormones that determine whether you store energy as fat or use it up are also influenced by what you eat, and when you eat it. Sugar and constant eating spike insulin, insulin drives fat storage. Etc. Its complicated.[/quote]
