> "less food" But that is true only if it is proportionally less food (that is, 15% less would mean exactly 15% less of everything). Any variation would mean that it is not 100% true: If you eat 2kg less lettuce but eat 0.5kg more fat, you're eating "less", but taking in more energy (whether you use it or not is a completely different issue ...) And if you replace your food with calorie sparse food, you can eat "more food" but take in less calories. How much calories you will actually keep or use, rather than throw out is a different question. Thus, your statement of 100% truth is wrong, and logically useless, even if practically it is mostly useful.
