>The cico balance for someone with 20% body fat is very different than cico for someone with 10% body fat. All else equal the BMR is equal. BMR is what your body would burn if you were to be in bed ALL day doing LITERALLY NOTHING. The issue you'll likely find is that BMR calculators don't equate by way of the body's proportion of fat or muscle. Muscle take calories to exist, simply to exist - even not using them, whereas fat doesn't. Someone who has 50 pounds of muscle will have the same BMR as that identical person who weighs 200 more pounds but who also has 50 pounds of muscle. What you're thinking of TDEE which incorporates daily activities into the estimation - thus Total Daily Energy Expenditure. CICO is a fundamental rule. There is nothing confusing about it. Nothing. You eat 500 more calories than you burn per day and you WILL gain 1 pound of adipose tissue in 7 days. That isn't up for debate. >metabolism Sigh. Metabolism is created by way of one's own choice. By way of what one does. Fatties don't just have garbage metabolisms by way of unluck. Fatties have garbage metabolisms by way of being lazy hamplanets, by way of living inactive lifestyles.
