> The laws of thermodynamics define a group of physical quantities, such as temperature, energy, and entropy, that characterize thermodynamic systems in thermodynamic equilibrium.
If you eat 2000 calories of food and burn 2000 calories (taking into account inefficiencies in the metabolic processes our bodies undertake to convert molecules to other molecules), there is no source of energy for you to accumulate fat, regardless of anything else.
Your metabolic rate and the chemical energy of your excrement and the amount of co2 you exhale can be affected by a myriad of factors, hormonal included. But they just change the CO part of the equation, not the fact that CICO is law.
- klyrs 4y agoProblem being that calories aren't all made the same. Proteins takes more work to release their energy. Roughage like flax seed passes straight through. Even the amount you chew your food can move the needle. So, sure, if you're eating purely junk food like the sibling commenter mentions, you're probably hitting pretty close to the CICO limit. But caloric restriction is really hard to accomplish for some people, myself included, because it's physically painful. And then you look at something like how many miles you need to ride a bike just to match your basal metabolic rate, and people just give up. The CICO mantra is completely unhelpful. It doesn't capture the whole picture, and it sends people on a spiral to failure.
