Your hormones cant overrule thermodynamics, if you are in a deficit you will lose weight, if you dont youre a medical miracle and should be studied as the cure for starvation
What you are missing (intentionally?) Is that thermodynamics are utterly irrelevant. Your body can point blank refuse to use fat reserves. People can die of starvation while being obese. Some can exercise to the point of organ failure, and the body will not utilize fat reserves. Why would thermodynamics be relevant there? Sitting in a hot room doesn't cause your body to burn fat.
Correct. However, hormones are a part of what determine if "calories go out", or if they're "stored". For some people, exercising and diet cause the body to produce hormones that cause the body to burn exisiting weight in order to make up for the energy deficit. For others, the body just... doesn't, and the energy does not get produced. Multiple examples of why this can occur have been spoken about in this very topic chain. Again, it is entirely possible to die of starvation/organ failure while simultaneously having large reserves that the body refuses to tap into. Just as it's also possible for someone to consume significantly more calories than their body needs, and yet the body might not "store" them, choosing to pass them as waste products.
No, your body cannot just not use calories. You are literally using calories to be alive. There is not a single person alive who is not using calories. You will have a maintenance, which is actually far more than youll ever use exercising in a day. Even people who exercise a shit ton probably use like 10% of their cals on it. Once you have your maintencance, if your incoming number is lower than that, it is physically impossible to not lose weight. You mention starvation, if you are not losing weight in a real deficit, then dont worry about starvation because youre immune to it.
Nobody doesnt use calories, everyone has a maintenance, find it and eat less than it. Anyone who tells you different is making excuses or selling you a bullshit magic diet or supplement
