[vestax]

can someone explain why? Does the rxn of ur stomach breaking the carbs down release heat? Also when you burn fat where does it go? do you sh*t it out? do you piss it out and what are the byproducts?

Fat stores are converted to blood glucose for energy, which is utilized in conjunction with the oxygen in your bloodstream for activity. Any residual byproducts from the fat metabolism (toxins etc) are removed by your liver (primarily) and your kidneys (to a lesser degree) and yes these are removed from your body via waste. Body fat stores are only mobilized when your activity level creates a calorie requirement above your calorie intake. Thats a pretty basic explanation.
