> The body can store and does store both fat and protein as adipose tissue. You're still not understanding. Yes, the body can store any excess calories as adipose tissue, BUT NOT WITHOUT INSULIN. That's why eating a shit ton of fat while you're still eating carbs will make you fat, while eating a shit ton of fat when you're not eating carbs will make you lose fat instead. Normally there's a feedback loop that stops your mitochondria from using more fuel than they need, bit without insulin they become uncoupled from that feedback. They start burning fat uncontrollably, which raises your body temperature. It makes your liver start spewing ketone bodies which you piss out and even exhale. Those ketone bodies have caloric value. You're literally breathing fat away.
