This eventually contributes to healthy weight loss. Here's an electrifying truth about belly fat: it can increase over time with a dramatically slowed-down metabolism. Usually, reduced internal core temperature leads to poor metabolism. Hence, it may not be your fault if you gain weight even after following a strict exercise and diet routine.
