If you go to bed weighing so many pounds....?

Question

and you wake up about 2 pounds lighter...is that normal? How does fat leave the body?

Answer 1

You burn calories when you sleep. Based on my weight and sleeping for 8 hours, I could burn as much as 750 calories while I sleep.

As long as you are breathing, you are burning calories. That's why physical activity is so good for weight loss. . . because you are more active, so you burn more calories.
