Metabolism really is the 3rd but missing secret to fast, painless fat loss. You already know the first two, as you see them everywhere you look:
- Eat less: Lowers your calorie intake. Less food to be stored as fat. But can be painful and hard to stick to for any period of time, due to your body being used to a certain level of calories.
- Exercise more: Burns more calories. And if you exercise on an empty stomach it can force your body to burn fat. But with an empty stomach, you have nothing to fuel your exercise, which makes it so much harder to stick to.
