3. Practice intermittent fasting
Believe it or not, but if you change your eating schedule, you will boost your metabolism. You can, for instance, try and eat your meals in a short period. Spend the rest of the day fasting.
4. Eat celery
Celery takes more time to digest. It will also take more calories than this vegetable contains! A stalk of celery has approximately 6 calories, but your body will burn at least 7 calories to process the food.
