The time to lose weight by drinking magic coffee is also very particular. It is best to drink a cup of coffee within half an hour to an hour after a meal to accelerate the digestion of the gastrointestinal tract.

Drinking a cup of coffee before exercise can increase the effect of exercise, because coffee can improve the process of transforming fat into fatty acids. If obese friends want to drink coffee to lose weight, they must add some sugar and milk. If they are not used to the bitter taste of coffee, they can add a small amount of milk or a proper amount of coffee sugar, but the less the better.
