A healthy way to lose weight is exercise, which consumes enough calories to achieve the effect of losing weight. Caffeine in coffee is similar to stimulant, but its effect is weak. Drink a cup before exercise, you won't feel tired and energetic during exercise, and you can also increase perspiration and burn calories.
Because you sweat a lot, you must remember to take a bath after exercise, otherwise it will not only smell bad but also turn black!
