A cup of black coffee has only 2 calories, which is a low-calorie drink, but it doesn't mean that you can lose weight by drinking it with low calories. If the diet management of three meals is not good, drinking more black coffee will have no weight loss effect.

Black coffee contains caffeine and usually has its own diet management. Black coffee can be used as a drink to promote weight loss. Caffeine can increase beneficial fatty acids in the body, and fat can be well decomposed by muscles after being decomposed into fatty acids. Caffeine can also promote intestinal peristalsis, help the body expel excess water and toxins, and accelerate the body's circular metabolism.

Caffeine is good for losing weight, but the amount should be controlled well, not exceeding 500 mg a day. Excessive intake will increase the burden on the body, leading to insomnia and headache. Do not consume too much caffeine during menstruation, pregnant women and lactation.

Generally speaking, black coffee can promote weight loss, but you can't lose weight by coffee alone. Diet and exercise are the core methods. Using black coffee during weight loss can get twice the result with half the effort.
