It is acceptable to lose weight with black coffee, but black coffee is very harmful to the stomach. Don't drink too much.

Black coffee can stimulate myocardial contraction and make the heart beat faster. People with heart disease should be careful to lose weight in this way.

Coffee will also accelerate the body's calorie consumption. When the calorie consumption is accelerated, it is likely to lead to hypoglycemia. Patients with hypoglycemia should use this method with caution to lose weight.
