The weight loss principle of black coffee.

First:It can promote the decomposition of hidden fat

The caffeine in coffee has the effect of increasing the concentration of fatty acids in the blood. And once the concentration of fatty acids in the blood rises, the fatty acids are absorbed by the muscles and consumed in a way that converts them into energy for the body. That is to say, drinking coffee promotes the breakdown of fat that has been accumulated in the body for a long time.

The ingredient that helps to eliminate constipation is a rapid "humoral hormone" or neurotransmitter mechanism. It has been found that only 4 minutes after drinking coffee, the movement of the large intestines begins to strengthen, and this effect of stimulating gastrointestinal peristalsis is strongest in the early morning and weakest at night.
