Why does coffee help to lose weight? Caffeine is mainly working. Caffeine is a central nervous system stimulant, which stimulates the heart, nervous system and respiratory system of human body.
1, promoting metabolism and accelerating fat burning.
Caffeine can improve the blood circulation speed of human body, provide more oxygen for muscles and improve the metabolic level. Not only that, caffeine can also accelerate the decomposition of fat into fatty acids, enter the blood for energy and be consumed.
2, promote large intestine peristalsis and help defecation.
Scientific research shows that drinking coffee for a few minutes will promote the peristalsis of the human large intestine, help the human body excrete toxins and prevent constipation.
3, diuretic swelling
Coffee can not only refresh the brain, but also inhibit the absorption of renal tubules, increase the content of sodium ions and chloride ions in urine, help discharge excess water and help eliminate edema.
4. Accelerate fat burning and improve exercise effect.
Drinking a cup of sugar-free coffee before exercise is beneficial to burning fat during exercise and improving exercise effect. Because coffee can stimulate the sympathetic nerve of the human body, so that fat can be converted into free fatty acids and enter the blood, then proper exercise can promote fat to burn faster. Not only that, many studies show that coffee can reduce the body's perception of muscle pain, thus improving exercise endurance.
