The results show that people who simply drink black coffee lose weight compared with those who don't drink if they don't cooperate with healthy diet and exercise. However, in the case of exercise, the slimming effect will be more significant.
Why can black coffee lose weight? Mainly based on the following reasons.
0 1? Extremely low heat
Black coffee is a low-calorie drink, with only 1 calorie per 100 ml of black coffee.
You know, even cucumbers that are essential for weight loss have 15 calories/100g.
02? Detumescence and diuresis
Black coffee has the effects of detumescence, diuresis and intestinal peristalsis.
A cup of black coffee in the morning can not only eliminate edema, but also eliminate excess water. The weight may not change, but at least it doesn't look swollen.
03? Accelerate metabolism and promote fat decomposition.
Caffeine in black coffee can accelerate metabolism and consume fat stored in the body.
At the same time, caffeine can also inhibit your excessive appetite and break down fat, thus achieving the effect of "losing weight".
04? Increase muscle endurance and double the exercise effect.
According to the report of the World Coffee Science Conference, caffeine will be quickly absorbed by the human body after intake, thus promoting the release of free fatty acids in fat and muscle.
At the same time, caffeine can stimulate the nervous system, enhance muscle endurance, increase your exercise time, and naturally improve the fat-reducing effect.
In addition, coffee can relieve muscle aches and reduce the risk of cardiovascular diseases.
Researchers at the University of Georgia in the United States have tested nine girls who occasionally drink coffee and don't exercise regularly, and found that consuming about 2 cups of caffeine can reduce muscle soreness by 48%.
At the same time, people who drink 3~5 cups of coffee every day have a lower risk of cardiovascular disease than those who don't drink coffee 10%~ 15%.
Precautions for drinking coffee
1, don't add sugar when drinking coffee, because sugar will hinder the decomposition of fat.
2. Try to drink hot coffee. Compared with iced coffee, hot coffee can stimulate the secretion of gastric acid in the stomach and prevent fat from accumulating in the body, thus helping you consume calories in the body faster.
3. Although coffee has many benefits, it is not suitable for excessive drinking. Excessive caffeine can cause hormone imbalance, rapid heartbeat, rising blood pressure, diarrhea, constipation and so on.
Calculation formula of reasonable daily coffee intake
Refreshing: weight kg *1.5ml.
