Only by drinking black coffee can you lose weight healthily.

The Internet continues to be circulated "coffee diet", claiming that "30 minutes before breakfast, drink a cup of black coffee, not only can suppress appetite, reduce food intake by 1/4, but also increase fat burning by 5%." Drinking 300 mg of black coffee before exercise can increase fat burning by 107%. The caffeine in it can keep the brain awake and help control appetite. It is an ideal drink for healthy weight loss.

Caffeine increases metabolic rate

Doctors said that caffeine contained in coffee can indeed increase metabolism, but excessive intake may lead to palpitations, insomnia or aggravated stomach ulcers and other side effects, can it effectively reduce weight? Still debatable.

Small studies in the past have suggested that black coffee can reduce weight in three main theories: first, appetite suppression; second, increased calorie burning, through caffeine to stimulate the body's thermogenesis; third, diuretic effect.

Excessive fear of palpitations, insomnia, stomach ulcers

In the past, the most famous black coffee weight loss person in China was artist Wu Qilong. At that time, he drank 13 cups of black coffee a day. Although he lost 7 kilograms quickly, he almost died.

Do not consume more than 300 mg of caffeine a day.

Doctor Liu Bowen pointed out that caffeine is a central nervous stimulant, will speed up the heartbeat, sweat and other metabolic effects, this is also one of the main pharmacological effects of coffee weight loss, but if caffeine can suppress appetite, really do not see why its mechanism? He said that many patients in the clinic did try black coffee to lose weight. Some people drink more than 10 cups of coffee a day, resulting in not only stomach ulcers, but also insomnia and anxiety symptoms. Therefore, according to the Department of Health recommendations, do not consume more than 300 mg of caffeine a day.

Black coffee is not suitable for people with ulcers, insomnia or heart problems.

Liu Bowen believes that drinking black coffee to lose weight is not healthy, if you really want to use black coffee as a weight loss aid, in addition to not excessive, should also cooperate with obesity causes. For example, slow metabolism, usually do not sweat, and constipation problems, with the right amount of black coffee, in addition to improving metabolism, because caffeine can also stimulate visceral sympathetic nerves, improve intestinal motility, sometimes can promote defecation. However, black coffee is not suitable for people who already have ulcers, insomnia or heart problems.

Drink black coffee during weight loss, no more than 3 cups a day

Dr. Hsiao emphasizes that in past clinical studies in the United States, the best weight-loss drink was boiled water, the second was sugar-free tea, and the third was black coffee. It is best to drink water moderately during weight loss, unless you have the habit of drinking cola and want to switch to black coffee, but don't drink more than 3 cups a day.
