Only by drinking black coffee can you lose weight healthily.

The Coffee Diet continues to be circulated on the Internet, claiming that "drinking a cup of black coffee 30 minutes before breakfast can not only suppress appetite, reduce food intake by 1 pound 4, but also increase fat burning by 5%." Drinking 300 milligrams of black coffee before exercise can increase fat burning by 107%; the caffeine in it keeps the brain awake and helps control appetite, making it an ideal drink for healthy weight loss.

Caffeine increases metabolic rate

Doctors say that caffeine in coffee can indeed increase metabolism, but excessive intake may lead to side effects such as palpitations, insomnia or aggravating stomach ulcers. Can you lose weight effectively? It is still open to question.

In the past, small-scale studies have believed that there are three main theories that black coffee can lose weight: one is appetite suppression; the second is to increase calorie burning, which stimulates thermogenesis by caffeine; and the third is diuretic effect.

Excessive fear of palpitations, insomnia and gastric ulcers

In the past, the most famous black coffee dieter in China was artist Wu Qilong, who drank 13 cups of black coffee a day. Although he lost 7 kilograms quickly, he almost died as a result.

Don't consume more than 300 milligrams of caffeine a day.

Doctor Liu Bowen pointed out that caffeine is a central nervous system stimulant, which can accelerate the heartbeat, sweat and other metabolic effects, which is also one of the main pharmacological effects of coffee to lose weight, but if it is said that caffeine can inhibit appetite, it is impossible to see the mechanism. He said that there are indeed many patients in the clinic who have tried black coffee to lose weight. Some people drink more than 10 cups of coffee a day, resulting in not only stomach ulcers, but also symptoms of insomnia and anxiety. As a result, according to the Department of Health, do not consume more than 300 milligrams of caffeine a day.

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

Liu Bourne believes that drinking black coffee to lose weight is not healthy. If you really want to use black coffee as a weight loss aid, it should not be excessive, but should also be combined with the causes of obesity. For example, slow metabolism, usually not sweating, and constipation problems, with the right amount of black coffee, in addition to boost metabolism, because caffeine can also stimulate visceral sympathetic nerves, enhance intestinal peristalsis, and sometimes promote defecation. But people who already have ulcers, insomnia or heart problems are not suitable for drinking black coffee.

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

Dr. Xiao Dunren stressed that in the past clinical research in the United States, the first place for the best weight loss drink was plain boiled water, the second place was sugar-free tea, and the third place was black coffee. It is best to drink moderate water during weight loss, unless you have the habit of drinking cola and other drinks and want to switch to black coffee, but no more than 3 cups a day.
