Can raw coffee be slimming? Doctor: Drinking the wrong coffee may make you fatter

It is widely rumored on the Internet that coffee helps to lose weight, and some people pour black coffee every day, so that some people drink palpitations and shaking hands, but do not see much effect. Some people even lose weight every day, but lose more and more weight. What's the problem? In fact, a foreign study shows that coffee may really have the effect of losing weight. in this study, 16 overweight subjects, without changing their diet, combined with exercise and using raw coffee bean powder, lost an average of more than 7.5 kilograms of weight.

The researchers speculate that the active ingredient may be chlorogenic acid (chlorogenic acid,CA), which exists in raw coffee beans. Once the coffee is roasted at high temperature, most of the chlorogenic acid has disappeared. As a result, pouring black coffee may not be able to achieve the weight loss goal.

The study, conducted by Dr Joe Vinson of Scranton University and his team, involved 16 subjects aged between 22 and 46. The subjects consumed an average of about 2400 calories a day while using raw coffee bean powder to lose weight, while the exercise section consumed about 400 calories a day. During this period, the use of raw coffee bean powder was stopped for a period of time as a control.

The researchers speculate that this is because raw coffee beans contain chlorogenic acid, which inhibits glucose absorption, thus helping to lose weight. But after the coffee beans are roasted, chlorogenic acid is broken down.

Although some manufacturers have successively launched coffee products with chlorogenic acid or raw coffee bean powder, Hong Jiande, director of the metabolism department at Taipei's Shutian Clinic, points out that whether it is raw coffee or roasted coffee, there are a lot of ingredients in the coffee. everyone reacts differently to these ingredients. For example, many people in his clinic drink coffee, and as a result, their appetite increases greatly, and they lose more and more weight, while others can't sleep after drinking coffee, eat more midnight snacks, and lose weight.

In addition, people who claim that coffee can lose weight think that coffee helps sympathetic nerve transmission and may increase metabolism, but it is not appropriate to lose weight. In the past, he had found young women who drank more than three cups of coffee a day, resulting in symptoms such as palpitations, hand tremors, insomnia and "hyperthyroidism." after examination, he found that they only consumed too much caffeine.

He said that in addition to similar uncomfortable symptoms, heavy drinking of coffee may also lead to weight loss due to high levels of caffeine.

Lin Chia-ching, director of the nutrition department of the Changhua Christian hospital system, is one of the few hospitals in Taiwan to buy their own follicular coffee bags. Lin Chia-ching, director of the nutrition department of the hospital, points out that at that time, there were more men than women in Taiwan, which was related to the fact that men liked to drink sugary drinks in hand cups. It is also a hobby beverage. Black coffee is not only low in calories, but also caffeine can improve metabolism. Coffee aroma can stabilize mood and help weight control, so it is used as a coffee bag without adding raw coffee, but it is only used as a substitute for the original drink. Excessive consumption is not recommended.

In addition, chlorogenic acid is a phenolic substance that exists not only in raw coffee beans, but also in fruits and vegetables, such as apples, pears, and berries. as long as these fruits and vegetables are properly matched in a calorie-controlled diet, it is not necessary to swallow coffee beans raw.
