Weight loss coffee sold by WeChat merchants is not real. Some weight loss coffee added caffeine and some herbal ingredients, claiming to help lose weight, improve metabolism and enhance satiety, but these ingredients are not natural and have not been scientifically verified. Moreover, the prices of these weight loss coffee products are usually high and lack of scientific basis, which does not rule out the quality problems of some products. Therefore, when buying weight loss coffee, you must choose the formal channels to buy, and check the product composition and production date and other related information. In addition, some weight loss coffee have side effects even if their propaganda is true, so we should not blindly believe their effects.
