Recently, it is widely rumored on the Internet that drinking lemon juice and Yakult for three meals can not only lose weight, but also beautify. However, Zhao, a nutritionist at Tai 'an Hospital, pointed out that this diet is hard to last. Zhao pointed out that the acidic substances in lemon juice can accelerate metabolism, while Yakult contains beneficial bacteria to help digestion. However, if this beverage completely replaces dinner, the calorie intake is too low, which will not only lead to side effects such as dehydration, lack of physical strength and weakened resistance, but also reduce muscle instead of fat. Moreover, the capacity of a small bottle of Yakult is 100 cc, but the heat is about 100 kcal. If you drink four or five bottles a day, you may lose weight instead of gaining weight.
