There is no clear scientific evidence to prove the influence of the energy bar taste of Beijing Tongrentang Yifushou coffee ketogenic milkshake on ketogenic diet. The main principle of ketogenic diet is to limit the intake of carbohydrates, increase the ratio of fat to protein, stimulate the body to produce ketone bodies, thus promoting fat burning, and achieving the purpose of losing weight and enhancing metabolism. At the same time, some energy bars and protein bars are widely used to supplement hunger and increase energy and nutrition. However, for ketogenic dieters, the contents of sugar and carbohydrate in energy bars and protein bars may disturb the balance of the body in ketogenic state, leading to their failure. Therefore, there is no clear evidence that ketogenic dieters need extra energy bars and protein bars. Although the energy bar taste of Beijing Tongrentang Yifushou coffee ketogenic milkshake can be used as a supplement, it is best not to use it as a basic supplement to ketogenic diet because of the basic principle of limiting carbohydrate ketogenic diet. If you need to use it, it is recommended to choose low-sugar and low-carbohydrate protein bars and energy bars under the guidance of nutritionists or doctors.
