Crispy cookies are really delicious. I ate for a month and lost nine and a half pounds. It is a high nutritional and fat-free ingredient. To put it bluntly, it can supplement the nutrients that people normally consume every day, but it does not include fat, so that the energy consumed every day is the fat stored in the body on weekdays, thus playing a role in losing weight. Because it consumes the fat accumulated over the years. So it won't rebound.
