Why wouldn’t it work in the first place? It works for sure. But people who have taken this plan should work hard and do exercises and follow the diet plans as described in the book. You might find it hard in the first few days, but eventually, you will cope up. Make sure to say one thing to yourself whenever you feel like giving up this plan. “I chose this for removing excess weight, and I’m not backing up.” It will help you in not stopping the process in between.
