I have tried this method before. I can be thinner, but I will gain weight immediately after I stop. I am particularly weak, because I just eat these shoes, and I will feel dizzy.
Later, I insisted on drinking a glass of honey water on an empty stomach every morning, then eating a piece of bread, a glass of milk and an apple, then drinking more water and not eating other snacks. Then, before lunch, I squeezed juice from the fruit, then I drank a cup of rice, not too full, and then I drank a cup of juice in the afternoon. If I am hungry, I will eat a piece of bread. I didn't eat any snacks on the way. If so, I insist. There is also a glass of milk before going to bed at night, because during the weight loss period, the original nutrition is uneven. Drinking a glass of milk will not make you fat. If you do this, it will definitely have an effect. I always insist on doing this. I lost weight 10 kg after half a year.
I hope it helps you.
