No, the way you eat is very harmful to your health. Most importantly, when you return to a normal diet a week later, you will rebound badly.

The reason is that green vegetables can't replace the daily nutritional intake, which naturally leads to long-term malnutrition and various adverse reactions in the body.

Therefore, it is not worth the loss at all, and it also seriously damages health.
