If a person's body wants to maintain normal activities, then you need to consume enough energy. Cucumber itself contains less energy, and the energy of water can be ignored. If you strictly carry out this plan, it means that you receive very little energy in a day. Normal adults need about 1500 calories in their daily activities, and then you go running for an hour, which needs about 2000 calories to consume electricity.
Exercise is the main way to lose weight, supplemented by diet control. The purpose of diet control is to make exercise really work, not diet control. If you adopt that extreme diet method, you can try not eating and drinking water for a week. See how much thinner you can be. It is absolutely possible. Some people around you do this to lose weight very quickly, but it is very risky for personal life and health. Because you may not feel anything when you are young, but as you get older, or because of the pace of work and life, you will find that your health is getting worse every day.
To lose weight, everyone has a love of beauty. Everyone wants to get a better figure, but it should be a long-term process, not a day or two, and it is impossible to eat nothing. You can keep 50%~70% of your usual energy income, but you can't just get 10% or even lower, which your body can't bear, not to mention.
