Losing weight means reducing fat, not water. It is right to have less energy, but it should be matched scientifically. Fruit also contains a lot of sugar. You must find a reliable menu with dishes, and never eat it yourself.
The light of sports is not enough on the APP. Losing weight requires a lot of aerobic exercise to reduce fat, and the APP is full of anaerobic exercise. This will only be effective after anaerobic exercise. Look at weightlifters and marathoners. This is your figure. Besides, weightlifting needs a lot of oxygen.
To lose fat, you must exercise, and exercise needs energy. Therefore, to lose weight, it is necessary to scientifically match meals and strictly calculate intake. Only those who don't harm the body are healthy.
