Most normal people need about 1600-2400 kcal of energy every day. One egg (about 60g) can provide about 90kcal, and the energy of two oranges (about 400g) is about 192kcal, which is 282kcal in total, even less than a fraction of one day's energy.
If you eat like this for a long time, you can't provide enough energy at first, and your weight will naturally drop, but your muscles will also decrease; Due to the lack of carbohydrates, protein and fat, as well as a variety of vitamins and minerals, fatigue, dizziness, hair loss, endocrine disorders, dark yellow complexion, mental trance and depression, palpitation, hair loss, memory loss and other symptoms will occur. Dieting in adolescence will also affect the development of height and secondary sexual characteristics, and in severe cases, it will damage the liver, heart and kidney.
Such a long-term diet will inevitably cause physical discomfort. And once the normal diet is restored, it is easy to have retaliatory overeating. What grows back at this time is often fat, and it may be fatter than before. At this time, it is easy to produce psychological self-rejection, and the sense of guilt when eating gradually develops into anorexia.
Therefore, it is more reasonable to choose the energy intake (generally 300-500kcal lower than the normal diet) and the way to increase exercise. People who want to lose weight must learn some nutrition knowledge and learn food collocation. Don't lose weight, resulting in incomplete nutrient intake, which will affect the catabolism of fat.
Pay attention to the speed of losing weight, generally 0.5- 1kg a week is appropriate. If you don't rebound within six months after losing weight, you can say that you have lost weight successfully.
