If you say that you have great perseverance to resist the temptation of delicious food, you can eat very little all your life, but malnutrition will cause problems.
Exercise is the best way to lose weight, but it must not be fast. You're worried about gaining muscle. Don't worry, muscles don't grow that easily. Worried about gaining muscle, you must be a girl. Are you a strength type or an endurance type? If your strength and explosiveness are strong, but your endurance is relatively insufficient, then you belong to a constitution with many white muscles. You can do some very mild aerobic exercise, such as shopping, walking, yoga, modern dance and so on. If you are a type with strong endurance and insufficient explosive force, and belong to red muscle constitution, just exercise casually, even if you eat protein powder every day, you won't grow much muscle.
Another thing to note is that if you have hyperandrogenism, you will grow muscles more easily. Just go to the hospital to be a hormone six, but even if the androgen is high, girls will not be as tall as boys.
In fact, it is very popular for girls to practice vest line on their stomachs, which is very sexy. Moreover, if the muscle content in the body is high, the basal metabolic rate will be high, so even if you eat more or sleep more, it is easier to lose weight. So girls should not blindly reject muscles. You have to be talented if you want to practice female Chinese paper. Appropriately increasing muscle content will only make you sexier and healthier, which is more conducive to lasting weight loss.
According to my years of experience in losing weight, it is not reliable to lose weight quickly. The faster you lose weight, the faster you play. Don't take any chances. If you think you have seen a living example, such as a friend who lost weight quickly and never recovered, either you didn't observe it long enough, or she said that she lost weight through exercise and dieting, but in fact she had liposuction, or she was thin and just gained weight for a short time for various reasons, such as pregnancy. The same is true for fast weight gain and fast weight loss.
The most orthodox way to lose weight is to exercise and a reasonable diet, not to eat less, but to have a moderate and balanced nutrition. And be sure to pay attention to the time of eating. This not only means that dinner can't be too late, but also means that breakfast and lunch must be on time. Skipping breakfast will reduce the basal metabolic rate of the day, and eating lunch too late will easily lead to obesity.
Losing a pound a week is the least harmful, because losing more than a pound a week contains not only fat, but also muscle and water, which is not good for your health. As mentioned earlier, if the muscle proportion is reduced, it is easy to rebound.
Losing weight is a protracted war, and rushing for success will only hurt your health. After several sudden weight ups and downs, your skin will relax and age easily. So I'd rather slow down than rebound.
Finally, I wish you success.
