Have a full lunch, or it will affect your normal life. It may also cause hypoglycemia, so you can choose to eat more vegetables. The kind with high fiber is easy to feel full and has low calories. For example, celery is very good.
You have to eat dinner, too The energy of cold noodles seems a little low. You should be hungry if you run late, right? Or run to the back and feel a sense of detachment. In fact, you can choose some foods rich in carbohydrates for dinner, such as rice+fried vegetables or potatoes.
You should be clear about the concept of weight loss, not the change of weight, nor the result, but the change of body fat rate. That is, how much body fat accounts for body weight. When you convert a large proportion of fat into muscle, your weight may change little or nothing. But you really lost weight. So no matter whether you lose weight successfully or not, don't look at your weight too much. I'll tell you a simple way to squeeze out those fats after exercising for a while. You will feel a clear sense of solidity or lose weight. That is to lose weight.
There is also a wrong view that losing weight = eating less or not eating+exercising a lot. However, it is often difficult to maintain enough exercise without adequate diet, and it is also difficult to transform body fat without adequate exercise, so weight loss should be moderate diet and exercise.
A proper diet is low in fat, sugar, calories and protein.
Moderate exercise refers to certain anaerobic exercise plus aerobic exercise.
I hope I can give you some help and wish you good health!
