At first, because I seldom did exercise before, my physical condition and energy intake could only maintain my daily life.
After exercise, the energy you consume every day can't meet your exercise needs, so you need to use the energy stored in the early stage of your body to maintain the existence of exercise, thus producing the effect of losing weight.
It's like extracting a truth from a bank, only this time the body has energy:
For example, before taking part in sports, you need to consume 1500kcal (unit calorie) every day to maintain your daily needs (such as doing housework, going up and down stairs, talking, breathing, cooking, shopping, etc.). ).
So when you exercise to lose weight, you still consume 1500kcal every day, so this energy is only enough to maintain the daily life just mentioned, but not enough to exercise now, which requires you to use the energy stored in your body earlier to exercise, thus forming weight loss. Therefore, when you start exercising, you can keep the existing diet unchanged.
After a period of time, you find that your weight has remained unchanged and has not continued to decline. The main problem at this time is that your body has adapted to your current exercise.
For example, at first, you run for 30 minutes every day. At first, your body can't accept this intensity at once. You need to launch an impact with this intensity. There is a big gap between your body and exercise intensity, and it takes a lot of effort to complete it.
However, as your physical strength goes through this kind of exercise day by day, you begin to make progress, but the intensity and method of exercise have not changed.
This narrows the gap between physical fitness and exercise intensity, getting smaller and smaller, just like you feel tired just after running.
After a period of exercise, I found that you can cope with this kind of intense running without feeling very tired.
At this time, it shows that the energy consumed by this exercise is much lower for you, because your body is improving and the effect of losing weight is much worse.
So how to solve this problem?
After exercising to lose weight for a period of time, the main reason why you don't lose weight is that your physical fitness has improved, but your exercise style and intensity have not changed.
There is your physical strength in it, but you can't change it at any time. You can only make a fuss about the form of exercise to solve this problem.
We can start from two aspects:
First, change the form of exercise (clever):
This is the best choice. Compared with the first method, its advantage is originality. For example, your previous way was running. After you get used to running, you can do it in another way, not or less, and concentrate on another form of exercise.
You can change your bike. Swimming, etc. When people are new to a new sport, your body is unfamiliar with it and it takes some time to conquer it. This conquest stage is the stage where the body can give the most energy, and you can consume more calories to lose weight.
Second, increase the intensity of exercise (efforts):
After your physical fitness grows, you should increase the intensity of exercise to keep the distance between your physical fitness and exercise unchanged.
The so-called "a rising tide lifts a boat", always within a certain distance, can not let the body adapt to the intensity of exercise, otherwise it will not be able to consume more calories and slow down the speed of weight loss.
