Obese people often need to lose weight in their daily lives, because obesity can cause many serious problems. The most effective way to lose weight is to control diet and exercise. It's just that everyone's diet is different, so it should be necessary to reduce some carbohydrate intake. Therefore, when everyone is hungry, we need to be clear about some problems. Should we burn fat first or protein?

First, when people feel hungry, will the human body consume protein or body fat first?

If only human fat and protein are considered, the human body will burn fat first and then consume protein.

In the whole process of starvation, carbohydrate is the first passive utilization, and carbohydrate is the first kinetic energy that will be utilized by the body among the three productive nutrients. When carbohydrates are lacking in body composition and difficult to produce, they will only start to burn fat, and then protein.

In order to improve people's memory of the nutrient consumption order of these three productive forces, carbohydrates can be defined as cash, protein as real estate and body fat as savings. When the cash is completely used up, the savings are just used, and the real estate is not used until the savings are gone.

However, if the human body is hungry, it will be very prone to ketonemia or ketonuria, because human fat needs the synergistic effect of glucose in the whole body dissolution process. When the intake of carbohydrates is cut off, human fat will dissolve into oleic acid to supply kinetic energy. In the whole metabolic process here, if the human body takes the role of protein saving, oxaloacetic acid caused by tricarboxylic acid cycle will be insufficient, and oleic acid can not be completely oxidized in the air, which will cause too many ketone bodies, which can easily cause ketone bodies and cause ketonemia or ketonuria if they accumulate in the body and cannot be oxidized immediately.

So the body is not suitable for being hungry for too long. The time of the whole process will not only consume savings (human body fat), but also damage real estate (protein).

Second, health biologists have found that,

When the exercise intensity reaches 60% of the maximum heart rate, the human body consumes more body fat than sugar (glycogen) or protein (muscle). However, if the amount of exercise is large, that is, more than 75% of the maximum heart rate, the human body will immediately use all the fat, sugar and protein of the human body as kinetic energy. In other words, the harder you practice, the more calories you burn.

If you want to lose weight without losing muscle, you can do muscle training first, and then do aerobic exercise to lose weight for about 30 minutes.

Because after doing muscle training, it will not only consume the sugar stored in the body, but also cause certain damage and tear to the muscles. When muscles are destroyed,

After losing it, it will be self-sustaining, and the muscle needs a lot of kinetic energy to repair after being destroyed. Therefore, when doing aerobic exercise to lose weight after doing energy, it will ignite a lot of human fat, and it is basically not easy to drain the muscles. And in the case of rest, it will continue to produce a lot of muscles by supplementing more ingredients rich in protein. That will have a very good practical effect of increasing muscle and reducing fat.
