Is body fat burning when you are hungry? Many dieters often lose weight based on not wanting to eat, thinking that not eating will consume body fat. Is this true? Could it be said that if you are hungry, you have lost weight? Do you burn fat when you're hungry? Let’s find out the answer to this question together.
Is body fat burning when you are hungry?
Not really.
When we are hungry, it is the function of the stomach to convert unnecessary things into glucose supply and balance human energy. This kind of hunger information will be fed back to our brains, so we feel very hungry. However, if you have been on a hunger strike to lose weight for a long time, once your body lacks energy, the first thing you consume is not your fat, but other nutrients. It first begins to dissolve muscle glycogen to generate energy, that is, it dissolves your muscles first. When muscle glycogen dissolves to a certain level, it begins to dissolve liver glycogen, and then it becomes fat.
The empty stomach is the body's way of telling you that it's time to eat. If you don't eat at this time, the body will metabolize glycemic growth hormone and dissolve the stored glycogen into the blood. At this time, there will be a risk of muscle loss. When you are hungry, your blood sugar level is just too low. If you eat less, your body will reduce your metabolism in order to protect you and store all the calories you eat. The same goes for being hungry. The human body will also send out warning signals when you are hungry. It will think that you are now in a dangerous situation, and being hungry for a long time will also consume the muscles of the human body.
It is indeed unreliable to starve and go on a hunger strike to lose weight.
When we are hungry, our body will preferentially encourage glycogen in the blood to be used as energy. As the time of starvation increases, glycogen substances disappear and blood sugar levels decrease significantly. In order to reduce hypoglycemia, the human body stops burning glycogen and begins to use protein as a source of energy. Since protein is an important component of muscle, the consumption of protein will directly cause muscle shrinkage. Until finally, when the protein is getting lower and lower, the fat rushes forward and becomes the fuel for the body's phosphate.
However, this does not mean that dieting will definitely make you lose weight, because the body will respond quickly after dieting and make the basal metabolism very slow to adapt to the reduced caloric intake of the body. In addition, dieting will also reduce your exercise function. In this way, the consumption of heat is greatly reduced, and the intake and consumption of kinetic energy achieve a new balance at a low level. Therefore, it is unreliable to lose weight only by fasting. If you don’t eat enough, how can you have the strength to lose weight? Healthy weight loss does not mean dieting to lose weight and not eating, but eating comprehensive nutrients that are healthy and not allowing the chance of fat accumulation.
