If the anti-hunger ability of the subjects refers to the survival ability, then only gain weight and reduce fat, eat more, lift weights, reduce unnecessary exercise and improve the body fat rate.
If the subject's anti-hunger ability means reducing hunger while keeping fit, then you can take the method of eating less and eating more meals.
Because the human body is very sensitive, if you don't eat for a long time, your brain will feel hungry to induce eating. At the same time, if you eat a lot at a meal, you will get fat easily because you consume too much energy.
To eliminate hunger, it is necessary to increase the frequency of eating and reduce the amount of food per meal. Most people have three meals in the morning, noon and evening, and the topic can be changed to five or six meals a day, while ensuring that they do not increase their food intake and avoid excessive energy intake.
In the long run, due to the high frequency of eating, the brain will get the signal that food is sufficient, thus reducing hunger and achieving the effect of hunger tolerance.
