The first conclusion is that aerobic training like running will make your appetite stronger, while strength training will make your appetite lower.
In other words, if you often do aerobic training, your appetite will get better and better, and your appetite will also increase. If you often do strength training, your appetite will be reduced, so that your body can better reduce fat and shape.
After the conclusion, let's talk about the reasons:
When it comes to appetite, we have to mention two hormones closely related to appetite in our body, leptin and growth hormone.
The role of leptin is to reduce your body's food intake, increase your body's energy consumption and make you lose weight, so it is called leptin.
The more leptin you secrete, the lower your appetite. When the leptin in your body decreases, your appetite will increase. Long-term aerobic training will obviously increase leptin in the body. For example, some professional marathoners or long-distance runners, their leptin levels are only about one-third of normal people. The reason is that the lower the body fat rate, the more leptin you will secrete, because after your body fat rate decreases, your body instinct is to ask you to eat more food and increase the muscle fat rate to protect your body.
After leptin, let's talk about growth hormone. Contrary to leptin, the role of growth hormone is to increase your appetite. This growth hormone is the chief culprit of our usual weight gain. From the current research, we know that long-term aerobic training will increase the growth hormone in your body, while the aerobic training mentioned above will reduce your leptin. So aerobic training will make you more appetizing, always hungry and always want to eat.
Strength training will increase your leptin level and decrease your growth hormone. The conclusion is that the more strength training, the lower the body fat rate, and the thinner the better.
