This is like saying that a person who used to live in a place with serious environmental pollution and moved to a place with good environment would be bad for his health, joke!
The fact is that no matter how long a person smokes, carcinogens that damage blood vessels in cigarettes will not become beneficial to the body because the body is temporarily used to it.
No matter how long you smoke, quitting smoking is absolutely beneficial; No matter what happens after quitting smoking, it is a kind of redemption for the body.
During smoking, nicotine intake will reduce people's appetite. Nicotine, nicotine, morphine drugs themselves have the center to inhibit human brain hunger, so that people are less likely to feel hungry after taking these dependent items. Eating less calories in the body will make them less likely to get fat, and the reduced appetite may be suddenly released after quitting smoking, which will lead to smokers getting fat.
This phenomenon does exist. In fact, "thinness" when smoking is at the expense of blood vessels and gastric mucosa, and "fatness" is only a manifestation of the recovery of digestion and absorption function.
In addition, the way to quit smoking also has an impact. For example, if you are addicted to cigarettes, you will inevitably be relieved by "eating and eating". If you eat too much, you will get fat.
Although smokers are generally thinner, the reason is that nicotine doubles the basal metabolic rate of human body, and quitting smoking will reduce the metabolic rate to its original state. Without increasing exercise and diet, the energy consumed by the human body will be reduced, and the weight will naturally increase slightly. Nicotine can stimulate the release of reward substance (dopamine) in the brain center, and food can stimulate reward substance to a certain extent, so quitters sometimes mistake the feeling of wanting to smoke for being hungry; After quitting smoking, the blood transport in the gastrointestinal tract returned to normal, so the nutrition was absorbed well and it looked radiant after quitting smoking. Therefore, it is possible for smokers to gain 2-4 kilograms at the initial stage, but don't worry. As long as you pay attention to this problem at the initial stage of quitting smoking, you can help control your desire for cigarettes, plus a proper healthy diet and more exercise, you can be healthy and not gain weight. In addition, slimming looks good, it should be noted that smoking will hinder the delivery of nutrients in peripheral blood vessels, make people's skin aging rapidly and increase wrinkles.
Now that you have decided to give up smoking, don't look back. To some extent, getting fat after quitting smoking is a sign of getting better.
