Some people may not realize that dieting is an arduous battle, and it is often ineffective for a long time. Even people who lose weight successfully tend to regain their weight in the next few years. This is because not only some people are born with a tendency to gain weight, but also their bodies react to losing weight so quickly that it is more difficult to lose weight.
For those who never try to lose weight, the situation is a little different. When they eat, they don't get the same dopamine, unlike those who are addicted to fast food. When they feel satisfied, they are more likely to stop and resist excessive junk food.

Studies show that when people lose weight, their bodies will experience metabolic and hormonal changes. For example, insufficient calories will actually make the brain pay more attention to food, thus increasing the risk of overeating. Food can also trigger greater dopamine release and give more rewards.

Among dieters, the levels of casein and leptin (hunger hormones) are lower than expected, while hunger hormones are higher. "What we see here is a coordinated defense mechanism composed of multiple components, all of which are aimed at making us gain weight." Joseph Proietto, Ph.D., University of Melbourne, said.

If you are struggling, don't give up, and don't give up because the weight loss effect is not obvious. It's really hard.

None of this means that it is impossible to lose weight successfully for a long time, nor does it mean that working hard for health is a waste of energy. But the next time you criticize an obese person for not working hard, remember that losing weight is not always that simple.
