Recently, more than 20 nutritionists from the United States, Canada, Italy, and other countries conducted a careful review of over 100 research articles on obesity published worldwide. They discovered that besides diet and exercise, the two main causes, there are actually many other factors that can lead to obesity. These can be summarized into as many as 10.
1. Sleep deprivation can lead to weight gain. Due to the fast pace of life, people are constantly busy dealing with various pressing problems, and over time, sleep time is gradually and unconsciously taken away from them. Long-term sleep deprivation can affect the body's biological clock's eating cycle and also lower the level of a protein called leptin in the blood. This protein has an appetite-suppressing effect and also affects the brain's judgment of whether the body has received enough food. When a person is asleep, even if they are hungry, they will not immediately get up to eat. However, when staying up late, the stomach is more likely to feel hungry, and excess calories are consumed without realizing it. >>Eating low-calorie foods doesn't work for weight loss [Image]
2. Hormonal influence. Due to the food chain, residual hormones in food may enter the human body, affecting endocrine balance and making it easier for fat to accumulate.
3. Air conditioning. When the human body is in air conditioning, it consumes less heat.
4. Smoking. The fact that fewer people around you are smoking can also contribute to weight gain. The smell of smoke suppresses appetite for both smokers and those exposed to secondhand smoke.
5. Side effects of medication can also cause weight gain.
6. Changes in the social demographic structure. The proportion of people who start to gain weight in middle age is increasing in the total population.
7. Timing of childbirth. As the age of childbirth is delayed, babies born to older mothers generally tend to be heavier.
8. Heredity.
9. Social aesthetic preferences. Overweight people are more likely to find spouses of similar body types to form families. Children born to overweight people are also more likely to be overweight themselves. There are already many overweight people, and their offspring are increasing exponentially.
10. Evolution. According to Darwin's theory of survival of the fittest, fat people are more likely to survive than thin people. Long-term evolutionary accumulation can give fat people an advantage in the group.
Some of these claims may sound absurd, but they are ultimately the result of research.
