14 Reasons Causes Of Obesity - 1
Obesity, however, has many causes. The reasons for the imbalance between calorie intake and consumption vary by individual. Your age, sex, and genes, psychological makeup, and environmental factors all may contribute.
Obesity tends to run in families. This is caused both by genes and by shared diet and lifestyle habits. Having obese relatives does not guarantee that you will be obese.
Some people overeat because of depression, hopelessness, anger, boredom, and many other reasons that have nothing to do with hunger. This doesn't mean that overweight and obese people have more emotional problems than other people. It just means that their feelings influence their eating habits, causing them to overeat. In some unusual cases, obesity may be used as a defense mechanism because of the perceived social pressures related to being more physically desirable, particularly in young girls. In these cases, as with the other emotional causes, psychological intervention may be helpful.
3. Environmental Factors
The most important environmental factor is lifestyle. Your eating habits and activity level are partly learned from the people around you. Overeating and sedentary habits (inactivity) are the most important risk factors for obesity.
Men have more muscle than women, on average. Because muscle burns more calories than other types of tissue, men use more calories than women, even at rest. Thus, women are more likely than men to gain weight with the same calorie intake.
