Lose-weight pub

From the most simple truth in terms of the causes of obesity is the body imbalance between energy intake and consumption of the results, that is, energy intake is greater than energy expenditure, resulting in energy in the body to store fat in the form of down, over time, body weight significantly increase in the formation of fat. Specifically, these factors are the following.

The causes of obesity, genetic factors

Genetics not only with obesity but also equally relevant to weight loss. This genetic relationship with their mothers more, if the mother’s obesity, then the possibility of her child obese might be 75%, the same if the mother’s weight, her child is also the possibility of wasting 75%.

Obese genetic background of the person or there is a tendency of people suffering from obesity, his or her metabolism more efficient. In other words, if the famine years, very few restaurants can make these people alive. Speaking from the genetic background of these people live in the famine era is more suitable, it can be said that the long-term dietary deficiencies so that these people gained access to genetic characteristics, which is the “survival of the fittest” in truth, these people have a “thrifty gene.” However, if these people rich in a short time after the food has not only been met, and the intake of calories, and yet much more than, when such a “thrifty gene threshold” however causes these people and try to store too much heat down, so These people fat more easily. China’s long history of poverty, so most Chinese people access to such a “thrifty gene”, so the past 10 years, the rapidly rising standard of living so that obesity and obesity-related diseases (such as hypertension, diabetes, coronary heart disease, etc.) a threat that people the health of important reasons.

The causes of obesity, dietary factors

Dietary factors in the pathogenesis of obesity the key factor. The root cause of obesity is intake of calories than the calories consumed in line with “disease from the mouth,” the truth. So, to eat no matter what, as long as the total calories than the body needs, they will gain weight. But why some people do not eat too many fat then? Then need to consider the diet the proportion of different varieties, consumption of too much fat ingredients can promote the growth of adipose tissue, especially saturated fatty acids. Saturated fatty acids mainly from animal fats, edible vegetable oils in general also contain high levels of saturated fatty acid, cooking in the process of “excessive heat” also has made a not much of unsaturated fatty acid oxidation became saturated fatty acids. Excessive calorie intake is always associated with excessive intake of fat-related, because the same amount of fat to carry the same amount of calories than the efficiency of the starch and protein is much higher, so “eat much” does not mean “to eat much heat. ” In short, living standards, diet improvement is an important reason for obesity.

The causes of obesity, age,

With age, the body’s metabolic rate will gradually decrease, so the same amount of exercise the same diet without fat, the age of 20 can be made to the 40-year-old will be fat. Moreover, our physical activity is also increased with age and declining.

The causes of obesity, gender,

Sex is a very important factor. Resting metabolic rate in men than women, so men require more calories to maintain their body weight. Another middle-aged women after menopause are also significantly decreased metabolic rate, so in post-menopausal women in body weight began to increase notably. And men and women, eating habits, food intake and exercise volume differences, so the gender an important factor in determining obesity.

The causes of obesity, exercise

Who exercise a large consumption of calories and more fat is not easy. However, some people stopped to do big exercise sport, may have a few hours a week or even a month of the campaign, the result is not control of the weight, but increased appetite. Therefore, regular exercise can there be good results.

The causes of obesity, weight

Weight weight weight than people who need more calories to maintain body weight. For example, the person weighing 90 kg needs of 2,500 kilocalories per day to maintain weight, intake of calories a day less than his 2500 kcal, his weight will be reduced, when his weight dropped to 80 kg, when He only needs 2000 kcal a day as many calories to maintain his weight, is still a day to 2,500 kilocalories of heat, his weight will return to 90 kg.

The causes of obesity, environmental factors

Environmental factors, mainly refers to people’s social environment, lifestyle, fashion and so on. Concubine Yang of the times “to fat for the United States” Nature decided to pursue fashion people’s lifestyles. The American way of life and even make people fat, the United States, “Coca-Cola-based” or “McDonald’s style” diet and lifestyle decisions of the United States nearly 30% of the incidence of obesity. If a meal to drink sugary drinks and eating fast food, then by the time the intake of saturated calories than regular diet is much higher. Therefore, more lifestyle, “Americanization” of the higher likelihood of obesity. Similarly, competitive society, psychological pressure, anxiety, and so on are also changing people’s way of life, but unfortunately these changes tend to make people fat.
