Interesting facts about overweight
What is the main cause of obesity? Popular wisdom claims that it is overeating. However, recent research suggests that what matters is not the quantity but the quality of what is eaten.
An Indiana University study found that obese people consumed the same number of calories per day as thin men and women.
However, obese people derived more of their daily calories from fat. Men and thin women derived 20.7 percent and 28.6 percent of their calories from fat, compared to 33.1 percent and 36.3 percent, respectively, for obese people.
In the observation of 109 women and 107 men, the researchers found that the thinner the subject, the higher the percentage of carbohydrates consumed. Overall, lean men and women derived 52.6% and 52.9% of their calories from carbohydrates, compared with 48 and 44.3% in obese men and women.
Similarly, the researchers found that animals with a diet high in fat and/or high in sugar can become significantly overweight, without the need for them to overweight in food. In fact, animal studies suggest that if the diet is high in fat, a man would need to cut calorie intake by at least 50% just to stay thin, it should be noted that this is not being recommended. For a severe reduction in calories has its own health risks.
It is not clear why calories from fat cause greater weight gain than those from carbohydrates or protein. "It has something to do with the physiology of fat metabolism," said study author Wayne Miller.
Miller says we're more efficient at storing calories or that fat calories are better absorbed during the digestive process than other calories. Another possibility is that fat slows the pace of metabolism. Consumption of refined sugar has also been reported as a fat-producing agent.
Although research on rats under certain laboratory conditions has found a link between obesity and a diet high in sugars, it is more difficult to interpret similar research in humans. However, it may be that obesity is characterized by excessive consumption of "added" sugars, while slenderness is characterized by high consumption of "natural" sugars.
