The rising obesity epidemic is claimed to be a result of many factors-no single villain is to blame. Likewise, excess fat in your body can be the result of a wide variety of variables.
In an effort to explain excess body fat, scientists have come up with some theories. And although these theories aren’t set in stone, they may provide some insight as to why you’re gaining weight.
Thus, here are some explanations of excess weight gain:
1. Lipoprotein lipase. Dietary fat gets shoved into fat cells by lipoprotein lipase. According to this theory, those with too much body fat have too much lipoprotein lipase. And those with little body fat have less.
2. The quantity of fat cells. It’s not just size that matters here, it’s also about quantity. The more fat cells you have, the more likely you are to gain weight quickly. When do fat cells replicate the most? When you are young.
3. The point theory. Have you noticed that your body likes to hover around a certain weight? This could be explained by the set point theory which states that your body will resist change. So every time you try to lose weight your metabolism slows down.
4. More fat burning fat. Not all fat is greedy. In fact, brown fat actively seeks out body fat to be burned as heat. And this theory claims that people who are leaner have more brown fat while people who are fatter have less.
5. Reduced thermic effect. Proponents of this theory believe that overweight people get less of a thermic effect from food right after eating. They believe that over time this adds up and can lead to excess weight gain.
Now please don’t get too caught up with these multiple explanations of weight gain. After all, you do have a lot of control on how your body looks. Consistent research has shown that lifestyle factors account for a very large portion of weight gain regardless of genetics.
