Top scientists believe that weight gain is being caused by many things, there is no single enemy here. Therefore, your struggles with body fat is most likely caused by a variety of negative 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.
So without further delay, here are some theories on what’s causing your fatness:
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. Sheer number of fat cells. Your fat cells can increase in size, but they can also replicate and increase in number. Proponents of this idea believe that overweight individuals have a higher number of fat cells and therefore constantly struggle with losing weight.
3. The regulated point. According to this one, your body has a certain weight or set point that it tries very hard to stay at. Any effort on your part to change will be immediately thwarted by metabolic slow down.
4. Less calorie burning fat. The fat responsible for excess weight gain, white fat, mainly stores calories. Brown fat, however, mainly burns fat to release heat. Individuals with higher levels of body fat have less brown fat.
5. Thermic effect of food. Right after you eat, your body burns a little extra calories because of the thermic effect of food. This theory claims that lean people burn more right after eating in comparison to overweight people.
Now despite all these possible theories of fat gain, it won’t do you any good to get bogged down. Don’t think that any one theory is the end all be all to your fat loss efforts. In reality, lifestyle choices account for the majority of weight gain.
