There are two kinds of people that everyone seems to know; the one that lives a lethargic or even outright unhealthy lifestyle and still remains healthy and slim, and the one that has tried every diet eagerly and with full commitment, yet cannot lose more than just a few pounds.
These individuals seem to defy every convention of medical and nutritional science. While the general rule of thumb has always been diet and exercise will lead to weight loss, it seems that there are actually more than a few confounding factors. Discussed below are some surprising facts about how your weight works.
1 There are Genetic Factors
This one has long been suspected, and it has even used as an excuse by plenty of people who were simply too lazy to get off the couch. Yet as it turns out, there are more than a handful of genes that will predispose you to a life of being overweight. None of these are more prominent than FTO, a gene that about half of the population possesses.
Individuals with one copy of FTO tended to weight more than those who did not, and individuals with two copies of it were 40% more likely to have diabetes and 60% more likely to be obese. It is not a life sentence. Regular diet and exercise will still work, but the path will simply be a little more difficult.
2 Some People have More Fat Cells than Others
If you thought the last one was unfair, this one certainly won’t help. Some individuals actually have as many as double the fat cells of others. Perhaps even worse, once fat cells develop, they never go away even if you burn off the fat. Yet the news isn’t all that bleak. It is generally better to have many fat cells rather than a few that become overstuffed and enlarged. Proper diet and exercise will ultimately ensure that the number of fat cells you have is irrelevant.
3 You Can Actively Change your Metabolism
This one is huge! Your lifestyle actually has a prominent effect on the speed of your metabolism. A recent study by a team of Scandinavian scientists found that individuals who gained as little as ten pounds actually experienced their metabolisms slow down, thus leading to a vicious cycle of further weight gain and making the existing weight more difficult to lose. On the other hand, individuals who exercised regularly had a faster metabolism. If you refuse to exercise, try to ward off weight gain so you don’t keep gaining weight.
4 Food Can be Addictive
While brownies or cake may never have the same grasp on people as heroin or cocaine can, food can certainly be addictive. Various studies have found that when individuals are shown pictures (or even told the name) of their favorite foods, the areas of the mind linked with drug addiction responded. It is believed that dopamine is the primary culprit here, and obese individuals require more and more of their favorite foods to get the same chemical response every time.
