You surely know a few people around you who are extremely thin and eat much more than you do but never get fat. They eat all kinds of food and never add an inch to their waistline.

Well just to make you feel better it's because there are certain enzymes in our body which regulate our metabolism. When these enzymes are not present in the body, it keeps a person thin, says a study. The enzyme MGAT2 is found in the intestines and determines the fate of our food by regulating it’s metabolism. It either makes fat go straight to your waistline, or converts it into energy.

Another misconception people have in their mind is high metabolism. People with high metabolism aren’t necessarily thin. If you have a high metabolism it only leads to a bigger appetite and high calorie intake. Even the fastest metabolism hardly burns maximum of 3000 calories in a day. So high metabolism is not a reason enough and doesn’t work especially if you are eating more than what your body is burning.

Leave all these myths and concentrate on your body type and metabolism. Getting thin or slim is not difficult if you are managing your diet and exercise properly.
