Overweight parents tend to produce overweight offspring even when their baby is adopted and raised by a thin couple. And, identical twins remain remarkably close in weight until early puberty, when environmental factors exert a strong pull. Heredity seems to be particularly influential in where fat settles. It also determines the strategy your body uses to get rid of excess calories. So, heredity does have something to do with being overweight. This genetic factor partially explains why some individuals can eat an enormous amount of food and stay thin while others may eat small portions and gain weight. Hearty eaters who are lean are less efficient at using the calories in food. If you are overweight, there is a chance that your body is a more efficient food burner. You have probably inherited the ability to use food efficiently and store the excess, unused calories as fat. But, all is not lost. If you are knowledgeable about your body and your food needs and put the information into practice, you will be fine.
