 What I'd like to do is give you some more information that will help us design a strategy for weight management in the future. Something you may not be thinking about is how much people's genetics or their DNA can influence their body weight, perhaps much more than they realize. People's weight is affected by their behavior, but it's also greatly affected by the genes they inherit from their parents. The two work hand in hand to determine our weight. Scientists haven't figured out all of the ways that genes influence our weight, but they have discovered a few genes that are common in the population and may affect how much weight we gain. Genes can influence how our bodies work. They can influence things like metabolism and how quickly we feel full when we eat. Our genes may also influence certain behaviors, like how much we enjoy exercising, which foods we like to eat, and whether we're driven to eat when we're not hungry. And these things go on to affect the balance between how much energy we're likely to take in through food and how much energy we're likely to burn with exercise. So what do you think all of this means for you?
