I agree with this. As a non overweight person I don't feel hungry all the time. However, I don't think it is genetics can explain why the obesity rate has exploded in recent decades. Seeing friends and family members that are overweight, they tend to have some similar habits. They consume a lot of liquid calories, ie sodas, fruit juice, sugar in coffee etc. They also eat calorie dense foods, ie ranch dressing, fast food, cookies while consuming fewer fruits and vegetables. They also tend to not consume as much protein and are usually fairly sedentary. I don't think blaming individuals does much good, but at the same time I don't think some people are just doomed to be fat. If everyone around you is eating healthy non calorie dense food and walking a lot you probably will too. Conversely if everyone around you is eating high quantities of processed food while being sedentary you probably will too.
