Coming from a person who is old enough to be, for most of you here, a parent. I have to say that obesity, especially with young people is becoming a serious problem. I'm not talking about, what my generation referred to as "baby fat." Ten to fifteen pounds heavier than your friends. But, Morbid Obesity. Fifty pounds or more, than what would be healthy for that person.
I think a lot of this is due to lifestyle and diet. When, I was a kid...yes I already warned everyone that I am old enough to be your mom. We played outside. We did not have X Box or the internet. Plus, most of us ate home cooked food. There was no where near, the amount of fast food that there is today. Foods were not overly processed. You ate vegetables, and lean meats, which where baked, instead of battered and deep fried, in God knows. What ever un-healthy oils they use. Type Two Diabetes and High Blood Pressure was unheard of with children. These are middle age diseases.
Sure, we ate pizza and had a coke. But, this was a treat. It was not part of our everyday diet. We drank milk and lots of water, ate an apple, and had soup for lunch. Sadly, I think my generation is going to be the first, to out live our kids.
