I watched an interesting show on discovery about people in america being fat, and what different people are doing about it. They showed the different studies and theories on why people are fat now, when they weren't before and how genes does make a difference but is not an excuse. It was very interesting. Actually got hubby and I talking about it and debating.
They made a lot of good points I hadn't thought of before. Makes me think that "the caveman diet" holds a little bit of merit... and I feel like i learned a lot. I dunno. Anyway, the link doesn't tell much about it, but...

Basically what I got out of it was a few scientists explaining that since the 60's we have only increased our caloric intake by about 200-400 calories per day. Not enough of a difference. However, our activity has gone down, i don't recall what percentage but i think it was in the 30's to 40's percent.
Also, that the people who blame it on genes aren't blaming them for the right reasons, and that genes to come to play because as cavemen you had to be able to put on a lot of fat to keep you through the winter,but the activity and hard work would burn it away, along with starvation during the cold months.
So, when you are starving your body, it thinks it needs to hold on to as much fat as it can, which is why people who diet frequently gain weight or lose it then gain it right back. Body goes into survival mode.
Also that some bodies ARE predispositioned to be overweight, but that doesn't mean that you will be. Same as having alcoholism run in the family, just because it does doesn't mean YOU have to be one. You have control over it.
Anyway, it was just interesting and i thought someone might like to catch it if it's on again. Any opinions on their theories?
