My DH comes from a family in which all but he are morbidly obese and he is "just" obese. Was normal weight as an adult until he hit 40.
He has, at 46, finally started to take charge of his weight and health. He is not doing this by dieting so far but by changing bad habits he's had for the last 5 or so years. He's lost 12 lbs. in 7 weeks.
If I had bought this book before he started changing his life I don't think he would have even tried. I am not going to show it to him as I think it would depress and demoralize him instantly.
Yes, there is a genetic component to overweight IMHO and the author makes a reasonable case for a biological cause as well. But I think cultural/environmental factors largely outweigh (pardon me) these. And we can control those.
I think a lot of people regain their lost weight not because of thier biology but because they change only their weight, not the factors that caused them to gain the weight. I believe you have to do both to sucessfully keep the weight off.

Living life simply and slowly is my goal now
