The maddening thing is that "eat less and exercise more" keeps coming up doesn't it? LOL! So simple and so elusive.
I, too, grew up with 3 meals and no snacking. When I was young and on my own I really ate only once a day. Not healthy, they cry, but that is what young single people do. I had no problem with my weight and I attribute that to not having a hyper focus on food in general. After kids and a lifestyle change I now am battling 25 pounds. Not much in the scale of this show, but all being relative it is frustrating.
This is where my theory enters the picture. I think by not eating properly, genetics and lack of exercise we have created a situation in our bodies that skew the hunger signals to our brain. This is what I think researchers will find. Now the fix for this is most likely life style changes for most of us and medication for the morbidly obese. So nothing has changed really other than trying to find emotional reasons which is not everyone's problem. And they may come up with other things to do to correct the problem, as well.The numbers I have always heard were 80% nutrition, 10% genetics and 10% exercise.
