Oh for fuck's sake here we go again.
Bodybuilders are usually successful at controlling bodyshape for short periods of time. It remains to be seen what happens when they don't compete any more.
Just because they retire doesn't mean they stop working out. Look at Milos or Shawn Ray. I believe Rich Gaspari is still in shape too and I'm sure there are others.
It has been shown that high motivation is responsible for people losing weight on any diet program. Fat people have lost tons of weight. Diets work short term. Then slowly the weight comes back on.
Because as soon as they reach their target weights they stop using the diet/exercising habits which helped them lose the weight in the first place. The weight comes back and they blame the diet for not working.
Now, do you think that women don't care about what they look like? Appearance is extremely important to women. They read about diets, people tell them about diets, they try diets. They lose then regain more weight. Over decades the weight can accumulate.
See above.
I suspect that dieting might affect the hunger in fat people. Hungry people tend to eat more.
DUE TO LACK OF WILLPOWER AND DISCPLINE, THE ENTIRE POINT OF THIS ENTIRE THREAD.
Obesity probably doesn't exist in primitive societies. There is just too much work to do to stay alive. In modern societies such as USA we have cars, escalators, supermarkets, etc., etc. Sure there are strategies that can be used to counter the tendency to put on fat. The USA have more gyms than anyone else and good equipment. Why then are so many Americans fat and the percentage increasing each decade? How can 1/3 of Americans be obese and another third overweight? Fat people are in the majority.
You just answered your own question but incase you didn't see it let me point it out to you. Cars, escalators, abundance of food, television etc caused people to be lazier and move less. The huge portions of food adds weight and because people have to move less, the weight accumulates instead of coming off. Why are there so many fat Americans if we have so many gyms? WE HAVE SO MANY GYMS BECAUSE SO MANY PEOPLE ARE FAT. Ever hear of Planet Fitness???
If women are continually encouraged to look 'better' then why aren't more successful? It cannot be a lack of motivation. I doubt many women want to go through life as a supersized fat woman. Fat women get lectured all the time about obesity and dieting. How come it just isn't easy to reverse obesity?
Good looks and sex sells and the smart/motivated/lucky ones use this to their advantage. Everyone knows this. No most don't want to go through life as a fatass but it's easier to cry while eating a bucket of ice cream than it is to change their eating habits etc.
