Eating too much food all of the time can cause you to gain weight? True or False?

BYU recently came out with a fascinating study on gaining weight: The result? If you do not show restraint when eating food, you will gain weight. Yes, you read that correctly. If you do not show restraint when eating food, you will gain weight.

And if you didn't know what restraint was, they tell you: Restrained eating is choosing not to eat as much as you'd like. And then more explanation, 'You need to restrain from unhealthy foods, from high caolorie food. If you don't, you will gain weight.'

Shocking. So, now I can remember this study when I go out to eat and I order a triple cheeseburger, supersized fries with cheese all over it that I am not showing enough restraint and that I will probably gain weight. Before reading that study, I couldn't, for the life of me, figure out why I was gaining weight. Now I know.

I have also heard that there is a ground breaking study on how if you do not exercise then you will be out of shape.

Here is the genius study
As sidenote--before anyone ever does a study like this again, will you please contact me and let me know because I would do a study like this for HALF of what others are charging and I would come up with the same conclusion...simply by using common sense.
