I'm 20, and have had a weight problem for most of my life. For most of you here, this is going to be horrible, but... I've done Atkins.
I lost 48lbs. on it, but have rebounded so fast it's scary.
Since then, I've lost my appetite for red meat entirely, and always get white meat, like chicken or turkey. I've started in on the veggie lifestyle, though I think I'm at the semi-vegetarian level at this point (though I'm not sure on that, though). I've come to terms with my emotions and inner self, but not with my physical body. I'm at risk for several conditions, including colon cancer, diabetes, and depression. I'm 5'6", 189 lbs, and want more than anything to get healthy and prevent my medical history from taking over my life.
Thanks, and from all that I've read, this lifestyle will certainly help my health!
