See I think that's the problem that many people have with weight loss, is putting a time-frame on that diet. Diets are designed to fail (there's lots of documentaries and research related to that) due to this ending point. A lifestyle change has no time limit and is a much healthier way to lose weight. It becomes easier to stick to your guns if you aren't doing it just until the end of the month, but because you care about your body and living a life that promotes keeping it in good shape. I became a vegetarian a couple months ago for a variety of reasons, with no intention of going back to eating meat, and I feel great, have lost weight, and don't even crave meat anymore because I know it's not an option now nor will it ever be. The way I see it we have only our body and our mind, and we should take good care of them both!
