Short YouTube clip by Jim Katsoulis arguing that being thin and being thin-and-happy are different outcomes. He advises selecting a weight-loss process that also makes you happy, warning against extreme methods that sacrifice happiness for thinness.
Being thin and being thin and happy are two completely different things. And I'm going to assume that you want to be thin and happy. So in order to make that happen, you have to make sure that the process you use to become thin is one that also makes you happy. A lot of times, people don't pay attention to the process, and they do extreme things that make them miserable in order to lose weight. Just because you're thin does not mean you're going to be happy. It's all about how you make it happen. So make sure that the way you make it happen is a way that also makes you happy.
