Maintaining weight loss is key, even more important than actually losing the weight in the first place. I mean if you see success with Jenny Craig for example, great, until you gain all the weight back because you used prepackaged foods and never actually learned about healthier habits and moreover how to maintain your results in general. You have to exercise to have any kind of healthy and lasting diet plan. But you also need to remember the basic rules of eating more fruits and vegetables, having balance in good fats, not starving yourself, etc. And you need to stick to it. An occasional deviation is not a bad thing, it can even help so that you don’t binge. But you have to remember basic rules that you cannot learn through prepackaged meals, and frankly you have to be stick to any given diet for life. If you don’t or can’t, you will end up yo yo dieting, which can actually be quite detrimental in general to your health. This is why even famous people like Oprah for example have not maintained or otherwise really succeeded. They went to extremes and didn’t remember very basic rules in maintaining. It was all about the initial weight loss, too much in fact.
