I have tried a lot of weight loss routines and diets. Some of them cost more money than they are worth. Actually, I would say most of the ones where you have to buy prepackaged foods and supplements are not worth the price you pay for them. I can cut back on calories for a couple weeks or months when I am dieting with almost no problems, but I worry that I am starving my body of nutrients that it needs to stay healthy.
I have read that some people do more harm to their bodies and their health when they are on fad diets than they would have done if they had never tried to lose weight. I think a weight loss powder might be what I need as long as it is loaded with good ingredients that my body needs.
