First, lets try to understand what a diet is. I thought of a nice neat acronym for this 4 letter word.
A diet can stand for a desperate ill-faded exotic trap. Ok, now to break this down for better understanding. Diets can be desperate, because an individual wants to get that weight off now. I say that they are also ill-faded because they signify something temporary or short term. Diets are exotic, since they can get or have a lot of hoopla in advertising that makes them look good to the needy individual. I say that diets can be a trap, since in a lot of cases, once an individual looses the desired weight, they return to past behaviors that end up returning them to the weight they once were thus making the individual start the diet all over again.
Now, as for a change in lifestyle, and using Herbalife as an example, once an individual reaches their desired weight loss goal, the weight loss program would then become a weight management program to assist the individual in maintaining a proper weight range. Also, the individual would be on a regiment of supplements to provide proper cellular nutrition to help maintatin a healthier lifestyle.
By deciding to change your lifestyle, you are embarking down a road that will provide you a stronger, healthier foundation for the rest of your life and not just the interim like a diet would do.
Which path do you want?
