Fast Weight Loss it is possible but it’s not advised
Fast weight loss is actually a physiological possibility. What is usually in contention is whether it is sustainable or not. Even of greater concern is how safely you can lose weight fast. There is really no exact definition of what fast weight loss is, though you will be considered to be losing weight fast if you are shedding more than 3-4 pounds of body weight in a week.
The characteristics of fad diets
Fad diets are quick weight-loss diet programs that are 'hot’ or popular at the time. They generally live to the meaning of the word 'fad'. Such quick weight-loss diets are characterized by a weak nutrition basis and usually an unproven belief. Many such fast weight loss diets have results but since they are not well founded on healthy functioning of our bodies the results are not sustainable.
Effects of rapid weight loss
Generally speaking rapid weight loss is associated with extreme dieting. It mostly involves the use of low calorie diets like the infamous cabbage soup diet. A low calorie diet is technically a diet that provides 800 calories or less daily. Though there are circumstances under which medically supervised rapid weight loss can be administered, it is generally considered a risk to health and is highly discouraged.
