Most people who have followed the 4 Day Diet are pretty positive about it. Most of them have been able to stick to the diet because it basically removes the boredom factor that dieting usually brings into our menus. There is a lot of variety with changes being introduced in your diet after every 4 days. So the motivation to stick onto the diet is pretty high. The fans of the 4 day diet also point out that because your diet keeps varying you tend to avoid the normal weight loss plateau which you reach with other diets and therefore lose more calories.
