The 3 Day Diet

Surprisingly surviving the test of time, the 3 Day Diet is another fad diet, dating back to 1985. Copies of the "3 Day Diet" continue to float around cyberspace, promising quick weight loss, cleansing, lower cholesterol and increased energy. However, no diet book exists to substantiate the science behind the "unique metabolic reaction."

Often mistakenly called The Cleveland Clinic Diet, the 3 Day Diet is a regimented plan that must be followed exactly for three days at a time, followed by normal eating for four or five days before opting to resume the plan again.

Followers of the 3 Day Diet are promised up to a 4.5kg (10lb) weight loss in three days, although realistically, most of that weight is likely due to fluid loss and not the more desirable fat loss. To achieve the proposed loss, exercise is not mentioned in the plan.
What you can eat

The 3 Day Diet is a very specific food plan that must be followed precisely. Portions must be eaten exactly as specified and dieters are warned not to overeat - otherwise the promised 4.5kg (10lb) weight loss may not be achieved. Likewise, dieters should not undereat, even if they are not hungry. The detailed plan does not mention or recommend any exercise.

How it works

By some unspecified force, the combination of the suggested foods included in this plan is supposed to create a unique metabolic reaction and boost fat burning.

Without an author or book, there is no documentation or explanation of how the 3 Day Diet food combinations burn fat, increase energy, cleanse the body or lower cholesterol.

As the name suggests, the 3 Day Diet lasts only three days, though it's said that it can be repeated indefinitely, as long as you alternate with four to five days of undefined "normal eating". The purpose of returning to your usual eating style is to keep your metabolism from slowing, reverting to fat-storing, starvation mode.

The secret behind all diets is to reduce the average calories you take. They try to make each diet seem unique, but it all boils down to reducing your average calories, and this diet does the same. It gives you very low calories for 3 days, then when you eat normally, you find our that your average is still lower than usual. It doesn't seem to be like a diet that you can follow for life. It is better to change your eating habits, eat healthy, and do it for ever than go ona diet then go back to eating with a vengence, to get even fatter than before.

Well you could always do the 3 day fast... It's pretty tough and if you splurge afterwards you end up getting fatter than before but if you manage to do the 3 day fast and eat normally then you feel loads better. You should read up on heaps of material should you decide to do it though... Your body starts to develop ketone antibodies and you lose brain function (brain needs sugar to function properly, you won't black out but you sorta get sleepy and feel tired), oh and of course get real hungry in the first day to second day. By the third day your body just CBF telling you to eat anymore. Benifits for me to do it is that, food taste much better and you last longer with less food as your body learns to adapt. As for weight loss, there's many other much more effective and less mental intensive methods out there though :P

i think after all types of diet you will eat again and your weight will increase

doing too much sport is the best
