No the 3 day diet plan is not where you diet for just three days. It's actually an on again off again dieting back in the mid 80's and carries with it lots of controversial continuing verifiable authenticity. Considered a Fad Diet by many, mainly because of unsubstantiated proof of whether it actually works, the diet is a 3 day regimen that has to be done strictly by the book followed by normal eating routine for several days then done over again. Supposedly participants can lose 10 pounds in the 3 days of dieting and there is also no exercise needed.
Of the many different opinions about the 3 day diet plan one is that water is what makes up the 10 lost pounds in every instance of lost body weight. Give it a try. But as a warning no attempts of any weight loss regimen should be tried without first seeing a doctor to be sure that there are no underlying problems that may be aggravated or intensified as a direct result of using this plan.
This type diet is very strict and straying from the principles could mean not being able to achieve the 10 lb. weight loss goal, that is if this 3 day diet plan actually works. Remember it is highly controversial. In addition, dieters drink 4 cups of water or non-caloric drinks each day too.
While there is a straight forward reason for how the injured 10 pounds weight loss comes about, that being a unique metabolic reaction that boosts the natural fat burning process beyond normal capacities, there is no documentation or explanation of how the 3 Day Diet food combinations burn fat, increase energy, cleanse the body, or lower cholesterol. So does this 3 day diet plan actually work? Until certified documentation of verifiable authenticity is produced, you'll have to be the judge.
