The 3 Day Cardiac Diet was supposedly developed by the Birmingham Hospital in Alabama, though the hospital does not admit its role in the origin of the plan. The 3 day cardiac diet has also been attributed to the Cleveland Clinic in Ohio and the Mayo Clinic in Minnesota.
The story is that the 3 Day Cardiac Diet was designed for patients who needed to lose up to 10 lbs weight quickly so they could have surgery.
The 3 Day Cardiac Diet has set menu plans for breakfast, lunch and dinner for three days. Each day is limited to about 800 calories. While some claim that there is a special ?chemical reaction,? much of the weight loss benefit is likely obtained by the restricted calorie intake. Also, there are very few carbs on the diet which leads to water loss.
