The Schwarzbein Principle Diet is a low-carbohydrate, high-protein weight loss diet. It is based on a book by Diana Schwarzbein, MD, which was originally published in 1999.

Low-carbohydrate, high-protein diets such as the Schwarzbein Principle Diet are extremely popular in North America. As many as one out of every eight North Americans has used this type of diet to lose weight.

How does it work?

The Schwarzbein Principle Diet’s main strategy is to eliminate or reduce “bad carbs,” carbohydrates that have a “high glycemic index.” High glycemic index foods raise blood sugar levels quickly after the food is eaten. Some people think that high glycemic index foods cause excessive insulin secretion resulting in fat accumulation, obesity, diabetes, heart disease, and other harmful outcomes. However, there continues to be significant debate and research to determine if a low glycemic index diet can actually prevent these outcomes.

The Schwarzbein Principle Diet has two phases called “healing” and “maintenance.” During the healing phase, carbohydrates are severely restricted; however, leafy green vegetables are allowed during this phase. The maintenance phase allows reintroduction of a moderate amount of carbohydrates to the diet. This phase is meant to continue indefinitely.

SCHWARZBEIN PRINCIPLE DIET Uses & Effectiveness What is this?

Insufficient Evidence for:

  • Weight loss. Although low-carbohydrate, high-protein diets have been evaluated in well-designed studies on people, the specific Schwarzbein Principle Diet plan has not been evaluated in this manner. More evidence is needed to rate the effectiveness of the Schwarzbein Principle Diet for weight loss.


There isn’t enough reliable information to know if the Schwarzbein Principle Diet is safe or what side effects, if any, it might cause. Since carbohydrates, including fiber are restricted from the diet, there is some concern that it could cause constipation for some people.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Not enough is known about the use of the Schwarzbein Principle Diet during pregnancy and breast-feeding. Stay on the safe side and avoid use.
