The cabbage diet, or otherwise cabbage soup diet is based on high content of cabbage and other vegetable high in fiber, and a limited range of permissible foods.

The cabbage soup diet is based on the idea that cabbage has "miraculous" properties in terms of burning fat. Although there is not any official version of the diet, all variations are based on large quantities of cabbage soup and little of anything else.

Atkins diet is the brainchild of cardiologist Robert C. Atkins, which became very popular with his book "The Revolutionary Diet of Dr. Atkins", which was published in 1972. The diet promotes a nutritional profile of low carbohydrate, and high protein and fat.

The theory of the Atkins diet is based on the fact that the sugars and simple carbohydrates increase the level of insulin by facilitating the storage of fat. Deprivation of carbohydrates leads to burn the stored fat to produce energy.
