[Body potassium and skinfold thickness in an isocaloric, fat-rich diet (author's transl)]

Nine partly weak overweighted sport students got a fat rich isocaloric diet (70% fat, 20% protein, 10% carbohydrates) for three weeks. Body weight, body potassium and skinfold thicknesses were measured. A constant loss of body weight was the result. Lean body mass and body fat decreased. It is supposed that protein is used for gluconeogenesis if carbohydrate reduction is nearly total.
