[Carbohydrate-reduced diet and metabolism: about the influence of a 4-weeks isocaloric fat-rich, carbohydrate-reduced diet on body weight and metabolism (author's transl)]. 1979

P M Schürch, and A Reinke, and W Hollmann

The influence of a 4-weeks carbohydrate-reduced, fat-rich diet on 9 slightly overweighted men was investigated. Caloric and protein intake remained unchanged. 70% were fat, 20% carbohydrates. Glucose, cholesterol, triglycerids, serumproteins, urea, uric acid, sodium and potassium were measured in rest. At a 60 minutes bicycle ergometer test glucose, triglycerids, free fatty acids and glycerol were registrated before and after 20 and 60 minutes work. The intensity was 70% of the maximal oxygen uptake. These were the most important results: (1) Body weight decreased continuously. One of the causes is an elevated heat production. (2) Serum-protein and -glucose remained unchanged. Cholesterol and triglycerides were reduced. Serum-urea, -sodium and -potassium diminished continually. On the contrary, uric acid raised over the normal range. (3) Work performance was reduced for 20%. (4) Hypoglycemic values did not appear. The oxidation of fat by the working muscles, and fat mobilisation increased by a fat-rich diet.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D009765	Obesity	A status with BODY WEIGHT that is grossly above the recommended standards, usually due to accumulation of excess FATS in the body. The standards may vary with age, sex, genetic or cultural background. In the BODY MASS INDEX, a BMI greater than 30.0 kg/m2 is considered obese, and a BMI greater than 40.0 kg/m2 is considered morbidly obese (MORBID OBESITY).
D001835	Body Weight	The mass or quantity of heaviness of an individual. It is expressed by units of pounds or kilograms.	Body Weights,Weight, Body,Weights, Body
D002149	Energy Intake	Total number of calories taken in daily whether ingested or by parenteral routes.	Caloric Intake,Calorie Intake,Intake, Calorie,Intake, Energy
D002784	Cholesterol	The principal sterol of all higher animals, distributed in body tissues, especially the brain and spinal cord, and in animal fats and oils.	Epicholesterol
D004040	Dietary Carbohydrates	Carbohydrates present in food comprising digestible sugars and starches and indigestible cellulose and other dietary fibers. The former are the major source of energy. The sugars are in beet and cane sugar, fruits, honey, sweet corn, corn syrup, milk and milk products, etc.; the starches are in cereal grains, legumes (FABACEAE), tubers, etc. (From Claudio & Lagua, Nutrition and Diet Therapy Dictionary, 3d ed, p32, p277)	Carbohydrates, Dietary,Carbohydrate, Dietary,Dietary Carbohydrate

D005082	Physical Exertion	Expenditure of energy during PHYSICAL ACTIVITY. Intensity of exertion may be measured by rate of OXYGEN CONSUMPTION; HEAT produced, or HEART RATE. Perceived exertion, a psychological measure of exertion, is included.	Physical Effort,Effort, Physical,Efforts, Physical,Exertion, Physical,Exertions, Physical,Physical Efforts,Physical Exertions
