Effect of 3-hydroxybutyrate in obese subjects on very-low-energy diets and during therapeutic starvation. 1983

G L Pawan, and S J Semple

Sodium DL-3-hydroxybutyrate was administered to obese subjects (more than 150% ideal body-weight) who were either receiving a 2 . 5 MJ (600 kcal) diet containing 34 g protein on one day with a total fast (water and vitamins only) on the next day, for 21 days, or were undergoing therapeutic starvation for 14 days. Both intravenous and oral hydroxybutyrate significantly reduced net body protein loss as measured by total urinary nitrogen and 3-methylhistidine excretion. Hydroxybutyrate administration did not significantly affect the rate of weight-loss but seemed to increase the fat/lean ratio of the tissue loss. The subjects experienced no untoward effects and none complained of hunger while receiving 3-hydroxybutyrate.

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).

Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
