Energy balance and mitochondrial function in liver and brown fat of rats fed “cafeteria” diets of varying protein content
NJ Rothwell, MJ Stock, RS Tyzbir - The Journal of nutrition, 1982 - Elsevier
Rats fed “cafeteria” diets with low (7%, LP) normal (23%, NP) or high (33%, HP) protein
contents showed increases in metabolizable energy intake (kJ/kg 0.75, 23–41%) and in
energy expenditure (36%) compared to controls fed stock diet (27% protein). The high
metabolic rates were inhibited by β-adrenergic blockade with propranolol. All rats fed
cafeteria diets deposited more fat than controls, but the LP diet depressed growth, and these
animals also showed the lowest energetic efficiency. Brown adipose tissue (BAT) mass and …
