title: Influence of dietary fats on weight gain in albino rats.
abstract: Carbon-chain length and degree of saturation of dietary fat may influence weight gain. To examine this hypothesis we randomly allotted 100 male, 30-day old, albino rats to each of four groups. Each group was fed, ad libitum, a diet containing, as the only source of fat, either lard (L) or safflower oil (SO) (representing saturated and polyunsaturated fat respectively) or groundnut oil (GO) or coconut oil (CO) (representing long-chain and medium-chain triglycerides respectively). At the end of 90 days it was found that rats fed SO consumed more food than those fed L enriched diet (P < 0.001) but the weight gain was similar in the two groups. Similarly rats fed GO-containing diet ate more than those fed diet containing CO (P < 0.001), yet weight gain was similar. Thus it appears that carbon-chain length and degree of saturation of dietary fat does not influence weight gain in rats fed an ad libitum diet.
