title: Effects of a high lipidic diet on murine energetic reserves in food deprivation.
abstract: Female mice were fed for one month either control or cafeteria diets. Then they were subjected to food deprivation for up to 36 hours and their weight loss, tissue lipid, glycogen and protein were determined together with their plasma glycose, amino acids, urea, lipoproteins and ketone bodies. Cafeteria mice were able to cope with prolonged starvation with altered plasma composition and important loss of lipids and protein, sparing to a certain degree their glucose and amino acids. Control-fed mice, however, showed a intense ketosis and significant losses of nitrogen. The results obtained showed a higher ability of cafeteria mice to handle and use lipids, that evolves in a better suitability to resist food deprivation with less extensive alterations in their fuel and nitrogen homeostasis.
