Self-Selective Alimentation A New Experimental Model: Separate Feeding

Schedule of Protein Ingestion and Circadian Rhythm of Certain Hepatic Enzyme Activities Involved in Glucose Metabolism in the Rat

“…In a previous paper (33) we observed both in growing rats and in depletedrepleted adult rats, either receiving a mixed diet ad libitum (8 % protein) or a protein meal (1.1 g protein) given at different hours in the day, with free access to a protein-free diet (separately fed) (32) that when the protein meal was ingested during the lighted period (07:00-19:00), growth, weight repletion and nitrogen retention were lower than in rats consuming protein during darkness (19:00-07:00). Moreover, in the latter case, tissue and liver lipid levels were increased and the circadian rhythm of liver glycogen was modified.…”
