| Study Title | The Metabolic Benefits of Short Cycles of Very Low Caloric Intake are Dependent on Diet Composition in Middle-Aged Mice |
| Study Summary | Diet composition, calories, and fasting times contribute to maintenance of health. Here, middle-aged mice were maintained for 5 months on 4:10 feeding cycles, consisting of 4 days of very low-calorie intake (VLCI) achieved with either standard laboratory chow (SD) or a fasting mimicking diet (FMD), followed by 10 days of ad libitum access to SD. Fat and lean mass loss was accompanied with improved performance, glucoregulation, and metabolic flexibility independent of diet composition. However, only the 4:10/SD cycles elicited a long-lasting metabolomic reprograming in serum and liver that was preserved six days after refeeding. Challenged with an obesogenic diet, cycles of VLCI achieved with either high-fat diet (HFD) or FMD during the low-calorie period did not prevent diet-induced obesity nor did they elicited a long-lasting metabolic memory, despite achieving modest metabolic flexibility. Our results highlight the importance of diet composition in mediating the metabolic benefits of short cycles of VLCI. |
