Abstract
The Caloric Restriction (CR) diet in mammals has been shown to increase longevity and prevent metabolic disorders. Some of the benefits of CR include improved glucose homeostasis, namely improvements in glucose tolerance. Mice on the CR diet have a 30% reduction in food provided, as well as a fasting period between meals as they are only fed once a day. Hence the benefits of CR stem from both fasting and reduced calorie intake. In this study, we investigated if the fasting component of CR is responsible for the benefits of this diet in improving glucose homeostasis. In particular, we used glucose tolerance tests to show that varying durations of fasting affect the glucose tolerance of fasted mice differently. Shorter fasts improved glucose tolerance, while longer fasts showed similar or reduced tolerance compared to non-fasted mice. Ultimately, we observed that fasting may be responsible for a part of the benefits of CR, but it is not the only contributor to the advanced glucose tolerance and homeostasis of mice on CR.
