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 …

The rhythms in the expression of circadian clock genes are affected by calorie restriction (CR), a dietary paradigm known to increase lifespan. In our current study, we show that circadian rhythms are influenced by sex and the effects of CR are different between males and females. In particular, we found a group of clock genes which showed a sex-dependent difference in expression, as well as in response to CR (Rev-Erb α, Ror γ and both Cryptochromes: Cry1 and Cry2 genes). Two clock genes showed no difference in expression but their response to CR showed sexual dimorphism (Ror α and Rev-Erb …
