Want to slow down the aging process, live longer, feel younger? Eat less. Partial results from the most comprehensive study on calorie restriction (a 2-year randomized controlled trial including 200+ healthy adults looking at the effects of calorie restriction on metabolism) in humans and its effect on slowing the aging process have just been released. Tests assessing overall metabolism and biological markers for aging were performed in 53 participants between ages 21 and 50. 34 of the participants reduced their calorie intake by 15%, while 19 ate as usual. Results showed that those on the reduced calorie regimen used energy much more efficiently while sleeping (even when weight loss was taken into account) and experienced a reduced metabolic rate and a significant decrease in damage due to aging. Cell Metabolism →Takeaway: Reduced calorie diets in animals show incredible benefits in slowing aging and extending life. Calorie restriction in mice has shown to extend…

Intermittent fasting (typically defined as going 12 to 18 hours a day without food) positively impacts the gut microbiome and protects against central nervous system (CNS) autoimmunity.  A recent study in mice found that IF increases gut bacteria richness and diversity (resulting in an increase in Lactobacillaceae, Bacteroidaceae, and Prevotellaceae families), and positively alters gut microbiome composition and antioxidative metabolic pathways. When the gut microbiome from IF mice was transferred to mice who were immunized with a multiple sclerosis (MS) model, the MS mice were protected. Cell Metabolism →Takeaway: IF has shown in this study and in others to positively impact the gut microbiome, and therefore, could be a viable everyday practice to help improve microbial balance. Intermittent energy restriction (IEF – eating 500 calories per day 1 to 2 days out of the week) was proven in recent studies to help ameliorate MS in human subjects and may be an avenue to…
