The Sheekey Science Show | Caloric Restriction - latest human data @TheSheekeyScienceShow | Uploaded March 2022 | Updated October 2024, 4 days ago.
Calorie restriction (CR) is the chronic reduction of total calorie intake without malnutrition and this can range from 20-40%. CR has been shown in many different model organisms to extend lifespan and these effects appear to get more modest the closer the species is to humans.
But, how effective is it in humans and are there any safety consequences? Well, in this video I take a look at some recent data published from the CALERIE trial, a 2-year study where human patients underwent on average a 14% CR. In particular they focus on immune system aging such as the thymus and identify the gene PLAG2G7 as an interesting target to follow-up.
