[PDF][PDF] A ketogenic diet extends longevity and healthspan in adult mice

…, FG Haj, K Baar, GA Cortopassi, JJ Ramsey… - Cell metabolism, 2017 - cell.com
Calorie restriction, without malnutrition, has been shown to increase lifespan and is associated
with a shift away from glycolysis toward beta-oxidation. The objective of this study was to …

Restriction of energy intake, energy expenditure, and aging

JJ Ramsey, ME Harper, R Weindruch - Free Radical Biology and Medicine, 2000 - Elsevier
Energy restriction (ER), without malnutrition, increases maximum life span and retards the
development of a broad array of pathophysiological changes in laboratory rodents. The …

An epidemic of obesity has affected large portions of the world, increasing the risk of developing
many different age-associated diseases, including cancer, cardiovascular disease, and …

Effects of short-and medium-term calorie restriction on muscle mitochondrial proton leak and reactive oxygen species production

L Bevilacqua, JJ Ramsey, K Hagopian… - American Journal …, 2004 - journals.physiology.org
Reductions in cellular oxygen consumption (V̇o 2 ) and reactive oxygen species (ROS)
production have been proposed as mechanisms underlying the anti-aging effects of calorie …

Caloric restriction increases gluconeogenic and transaminase enzyme activities in mouse liver

K Hagopian, JJ Ramsey, R Weindruch - Experimental gerontology, 2003 - Elsevier
Long-term caloric restriction (CR) has been shown to extend maximum life span in laboratory
rodents. We investigated the activities of gluconeogenic and transaminase enzymes in the …

Long-term caloric restriction increases UCP3 content but decreases proton leak and reactive oxygen species production in rat skeletal muscle mitochondria

L Bevilacqua, JJ Ramsey, K Hagopian… - American Journal …, 2005 - journals.physiology.org
Calorie restriction (CR) without malnutrition increases life span and delays the onset of a
variety of diseases in a wide range of animal species. However, the mechanisms responsible …

Caloric restriction mimetics: metabolic interventions

…, RA Floyd, JB Halter, JJ Ramsey… - The Journals of …, 2001 - academic.oup.com
Caloric restriction (CR) retards diseases and aging in laboratory rodents and is now being
tested in nonhuman primates. One way to apply these findings to human health is to identify …
