Transcript of Fasting mimicking diet
FASTING MIMICKING DIET
DIETARY INTERVENTIONS
Calorie restricti
on
reducing calories 30-
40%
Dietary restricti
on
reducing macro-nutri-ents with or without re-
ducing calo-ries
Fasting
Intermittent or prolonged

CR IN MONKEYS HAS INCONSISTENT EFFECTS ON LONGEVITY
According to 2 existing studies
Colman RJ et al. Caloric restriction delays
disease onset and mortality in rhesus
monkeys. Science. 2009 Jul 10; 325(5937):201-4.
Mattison JA et al. Impact of caloric restriction on health and survival in rhesus monkeys from the NIA study. Nature. 2012
Sep 13;489(7415):318-21.
WHY SUCH A DIFFERENCE?
NIA study WNPRC study
Calorie intake17.3% from
protein, 5% from fat
15% from protein, 10%
from fat
Protein sourceCorn, wheat, soybean, fish, alfalfa meal
Lactalbumin
Source of carbsGround wheat,
corn, 3.9% sucrose
Corn, starch, 28.5% sucrose
Feeding regime Not ad libitum True ad libitum
IS THERE AN IDEAL RATIO?
RESTRICTING AMINO ACIDS EXTENDS
LONGEVITYYEAST: methionine (Met) restriction more than doubles lifespan; lack of serine (Ser), threonine (Thr), and valine (Val) extends lifespan and improved DNA repair
WORMS: lack of purified diets, eat-2 mutant lives longer in part because of reduced TOR and S6 kinase activity
FLIES: methionine restriction extends lifespan, carbohydrate to protein ratio plays a bigger role than just calorie intake
RODENTS: methionine and tryptophan restriction extend lifespan, protein restriction reduces spontaneous tumor formation, decreases mitochondrial reactive oxygen species, serum glucose, insulin, and IGF-I levels, improves hair growth
mTOR signaling pathway
HUMANS• Humans: analysis of 6,381 US men and women
aged 50 and above from NHANES III cohort showed reduction of cancer and all-cause risk mortality in people aged 50-65, but not in >65.
Levine ME et al, Low protein intake is associated with a major reduction in IGF-1, cancer, and overall mortality in the 65 and younger but not older population.
Cell Metab. 2014 Mar 4;19(3):407-17.
HUMANSNurses’ Health Study (85 168 women, 26 years) and Health Professionals’ Follow-up Study (44 548 men, 20 years) macronutrients in diet were scored
When intake mostly from ANIMAL-BASED PRODUCTS — the lowest carbs intake = higher all-cause mortality
VEGETABLE-BASED low carb regimen = lower all-cause and cardiovascular disease mortality
HIGHER PLANT-BASED PROTEIN intake correlates with lower ischemic heart disease and strokes (Health Professionals’ Follow-up Study)
Increase in ischemic heart disease correlated with high RED MEAT and high fat DAIRY INTAKE (Nurses’ Health Study)
Ecuadorean dwarfs deficient in growth hormone and IGF-1 don’t develop cancer or
diabetes
CENTENARIANS
SICILY – Mediterranean diet - three small meals comprised of small amounts of carbohydrates and meat and large amounts of seasonal fruits and vegetables, beans, olives, and olive oil
OKINAWA – diet rich in vegetables, fruits, and grains, only 9% of calories coming from proteins, mostly plant-based
Intermittent fasting extends longevity
MICE• 16 months age, 4 days twice a month• 11% median lifespan extension, no
effect on maximum lifespan• Decreases in visceral fat, glucose,
and IGF-1 levels• Improved femoral bone density, liver
regeneration, learning, memory and neurogenesis
Brandhorst S. et al., A Periodic Diet that Mimics Fasting Promotes Multi-System Regeneration, Enhanced Cognitive Performance, and Healthspan. Cell Metab. 2015 Jul 7;22(1):86-99.
HUMANS• 38 individuals, 19.8–67.6 years for the
control cohort and 27.6–70 years for the FMD cohort
• 5 days every month for 3 months• 9%–10% proteins, 34%–47% carbohydrates,
and 44%–56% • Blood glucose reduced by 11%, ketone
bodies increased 3.7-fold, Circulating IGF-1 was reduced by 24% by the end of the FMD period and remained 15% lower after resuming the normal diet, IGFBP-1 was increased 1.5-fold, 3% reduction in body weight, CRP levels were reduced
