FASTING MIMICKING DIET

DIETARY INTERVENTIONS

Calorie restricti

Dietary restricti

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

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
