Effect of intermittent fasting and refeeding on insulin action in healthy men
"This experiment is the first in humans to show that intermittent fasting increases insulin-mediated glucose uptake rates, and the findings are compatible with the thrifty gene concept."

A controlled trial of reduced meal frequency without caloric
restriction in healthy, normal-weight, middle-aged adults
"Conclusions:Normal-weight subjects are able to comply with a 1 meal/d
diet. When meal frequency is decreased without a reduction in overall
calorie intake, modest changes occur in body composition, some
cardiovascular disease risk factors, and hematologic variables.
Diurnal variations may affect outcomes."

Intermittent fasting dissociates beneficial effects of dietary
restriction on glucose metabolism and neuronal resistance to injury
from calorie intake.
fasting resulted in beneficial effects that met or exceeded those of
caloric restriction including reduced serum glucose and insulin levels
and increased resistance of neurons in the brain to excitotoxic
stress. Intermittent fasting therefore has beneficial effects on
glucose regulation and neuronal resistance to injury in these mice
that are independent of caloric intake."
Caloric restriction increases learning consolidation and facilitates
synaptic plasticity through mechanisms dependent on NR2B subunits of
the NMDA receptor.
"Here we have examined the effects
of maintaining mature mice on a long-term intermittent fasting diet
(L-IFD). We found that L-IFD enhances learning and consolidation
processes. We also assessed the long-term changes in synaptic
efficiency in these animals. [...] These data provide a
molecular and cellular mechanism by which L-IFD may enhance cognition,
ameliorating some aging-associated cognitive deficits."
Cardioprotective effect of intermittent fasting is associated with an
elevation of adiponectin levels in rats.
"It has been reported that dietary energy restriction, including
intermittent fasting (IF), can protect heart and brain cells against
injury and improve functional outcome in animal models of myocardial
infarction (MI) and stroke. Here we report that IF improves glycemic
control and protects the myocardium against ischemia-induced cell
damage and inflammation in rats."
Beneficial effects of intermittent fasting and caloric restriction on
the cardiovascular and cerebrovascular systems.
"Both IF and CR enhance cardiovascular and brain
functions and improve several risk factors for coronary artery disease
and stroke including a reduction in blood pressure and increased
insulin sensitivity. Cardiovascular stress adaptation is improved and
heart rate variability is increased in rodents maintained on an IF or
a CR diet. Moreover, rodents maintained on an IF regimen exhibit
increased resistance of heart and brain cells to ischemic injury in
experimental models of myocardial infarction and stroke."
Caloric restriction and intermittent fasting: two potential diets for
successful brain aging.
"In this review article we describe evidence
suggesting that two dietary interventions, caloric restriction (CR)
and intermittent fasting (IF), can prolong the health-span of the
nervous system by impinging upon fundamental metabolic and cellular
signaling pathways that regulate life-span."
Interleukin-6, C-Reactive Protein and Biochemical Parameters during
Prolonged Intermittent Fasting
"Conclusion: Our results demonstrate that
prolonged intermittent fasting in a model like Ramadan has some
positive effects on the inflammatory status of the body and on the
risk factors for cardiovascular diseases such as homocysteine, CRP and
Alternate-day fasting and chronic disease prevention: a review of
human and animal trials
"The findings in animals suggest that ADF may effectively
modulate several risk factors, thereby preventing chronic disease, and
that ADF may modulate disease risk to an extent similar to that of CR.
More research is required to establish definitively the consequences
