简要总结
The purpose of this study is to assess the safety and efficacy of time-restricted feeding (eating within an 8-hour window) for improving physiological function (vascular, motor, cognitive and metabolic function) in healthy middle-aged and older adults.
详细描述
Overall, the proposed research project has the long-term potential to influence clinical practice by establishing novel therapies for treating multiple domains of age-associated physiological dysfunction and thereby reducing the risk of clinical disease and disability.

入排标准
入选标准
- •Ability to provide informed consent
- •Baseline brachial flow-mediated dilation (FMD) \< 6%Δ (rationale: non-invasive screening to ensure exclusion of subjects with exceptionally high baseline endothelial function.
- •Ability to perform motor and cognitive tests (e.g., can rise from a chair, walk for 2 min, climb 10 stairs)
- •Women will be confirmed as postmenopausal (either natural or surgical) based on cessation of menses for \>1 year.
排除标准
- •Ages \<55 years or ≥80 years
- •Occupation that requires night-shift work or abnormal hours that would disrupt eating schedule
- •Dietary habit of regularly skipping meals, already eating within a \~10 hour window, or any other form of restrictive eating.
- •Unable to adhere to an 8 hour eating window for the length of the study period
- •Participation in regular vigorous aerobic/endurance exercise (\>3 vigorous bouts/week)
- •Not weight stable in the prior 3 months (\>2 kg weight change).
- •Body mass index (BMI) \>40 kg/m\^2 (rationale: vascular function measurements can be inaccurate in severely obese subjects)
- •Current smoking
- •Diagnosis of a chronic clinical disease (e.g., coronary artery/peripheral artery/cerebrovascular diseases, diabetes, chronic kidney disease requiring dialysis, neurological disorders or diseases that may affect motor/cognitive functions \[multiple sclerosis, Parkinson's disease, polio, Alzheimer's disease, dementia or other brain diseases of aging\]), except hypertension and hyperlipidemia.
- •Having unstable angina, acute myocardial infarction, coronary angioplasty, or aorto- coronary bypass surgery as defined by the occurrence of an event, symptom, surgery, or change in medication and/or dosage within 3 months prior to enrollment.
