Outcome Measures
Primary Outcomes (34)
Change From Baseline in Participant Glucose When Fasting and Fed
Baseline and 3 days
Change From Baseline in Participant Human Growth Hormone (HGH) When Fasting and Fed
Baseline and 3 days
Change From Baseline in Participant Insulin When Fasting and Fed
Baseline and 3 days

Eligibility Criteria
You may qualify if:
- The volunteer (male or non-pregnant female, any ethnicity) must be \>18 years of age.
- The volunteer must either have a body mass index of 25.0-35.0 kg/m2 or the combination of a body mass index of 18.5-24.9 kg/m2 and two or more previously or currently measured symptoms of the metabolic syndrome (fasting glucose≥110 mg/dL, triglycerides≥150 mg/dL, high-density lipoprotein cholesterol\<40 mg/dL in males or \<50 mg/dL in females, systolic blood pressure≥130 mmHg or diastolic blood pressure≥85 mmHg, or waist circumference≥40 inches in males or ≥36 inches in females \[glucose and cholesterol levels may be self-reported\]).
- The volunteer has not routinely participated in caloric restriction (deliberate limitation of caloric intake of \<80% than the FDA-recommended daily caloric intake) within the last 2 years, has not participated in extended fasting (\>12 hours at a time) for at least a year, and does not deliberately skip meals as a routine dietary practice.
You may not qualify if:
- Body mass index \<18.5 or \>35 kg/m2.
- Current active cancer treatment, treatment with immunosuppressive medications, or solid organ transplantation within 1 year.
- Presence of immunosuppressive disease, myocardial infarction, peripheral vascular disease, or stroke within the past year.
- Use of insulin.
