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

    HOMA-IR is used to measure the severity of insulin resistance. Healthy Range: 1.0 (0.5-1.4) Less than 1.0 is optimal Above 1.9 indicates early insulin resistance Above 2.9 indicates significant insulin resistance

    Baseline and 3 days

  • Change From Baseline in Participant Glycogen-Like Protein-1 (GLP-1) When Fasting and Fed

    Baseline and 3 days

  • Change From Baseline in Participant Adiponectin When Fasting and Fed

    Baseline and 3 days

    Baseline and 3 days

  • Change From Baseline in Participant Hemoglobin When Fasting and Fed

    Baseline and 3 days

  • Change From Baseline in Participant Red Blood Cell Count (RBC) When Fasting and Fed

    Baseline and 3 days

  • Change From Baseline in Participant Hematocrit When Fasting and Fed

    Baseline and 3 days

  • Change From Baseline in Participant Platelet Count When Fasting and Fed

    Baseline and 3 days

    Baseline and 3 days

  • Change From Baseline in Participant Mean Platelet Volume (MPV) When Fasting and Fed

    Baseline and 3 days

  • Change From Baseline in Participant Bicarbonate When Fasting and Fed

    Baseline and 3 days

  • Change From Baseline in Participant Total Cholesterol (TC) When Fasting and Fed

    Baseline and 3 days

  • Change From Baseline in Participant Low-Density Lipoprotein Cholesterol (LDL-C) When Fasting and Fed

    Baseline and 3 days

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

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.
