  3. Subject has a clinically significant medical condition that, in the opinion of the Investigator, could interfere with the interpretation of the study results.
  4. Subject has uncontrolled hypertension (systolic blood pressure ≥160 mm Hg and/or diastolic blood pressure ≥100 mm Hg) at screening.
  5. Subject has a history of cancer in the prior 5 years, except non-melanoma skin cancer or carcinoma in situ of the cervix.
  6. Subject has had a weight change of +/-4.5 kg (10 lbs) in the previous 3 months.

  8. Subject has a history of bariatric surgery, is currently taking a weight loss drug, or is actively attempting to lose or gain body weight.
  9. Subject has taken a proprotein convertase subtilisin kexin type 9 (PCSK9) inhibitor agent within 12 weeks prior to screening.
  10. Subject has unstable use (defined as initiation or change in dose) of the following lipid-altering medications within 4 weeks prior to screening: bile acid sequestrants, fibrates, niacin (drug form), statins, ezetimibe, bempedoic acid, or omega-3-ethyl ester drugs.
  11. Subject has taken any hypoglycemic medications within 4 weeks prior to screening including: insulin, sodium-glucose cotransporter-2 (SGLT2)-inhibitors, alpha-glucosidase inhibitors, biguanides, thiazolidinediones, dipeptidyl peptidase-4 (DPP-4) inhibitors, meglitinides, sulfonylureas, glucagon-like peptide-1 (GLP-1) receptor agonists, GLP-1/glucose-dependent insulinotropic polypeptide (GIP) modulators.

  13. Subject has used systemic corticosteroids within 4 weeks prior to screening.
  14. Subject has taken dietary supplements meant to regulate carbohydrate or lipid metabolism or body weight, within 4 weeks of screening, including, but not limited to, chromium picolinate, ginseng, starch blockers, omega-3 fatty acid supplements (e.g., flaxseed, fish or algal oils), red rice yeast supplements, garlic supplements, soy isoflavone supplements, niacin or its analogues at doses >400 mg/day, plant sterol or stanols, and/or irregular or inconsistent use of Metamucil® or other viscous fiber-containing supplements (consistent, daily use up to 1 teaspoon of a viscous-fiber supplement is acceptable).
  15. Subject has signs or symptoms of an active infection of clinical significance or has taken antibiotics within 5 days prior to any visit (washout is permitted for re-scheduling of the clinic visit).
  16. Subject has an allergy, sensitivity or intolerance to any components of the study products.
  17. Subject is a female who is pregnant, planning to be pregnant during the study period, lactating, or is of childbearing potential and is unwilling to commit to the use of a medically approved form of contraception throughout the study period.
  18. Subject has been exposed to any non-registered drug product within 30 days prior to screening.
  19. Subject has a current or recent history (within 12 months prior to screening) or strong potential for illicit drug or excessive alcohol intake defined as >14 drinks per week (1 drink = 12 oz beer, 5 oz wine, or 1.5 oz hard liquor).
  20. Subject has a condition the Investigator believes would interfere with his or her ability to provide informed consent, comply with the study protocol, which might confound the interpretation of the study results or put the person at undue risk.
