About

The purpose of this study is to determine the short-term effect of a nutritional program consisting of a yerba mate supplement, fiber supplement, and intermittent fasting on glycemic variability in men and women with risk factors for impaired fasting glucose.

Full description

The purpose of this study is to determine the effect of a nutritional program which combines two different supplements (a yerba mate extract supplement and a fiber-based, vitamin-rich nutritional supplement) and intermittent fasting on glycemic variability and glycemic control in men and women with risk factors for impaired fasting glucose.

This study will be an exploratory pilot study with one screening visit, one baseline visit followed by a baseline phase, two intervention phases, and one follow-up visit. During the baseline phase, subjects will follow their regular dietary routines. During the 4-day Phase 1, subjects will take the yerba mate supplement once per day and the fiber supplement twice per day. During the 4-day Phase 2, subjects will continue the supplement regimen from Phase 1, while incorporating daily intermittent fasting for approximately 16 hours and eating for 8 hours. A continuous glucose monitor will be worn by each subject to continuously measure glucose throughout the study period.

• Weight loss or gain > 4.5 kg within 90 days of Visit 1.
• Currently or planning to be on a weight loss or weight gain / muscle-building regimen program during the study.

• Unstable use of medications that affect blood glucose levels whereby stable is defined as no change in regimen within 90 days of Visit 1.
• Use of oral or injectable steroids (topical and inhaled are allowed) within 90 days of Visit 1
• Use of fiber supplements or intentionally increasing fiber intake within 30 days of Visit 1
• Use of yerba mate containing products (beverage, supplement) within 30 days of Visit 1
• Exposure to any non-registered drug product within 30 days prior to Visit 1
• Use of vitamin C-containing supplements (including multivitamins) within 24 hours of Visit 2 and during the study intervention period.
• Use of products containing salicylic acid (skin-care products are allowed if not used on the area surrounding the sensor) within 24 hours of Visit 2 and during the study intervention period.
• Use of topical marijuana or hemp products within 24 hours of Visit 2 and during the study intervention period.
• 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 during the study period.
• Recent history (within 12 months) of alcohol or substance abuse.
• Has a condition the Clinical Investigator believes would interfere with his/her ability to provide informed consent, comply with the study protocol, which might confound the interpretation of the study results, or put the subject at undue risk.
