Placebo Comparator: Placebo Starch
Yogurt with about 45 g/day of placebo starch (amylopectin).
Dietary Supplement: Amylose
One group of participants will consume a yogurt containing 45 g of amylose (the slowly digesting starch) for 3 months.
Experimental: Experimental Starch
Yogurt with about 45 g/day of slowly digestible starch (amylose).
Dietary Supplement: Amylopectin
The second group will consume a yogurt containing 45 g of a different starch called amylopectin (the "placebo") for 3 months.
- Insulin Sensitivity and Secretion [ Time Frame: 3 months ]Insulin sensitivity and secretion will be assessed via a Frequently Sampled Intravenous Glucose Tolerance Test (FSIGTT).
- Body Composition [ Time Frame: 3 months ]DXA and MRS will be performed to measure body composition (adipose, muscle, bone mineral content) and to measure hepatic and intramyocellular lipids, respectively.
- Gut Microbiota [ Time Frame: 3 months ]Stool samples will be collected and fecal bacteria diversity will be measured in conjunction with metagenomic analysis.
- Satiety [ Time Frame: 3 months ]Satiety hormones will be measured following ingestion of a standardized smoothie (Standard Meal Test). Satiety will be measured through visual analogue scales (VAS), remote food photography, and a food intake test.
- Hunger [ Time Frame: 3 months ]Hunger will be measured through visual analogue scales (VAS), remote food photography, and a food intake test.
