Effects of the WHRonly+ PGS and weight-loss diets on changes in fasting glucose and HOMA-B during the 2-year intervention in white participants. Values were means±SEs, adjusted for age, sex, baseline BMI, weight loss at 2 years, and baseline values of the respective outcomes in the general linear models. HOMA-B were log-transformed before analysis. High-Pro, high protein; Avg-Pro, average protein; HOMA-B, homeostasis model assessment of β cell function; T, tertile. Panel a: changes in glucose; panel b: changes in HOMA-B.
