Abstract

Objective: This study aimed to determine whether maternal high-fat diet (HFD) consumption in nonhuman primates alters the ability of offspring to adapt metabolically to nutrient and caloric challenges. Methods: Offspring from Japanese macaque dams fed either a control (CTR) diet or HFD were weaned onto a CTR diet creating two groups: maternal HFD (mHFD, n = 18) and maternal CTR (mCTR) diet (n = 12). Male and female offspring were exposed to a 5-day 30% calorie restriction and to a 35-day HFD challenge (HFDC), at 16 and 24 months of age, respectively. Caloric intake, body weight, and energy expenditure were measured. Results: Offspring from both groups showed similar body weight, food intake, and metabolic adaptations to a 5-day calorie restriction. mHFD offspring demonstrated increased food intake and early weight gain in response to a 35-day HFDC; however, group differences in weight dissipated during the challenge. Unlike mCTR animals, the mHFD group had a significant increase in fasting insulin after acute HFD exposure. Conclusions: The current findings indicate that offspring exposed to an mHFD show metabolic adaptations to calorie restriction that are largely similar to those of offspring exposed to a mCTR diet but show delayed adaptation upon exposure to an acute HFDC.
