Objective This crossover experimental study examined the acute effects of high‐sugar/low‐fiber (HSLF) vs. low‐sugar/high‐fiber (LSHF) meals on sedentary behavior (SB) and light‐plus activity (L+) in minority adolescents with overweight and obesity. Methods 87 Latino and African American adolescents (mean age = 16.3 ± 1.2 years, mean BMI z ‐score = 2.02 ± 0.52, 56.8% Latino, 51.1% male) underwent two experimental meal conditions during which they consumed HSLF or LSHF meals. Physical activity and SB were measured using accelerometers, and blood glucose and insulin were collected every 30 minutes over 5 hours. Mixed models were used to examine the temporal trends of SB and L+, whether the temporal trends of SB and L+ differed by meal condition, and the influence of blood glucose and insulin on the activity behaviors. Results SB and L+ fluctuated over time during the HSLF condition but were stable during the LSHF condition. SB and L+ were influenced by the blood glucose response to the HSLF meals. Insulin did not influence SB or L+ in either meal condition. Conclusions Sugar and fiber content of meals can have differing acute impacts on activity behaviors in minority adolescents with overweight and obesity, possibly due to differing metabolic responses.
