Brisk walking is the most popular activity for obesity management for adults. We aimed to identify whether participant age, sex and body mass index (BMI) influenced the effectiveness of brisk walking.A search of 9 databases was conducted for randomized controlled trials (RCTs). Two investigators selected RCTs reporting on change in body weight, BMI, waist circumference, fat mass, fat-free mass, and body fat percentage following a brisk walking intervention in obese adults.Of the 5072 studies screened, 22 met the eligibility criteria. The pooled mean differences were: weight loss, -2.13 kg; BMI, -0.96 kg/m2; waist circumference, -2.83 cm; fat mass, -2.59 kg; fat-free mass, 0.29 kg; and body fat percentage, -1.38
