Additional effects of exercise to hypocaloric diet on body weight, body composition, glycaemic control and cardio‐respiratory fitness in adults with overweight or obesity and type 2 diabetes: A systematic review and meta‐analysis
Authors' conclusion
Based on limited data, we did not find additional effects of exercise to hypocaloric diet in adults with overweight or obesity and type 2 diabetes on body weight, body composition or glycaemic control, while cardio-respiratory fitness improved.
