Key takeaway
The Look AHEAD trial randomly put 5,145 adults aged 45 to 74 with overweight or obesity and type 2 diabetes in an intensive lifestyle programme or in diabetes education. After 4 years, 38.5% of the programme group reported good mobility, against 31.9%, and 20.6% had severe limits, against 26.2%. Both weight loss and better fitness helped explain the difference.
