Intensity and duration of lifestyle interventions for long-term weight loss and association with mortality: a meta-analysis of randomised trials

What is it about?

•	An average 28 interventions (more than twice a month) in the first year achieved 3.67kg weight loss at one year. Interventions included seeing doctors, nurses, dietitians, nutritionist, and psychologists. 
•	Evidence that weight loss reduces mortality is from large, long term studies with frequent interventions in patients with cardiometabolic risk factors.
•	The effectiveness of simple lifestyle advice by medical practitioners or a limited number of interventions to achieve sustained weight loss is uncertain.
