Adherence

Group cognitive behavioural therapy (group-CBT) does not improve long-term weight maintenance or reduce weight regain in overweight or obese adults with type 2 diabetes following a very low calorie diet (VLCD).

If you have type 2 diabetes and have successfully lost weight using a very low calorie diet, adding group cognitive behavioural therapy is unlikely to help you keep the weight off compared to standard diabetes care alone. Standard care includes regular visits with doctors and dietitians, which may already provide enough support for maintenance. Focus on maintaining the dietary habits and physical activity established during the weight loss phase rather than expecting psychological therapy to prevent regain.

WeakRefutesHIGH confidence
Despite increased treatment contact, a group-CBT programme for long-term weight maintenance after an initial ≥5% weight loss from dieting in obese individuals with type 2 diabetes was not superior to usual care alone.
