Brief Summary:
Diabetes is one of the greatest challenges faced by healthcare services worldwide. It is associated with serious complications such as heart attacks, stroke, and peripheral artery disease as well as kidney disease, eye disease, and nerve dysfunction. Data from weight loss with bariatric surgery suggest that with the appropriate intervention, it should be possible to reverse diabetes and that the earlier the intervention occurs, the greater the chances of placing diabetes into remission. There is now a need to translate this knowledge into the medical care of younger patients with early diabetes who are overweight/obese. The aim of this study is to see if younger adult patients with overweight/obesity and type 2 diabetes who are participants in a programme incorporating a low energy diet and physical activity (lifestyle) will lower their weight, cardiovascular risk and improve their glycaemic control as compared to the usual care.

Condition or disease Intervention/treatment Phase
Diabetes Mellitus, Type 2 Dietary Supplement: Low Energy Diet Not Applicable

Detailed Description:
The aim of the proposed study is to conduct a pragmatic randomised controlled clinical trial randomising young adult patients with obesity and type 2 diabetes to an intervention incorporating a low calorie diet and physical activity or usual care. The investigators hypothesise that patients in the low calorie intervention arm will have greater weight reduction leading to significant improvement in glycaemic control and cardiovascular risk. The primary outcome will be weight loss. The low calorie diet intervention arm is designed to achieve and maintain significant weight loss through decreased calorie intake, increased physical activity, and behaviour change. Usual care will include routine advice about diet and physical activity. Secondary outcomes include diabetes control, body composition, and quality of life.

Arm Intervention/treatment
Experimental: Lifestyle Intervention
The intervention includes the use of Low Energy Diet replacement products in combination with physical activity, followed by gradual introduction of food, and increasing physical activity. Behavioural support for the lifestyle intervention will also be provided.
Dietary Supplement: Low Energy Diet
Low Energy Diet

No Intervention: Usual Care
This will be based on current clinical practice aiming to reduce diabetes symptoms and complications, and general recommendations on diet and physical activity.



Primary Outcome Measures :
  1. Weight loss [ Time Frame: 12 months ]
    Weight change (weight in kilograms)


Secondary Outcome Measures :
  1. Glycaemic control [ Time Frame: 12 months ]
    HbA1c measured biochemically (percentage units)

  2. Patient reported outcomes [ Time Frame: 12 months ]
    Euro-QoL-5D


Other Outcome Measures:
  1. Insulin sensitivity/resistance [ Time Frame: 12 months ]

    Fasting Insulin and Glucose levels will be combined to calculate:

    Homeostatic model assessment (HOMA-IR)


  2. Body Mass Index [ Time Frame: 12 months ]
    Weight and height measures will be used to calculate body mass index: Weight(kg)/(height[m])2

  3. Waist Circumference [ Time Frame: 12 months ]
    Waist Circumference measured in cm
