Background and study aims
Type 2 diabetes is a condition that causes the level of sugar (glucose) in the blood to become too high. It is becoming more common and adults are getting it at younger ages. Many young adults (aged between 18-40 years) are now being diagnosed with the disease. This is worrying because heart, kidney and physical function problems related to diabetes can therefore happen at an early age. Past studies have shown that low-energy diets lead to over half of people reversing their type 2 diabetes. This means that blood sugar levels return to normal. This is called ‘reversing diabetes.’ A low-energy diet means eating a lot less than normal for a short period of time. Once people have lost enough weight, they can start to eat regular food again. Structured exercise, such as walking and simple weight training activities, can also improve blood sugar levels as well as heart function. The effects of combining the two approaches - a low-energy diet and structured exercise - have not been studied together in terms of reversing diabetes. The main goal of this study is to see whether combining structured exercise and a low-calorie diet can reverse diabetes. The study will also look at whether heart health is improved over 24 weeks.

Who can participate?
Adults who have type 2 diabetes and are between 18 and 45 years old (inclusive)

What does the study involve?
Participants are randomly allocated to one of two groups. The control group will continue to receive standard care. The intervention group will be prescribed a low-energy diet with total meal replacement for the first 2 weeks, followed by partial meal replacement from weeks 3-12. This will be followed by individualised food reintroduction (weeks 13-24). During weeks 3-12, this will be combined with supervised aerobic and resistance exercise, and a transition to unsupervised home-based exercise will be introduced in weeks 13-24. The intervention group will be taken off their glucose-lowering medication and antihypertensive medication by a study physician at the start of the intervention. However, ACE inhibitors or angiotensin receptor blockers will not be discontinued in the context of albuminuria (where the protein albumin is abnormally present in the urine). Following the 24-week intervention period, the control group will be offered the meal replacement component of the low-energy diet complemented by a 4-week food reintroduction period with support from the study dietitians and physicians.

What are the possible benefits and risks of participating?
During the study participants will receive close monitoring of their diabetes. The study will also provide detailed results of their heart function, body fat and exercise levels. The researchers will be happy to review the results with them after the study is completed. The diet used in this study can completely reverse diabetes. This happens in many patients who manage to stick to it. Patients often feel much healthier and this tends to occur quickly. This is usually within the first week. Their medication is likely to be reduced or stopped altogether. However, not everyone reverses their diabetes. Whether they are able to maintain this after the study depends on how their body responds over the longer term and how well they are able to continue the new eating habits. Exercise training improves fitness. It also helps to control blood sugars. Exercise training also lowers blood pressure, the amount of harmful fat in the blood and may improve the blood supply to the heart. These changes may have long-term benefits in preventing heart disease. The study will hopefully improve the understanding of how to reverse diabetes. It will also show how diabetes affects the heart. The results could lead to improved medical treatments and programmes in the future.
In past studies, the low-energy diet has led to symptoms like constipation, dizziness, fatigue, thirst, and/or headache in some people taking part. These tend to get better with fibre-based laxatives and time. It is also important to drink as much water as needed when on the diet. With exercise, there are risks of injury to joints, bones, and muscles. The supervisor will work with the participants to exercise as safely as possible. Exercise may also lead to fatigue and dizziness in some cases. Again, over time these should improve. Stopping diabetes and blood pressure medications at the beginning of the diet and exercise programme may lead to blood sugars and blood pressure going up. The researchers will monitor this to see if they need to restart medications. Diet and exercise may lead to low blood sugar and low blood pressure, but this is unlikely when not taking medication.

Health condition(s) or problem(s) studiedType 2 diabetes mellitus (T2DM)
InterventionThis trial is a 24-week randomised control trial with two arms. Randomisation (at the individual level, stratified by country) will occur once all baseline measures are completed and individuals are confirmed to be eligible. Individuals deemed ineligible following baseline evaluation will not be randomised. A permuted block randomisation will be performed and an independent statistician will develop a computer-assisted random sequence within the block. When the investigator is not blinded, and the block size is fixed, the allocation is predictable. To preserve allocation concealment, the block size will be varied (e.g., 2, 4).

1. The control group - participants randomly allocated to this group will continue to receive standard care.

2. The intervention group will be prescribed a low energy diet with total meal replacement for the first 2 weeks, followed by partial meal replacement from weeks 3-12. This will be followed by individualised food reintroduction (weeks 13-24). During weeks 3-12, this will be combined with supervised aerobic and resistance exercise, and a transition to unsupervised home-based exercise will be introduced in weeks 13-24. Individuals randomly assigned to the intervention group will be taken off their glucose-lowering medication and antihypertensive medication by a study physician at the onset of the intervention. However, ACE inhibitors or angiotensin receptor blockers will not be discontinued in the context of albuminuria.

Following the 24-week intervention period, participants enrolled into the control group will be offered the meal replacement component of the low energy diet complemented by a 4-week food reintroduction period with support from the study dietitians and physicians.

Participants will receive the same level of clinical and dietetic management as the intervention arm, but captured data will not form part of the study outcomes.
