Plain language summary
Various studies have shown that intermittent low-calorie diets are effective in reducing weight and improving glycaemic control. In this randomized controlled trial, two intermittent very-low calorie diets (2 days per week and 4 days per week) were evaluated against a control group with respect to achieving diabetes remission, improving glycemic control, metabolic parameters, and quality of life in Type 2 diabetic patients. There was a significant reduction in HbA1c and insulin resistance in the 2 days/week and 4 days/week intermittent very-low calorie groups at week 20. Both the intervention groups achieved diabetes remission with 29% of participants not requiring glucose-lowering medications at week 20. Both intervention groups also showed a significant reduction in serum triglycerides, body weight, body mass index, and fat mass. Aspartate transaminase and alanine aminotransferase levels, as well as blood pressure, decreased significantly with a 4 day/week intermittent low-calorie diet. Both intervention groups experienced improved quality of life at week 10 and the interventions were generally well tolerated. To generalise the results, longer-term, robust studies are required. These results can help healthcare providers understand the clinical relevance of intermittent very-low calorie diets in managing Type 2 diabetes and obesity.
Abstract
AIMS/INTRODUCTION Very few studies assess the effectiveness of different protocols of intermittent very-low calorie diet (VLCD) in patients with diabetes. This study was designed to compare the effects of 2 days/week and 4 days/week of intermittent VLCD on glycemic control, diabetes remission, metabolic parameters and quality of life in patients with type 2 diabetes and obesity. MATERIALS AND METHODS Participants with obesity and type 2 diabetes were recruited and randomly assigned to three groups, consisting of control, 2 days/week and 4 days/week of intermittent VLCD. In the intermittent VLCD groups, participants received a 600-kcal diet per day on restricted days and ad libitum food consumption on non-restricted days. Glycemic control, rate of diabetes remission, metabolic parameters and quality of life were evaluated at baseline, weeks 2, 10 and 20. RESULTS A total of 40 participants were enrolled. The mean body mass index was 30.1 ± 5.9 kg/m2 , and the mean glycated hemoglobin was 7.4 ± 1.2%. At week 20, there was an improvement in glycemic control in both intermittent VLCD groups with significant decreases in glycated hemoglobin levels and insulin resistance index throughout the study periods. Diabetes remission without the need for medications was equally found in 29% of participants in both intermittent VLCD groups. Serum triglyceride, bodyweight, body mass index and fat mass were also significantly decreased in both VLCD groups. No serious adverse events were encountered. CONCLUSION Intermittent VLCD was highly effective in achieving optimal glycemic control. The effects of 2 days/week and 4 days/week of intermittent VLCD on diabetes remission were relatively similar.

Plain language summary
Type 2 Diabetes is considered a lifelong condition, but calorie restriction or weight loss can lead to complete remission. Patients newly diagnosed with Type 2 Diabetic may benefit from behavioural change over the long run. When Type 2 Diabetes is diagnosed early in the disease trajectory, it may increase the patient's motivation and make them more receptive to weight-loss interventions. This prospective cohort study included 865 newly diagnosed Type 2 diabetic patients from the ADDICTION Cambridge Trial, a pragmatic, parallel-group cluster randomised controlled trial. The study assessed the relationship between behaviour change and weight loss and the prospect of type 2 diabetes remission in the first year, following four years and after five years without intense dietary or lifestyle intervention in patients. 30% of the patients achieved diabetes remission at 5-year follow-up, with a significant likelihood of remission among those who achieved ≥ 10% weight loss in the first year of diagnosis. A self-reported change in intake of alcohol units was found to be the only consistent association between behaviour change and remission in this study. The role of behaviour change in the remission of diabetes requires further robust research. This study will help healthcare professionals understand the association between weight loss and remission in diabetic patients.
Abstract
AIM: To quantify the association between behaviour change and weight loss after diagnosis of Type 2 diabetes, and the likelihood of remission of diabetes at 5-year follow-up. METHOD We conducted a prospective cohort study in 867 people with newly diagnosed diabetes aged 40-69 years from the ADDITION-Cambridge trial. Participants were identified via stepwise screening between 2002 and 2006, and underwent assessment of weight change, physical activity (EPAQ2 questionnaire), diet (plasma vitamin C and self-report), and alcohol consumption (self-report) at baseline and 1 year after diagnosis. Remission was examined at 5 years after diabetes diagnosis via HbA1c level. We constructed log binomial regression models to quantify the association between change in behaviour and weight over both the first year after diagnosis and the subsequent 1-5 years, as well as remission at 5-year follow-up. RESULTS Diabetes remission was achieved in 257 participants (30%) at 5-year follow-up. Compared with people who maintained the same weight, those who achieved ≥ 10% weight loss in the first year after diagnosis had a significantly higher likelihood of remission [risk ratio 1.77 (95% CI 1.32 to 2.38; p<0.01)]. In the subsequent 1-5 years, achieving ≥10% weight loss was also associated with remission [risk ratio 2.43 (95% CI 1.78 to 3.31); p<0.01]. CONCLUSION In a population-based sample of adults with screen-detected Type 2 diabetes, weight loss of ≥10% early in the disease trajectory was associated with a doubling of the likelihood of remission at 5 years. This was achieved without intensive lifestyle interventions or extreme calorie restrictions. Greater attention should be paid to enabling people to achieve weight loss following diagnosis of Type 2 diabetes.

Plain language summary
Most individuals with type 2 diabetes are obese with accumulation of fat around the liver and pancreas. Many studies have demonstrated that dietary induced weight loss can improve type 2 diabetes, however none have assessed whether dietary weight loss can sustain type 2 diabetes remission. This 12-month randomised trial of 306 individuals with type 2 diabetes aimed to determine whether weight management led by doctors would achieve long-term remission of type 2 diabetes. The results showed that weight loss of 15kg or more resulted in significantly higher rates of type 2 diabetes remission after 12 months, with 48% of the weight loss group achieving remission compared to 4% of the individuals who were not assigned a weight loss regimen. It was concluded that nearly half of the participants who were on a dietary weight loss programme achieved type 2 diabetes remission and were able to stop their medications. This study could be used by healthcare professionals to understand that type 2 diabetes remission is a possibility with a supervised dietary weight loss programme.
Abstract
BACKGROUND Type 2 diabetes is a chronic disorder that requires lifelong treatment. We aimed to assess whether intensive weight management within routine primary care would achieve remission of type 2 diabetes. METHODS We did this open-label, cluster-randomised trial (DiRECT) at 49 primary care practices in Scotland and the Tyneside region of England. Practices were randomly assigned (1:1), via a computer-generated list, to provide either a weight management programme (intervention) or best-practice care by guidelines (control), with stratification for study site (Tyneside or Scotland) and practice list size (>5700 or ≤5700). Participants, carers, and research assistants who collected outcome data were aware of group allocation; however, allocation was concealed from the study statistician. We recruited individuals aged 20-65 years who had been diagnosed with type 2 diabetes within the past 6 years, had a body-mass index of 27-45 kg/m2, and were not receiving insulin. The intervention comprised withdrawal of antidiabetic and antihypertensive drugs, total diet replacement (825-853 kcal/day formula diet for 3-5 months), stepped food reintroduction (2-8 weeks), and structured support for long-term weight loss maintenance. Co-primary outcomes were weight loss of 15 kg or more, and remission of diabetes, defined as glycated haemoglobin (HbA1c) of less than 6·5% (<48 mmol/mol) after at least 2 months off all antidiabetic medications, from baseline to 12 months. These outcomes were analysed hierarchically. This trial is registered with the ISRCTN registry, number 03267836. FINDINGS Between July 25, 2014, and Aug 5, 2017, we recruited 306 individuals from 49 intervention (n=23) and control (n=26) general practices; 149 participants per group comprised the intention-to-treat population. At 12 months, we recorded weight loss of 15 kg or more in 36 (24%) participants in the intervention group and no participants in the control group (p<0·0001). Diabetes remission was achieved in 68 (46%) participants in the intervention group and six (4%) participants in the control group (odds ratio 19·7, 95% CI 7·8-49·8; p<0·0001). Remission varied with weight loss in the whole study population, with achievement in none of 76 participants who gained weight, six (7%) of 89 participants who maintained 0-5 kg weight loss, 19 (34%) of 56 participants with 5-10 kg loss, 16 (57%) of 28 participants with 10-15 kg loss, and 31 (86%) of 36 participants who lost 15 kg or more. Mean bodyweight fell by 10·0 kg (SD 8·0) in the intervention group and 1·0 kg (3·7) in the control group (adjusted difference -8·8 kg, 95% CI -10·3 to -7·3; p<0·0001). Quality of life, as measured by the EuroQol 5 Dimensions visual analogue scale, improved by 7·2 points (SD 21·3) in the intervention group, and decreased by 2·9 points (15·5) in the control group (adjusted difference 6·4 points, 95% CI 2·5-10·3; p=0·0012). Nine serious adverse events were reported by seven (4%) of 157 participants in the intervention group and two were reported by two (1%) participants in the control group. Two serious adverse events (biliary colic and abdominal pain), occurring in the same participant, were deemed potentially related to the intervention. No serious adverse events led to withdrawal from the study. INTERPRETATION Our findings show that, at 12 months, almost half of participants achieved remission to a non-diabetic state and off antidiabetic drugs. Remission of type 2 diabetes is a practical target for primary care. FUNDING Diabetes UK.
