The investigators will examine how much the weight loss improves the metabolic abnormalities that precede type 2 diabetes (T2D), and in reversing the pre-clinical/subtle clinical abnormalities of the liver and heart that precede liver and cardiovascular disease (CVD).\n\nThis study will compare the effects of a safe and effective 12-month weight management intervention, initially using a low-calorie, liquid replacement diet for 12 weeks, followed by a weight maintenance phase. The investigators will examine how much the weight loss improves the metabolic and neuropathic abnormalities that precede and accompany type 2 diabetes (T2D), and in reversing the pre-clinical/subtle clinical abnormalities of the liver and heart that precede liver and cardiovascular disease. In an additional optional sub-study, the investigators will additionally assess how the weight loss impacts upon appetite regulation within the brain with functional MRI (fMRI).', 'detailedDescription': 'Prediabetes affects up to 35% of the population. It is defined as an intermediate metabolic state of glucose dysregulation between normoglycaemia and type 2 diabetes (T2D). Prediabetic individuals have 3-12 times higher annual incidence of type 2 diabetes than the general population. Further, these individuals have a considerable increased risk of cardiovascular disease (CVD), (myocardial infarction, stroke, CV death) and even in the absence of coronary artery disease, an increased risk of heart failure. Individuals with prediabetes manifest the same clustering of cardiovascular risk factors (dysglycaemia, dyslipidaemia, hypertension, obesity, physical inactivity, insulin resistance, pro-coagulant state, endothelial dysfunction, inflammation) that confer the high risk for macrovascular complications in type 2 diabetes. For example, 37% and 51% of individuals with prediabetes have hypertension and dyslipidaemia.\n\nResults of large randomised control trials focusing on diabetes management have shown improvements in cardiovascular and renal outcomes and treatments for patients with established type 2 diabetes. Studies examining cardiovascular and renal burdens in patients with prediabetes have demonstrated that the same therapeutic benefits have not been observed in adults with prediabetes. This study focuses on a younger age group considering the aggressive phenotype of young-onset type 2 diabetes as it provides the opportunity to address and effectively manage the associated cardio-metabolic risk factors, prevent progression from prediabetes to type 2 diabetes and reduce the burden of cardiovascular disease, heart failure and liver-related burden.\n\nLiver fat predicts both cardiovascular disease and type 2 diabetes independent of obesity. NAFLD is a growing clinical problem which has become the most prevalent chronic liver disease in Western society. It can be associated with isolated hepatic triglyceride accumulation (steatosis), through steatosis plus hepatocellular damage with inflammation and fibrosis (non-alcoholic steatohepatitis (NASH), which may ultimately progress to liver fibrosis/cirrhosis and hepatocellular carcinoma.\n\nNon-Alcoholic Fatty Liver Disease (NAFLD) is considered the hepatic manifestation of the metabolic syndrome and is commonly associated with insulin-resistant states including obesity, a higher prevalence of prediabetes and type 2 diabetes (T2D).\n\nNAFLD has a bi-directional relationship with prediabetes and T2D being a risk factor for Non-Alcoholic Fatty Liver Disease but conversely, individuals with prediabetes and type 2 diabetes have significantly increased liver fat versus non-diabetic control subjects with a higher risk of NAFLD than Body Mass Index (BMI) -matched non-diabetic controls.\n\nNAFLD is associated with a metabolic phenotype similar to that observed in T2D: hepatic and peripheral insulin resistance with reduced skeletal muscle glucose uptake and increased non-esterified fatty acid (NEFA) release from adipose tissue lipolysis. Once liver fat accumulates in the liver, insulin is unable to inhibit glucose and very-low-density lipoprotein (VLDL) production resulting in overproduction of glucose and very-low-density lipoprotein (VLDL) particles leading to hypertriglyceridaemia and low high-density lipoprotein (HDL)-cholesterol concentrations.\n\nNAFLD is associated with an increased risk of cardiovascular disease with CVD now representing the leading cause of death in NAFLD. While it remains contentious whether the increased risk of CVD in NAFLD is explained by the combination of common risk factors shared by both NAFLD and CVD, most epidemiological studies evaluating CVD risk in NAFLD suggest the risk occurs independently of associated risk factors. These studies have relied upon biochemical and imaging surrogate markers of NAFLD (e.g. serum liver enzymes, abdominal ultrasound). Using more detailed assessment of NAFLD e.g. assessment of fibrosis with fibrosis panels, with Magnetic Resonance Imaging (MRI) or even biopsy-based.\n\nClinical studies have shown that sustained moderate weight loss of around 5-10%, achieved through lifestyle intervention lowers blood pressure, improves glucose control, prevents diabetes, and improves dyslipidaemia, as well as improving haemostatic and fibrinolytic factors. The effects of weight reduction on progression to T2D has been studied in pre-diabetes in the Diabetes Prevention Programme study (US) study. A 1 kg of weight loss is associated with a 16% reduction in the progression of pre-diabetes to T2D.\n\nMetabolic surgery is associated with remission of T2D. There is overwhelming evidence that LCDs have a useful role in T2D resulting in substantial weight loss (mean difference in weight vs. controls after 3 months was 7.38 kg (CI: 16.2, 1.5) with high levels of adherence. They can potentially cause profound weight loss of 15-20% of body weight in severe and medically complicated obesity. The weight loss is associated with significant reductions in hepatic and pancreatic fat with associated improvements in insulin sensitivity and pancreatic ß-cell function resulting in remission of T2D in many cases. This dramatic dietary intervention, initially believed to be unmanageable and difficult to maintain, has been demonstrated to be implementable and highly efficacious even when delivered through primary care settings.\n\nIn one primary care study, using LCD in T2D patients recorded a weight loss of 15kg or more in 24% of patients after 12 months. It is unsurprising that 46% of the participants achieved remission of their T2D. LCD produces bariatric type weight loss and improves glycaemic control in diabetes and results in remission of T2D in the majority of patients, however the impact on complications, remains to be determined particularly in obese people without diabetes. One non-pharmacological strategy to improve cardio-metabolic health in obesity, pre-diabetes and type 2 diabetes mellitus (T2DM) includes the application of a low-calorie diet (LCD), utilising reduced daily energy intake (\\<800kcal).\n\nTo this extent, the purpose of this study is to examine the impact of intensive weight management on metabolic, liver and cardiac health, measures on neuropathy and on appetite regulation. The investigators will study younger (\\<55y) obese people with pre-diabetes and/or metabolic syndrome who exhibit early or pre-clinical evidence of metabolic and cardiovascular complications. The investigators will investigate the effects of a low-calorie diet (LCD) as one of the most effective and least invasive mechanism by which these various factors can be improved.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '55 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* The investigators shall recruit participants with the following characteristics:\n\n * Men and women\n * aged 18-55 years\\*,\n * BMI 30-40 kg/m2 , BMI\\>27 kg/m2 for Chinese/South Asians\n * Any one of the following three metabolic criteria:\n\n 1. a diagnosis of prediabetes (HbA1c 42-47 mmol/mol), OR\n 2.
