RESUMEN
Introduction: Hyperinsulinemia in the absence of impaired glucose tolerance and normal HbA1c is considered indicative of pre-diabetes. Very few Indian studies have focused on hyperinsulinemia particularly in young adults. The present study aimed to determine whether hyperinsulinemia may be present despite HbA1c being normal. Methods: This was a cross-sectional study conducted on adolescents and young adults aged 16-25 years living in Mumbai, India. The participants attended various academic institutions and were those who underwent screening as the first step of a clinical trial for studying the efficacy of almond intake in prediabetes. Results: Among this young population (n=1313), 4.2% (n=55) of the participants were found to be prediabetic (ADA criteria) and 19.7% of them had HbA1c levels between 5.7%-6.4%. However, almost, 30.5% had hyperinsulinemia inspite of normal blood glucose levels and normal HbA1c. Among those with HbA1c<5.7 (n=533), 10.5% (n=56) participants had fasting insulin>15 mIU/L and a higher percentage (39.4%, n=260) had stimulated insulin above 80 mIU/L. These participants had higher mean anthropometric markers than those with normal fasting and/or stimulated insulin. Conclusion: Hyperinsulinaemia in the absence of impaired glucose tolerance and normal HbA1c may provide a much earlier indicator of detection for risk of metabolic disease and progression to metabolic syndrome and diabetes mellitus.
RESUMEN
BACKGROUND: Obesity, prediabetes, and type 2 diabetes mellitus (T2DM) pose a triple burden in India. Almost two-thirds of people with diabetes (PWD) in India are found to have suboptimal glycemic, blood pressure, and lipid control. Medical nutrition therapy (MNT) in diabetes has emphasized on the amount and type of carbohydrates for years. However, protein, an important macronutrient in diabetes management, needs to be focused upon, especially in India, where the consumption is found to be lower than the recommendations provided by most guidelines. AIM: An expert committee attempted to review the role of dietary protein in the management of T2DM, arrive at a consensus on the significance of increasing dietary protein for various benefits, and offer practical guidance on ways to improve protein intake among Indians. METHODOLOGY: A total of 10 endocrinologists and diabetologists, one nephrologist, and three registered dietitians representing four zones of India formed the expert committee. An in-depth review of literature in the Indian context was carried out, and the draft document was shared with the expert committee, and their views were incorporated into the same. The expert committee then assembled virtually to deliberate on various aspects of the role of protein in T2DM management. The experts from various specialties gave their valuable inputs and suggestions from their extensive personal clinical experience and research work, which helped to reach a consensus on the role and significance of protein in the management of T2DM and its complications in India. RESULTS: There is abundant evidence that MNT is essential for the prevention and management of T2DM and its complications. Experts agreed that increasing protein intake offers myriad health benefits, namely reducing glycemic variability, improving glycemic control, increasing insulin sensitivity, improvement in lipid profile and immunity, and helping in weight management and preservation of muscle mass in PWD. The expert committee suggested aiming for an increase in protein intake by at least 5-10% of the current intake in lieu of carbohydrates in PWD. Experts also highlighted the need for more data quantifying the unmet protein needs in the Indian PWD, especially among vegetarians. Randomized controlled trials to study the effect of protein in diabetes complications such as cardiovascular disease (CVD) and diabetic kidney disease (DKD) and comorbid conditions such as sarcopenia among the Indian population are also warranted. CONCLUSION: Increasing protein quantity and quality in the diets of Indian PWD could significantly contribute to positive health outcomes. Increased protein intake, preferably through dietary sources to meet the requirements and, when required using diabetes-specific protein supplements (DSPS), is recommended in the prevention and control of T2DM.

Type 2 diabetes (T2DM) is conventionally considered a progressive disorder, with most patients requiring increasingly intensive therapy to control hyperglycemia over time. Recently, there has been a major paradigm shift towards trying to reverse T2DM. Emerging evidence suggests that remission of T2DM is feasible in a subset of patients. Identification and careful selection of candidates for remission are crucial for the success of these programs. Among various dietary strategies, low-calorie diets (LCDs) and low-carbohydrate diets (LCBDs) have been demonstrated as being effective in facilitating remission of T2DM in a targeted population within a clinical setting. Remission with LCBDs may be maintained in the absence of weight loss, however, long-term evidence is limited and remission may not be maintained without long-term carbohydrate restriction, which poses major challenges. In very low-calorie diets (VLCDs), weight loss of 15 kg or greater and maintenance of weight loss is the main driver and predictor of remission. However, most individuals with T2DM were unable to maintain remission beyond 2 years, despite being on VLCDs. More data are required on the long-term sustainability of remission in an ethnically diverse population like Asian Indians with T2DM who have less obesity and hence less weight to lose. Moreover, "re-reversal" or "relapse" of diabetes can occur in a large percentage of individuals who discontinue the dietary restrictions. Hence, regular follow-up by a multi-disciplinary team to ensure sustainability of the lifestyle modification is crucial to the maintenance of remission of T2DM.

BACKGROUND: Worldwide, obesity has nearly tripled since 1975 and has become a major healthcare challenge today. Intermittent fasting (IF) is gaining popularity as a weight loss strategy in recent times. This study aimed to study the role of IF as a modern-day weight-loss strategy in obese adults through a real-world pilot experiment conducted at a nutrition clinic in Mumbai. METHODOLOGY: To understand the effects of IF on weight loss, 32 overweight/obese [body mass index (BMI) ≥23 kg/m2] adults from a nutrition clinic in Mumbai, were assigned consecutively to an IF plan and followed up for 3 months. Their demographic, anthropometric, and dietary assessments were done pre- and post-intervention. Qualitative interviews were done at the end of the study to record the participants' overall well-being, experience, and sustainability of IF. RESULTS: 56% of study participants were males and their mean age was 35.6 ± 8.9 years. 65.6% of participants were able to maintain 14-16 hours of fasting and 53% managed all 7 days of IF. Analysis of post-intervention data showed a significant reduction in mean body weight (88.5 ± 19 to 83.8 ± 17.6 kg), waist circumference (M: 108.2 ± 11.3 to 103.6 ± 4.4 cm, F: 98.9 ± 8.8 to 93.3 ± 3.3 cm), BMI (31.4 ± 5.3 to 29.6 ± 5.1 kg/m2), daily calories (1782 ± 237 to 1388 ± 243 kcal/day), carbohydrate intake (267 ± 18.4 to 164 ± 4.0 g/day), and an increase in protein intake (39 ± 11 to 55 ± 11 g/day). Participants reported positive experiences of practicing IF such as improved fitness, sleep cycle, and adoption of healthy eating habits. CONCLUSION: The study demonstrates that IF could aid in weight loss and adoption of a healthier lifestyle.

BACKGROUND & AIMS: India is facing a triple burden of pre-diabetes, diabetes, and obesity. Unhealthy eating habits and physical inactivity have been linked to the onset and progression of type 2 diabetes mellitus (T2DM). Despite dietary recommendations, individuals consume inadequate amounts or unsuitable type of dietary fiber (DF) which needs correction. An Expert group attempted to review and report on the role and importance of high DF in the management of T2DM and offer practical guidance on high fiber use in daily diet. METHODOLOGY: Twelve diabetologists and two expert dietitians from India were chosen to ensure diversity of the members both in professional interest and cultural background. The authors convened virtually for one group meeting and actively participated in a detailed discussion. Multiple reviews of the draft document followed by focused teleconference calls & email helped to reach consensus on final recommendations between Aug 2021 and Dec 2021. RESULTS: Evidence has shown that medical nutrition therapy (MNT) is a valuable approach and an essential component of T2DM prevention and management. Studies have shown that fiber rich diabetes nutrition (FDN) has multi-systemic health benefits, including, improvement in glycemic control, reduction in glucose spikes, decrease in hyperinsulinemia, improvement in plasma lipid concentrations and weight management in T2DM patients. CONCLUSION: A high fiber diet is vital for people with diabetes and associated conditions. Increasing fiber intake, preferably through food or through dietary supplement, may help. Fiber rich diabetes nutrition (FDN) is recommended in order to prevent and manage T2DM.

Objective: To compare the clinical profile of long-term survivors and nonsurvivors with type 1 diabetes (T1D) in India. Research Design and Methods: This is a retrospective study of 76 individuals with T1D who had survived for at least 40 years ("survivors") and 51 individuals with T1D who had died with shorter duration of diabetes ("non-survivors"), from diabetes clinics in different cities of India. Prevalence of complications in both groups and causes of death of the nonsurvivors were analyzed. Retinopathy was diagnosed by retinal photography; chronic kidney disease (CKD) by urinary albumin excretion (micro-or macroalbuminuria) and estimated glomerular filtration rate; peripheral vascular disease (PVD) by doppler measurement of ankle-brachial pressure index; coronary artery disease (CAD) based on history of myocardial infarction or coronary revascularization, and neuropathy by biothesiometry. Results: Mean glycated hemoglobin (8.4% ± 1.5% vs. 10.7% ± 2.2%, P < 0.001), serum low-density lipoprotein cholesterol (91 ± 29 mg/dL vs. 107 ± 22 mg/dL, P = 0.004), and systolic blood pressure (135 ± 16 mmHg vs. 153 ± 37 mmHg, P = 0.003) were lower, and high-density lipoprotein cholesterol (51 ± 11 mg/dL vs. 43 ± 15 mg/dL, P = 0.002) higher, among survivors compared to nonsurvivors. Diabetic retinopathy, CKD, neuropathy, PVD, and CAD were more frequent among nonsurvivors. CAD [25.5%] and renal failure [23.5%] were the most frequent causes of death. Conclusions: In this first report of long-term survivors with T1D from India, we report that survivors had better glycemic and blood pressure control, more favorable lipid profiles and lower prevalence of complications compared to nonsurvivors. However, there could be other protective factors as well, which merit further studies.

Nutrition is crucial for maintaining normal growth, development, and glycemic control in young people with diabetes (PwD). Undue restrictions cause nutrient deficiencies as well as poor adherence to meal plans. Widespread availability of low-cost, ultra-processed, and hyperpalatable food is further damaging. Most families struggle to find ways to provide nutritious, yet attractive, food with a low glycemic index (GI). India is one of the oldest continuous civilizations with a rich and diverse cultural and culinary heritage. Traditional dietary practices, including the centuries-old 'Thali' (meaning plate) concept, emphasize combinations (grains, lentils, vegetables, dairy, spices, prebiotics and probiotics, and fats) of local, seasonal, and predominantly plant-based ingredients. These practices ensure that all of the necessary food groups are provided and fit well with current evidence-based recommendations, including the International Society for Pediatric and Adolescent Diabetes (ISPAD) 2018 Guidelines. Techniques for the preparation, cooking, and preservation of food further impact the GI and nutrient availability. These practices benefit nutrient density, diet diversity, and palatability and thus improve adherence to meal plans and glycemic control. This narrative review describes the ancient wisdom, food composition, and culinary practices from across India which are still valuable today. These may be of benefit worldwide to improve glycemic control as well as quality of life, especially in PwD.

A large percentage of the Indian population has diabetes or is at risk of pre-diabetes. Almond consumption has shown benefits on cardiometabolic risk factors in adults. This study explored the effect of almond consumption on determinants of metabolic dysfunction-blood glucose, lipids, insulin and selected inflammatory markers in adolescents and young adults aged 16-25 years from Mumbai city. This randomized controlled trial was conducted for a period of 90 days on individuals with impaired levels of fasting glucose levels between 100-125 mg/dL (5.6-6.9 mmol/L) and 2-h post-glucose value 140-199 mg/dL (7.8-11.0 mmol/L) and/or fasting insulin (≥15 mIU/ml)/stimulated insulin (≥80 mIU/ml). Of 1,313 individuals screened, 421 met the inclusion criteria, of which 275 consented to participate and 219 completed the trial. The trial was registered with Clinical Trials Registry India (CTRI) CTRI/2018/02/011927. The almonds group (n = 107) consumed 56 g almonds daily, the control group (n = 112) was provided an iso-caloric cereal-pulse based snack. At baseline and endline, blood glucose, insulin, HbA1c, LDL-c, HDL-c, total and ox-cholesterol, triglycerides, hs-CRP, IL-6, TNF-α, adiponectin, leptin were measured and HOMA-IR and FG:FI ratios were calculated. Dietary intakes were assessed. The anthropometric measurements, biochemical markers as well as macronutrient intakes did not differ significantly between the two groups at baseline. Almond consumption significantly decreased HbA1c, total cholesterol and LDL-c. Stimulated insulin decreased post-intervention in both groups, but the decrease was greater in the almonds group. Fasting glucose was reduced post intervention in the controls with no change in the almonds group. FG:FI ratio decreased in the almonds group. TNF-α and IL-6 decreased in the almonds group, while it increased in the control group. Our results showed that almonds reduced HbA1c, LDL-c and total cholesterol levels in just 12 weeks of consumption in these adolescents and young adults who were at risk for developing diabetes. Almonds can be considered as part of food-based strategies for preventing pre-diabetes. Clinical Trial Registration: ClinicalTrials.gov, identifier: CTRI/2018/02/011927.
RESUMEN
Medical nutrition therapy (MNT) is a vital aspect of management of type 1 diabetes mellitus (T1DM) and should be tailored to ethnic and family traditions and the socioeconomic and educational status of the patient. In this article, we discuss the unique aspects of MNT in children and adolescents with T1DM in the Indian setting, with focus on the challenges faced by patients, dieticians and physicians and how these can be overcome. The authors reviewed the available literature on MNT in T1DM from India and prepared the document based on their vast collective clinical experience in treating patients with T1DM from different regions in India. Indian diets are predominantly carbohydrate-based with high glycemic index (GI) and low protein content. Various methods are available to increase the protein and fiber content and reduce the GI of food in order to limit glycemic excursions. Insulin regimens need to be tailored to the child's school timings, meal schedule, and the availability of a responsible adult to supervise/administer insulin. All patients, irrespective of economic and education background, should be taught the broad principles of healthy eating, balanced diet and carbohydrate counting. There are various barriers to dietary compliance, including joint family system, changing lifestyles, and other factors which need to be addressed. There is a need to customize dietary management according to patient characteristics and needs and develop standardized patient educational material on principles of healthy eating in various regional languages.
