Applied Nutrition, ICMR–NIN** *Nutrition, Metabolic Health & Diet, 150.fit* Prediabetes is not a verdict that diabetes is inevitable. It is an early metabolic warning — and, importantly, a stage where changes in **diet, physical activity, body composition and other lifestyle factors** can meaningfully reduce the risk of progression to type 2 diabetes. This matters particularly in India. The ICMR-INDIAB study estimated that approximately **136 million Indians are living with prediabetes**, alongside more than 100 million with diabetes. The good news is that structured lifestyle intervention works. Indian and international diabetes-prevention trials have consistently shown that changes in food, movement and weight management can reduce progression to type 2 diabetes. The goal is not to find one “diabetes food” or remove every carbohydrate from your plate. The goal is to improve the **quality, quantity and distribution of carbohydrates**, while adding enough protein, fibre and movement to improve insulin sensitivity. --- ## What Is Prediabetes? Prediabetes is a state in which blood glucose is **higher than normal but below the diagnostic range for diabetes**. ### Common Diagnostic Ranges | **Test** | **Normal** | **Prediabetes** | **Diabetes** | | ---------------------- | ---------- | --------------- | ------------ | | Fasting plasma glucose | <100 mg/dL | 100–125 mg/dL | ≥126 mg/dL | | 2-hour OGTT | <140 mg/dL | 140–199 mg/dL | ≥200 mg/dL | | HbA1c | <5.7% | 5.7–6.4% | ≥6.5% | One important point: these tests do not always agree. A person may have normal fasting glucose but high post-meal glucose, and HbA1c can sometimes be influenced by conditions such as iron-deficiency anaemia or haemoglobin disorders. This is why prediabetes should be interpreted as part of a broader metabolic assessment rather than from one number alone. --- # Why Prediabetes Can Look Different in Indians South Asians tend to develop metabolic disease at a **younger age and lower BMI** than many Western populations. Common features include: - Higher visceral fat at a given BMI - Greater tendency toward fatty liver - Lower skeletal muscle mass - Earlier beta-cell dysfunction - Higher triglycerides and lower HDL - Greater metabolic risk despite appearing relatively lean This is sometimes described as the **“thin-fat” phenotype**. That means someone does not have to look visibly overweight to have meaningful insulin resistance or prediabetes. --- # What Causes Blood Sugar to Rise in Prediabetes? Understanding the underlying mechanisms makes the dietary advice much easier to follow. ## 1\. Rapidly Digested Carbohydrates Highly refined carbohydrates are digested quickly, causing a faster rise in blood glucose. The pancreas then has to release more insulin to manage that glucose. Over time, repeated high glucose and insulin demand can become harder to manage when insulin resistance is already present. Adding **fibre, protein, healthy fats and less-refined carbohydrate** generally slows digestion and changes the post-meal glucose response. --- ## 2\. Visceral and Liver Fat When excess fat accumulates around the organs or within the liver and muscle, it can interfere with normal insulin signalling. This is one reason even modest weight loss can improve glucose regulation significantly in people carrying excess visceral or liver fat. --- ## 3\. Meal Order and Gut Hormones The order in which food is eaten may influence the glucose response. Small studies suggest that eating **vegetables and protein before carbohydrate** can reduce post-meal glucose compared with eating carbohydrate first. This is useful as a low-risk addition to a good diet, but it should not be treated as a substitute for overall food quality. --- ## 4\. Fibre and the Gut Microbiome Fibre is fermented by gut bacteria into compounds such as short-chain fatty acids, which are involved in gut-barrier function, metabolic signalling and inflammation. Human studies consistently support higher fibre intake for better metabolic health. However, claims that one particular probiotic or microbiome intervention can prevent diabetes are not established. --- # Can Prediabetes Be Reversed? A better way to frame this is: ### **Can blood glucose return to the normal range and can the risk of developing diabetes be reduced?** For many people, yes. In the **Indian Diabetes Prevention Programme**, lifestyle intervention reduced the relative risk of progression to diabetes by approximately **28.5%**. In the US Diabetes Prevention Program, intensive lifestyle intervention targeting weight loss and physical activity reduced diabetes incidence by **58%**. Some people also return to normal glucose levels. But this does not mean prediabetes has been “permanently cured.” The metabolic risk can return if lifestyle habits and body composition worsen again. --- # The Best Indian Diet for Prediabetes There is no single perfect prediabetes diet. A practical Indian framework is: ### **½ plate vegetables** ### **¼ plate protein** ### **¼ plate carbohydrate** For example, if your current meal is: **3 rotis + ½ katori dal + a small sabzi** a better balance may look like: **2 rotis + 1–1.5 katori dal + a larger serving of sabzi + curd or salad**. The goal is not to remove carbohydrates. It is to improve their **quality, portion and context**. --- # Carbohydrates: What to Choose More Often Choose less-refined carbohydrate sources more often. ### Better options include: - Whole millets such as bajra, jowar, ragi and foxtail millet - Hand-pounded, red, black or unpolished rice - Brown rice - Whole wheat atta - Besan - Barley - Steel-cut or rolled oats - Whole pulses and legumes - Rajma - Chana - Lobia - Whole moong - Horse gram Whole pulses and grains provide more fibre and generally produce a more favourable metabolic response than highly refined versions. --- # Does Rice Need to Be Avoided? No. Rice itself does not need to be banned. The problem is usually: **portion + processing + what it is eaten with** A large portion of polished white rice eaten with very little dal or vegetables is very different metabolically from a moderate portion paired with: - Dal - Vegetables - Curd - Protein So instead of asking: **“Can I eat rice?”** ask: **“How much am I eating, what type am I eating, and what is sitting beside it?”** --- # Are Millets Better for Prediabetes? Millets can be a useful substitute for refined grains. Studies suggest millet-based diets may improve post-meal glucose responses and, in some studies, fasting glucose and HbA1c. But millets are **not a treatment by themselves**. Processing matters too. A whole millet grain and a finely milled millet flour do not behave identically. Think of millets as a **higher-fibre grain option**, not a “diabetes cure.” --- # Protein: Include It at Every Meal Protein is often under-supplied in Indian diets. It supports: - Satiety - Muscle preservation - Glucose disposal - More stable post-meal responses The source draft suggests making sure there is a **visible protein source at every meal**. ## Vegetarian Protein Sources - Dal - Rajma - Chana - Soya chunks - Tofu - Paneer - Curd - Milk - Sprouts - Peanuts - Nuts and seeds ## Non-Vegetarian Protein Sources - Eggs - Fish - Chicken - Lean meat A breakfast made only of poha or plain idli is mostly carbohydrate. Adding **sambar, curd, eggs, paneer, tofu or peanuts** changes the meal substantially. --- # Fibre: Aim for a High-Fibre Diet The source recommends approximately **25–35 g of fibre per day**, built up gradually. Good sources include: - Whole pulses - Vegetables - Guava - Apple - Pear - Flaxseed - Chia - Methi seeds - Psyllium husk - Whole grains If your current fibre intake is low, increase it slowly and maintain adequate fluid intake to reduce bloating. --- # Healthy Fats: Focus on Quality Fat does not need to be eliminated. Prioritise: - Mustard oil - Groundnut oil - Sesame oil - Nuts - Seeds - Oily fish - Flaxseed - Chia - Walnuts Limit: - Repeatedly reheated frying oil - Vanaspati - Excess deep-fried food - Large amounts of highly processed foods Ghee can be used in modest culinary amounts, but it should not be viewed as a treatment for insulin resistance. --- # Dairy and Fermented Foods Unsweetened curd and buttermilk can be practical additions to a prediabetes diet. They can add: - Protein - Calcium - Satiety - Fermented foods Choose **unsweetened** versions. Commercial probiotic supplements are not necessary for everyone, and current evidence does not support treating them as a primary prediabetes intervention. --- # Spices and Traditional Foods: What Actually Helps? Indian diets include several traditional foods often promoted for blood sugar. The evidence is mixed. ## Fenugreek Fenugreek has some supportive research, including a small Indian trial in people with prediabetes. Culinary use is reasonable. Therapeutic doses should be discussed with a clinician, particularly if you take glucose-lowering medication. ## Cinnamon Some studies suggest small improvements in fasting glucose, but results are inconsistent. It should not replace established dietary or medical management. ## Turmeric / Curcumin Curcumin has anti-inflammatory effects, but evidence for preventing diabetes remains emerging rather than definitive. ## Karela, Jamun and Amla These foods can absolutely be part of a healthy diet. But they should not be treated as a replacement for overall nutrition, movement or prescribed medication. --- # Foods to Limit in Prediabetes This does not mean these foods can never be eaten. The goal is to reduce their **frequency and portion size**. ## Limit More Often - Sugar-sweetened beverages - Colas - Packaged juices - Sweetened lassi - Energy drinks - Fruit juice - Sweetened tea and coffee - Maida-based breads - Biscuits - Rusk - Naan - Samosa - Kachori - Bhature - Packaged namkeen - Mithai - Desserts - Instant noodles - Sugary breakfast cereals - Flavoured yoghurt - Deep-fried foods - Large portions of polished white rice The source article particularly highlights sugary beverages, fruit juice and refined flour products as foods worth reducing. --- # Best Indian Breakfasts for Prediabetes Breakfast should ideally combine **protein + fibre + controlled carbohydrate**. Good options include: ### Option 1 **2 vegetable besan chillas + mint chutney + curd** ### Option 2 **Moong dal cheela + paneer bhurji** ### Option 3 **Millet or ragi idli + dal-rich sambar + peanut chutney** ### Option 4 **Vegetable oats + peanuts + eggs** ### Option 5 **Poha with extra vegetables + peanuts + sprouts + curd** ### Option 6 **Overnight oats + curd + chia + guava** The common issue is not the breakfast dish itself. It is eating a **carbohydrate-only breakfast** without enough protein or fibre. --- # Indian Lunch Ideas for Prediabetes ### Option 1 **2 phulkas + 1–1.5 katori dal or rajma + sabzi + salad + curd** ### Option 2 **1 katori unpolished rice + sambar + vegetable poriyal + curd** ### Option 3 **Jowar bhakri + baingan bharta + chana salad** ### Option 4 **Fish curry + small portion rice + steamed vegetables** --- # Indian Dinner Ideas for Prediabetes Aim for a balanced dinner rather than simply avoiding carbohydrates. Examples: ### Option 1 **Vegetable-dal khichdi + curd + salad** ### Option 2 **Grilled chicken or paneer tikka + vegetables + 1 roti** ### Option 3 **Millet upma + vegetables + dal** ### Option 4 **Soup + besan chilla + salad** The source suggests keeping dinner lighter and ideally finishing it around **2–3 hours before sleep**. --- # Healthy Snack Options Instead of biscuits, namkeen or sweetened drinks, consider: - Roasted chana - Sprouts chaat - Nuts - Boiled egg - Buttermilk - Curd with seeds - Guava - Apple - Cucumber and carrot sticks - Hung-curd dip --- # Two Simple Habits That Can Improve Post-Meal Glucose ## 1\. Eat Vegetables and Protein First Where practical: **Vegetables → Protein → Carbohydrate** Small studies suggest that meal sequencing can reduce the post-meal glucose rise. Do not overcomplicate this. It is simply a useful habit. ## 2\. Walk for 10–15 Minutes After Meals A short walk after meals can reduce post-meal glucose excursions. This is one of the simplest low-cost interventions available. You do not need a gym. Just move. --- # Exercise for Prediabetes Diet is only part of the strategy. Aim for approximately: ### **150 minutes of moderate aerobic activity per week** plus ### **Resistance training 2–3 times per week** Resistance training is especially relevant for South Asians because lower skeletal muscle mass can reduce the body's capacity to dispose of glucose. --- # Weight Loss and Prediabetes If you have excess body fat, particularly abdominal fat, modest weight loss can substantially improve insulin sensitivity. A commonly used target is approximately: ### **5–7% of body weight** This does not mean everyone with prediabetes needs aggressive weight loss. For older adults, lean people and those at risk of muscle loss, preserving muscle may be just as important. --- # Sleep, Stress and Blood Sugar Metabolic health is not determined by food alone. ## Sleep Short or irregular sleep can impair insulin sensitivity. If you snore heavily and experience daytime sleepiness, obstructive sleep apnoea may also be worth discussing with your doctor. ## Stress Chronic stress can influence glucose metabolism through stress hormones such as cortisol. Stress management is not a replacement for nutrition or medical treatment, but it is part of the bigger picture. --- # What Should You Monitor? Discuss appropriate monitoring with your clinician. Depending on your risk profile, this may include: - HbA1c - Fasting glucose - Post-meal glucose - OGTT - Lipid profile - Triglycerides - Blood pressure - Waist circumference - Liver enzymes - Fatty liver assessment - Vitamin B12 - Vitamin D where indicated The source notes that continuous glucose monitors can sometimes be educational, but evidence for improving long-term outcomes in prediabetes remains limited. --- # Common Prediabetes Myths ## Myth: Rice causes diabetes **Fact:** No single grain causes diabetes. Portion, processing, fibre, protein and what else is on the plate all matter. ## Myth: Wheat is always better than rice **Fact:** Refined wheat products such as maida, biscuits and naan can also produce significant glucose responses. ## Myth: Fruit should be avoided **Fact:** Whole fruit can be part of a balanced prediabetes diet. Prefer whole fruit over juice. ## Myth: Honey and jaggery are healthier sugars **Fact:** They may contain trace nutrients, but metabolically they still behave largely as sugars. ## Myth: Prediabetes can be permanently reversed with a 3-month diet **Fact:** Some people return to normal glucose levels, but maintaining that improvement requires sustained habits and ongoing monitoring. --- # Do Supplements Help Prediabetes? For most people, **food, exercise and weight management matter more than supplements**. The source reviews several common supplements: ### Vitamin D Correct deficiency where present, but taking vitamin D specifically to prevent diabetes is not strongly supported. ### Vitamin B12 Particularly relevant for vegetarians and people using metformin long term. ### Omega-3 Useful for general nutrition in appropriate situations, but not a primary glucose-lowering treatment. ### Berberine Some studies suggest glucose-lowering effects, but research quality varies and it can interact with medications. ### Psyllium Can be useful when dietary fibre intake is difficult to achieve. Do not self-prescribe high-dose supplements alongside medication without discussing them with your healthcare provider. --- # Who Needs Extra Caution? Dietary changes should be individualised if you are: - Pregnant or breastfeeding - Living with chronic kidney disease - Living with advanced liver disease - Taking insulin or glucose-lowering medications - An older adult at risk of frailty - A child or adolescent - Following religious fasting while on medication - Living with significant food allergies or intolerances - Living with or recovering from an eating disorder The source gives detailed cautions for these groups. --- Prediabetes should not be treated as a reason to panic. It should be treated as a reason to act. You do not need to stop eating Indian food. You do not need to eliminate rice, roti, fruit or every carbohydrate. Instead, focus on changing the **structure of your plate**: ### **More vegetables** ### **More protein** ### **More fibre** ### **Better-quality carbohydrates** ### **Smaller portions of refined foods** ### **Regular movement** The goal is not to create a perfect diet for three months. It is to build a way of eating and living that improves insulin sensitivity and remains sustainable for years. --- ## References & Further Reading 1.
