How to Prevent Diabetes: What Works for Indians

India is often called the diabetes capital of the world, with well over a hundred million people living with diabetes or prediabetes. Indians develop type 2 diabetes about a decade earlier than people in many Western countries, at lower body weights, and with more serious complications.

But this is not destiny. Type 2 diabetes is one of the most preventable chronic diseases. Large studies, including Indian trials, show that lifestyle change can cut the risk of developing diabetes by more than half in people at high risk.

Why Indians Are at Higher Risk

• Genetic susceptibility: South Asians tend to have more insulin resistance and store fat around the abdomen.
• The "thin-fat" phenotype: a normal-looking weight can hide high body fat and low muscle.
• Diet: heavy reliance on white rice, refined flour, sugar, and fried snacks.
• Sedentary lifestyle: long desk hours and limited exercise.
• Stress and poor sleep: both raise blood sugar.
• Family history: having a parent with diabetes significantly raises your risk.
• Urbanisation: changes in food and activity patterns over the last few decades.
• Early-life factors: low birth weight followed by weight gain in adulthood.

Understanding Prediabetes

Prediabetes means blood sugar is higher than normal but not yet in the diabetes range. It is the window of opportunity.

| Test | Normal | Prediabetes | Diabetes | |---|---|---|---| | Fasting glucose | Below 100 mg/dL | 100 to 125 | 126 or above | | HbA1c | Below 5.7% | 5.7 to 6.4% | 6.5% or above | | 2-hour post-meal / OGTT | Below 140 | 140 to 199 | 200 or above |

Prediabetes often has no symptoms. Without action, a large proportion of people progress to diabetes within a few years. With action, many return to normal.

Who Should Be Screened?

• All adults from age 30 (earlier for Indians with risk factors)
• Anyone with a waist above 90 cm (men) or 80 cm (women)
• BMI of 23 or more
• Family history of diabetes
• High blood pressure or abnormal cholesterol
• PCOS or a history of gestational diabetes
• Fatty liver
• Dark, velvety skin patches at the neck or armpits (acanthosis nigricans)

Test at least once every one to three years, or yearly if you are at higher risk.

Seven Steps to Prevent Diabetes

1. Lose a modest amount of weight

Losing 5 to 7 percent of body weight (for example, 4 to 5 kg in an 80 kg person) cuts diabetes risk dramatically. Focus on reducing belly fat.

2. Rework your plate

• Reduce refined carbohydrates: swap white rice, maida, white bread, and sugary cereals for millets (ragi, jowar, bajra), oats, whole wheat, brown or parboiled rice, and smaller portions.
• Add protein to each meal: dal, chana, rajma, curd, paneer, eggs, fish, chicken, sprouts, and soy slow sugar absorption.
• Eat plenty of vegetables: fill half your plate. Fibre blunts blood sugar spikes.
• Eat vegetables and protein first, then carbohydrates. This simple order can lower the post-meal spike.
• Cut sugar-sweetened drinks and sweets: cold drinks, packaged juices, sweetened chai, mithai, and desserts.
• Choose whole fruit over juice. Fruit is fine in sensible portions; juice is concentrated sugar without fibre.
• Limit fried and packaged foods, which add calories and unhealthy fats.
• Use healthy fats: nuts, seeds, mustard oil, groundnut oil, and fish, in moderation.
• Mind the portion of rice and roti. Many people eat far more starch than they realise.

3. Move every day

• Aim for at least 150 minutes of moderate exercise per week, such as brisk walking, cycling, swimming, or dancing.
• Add strength training two to three times a week. Muscle absorbs glucose and improves insulin sensitivity. This is especially important for Indians, who tend to have lower muscle mass.
• Walk for 10 to 15 minutes after meals. It reduces post-meal blood sugar noticeably.
• Break up sitting time: stand and move for a few minutes every hour.

4. Sleep well

Aim for seven to eight hours. Short or poor sleep increases insulin resistance and appetite. If you snore loudly and feel exhausted by day, ask about sleep apnoea, which is closely linked to diabetes.

5. Manage stress

Chronic stress raises cortisol and blood sugar. Regular exercise, yoga, breathing exercises, time with friends, and hobbies help.

6. Avoid tobacco and limit alcohol

Smoking increases diabetes risk and complications. Heavy drinking harms the pancreas and liver and adds calories.

7. Get checked regularly

Know your numbers. Early detection of prediabetes lets you act before damage occurs. If you have prediabetes, repeat testing at least yearly, and sometimes every six months.

A Sample Diabetes-Prevention Day

• On waking: a glass of water; a handful of soaked almonds or walnuts
• Breakfast: vegetable besan chilla, moong dal cheela, or vegetable poha with peanuts, with a bowl of curd; or eggs with whole-wheat toast and vegetables
• Mid-morning: a fruit, or buttermilk
• Lunch: one or two rotis (multigrain), dal, a large serving of green vegetables, salad, curd
• Evening: roasted chana, sprouts chaat, or nuts; tea with little or no sugar
• Dinner: a light meal, such as grilled fish, paneer, or chicken with vegetables, or vegetable dal khichdi, eaten two to three hours before bed
• After meals: a 10-minute walk

Medicines and Prevention

For some high-risk people with prediabetes, especially if lifestyle changes are not enough, doctors may consider medicines such as metformin. This is decided individually and works best alongside lifestyle changes, not instead of them.

Myths About Diabetes

"Eating sugar directly causes diabetes." Sugar is not the only cause, but excess calories, sugary drinks, and weight gain strongly raise risk.

"I'm thin, so I can't get diabetes." Indians can develop diabetes at a normal weight.

"Diabetes is only genetic." Genes load the gun; lifestyle often pulls the trigger.

"Prediabetes is not a big deal." It is a warning and also raises heart disease risk.

"Bitter gourd or herbal powders can prevent it." No supplement replaces diet, exercise, and medical advice.

Warning Signs to Watch For

Excessive thirst, frequent urination, unexplained weight loss, constant hunger, blurred vision, slow-healing wounds, frequent infections, tingling in the feet, and persistent fatigue. If you notice these, get tested promptly.
