A balanced diet for an Indian adult, as set out in the ICMR-NIN Dietary Guidelines for Indians (2024), takes food from at least 8 to 10 food groups a day, with vegetables and fruit filling half the plate. For about 2,000 kcal, 'My Plate for the Day' gives 250 g cereals and millets, 85 g pulses, 300 ml milk or curd, 400 g vegetables, 100 g fruit, 35 g nuts and seeds and 27 g oil. Salt stays under 5 g, added sugar under 5% of energy, and protein comes from food rather than powders.
What is a balanced diet according to ICMR-NIN?
A balanced diet, in the words of the ICMR-National Institute of Nutrition (NIN) Dietary Guidelines for Indians (2024), is one 'consumed through a wise choice of food items from a variety (diverse) of food groups'. Guideline 1 of the 17 guidelines asks for a combination of whole-grain cereals, pulses and millets, plenty of fresh and locally available vegetables, and foods of animal origin such as milk, eggs and meat, particularly for pregnant and lactating women, children and adolescents. Nutrient-rich choices for older adults are pulses, lean meat, fish and low-fat milk.
The guidelines start from what Indians actually eat. NIN's policy brief on My Plate for the Day reports that National Nutrition Monitoring Bureau surveys found a major segment of the population eating far more cereals than recommended, with more than 10% of calories from ready-to-eat foods such as chips, biscuits, chocolates, sweets and juices, and too little from legumes, milk, nuts, vegetables and fruit. People source nutrients from 'not more than 4 to 5 food groups per day', against a recommended minimum of 8 to 10. The brief records that 31% of urban and 16% of rural adults are overweight or obese, and abdominal obesity affects 53.1% of urban and 18.8% of rural adults, while anaemia and undernutrition persist alongside.
The 17 guidelines cover life stages, food groups, limits on salt, sugar and ultra-processed food, and habits such as activity, safe cooking and reading labels. The sections below pull out the numbers an adult needs for a day's eating.
How much of each food group should an adult eat in a day?
For a 2,000 kcal day, ICMR-NIN's My Plate for the Day gives the raw weights below, reproduced from NIN's policy brief and 2023 poster. Energy need depends on body weight and activity; the proportions of vegetables, fruit and milk stay the same.
| Food group (2,000 kcal) | Raw weight per day | Share of energy | Protein |
|---|---|---|---|
| Cereals including millets | 250 g | 42% (~843 kcal) | ~25 g |
| Pulses (egg, fish or meat can replace part) | 85 g | 14% (~274 kcal) | ~20 g |
| Milk or curd | 300 ml | 11% (~216 kcal) | ~10 g |
| Vegetables including green leafy | 400 g | 9% (~174 kcal) | ~10 g |
| Fruit (fresh, not juice) | 100 g | 3% (~56 kcal) | ~1 g |
| Nuts and seeds | 35 g | 9% (~181 kcal) | ~6 g |
| Fats and oils | 27 g | 12% (~243 kcal) | - |
The footnotes matter: vegetables exclude potato; fresh fruit is preferred over juice; sugar, if taken, is restricted to 25 to 30 g a day with cereals cut to keep calories level. The poster adds that people trying to lose weight may cut cereal, and that the plan is not for any specific medical condition. The ICMR-NIN 2020 brief note puts a sedentary adult's energy need at 2,110 kcal for men and 1,660 kcal for women, so a sedentary woman eats a smaller version of the same plate.
How much salt, sugar and oil is too much?
The limits are 5 g of added salt, sugar under 5% of energy (about 25 g), and 20 to 50 g of visible oil depending on calorie needs. Guideline 11 of the 2024 Dietary Guidelines says 'restrict the intake of added salt (sodium chloride) to a maximum of 5 g per day', use iodised salt, and limit processed foods such as snacks, sauces, ketchup, biscuits, chips, cheese and salted fish. It notes that vegetables and fruit supply potassium, which helps the body excrete sodium. The World Health Organization's salt fact sheet gives the same figure, under 5 g of salt (2,000 mg sodium) a day, and reports that global mean intake in 2021 was 11 g a day.
Guideline 1 states that 'sugar should be less than 5% of the total energy per day for adults'. On 2,000 kcal that is 25 g, matching the My Plate note of 25 to 30 g. WHO's healthy diet fact sheet puts free sugars below 10% of energy, with further benefit below 5%.
For oil, the ICMR-NIN 2020 brief note says visible fat (cooking oil) 'must be limited to 20-50 g (4 to 10 teaspoon full) per person/day', with 'not more than 27 g' for a 2,000 kcal diet. Guideline 7 adds: limit ghee and butter, avoid vanaspati (partially hydrogenated fat, which contains trans fats), and do not reheat oil. WHO caps total fat at 30% of energy, saturated fat at 10% and trans fat at 1%.
How much protein do Indian adults need?
An adult needs 0.83 g of protein per kilogram of body weight per day, the Recommended Dietary Allowance set by the ICMR-NIN 2020 expert group, with an Estimated Average Requirement of 0.66 g/kg. The 2020 brief note gives 54.0 g a day for a 65 kg sedentary man and 45.7 g for a 55 kg sedentary woman, plus 9.5 g in the second trimester of pregnancy, 22.0 g in the third, and 16.9 g in the first six months of breastfeeding. The footnote is the part Indian readers need: 'for people consuming cereal-based diet with low quality protein, the protein requirements are 1 g/kg per day'. A rice-and-roti diet with little dal, milk or egg falls into that category.
Quality is the point of Guideline 8. Combining cereals with pulses in a 3:1 ratio improves the protein quality of a meal, and the 2020 brief note recommends a cereal:legume:milk ratio of 3:1:2.5. On My Plate, cereals, pulses, milk and nuts together deliver about 61 g of protein, roughly 15% of energy, which meets the RDA for most adults without supplements.
Guideline 8 is explicit about powders: 'protein powders are unnecessary for normal healthy life', most athletes can meet their needs from food, and 'indiscriminate use of excess protein as supplements for prolonged periods can affect health'. Vegetarians meet quality protein needs with pulses, beans, peas and milk or curd; non-vegetarians with fish, poultry, meat and egg. Guideline 10 pairs this with at least 30 to 45 minutes of brisk walking a day, because muscle is built by good-quality protein together with exercise.
Which nutrients do Indian diets commonly lack?
Iron and vitamin B12 are the two gaps with national or trial-level numbers behind them, and both fall hardest on vegetarian diets. The National Family Health Survey 2019-21 (NFHS-5) found that 57% of women and 25% of men aged 15 to 49 are anaemic, up from 53% and 23% in 2015-16, and 67% of children aged 6 to 59 months had some anaemia. A CBC test measures haemoglobin, and Guideline 2 of the 2024 Dietary Guidelines recommends a daily iron-folic acid tablet after 12 weeks of pregnancy, continued through lactation. The ICMR-NIN 2020 iron RDA is 19 mg a day for men and 29 mg for women.
Vitamin B12 occurs only in animal foods, including milk, so lacto-vegetarians depend on how much milk they drink. A 2013 trial in the Nutrition Journal (PMC3851996) screened 51 healthy young lacto-vegetarians at a Pune hospital: 57% were B12 deficient (plasma B12 under 148 pmol/L), with no symptoms. Fourteen days of 400 ml of buffalo milk a day raised plasma B12 from 92.8 to 122.1 pmol/L; the authors conclude that regular milk improved B12 status and call for longer studies. A 2022 abstract in the Indian Journal of Endocrinology and Metabolism (PMC9067870) found that among 65 people with type 2 diabetes on metformin, 77.3% of vegetarians had deficient or borderline B12 versus 27.9% of non-vegetarians. The ICMR-NIN 2020 RDA for B12 is 2.2 µg a day. On My Plate, 300 ml of milk or curd is the vegetarian B12 source, and a full body checkup usually includes B12 and haemoglobin.
How do you read a food label in India?
Start with the ingredient list, then the nutrition table per 100 g, then the per-serve percentages. Guideline 17 of the 2024 Dietary Guidelines explains that ingredients are listed 'in a descending order, with the food item that has been used in highest quantity stated as the first item', and that 'percent RDA per nutrient for every serving of food is also mandatory on the label'. It advises cross-checking any claim against the ingredient list and the table.
Under the FSSAI Labelling and Display Regulations, 2020, regulation 5(3) requires nutritional information per 100 g or 100 ml or per single-consumption pack, plus the per-serve percentage contribution to the Recommended Dietary Allowance, calculated on a reference day of 2,000 kcal, 67 g total fat, 22 g saturated fat, 2 g trans fat, 50 g added sugar and 2,000 mg sodium (5 g salt). The label must state energy, protein, carbohydrate with total and added sugars, total fat with saturated fat, trans fat and cholesterol, and sodium. Regulation 5(14) requires a 'Contains' declaration for eight allergen groups, including gluten cereals, milk, egg, fish, nuts and soy.
Use the figures this way:
- Sugar in the first three ingredients means a sugary product, whatever the front says.
- Compare per-100 g values across brands; serving sizes differ.
- The per-serve %RDA for sodium is against 2,000 mg; a snack at 25% has used a quarter of the day's salt.
Guideline 15 names the foods labels most often flatter: sauces, jams, juices, 'health' drinks, biscuits, cakes and breakfast cereals, and warns that fortifying ultra-processed foods 'does not make them wholesome or healthy'.
When should you see a dietician?
See a dietician when a diet has to be built around a diagnosis, a number on a test, or a life stage with extra needs; My Plate is for healthy adults and NIN's poster says it 'is not for any specific medical condition'. Guideline 9 says weight should come off slowly and that extreme approaches may lead to health hazards; a dietician translates the plate into portions for your weight, activity and budget.
These situations call for an appointment:
- A HbA1c test or fasting glucose in the diabetes or pre-diabetes range, where carbohydrate quality and timing matter.
- A lipid profile with high LDL or triglycerides, where the oil, ghee and trans-fat limits in Guideline 7 need applying to your actual cooking.
- Haemoglobin or B12 below range on a full body checkup, especially on a vegetarian diet.
- Pregnancy, where Guideline 2 adds folic acid for the first 28 days, then calcium and iron-folic acid from 12 weeks.
- Unexplained weight loss, or overweight with a large waist, which the policy brief links to abdominal obesity in 53.1% of urban adults.
In India, look for a dietician in a hospital nutrition department; government medical college hospitals run dietetics OPDs at nominal cost. Bring your test reports and three days of honest food notes. A single session that fixes the cereal-to-pulse ratio, the oil quantity and the salt habit usually does more than any supplement.
