The short version
- 1
For Indians, a BMI over 23 now counts as obesity, and a waist of 90 cm or more (men) or 80 cm or more (women) is a warning sign.3
- 2
Aim for about 500 fewer calories a day. Losing 0.5–1 kg a week is the pace that’s safe and lasts.3,4,9
- 3
Cut cereals and packaged snacks first. Keep the dal, vegetables and curd.5,6
Your number
Where does your BMI sit?
India redefined obesity in 2025. The cut-offs for Indians are lower than the ones you see online.
24.2kg/m²
Obesity, grade I
23–24.9. Under India’s 2025 definition this is obesity: Stage 1 if it isn’t yet affecting your health or daily life.
Slide to your own number. BMI is your weight in kg divided by your height in metres, squared.
Measure your waist too: fasting, standing straight, with a tape level just above your hip bone, at the end of a normal breath out. Keep it under half your height: under 80 cm if you are 160 cm tall, under 87.5 cm at 175 cm.3
Your calories
How big a cut, and how fast
- Sedentary woman, 55 kg
- Needs about 1,660. A full 500-calorie cut leaves about 1,160, below the 1,200–1,500 most guidance suggests for women. So let moving more do part of the work.7,8
- The floor
- Don’t go below 1,000 calories a day. ICMR-NIN says weight-loss diets should be followed with a doctor and dietitian.4
What to change
Cut here first
- Chips, biscuits, sweets and juicesFruit, curd or roasted chana
These “other foods” already supply 10% of urban Indians’ calories.6
- A full mound of rice, or four rotisHalf the cereal, more sabzi and dal
ICMR-NIN: people trying to lose weight may cut down on cereals.5
- Two spoons of sugar in every chaiA little less each week
Keep added sugar within 25–30 g a day, all of it counted.5
- Fruit juiceThe whole fruit
ICMR-NIN’s plate prefers fresh fruit to juice.5
Your day
Meals that work
- Breakfast
- 3 idlis, 2 dosas or a cup of upma, plus protein: 2 eggs (about 12.6 g) or a bowl of curd. It’s optional: in 13 trials, eating breakfast didn’t help weight loss.4,12,19
- Lunch
- Sabzi and salad, a katori of dal, one or two rotis and curd: the plate in miniature.5
- Snack
- Fruit, curd, roasted chana, or 10 almonds (about 85 calories).4
Vegetarian? In 12 trials, vegetarian diets lost about 2 kg more than non-vegetarian ones.15 Keep protein up while you cut: higher-protein diets kept a little more muscle.16 Our protein guide shows how much your meals give you.

The next 12 weeks
One change at a time
Small changes that stack, at a pace you can hold.
Weeks 1–2
Measure, then cut the easy calories
Note your waist and weight. Drop sugary drinks and packaged snacks.
Weeks 3–6
Smaller cereal, bigger sabzi
Halve the rice or roti; add dal, vegetables and curd. Walk daily, building towards 60 minutes.3
Weeks 7–10
Add strength
Resistance exercise at least 3 days a week, alongside the walking.3
Weeks 11–12
Measure again
At 0.5 kg a week, that’s up to about 6 kg. Plateaus are normal: the body adjusts slowly.3,10
Myths
What you might hear
They say
“Crunches burn belly fat.”
They say
“Skip dinner to lose weight.”
Actually
In a year-long trial, adding an eating window to calorie cutting gave no significant extra loss: 8.0 kg against 6.3 kg.11
They say
“Never skip breakfast: it boosts metabolism.”
Actually
In 13 trials, breakfast eaters ate about 260 calories more a day and didn’t lose more weight.12
They say
“Crash diets work faster.”
They say
“A BMI of 24 is normal.”
Actually
Not for Indians. Since 2025, a BMI over 23 counts as obesity.3
They say
“You have to give up rice and roti.”
See a doctor first if
- You are losing weight without trying.
- Everyday activities leave you breathless, with palpitations, or with knee, hip or back pain.
- You have diabetes, heart disease, sleep apnoea, fatty liver, high cholesterol or blood pressure, PCOS or depression.
- You are pregnant or breastfeeding.
Get a check before starting exercise if you have heart or other health problems. Don’t take weight-loss pills without a doctor.
Obesity that affects your health needs a medical plan, not just a diet.3,4,17
