Frequently Asked Questions (FAQs)
- What is a healthy BMI range for Indian adults?
- According to WHO Asia-Pacific guidelines, a healthy BMI for Indian adults is 18.5–22.9 kg/m². BMI below 18.5 is underweight, 23–27.4 is overweight, and 27.5 or above is obese.
- What is the difference between BMI and BMR?
- BMI (Body Mass Index) measures body weight relative to height to screen for weight categories. BMR (Basal Metabolic Rate) measures the calories your body burns at complete rest to maintain basic life functions like breathing and circulation.
- How many calories should I eat per day to lose 1 kg per week?
- To lose 1 kg per week, you need a 1,100 calorie daily deficit (since 1 kg fat ≈ 7,700 calories). Most dietitians recommend a moderate deficit of 500–600 calories/day for safe, sustainable weight loss of 0.5 kg/week.
- How much water should I drink per day?
- General guidelines recommend 35 ml per kg of body weight daily. A 70 kg adult should drink approximately 2.4–2.5 litres per day. Requirements increase with physical activity, heat, and altitude.
