Free Health Tools & Nutrition Calculators

How to use these health calculators

Start with the basics: check your BMI and waist-to-height ratio to understand your weight and belly-fat risk. Then find your daily energy needs with the calorie calculator or TDEE calculator, and split them into protein, carbohydrate and fat with the macro calculator. If you have a weight goal, the weight loss calculator shows a realistic timeline.

Healthy habits matter just as much as numbers. Use the water intake calculator — with extra for hot Gulf summers — and check that you are getting enough fibre and not too much added sugar. Planning to fast? The intermittent fasting calculator includes a Ramadan planner for suhoor, iftar and hydration.

Why use Nutricare’s calculators?

• Evidence-based formulas — Mifflin-St Jeor, WHO and NICE cut-offs, CDC growth charts, IOM pregnancy guidelines and more, with sources on every page.
• Metric and US units — kilograms and centimetres or pounds and feet/inches.
• Made for our community — Asian BMI cut-offs, hot-climate hydration, Ramadan planning and familiar foods like dal, roti, rice and dates.
• Clear results — every tool shows low, normal and high ranges and practical next steps.
• Free and private — calculations run in your browser; nothing you type is stored.

Please remember: calculators give general estimates for education. They do not replace advice from your doctor or a qualified nutritionist, especially if you are pregnant, under 18, have a medical condition or take medication.
