Calculators for food and wellbeing

How the three calculators fit together

Each tool answers a different question, and they work best side by side. BMI is a rough snapshot: where your weight sits relative to height on a population scale. The calorie calculator is about direction: roughly how much energy keeps you steady, and what a gentle change might look like. The water calculator is about daily comfort and energy, and changes with weather and activity.

A sensible order: check BMI once for context, use the calorie result to plan portions and meals for a few weeks, and keep water as a daily habit. None of them sees your muscle mass, hormones, medication or history, so treat the numbers as starting points.

Gentle healthy habits that actually stick

• Sleep first. Tired days make food choices harder; a steady bedtime helps more than any rule.
• Protein and vegetables at every meal. They keep you full and make portion sizes easier without counting.
• Walk daily. Twenty to thirty minutes is enough to feel the difference in mood and energy.
• Water in sight. A glass on the desk or a bottle in the bag works better than a reminder app.
• Plan meals, not restrictions. Knowing what dinner is tonight prevents the late-evening snack raid.

From numbers to plates

Once you have your numbers, the kitchen is where they turn into habits. Our light and healthy recipes show calories and macros per portion, so you can build a day that fits your result without weighing everything forever. Change one thing at a time: a better breakfast this week, an extra vegetable at dinner next week.

Be kind to yourself about ups and downs. Weight naturally shifts from day to day with water, salt and the menstrual cycle; look at trends over weeks, not single mornings.

Water works the same way: if the calculator suggests more than you drink now, add one glass a day for a week rather than doubling overnight.

When to see a doctor

These calculators are for general information and are not medical advice. Talk to a doctor if you are pregnant or breastfeeding, have a chronic condition such as diabetes, heart or kidney disease, take medication that affects appetite or fluids, notice sudden unexplained weight change, constant thirst, or if food and body image are causing you distress. A professional can give you targets that fit you, not an average.
