A calorie and protein calculator, and a short quiz to help you choose a programme. Both run in your browser, and nothing you type is stored or sent.

Calorie and protein calculator

An estimate of your maintenance calories, a sensible fat-loss target and a daily protein range.

Units

Goal: fat loss

Enter your details and press the button. Your numbers will appear here.

This is an estimate, not medical advice. Real needs vary from person to person. It is for healthy adults, not for anyone who is pregnant or breastfeeding, under 18, or has a health condition or a history of disordered eating. If that applies, speak to your GP or a registered dietitian first. The NHS describes losing 0.5kg to 1kg a week as a steady pace. Everything runs in your browser. Nothing you type is stored or sent anywhere.

Which programme suits me?

Four questions, then a suggestion you can act on.

1. How would you describe your gym experience?
2. How many days a week can you train?
3. Would you like a weekly check-in with me?
4. What is your budget?
Answer the four questions and your suggestion will appear here.

About the tools

How accurate is the calorie calculator?

It gives an estimate based on a standard formula, and real needs vary from person to person. Treat the number as a starting point, then adjust based on how you feel and how your weight trends over several weeks.

Does the website store what I type into the tools?

No. Both tools run entirely in your browser. Nothing you enter is stored or sent anywhere.

Is the calculator medical advice?

No. It is general information for healthy adults. If you have a health condition, are pregnant or breastfeeding, or have a history of disordered eating, speak to your GP or a registered dietitian first.
