Find your Ignite calorie target

Answer a few questions and we’ll work out a daily target that helps you lose fat while protecting your muscle, your energy and your training. It takes about two minutes.

About you

We use these to estimate how much energy your body uses at rest.

Your body
Your week

Be honest rather than hopeful. Use your phone or watch to check your average steps over the last week.

How fast do you want to go?

Slower keeps more muscle and makes training feel better. Most people do best with steady.

How we work it out

We estimate your resting energy using the Mifflin-St Jeor equation, or use your scan figure if you add one. We then add the energy from digestion, your daily steps and your training to estimate what you burn in a typical day.

Your deficit is based on your body weight, then capped at 25% of what you burn and never set below your resting energy. That protects muscle, mood and performance.

Every calculator is an estimate. Your coach will review your weight trend after two weeks and adjust if needed.

This calculator is for healthy adults. If you’re pregnant or breastfeeding, have a medical condition, take medication that affects your blood sugar or blood pressure, or have a history of disordered eating, please speak to your GP before changing how you eat, and let your coach know so we can support you properly.
