✓ Your Results Are Ready

Here's your results,

Your results are based on the information you input into the questions.

Total Daily Energy Expenditure (TDEE)

—

This is the energy you need to consume daily in order to maintain your current weight.

Watch: what your number actually means

📨 I've sent a more detailed breakdown of this to . Check your emails to see those results.

⚠️ A note on your numbers

A standard calorie deficit based on your goal would bring your target lower than we'd recommend. As we get older, fuelling the body properly becomes more important, not less. We've set your target at a safe minimum of 1,200 calories. The real results come from what you eat and how you train — not from cutting as low as possible.

Want a full plan built around these numbers?

Your calorie target is a starting point. The Health MOT goes further — 45 minutes with a coach, and you leave with a personalised 12-week plan built around your life, your food, and your goals.
