Let's face it – knowing exactly how many calories you need can be confusing. That's why we've developed simple yet powerful calculators that give you accurate, personalised targets that actually work for your body and lifestyle.
Why Those Generic Calorie Guidelines Don't Work
Ever followed the standard "eat 1,500 calories to lose weight" advice and wondered why it didn't work? That's because your body's energy needs are unique. What works for your friend or colleague might be completely wrong for you.
Our calculators take into account your current weight and height, age and sex, how active you really are (not just "moderate" or "active"), and what you're actually trying to achieve. This means you get calorie targets that are spot on for YOU, not some imaginary average person.
How Our Calculators Give You Better Results
Our tools use the most respected scientific methods to work out your calorie needs, but we've made them dead simple to use. You won't need a science degree to understand your results!
We combine several trusted formulas that nutritionists and dietitians use, then present your results in a way that makes practical sense for everyday life.
More Than Just Basic Sums
Unlike those quick online calculators that ask just three questions, our system works out a realistic range that suits your body type, takes into account your past weight changes, looks at the specific activities you do (because dog walking burns different calories than swimming), and adapts as your weight and fitness levels change.
Tailored Calorie Targets for Whatever You're Trying to Achieve
If You Want to Lose Weight
Our weight loss calculations will give you a sensible calorie target that creates results without starvation. We'll help you find the right balance to lose fat but keep your muscle, with adjustments that change as your weight drops. Most importantly, you'll get realistic targets you can actually stick to.
If You Want to Stay Where You Are
Maintaining your weight might sound easy, but it takes the right balance. Our calculations help you find your true maintenance level, allow for those busy days and quieter days, build in room for the occasional treat, and keep your weight stable without obsessive tracking.
If You Want to Build Muscle or Gain Weight
For those looking to gain, we'll help you add the right amount of calories for muscle growth without excess fat. You'll learn how to get enough protein at the right times, fuel your workouts properly, and make steady, healthy progress.
Real People, Real Results
Sarah's Story
Sarah, a nurse from Manchester, had been trying to lose weight with a standard 1,500 calorie plan she found online. After three frustrating months with barely any results, she tried our calculator. It showed she actually needed 1,850 calories because of her active job and regular gym sessions. Once she stopped under-eating, she lost over 5kg in 12 weeks and had much more energy for her shifts and workouts.
James's Experience
James, 42, from Bristol, couldn't understand why he kept gaining weight despite following a typical 2,000 calorie maintenance plan. Our precise calculations showed his desk job and body type meant his actual maintenance level was 1,780 calories. This small but important difference helped him stop the gradual weight gain and feel better about his eating habits.
How It Works (Without the Complicated Bits)
Using our calculators is straightforward:
- Enter your basic details (height, weight, age, sex)
- Tell us about your daily activity and exercise
- Choose what you're trying to achieve
- Get your personalised calorie target
That's it! No complicated maths or scientific jargon – just a clear, reliable number you can actually use.
More Than Just Calories
While knowing your calorie target is crucial, our calculators also help with the right balance of protein, carbs and fats for your goals, how to adjust your eating on more active or rest days, simple meal timing suggestions for better results, and practical targets that fit your real life, not an ideal world.
Why Accuracy Matters
Getting your calorie targets right isn't about being perfect – it's about being effective. Just a small adjustment of 100-200 calories can mean the difference between losing weight steadily or hitting frustrating plateaus, maintaining your weight easily or constantly battling the scales, and building lean muscle or adding unwanted fat.
Our precise calculations give you this accuracy without the headache of complex formulas or confusing nutrition science.
