Understanding how many calories your body needs daily is the foundation of a healthy lifestyle. Whether your goal is to lose weight, build muscle, or simply maintain your current weight, our calorie calculator uk offers an easy and reliable way to estimate your daily calorie requirements.
This guide explains everything you need to know about calorie tracking and includes helpful information such as sample meal plans, calories in popular foods, energy expenditure, and the science behind calculating your calorie needs.

What is a Calorie Calculator?
A calorie calculator uk is a tool that helps you estimate the number of calories your body needs each day based on various personal factors such as age, gender, weight, height, and physical activity level. Using a James Smith calorie calculator is especially beneficial because it tailors the results to your specific goals, whether that be weight loss, weight maintenance, or muscle gain.
This calculator gives you:
Your Basal Metabolic Rate (BMR)
Your Total Daily Energy Expenditure (TDEE)
Suggested calorie intake for maintaining, losing, or gaining weight
How the Calorie Calculator Works
Our calorie calculator is based on the well-established Mifflin-St Jeor and Harris-Benedict formulas. These are highly regarded by fitness professionals across the UK for their accuracy.
Step 1: Input Personal Details
Enter your:
Age
Gender
Height (in cm)
Weight (in kg or stones)
Activity level (from sedentary to extra active)
Step 2: Get Your Results
The James Smith calorie calculator will then provide your daily calorie needs for three key objectives:
Maintain current weight
Lose weight (with mild to moderate calorie deficit)
Gain weight (calorie surplus)

Calories Burned from Exercises
Pair our calorie calculator with a calories burned calculator to see how much energy you expend. Here’s how many calories a 155 lb (70 kg) person burns in 1 hour:
Activity | Calories Burned |
Walking (3.5 mph) | 267 kcal |
Jogging (5 mph) | 298 kcal |
Cycling (12-14 mph) | 562 kcal |
Swimming (moderate) | 492 kcal |
Yoga | 149 kcal |
Weightlifting | 112 kcal |
Use our cycling calorie calculator and calories burned calculator to calculate your exact energy output for your workouts.
Understanding TDEE and BMR
Basal Metabolic Rate (BMR) is the number of calories your body needs at rest. Your Total Daily Energy Expenditure (TDEE) includes all activities and gives a complete picture of your daily calorie requirements.
Here is how TDEE is calculated:
Activity Level | Multiplier |
Sedentary | 1.2 |
Lightly Active | 1.375 |
Moderately Active | 1.55 |
Very Active | 1.725 |
Extra Active | 1.9 |
Our James Smith calorie calculator uses these multipliers to deliver accurate daily targets.
Calorie Needs by Gender & Age
Here’s a guide based on UK standards:
Women:
Age 19-25: 1800–2200 kcal/day
Age 26-50: 1800–2000 kcal/day
Age 51+: 1600–1800 kcal/day
Men:
Age 19-25: 2400–2800 kcal/day
Age 26-45: 2400–2600 kcal/day
Age 46+: 2200–2600 kcal/day
Creating a Calorie Deficit
To lose weight, consume fewer calories than you burn. This is called a calorie deficit. Our calorie calculator helps you set a healthy and sustainable target:
Mild loss: Reduce by 250-500 kcal/day
Moderate loss: Reduce by 500-750 kcal/day
Maximum safe reduction: 1000 kcal/day (minimum 1200 kcal for women, 1500 kcal for men)
Again, use our James Smith calorie calculator for realistic guidance.
