Most Common Questions asked by customers regarding Macro and Calorie Counter UK .
Macros (macronutrients) are the three main components of your diet that provide energy: protein, carbohydrates, and fats.
- Protein: Supports muscle repair, immune function, and satiety. Higher protein intake during weight loss helps preserve lean muscle and keeps you feeling fuller. Sources include chicken, fish, eggs, Greek yoghurt, tofu, lentils, and beans.
- Carbohydrates: The body’s preferred energy source, especially for the brain and exercise. Focus on complex carbs like oats, wholegrain bread, brown rice, sweet potatoes, fruits, and vegetables. The NHS recommends starchy carbohydrates form just over a third of your diet.
- Fats: Essential for hormone production, brain health, and absorbing fat-soluble vitamins (A, D, E, K). Prioritise unsaturated fats from olive oil, avocado, nuts, seeds, and oily fish, while limiting saturated fats.
Tracking macros offers a clearer picture of nutrition than calories alone, as the balance affects appetite, energy, and muscle retention during weight loss.
Step 1 – Basal Metabolic Rate (BMR)
Your BMR is the number of calories your body burns at rest, just to maintain essential functions. The calculator uses the Mifflin-St Jeor equation, a highly accurate method for predicting resting energy expenditure.
Step 2 – Total Daily Energy Expenditure (TDEE)
TDEE is your BMR multiplied by an activity factor reflecting your typical daily activity. This accounts for calories burned through exercise and daily movement.
Step 3 – Goal adjustment and macro split
Based on your goal—fat loss, maintenance, or muscle gain—the calculator adjusts your TDEE and divides calories into a recommended protein, carb, and fat split to support your objective.
Tracking macros tells you what you eat, not just how much. Two people could consume the same calories but see different results depending on macro distribution. Tracking macros can help:
- Lose fat while preserving muscle mass
- Reduce hunger and cravings with adequate protein and fibre
- Boost energy and exercise performance
- Build a healthier, balanced relationship with food
- Stay on track during GLP-1 weight loss treatments like Mounjaro or Wegovy
Macros and weight loss injections
If you are using Mounjaro (tirzepatide) or Wegovy (semaglutide), appetite is often reduced. It’s crucial to make every calorie count. Using the macro calculator helps set realistic daily protein targets—usually 1.2–2.0 grams per kilogram of body weight for adults aiming for fat loss—so smaller meals still provide necessary nutrients.
The British Dietetic Association provides free nutrition guides to support healthy eating choices.
- Track meals with an app or diary: Apps like MyFitnessPal, Cronometer, or Nutracheck help log meals and calculate daily macros.
- Weigh your food: Eyeballing portions can underestimate calories. Digital kitchen scales provide accuracy.
- Aim for consistency: Focus on hitting protein targets daily; allow flexibility with carbs and fats, staying within ±100–150 calories of your target.
- Reassess every 4–6 weeks: Recalculate macros as weight changes, especially during GLP-1 treatment, to keep targets accurate.

Yes. It is completely free and requires no account or personal data beyond what’s necessary for calculation.
It uses the Mifflin-St Jeor equation, a widely validated method for estimating resting metabolic rate. Individual metabolism may vary, so adjust targets as needed.
A daily deficit of 500 calories below TDEE typically supports a safe fat loss of around 0.5 kg (1 lb) per week, in line with NHS guidance. The calculator applies this automatically when selecting a fat loss goal.
Yes. It helps you manage calorie intake and protein targets while appetite is reduced. For personalised advice, consult our clinical team via a free online consultation.
Not necessarily. Many track consistently for a few months to learn portions and nutrition, then move to a more intuitive approach once habits are established.
