Calorie Calculator for Women (UK) – Work Out Your Daily Energy Needs
Keeping an eye on daily energy intake is a simple way to support a healthy, balanced lifestyle. This free calorie calculator for women helps you estimate your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) using either British measurements (stones, pounds, feet and inches) or American units (pounds, feet and inches). Prefer metric? You can switch to kilograms and centimetres in a tap. British units are selected by default for convenience.

How it works
Your BMR is the number of calories your body needs at rest to perform essential functions such as breathing and cell repair. We use the widely trusted Mifflin–St Jeor equation to estimate BMR, then apply an activity factor to estimate your TDEE – the calories you typically burn each day. You can then choose a goal: maintain, gentle fat loss (around a 15% reduction), or lean gain (about a 10% increase).

Why this tool is different

• Designed with women in mind: friendly language, positive guidance and an elegant interface.
• Multiple unit systems: British by default, with easy switching to US or metric.
• Actionable output: a daily target, a clear position bar, and macro suggestions for protein, carbohydrates and fat.
• Mobile-first and fast: lightweight code that loads quickly on phones and tablets.

Tips for healthy progress

• Pair your calorie target with nutrient-dense meals rich in lean protein, whole grains, fruit and veg.
• Aim for regular movement across the week; mix strength work with brisk walks for a balanced routine.
• Hydration and sleep matter more than you think—keep a water bottle handy and prioritise restful nights.
• Remember, numbers are guides. For personal advice, speak with your GP or a registered dietitian.
