How Many Calories Should a Female Eat in a Day?

Calorie needs are not one-size-fits-all. Several factors shape how many calories a female body requires each day:

• Basal Metabolic Rate (BMR): The energy your body uses at complete rest — breathing, circulation, cell repair. This alone accounts for roughly 60–70% of total daily energy use for most people.
• Activity level: Someone with a sedentary desk job uses meaningfully fewer calories than someone who is active throughout the day. Multiplying BMR by an activity factor gives a Total Daily Energy Expenditure (TDEE) estimate.
• Age: Metabolic rate tends to decline gradually with age, meaning calorie needs often shift over time.
• Body composition: Muscle tissue burns more energy at rest than fat tissue, so two people at the same weight can have different needs.
• Health status and medications: Some conditions and medicines influence metabolism and appetite — relevant context for anyone on a GLP-1 weight-management programme.

A General Starting Point for Weight Loss

For females looking to lose weight, many general health references suggest aiming for a daily deficit of roughly 500 calories below maintenance, often landing somewhere between 1,200 and 1,800 calories depending on the individual. These are broad educational ranges — what matters most is finding an intake that supports steady progress, adequate protein, and enough energy to feel well, which is a conversation to have with your prescriber or doctor.

Calories on a GLP-1 Journey

People taking Mounjaro or Wegovy commonly experience reduced appetite, which can make hitting even a modest calorie target feel challenging. Prioritising protein (often cited at 1.2–1.6 g per kg of body weight as a general educational range) helps preserve muscle and support satiety. For a broader look at personalising your numbers, the GLP Trackr calorie calculator hub brings together the key tools in one place. You might also find the page on how many calories you should eat a day a useful companion read.

Knowing your calorie target is one thing — hitting it consistently is another, especially when appetite fluctuates week to week on a GLP-1 medicine. GLP Trackr's AI food photo scan lets you point your camera at a meal and get an instant calorie and protein breakdown without manually searching every ingredient. It is one of the fastest ways to stay on top of your numbers when appetite is low and food prep is minimal.

Once you have a calorie target in mind (ideally agreed with your prescriber or doctor), you can set it directly in the app alongside protein, water, and fibre goals. Your daily check-in then pulls everything together — food logged, targets hit, and a clear picture of whether you are consistently under, over, or right on track. The insights feature can surface patterns over time, such as which days tend to fall short on protein or calories, helping you make small adjustments that add up.

If you want to bring a clear nutrition summary to your next appointment, the app's data is easy to review and discuss with your healthcare professional — far more useful than trying to recall a week's eating from memory.

The calorie ranges on this page are general educational figures. Your individual needs depend on your health history, current medication, and goals — always discuss specific targets with your prescriber or doctor before making significant changes to your intake.
