Daily Calorie Intake for Women on Mounjaro or Wegovy

A woman's total daily calorie requirement is shaped by several factors working together: basal metabolic rate (the calories your body uses at rest), physical activity, age, and body composition. On a GLP-1 medicine, reduced appetite and the sensation of fullness arriving earlier in a meal can make it easy to fall well below what your body actually needs — which sounds like a win on the scales but can undercut energy levels, muscle retention, and long-term progress.

General calorie ranges (for context, not prescription)

As a broad educational reference, many health bodies suggest the following approximate daily ranges for adult women:

• Sedentary to lightly active: roughly 1,600–1,800 kcal
• Moderately active: roughly 1,800–2,000 kcal
• Active to very active: roughly 2,000–2,400 kcal

These are general population figures — your own number will depend on individual factors. A calorie deficit of around 300–500 kcal per day is commonly referenced as a sustainable range for gradual weight loss, but any specific target should be discussed with your prescriber or doctor, not set in isolation.

Why protein matters alongside total calories

On a GLP-1 medicine, what you eat within your calorie budget matters as much as the total. Protein helps preserve lean muscle when you are eating less overall, and many people find higher-protein meals feel more satisfying with a smaller volume of food. Many sources suggest aiming for around 1.2–1.6 g of protein per kilogram of body weight as a general range, though this is educational guidance rather than a personal prescription.

If you are thinking about what a sustainable calorie level looks like day to day, exploring general daily calorie intake guidance can give useful context, and our dedicated page on ladies' daily calorie intake goes deeper on the practical side. For the broader picture of how a calorie deficit works on a GLP-1 journey, see our guide to building a calorie deficit.

Knowing your rough calorie target is one thing — staying aware of it day to day, especially when appetite is low and meals are smaller, is where most people find tracking genuinely useful. GLP Trackr's AI food photo scan lets you point your camera at a meal and get an instant calorie and protein breakdown, so logging doesn't feel like a chore on days when eating is already an effort.

Once you've set a daily calorie target in the app, your food log feeds directly into it — giving you a live view of where you are by mid-afternoon, which is often when GLP-1 users realise they've barely eaten. The protein target tracker works alongside calories, so you can see at a glance whether you're hitting enough of the right fuel, not just staying under a number.

As always, any specific calorie or nutrition target for your situation is best agreed with your prescriber or doctor — GLP Trackr helps you record and stay on top of what you're eating so those conversations are better informed, not a replacement for them.
