How to use the Calorie Counter

  1. Enter your age, height, weight, activity level and goal. The calculator shows your maintenance calories (BMR × activity) and a daily target, with the formula and its sources.

  3. Log faster with recent foods, favourites, your own foods from a label, saved meals and quick add for a calorie number.
  4. Watch calories left and your protein, carbs and fat bars fill through the day. Change your target or macro split any time.
  5. See your week, month and quarter against your target, your weight trend and your logging streak. Install the app and sign in for meal reminders.

Frequently asked questions

How many calories should I eat a day to lose weight?
Start from your maintenance calories: your basal metabolic rate (BMR) from the Mifflin-St Jeor equation, multiplied by an activity factor from 1.2 (mostly sitting) to 1.9 (very hard daily exercise or physical work). Eating about 500 kcal a day less than that is the usual way to lose around 0.5 kg (1 lb) a week. The counter never suggests less than your BMR, or 1,200 kcal (female formula) or 1,500 kcal (male formula), whichever is higher. These are estimates for healthy adults, not medical advice.
How do I calculate my calorie deficit?
Your deficit is your maintenance calories minus what you eat. A common rule of thumb is that about 7,700 kcal equals 1 kg of body fat (3,500 kcal per pound), so 0.5 kg a week is about 550 kcal a day. The rule overestimates long-term loss because your body adapts as you lose weight, so treat the target as a starting point and adjust it from your weight trend.
Is there a free calorie counter with no ads?
Yes. Every logging feature here is free: food search, portions, macros, your own foods, saved meals, charts, streaks and sync. There are no ads and this page loads no analytics or session recording. A paid plan only adds more reminder schedules. Barcode scanning is planned and will be free too.
How accurate is calorie counting?
Food values are averages: the same food varies by variety, ripeness and preparation, and labels may legally differ from the real content. People also tend to underestimate portions. Weighing food in grams and using verified values, like the USDA FoodData Central figures this counter uses, removes the biggest errors. Your equation-based target can be off by 10 % or more for an individual, so watch your weight trend over a few weeks.
How many calories do I burn a day doing nothing (BMR)?
Your basal metabolic rate is the energy you use at rest. With the Mifflin-St Jeor equation it is 10 × weight in kg + 6.25 × height in cm − 5 × age, plus 5 for the male formula or minus 161 for the female one. For a 30-year-old, 70 kg, 175 cm man that is about 1,650 kcal a day; for a 30-year-old, 60 kg, 165 cm woman about 1,320 kcal.
