### How Much Is My Daily Calorie According to BMI?

Use our [Calorie Calculator (BMR)](https://www.seadoc.co/calorie-calculator) to estimate the number of calorie needs per day based on personal activity level to maintain, gain or lose weight. Be aware that any sudden and heavy weight gain or weight loss may cause harm to your health. Please consult with a doctor or registered nutritionist to plan your long-term nutrition and exercise program when your target is to lose 0.5 kg or more per week. Since a healthy amount of calories for adult women ranges from 1,800 to 2,400 calories per day and for men it's 2,000 to 3,200 calories per day.
