Bmi Calculator Calorie Intake To Lose Weight


Losing weight requires a combination of factors, one of which is managing your daily calorie intake. This intake is influenced by various elements such as your weight, height, age, gender, and activity level. Our Bmi Calculator Calorie Intake To Lose Weight is designed to help you estimate the number of calories you should consume daily to achieve your weight loss goals. By integrating your BMI (Body Mass Index), it offers a more customized and accurate estimate.


Our calculator employs a two-step approach to determine your daily calorie intake for weight loss:

  1. Calculate Basal Metabolic Rate (BMR): The first step involves using the Mifflin-St Jeor Equation to calculate your BMR. The equation differs based on gender:
    • For males: BMR = 10 * weight + 6.25 * height - 5 * age + 5
    • For females: BMR = 10 * weight + 6.25 * height - 5 * age - 161
  2. Determine Total Daily Energy Expenditure (TDEE): Once we’ve determined your BMR, we factor in your activity level to estimate your TDEE. TDEE considers how active you are throughout the day and is calculated by multiplying your BMR by a specific multiplier:
    • Sedentary (little or no exercise): BMR * 1.2
    • Lightly active (light exercise or sports 1-3 days a week): BMR * 1.375
    • Moderately active (moderate exercise or sports 3-5 days a week): BMR * 1.55
    • Very active (hard exercise or sports 6-7 days a week): BMR * 1.725
    • Super active (very hard exercise, physical job, or training): BMR * 1.9
  3. Daily Calorie Intake for Weight Loss: To achieve weight loss, it is commonly recommended to create a calorie deficit of around 500 calories per day. Therefore, the calculator provides you with a daily calorie intake that is 500 calories less than your TDEE.

How to Use

Using the Bmi Calculator Calorie Intake To Lose Weight is a straightforward process:

  1. Input Weight: Enter your current weight in kilograms.
  2. Input Height: Enter your height in centimeters.

  5. Select Activity Level: Pick your activity level from the list that matches your typical daily activities.
  6. Click “Calculate”: After providing this information, click the “Calculate” button.
  7. View Daily Calorie Intake: The calculator will generate an estimate of the number of calories you should consume daily to support your weight loss goals.


For example, if you’re a 30-year-old female, weigh 70 kg, stand at 165 cm, and have a moderately active lifestyle, the calculator will estimate that you should consume approximately 1,693.75 calories per day to lose weight effectively.


  1. What is BMI, and why is it used in the calculator?
    • BMI, or Body Mass Index, is a measure of body fat based on height and weight. It is used in the calculator to provide a more personalized and accurate estimate of your calorie intake for weight loss.
  2. Can I use this calculator for weight maintenance or weight gain goals?
    • Yes, this calculator can be used for weight maintenance or gain by adjusting your daily calorie intake accordingly. For maintenance, you would match your TDEE, and for weight gain, you would consume more calories than your TDEE.
  3. Is a 500-calorie deficit safe for weight loss?
    • A 500-calorie deficit is a common recommendation and generally considered safe for gradual weight loss. However, it’s important to consult with a healthcare professional or nutritionist to ensure it’s appropriate for your individual needs.


The Bmi Calculator Calorie Intake To Lose Weight is a valuable tool for individuals striving to manage their calorie intake and achieve their weight loss goals. It provides a personalized estimate that considers your BMI, age, gender, and activity level. By utilizing this calculator, you can embark on a more informed and effective weight loss journey, making it easier to reach your desired fitness and health objectives.
