Weight Loss Calculator (Your Daily Calories):

This calculator estimates your daily calorie needs for healthy weight loss. To lose weight, you need to create a calorie deficit (burn more calories than you consume). It also functions as a calorie calculator, helping to determine the calorie burn required for your weight goal. Maintaining a healthy calorie balance is crucial for weight loss success. Use this weight loss estimator as a starting point to set your personalized plan based on your daily calorie needs.

Tool Creation: We (Team) of calculator-online created this tool using the scientific formulas that we mentioned below. The calculations are reviewed by our Experts and do best to provides reliable estimations as possible.

Formulas Used by This Weight Loss Calculator:

These are the different equations used for determining calorie needs:

Mifflin-St Jeor Formula:

BMR = (10.m + 6.25h – 5.0a) + s m = Mass (kg), h = Height (cm), a = Age (years)

The gender-specific versions of this formula is as follows:

Equation For Men: 10 x weight (kg) + 6.25 x height (cm) – 5 x age (y) + 5

Equation For Women: 10 x weight (kg) + 6.25 x height (cm) – 5 x age (y) – 161

Katch-McArdle Formula:

Katch = 370 + (21.6 * LBM) LBM = lean body mass

Revised Harris-Benedict Equation:

Men: (13.397m + 4.799h – 5.677a) + 88.362

Women: Harris-Benedict = (9.247m + 3.098h – 4.330a) + 447.593

Body Fat Percentage Equation:

BMR = 370 + (21.6 x (1 – F) x W)

TDEE (Total Daily Energy Expenditure) Equation:

TDEE = BMR x Activity Level

Calorie Deficit Equation:

Calorie Deficit = Calories In – Calories Out

TDEE And BMR For Weight Loss:

The two most important factors that help to find out your calorie intake to lose weight are:

BMR (Basal Metabolic Rate):

  • It’s the estimated amount of calories that the body burns in the rest state for basic functions
  • The BMR is affected by factors like age, gender, height, weight, and the body composition of individuals

TDEE (Total Daily Energy Expenditure):

  • TDEE represents the total number of calories the body burns in a day. It includes your BMR and the number of calories burned by the physical activities performed daily
  • The calculation of TDEE requires your BMR and physical activity level (body movement)

How They Help With Weight Loss:

  • You need to create a calorie deficit to lose weight. It means to eat less calories than your estimated Total Daily Energy Expenditure (TDEE)
  • Knowing the BMR serves as the starting point in understanding the amount of calories that your body needs for basic functions. It's an estimate and individual variations exist
  • Understanding your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) can empower you to make informed decisions about calorie intake for weight management goals. Our calorie calculator can help you estimate the daily calorie needs for weight loss (creating a calorie deficit), weight gain (consuming more calories than your TDEE), or weight maintenance. Remember that individual metabolism can vary, so consider this information as a starting point for weight loss journey!

Physical Activity Level & Weight Goals:

The physical activities that you perform in a day impact your daily calorie needs. Physical activity and weight loss goals are connected. Both of them are necessary for creating an effective weight loss plan.

Physical Activity Multiplier (PAL):

Physical Activity LevelExamplesMET Value
No Sports/ExerciseSitting, Reading, Watching TV, etc.1.2
Light Activity 1-3 Times per WeekWalking, Light Gardening, etc.1.375
Moderate Activity 3-5 Times per WeekBrisk Walking, Jogging, Swimming, etc.1.55
High Activity Everyday ExerciseRunning, Cycling, Heavy Gardening, etc.1.725
Extreme Activity Professional AthleteIntense Training, Competitive Sports, etc.1.9

How Many Calories Should I Eat On Average?

According to the latest edition of the USDA Dietary Guidelines, daily calorie needs are approximately 1,600 to 2,600 for men and 1,400 to 2,200 for women per day. The individual needs may differ based on age, gender, height, weight, and activity level. If you are unsure about how long it will take to lose weight, use our weight loss calculator that takes the target date and tells you about calories you need to eat within a specific time to lose weight.

Calories To Lose Weight:

  • 1 Pound Per Week: Create a good calorie deficit of approximately 3,500 calories over a week(roughly 500 calories per day to lose weight). (Reference: How Well This Rule Predicts Successful Weight Loss)
  • 0.5 Pounds Per Week: It requires you to make a calorie deficit of about 1750 calories per week(approximately 250 calories per day to lose weight)
  • 0.25 Pounds Per Week: To lose 0.25 lbs weight per week a deficit of 1250 calories per week is recommended (roughly 175 calories for weight loss per day)

Note: A safe calorie deficit typically falls within the range of 500-1000 calories per day. Don't restrict calories below recommended minimums (1,500 for men, 1,200 for women, 1,350 for non-binary individuals). As, this can be unhealthy and lead to nutrient deficiencies.

Tips To Lose Weight:

Set Weight Loss Goals:

Set a goal for losing a specific weight over the week ( safe range: 1–2 lbs per week).

Exercise:

Exercising daily improves your resting metabolic rate (RMR), builds lean mass, keeps you active, and supports long-term weight maintenance. It has a lot of health benefits, including boosting your mood, strengthening your cardiovascular system, and reducing your blood pressure. Regular exercise helps to burn calories. It includes:

  • brisk walking
  • Jogging
  • Running
  • Cycling
  • swimming
  • Weight Lifting

Eat Healthy Food:

A healthy diet consists of sufficient water, protein, and a controlled amount of sugar and refined carbohydrates. It's necessary to eat good and healthy food so that you can lose weight healthily. Enhance the use of vegetables, fruits, and whole grains, and cut down the use of sugar. Practice mindful eating and pay attention to portion sizes.

Drink Healthy Beverages:

Stop drinking sugary drinks like soda, sports drinks, energy drinks, sweetened coffees and teas, and alcoholic beverages.

Stay Hydrated:

As we know water is essential for various bodily processes, including digestion and nutrient absorption. Proper hydration can also aid in weight loss.

Get Enough Sleep:

Having enough sleep (7-8 hours) is important for weight loss. Poor sleep can disrupt hormones that regulate appetite, often leading to increased cravings and creating difficulty in losing weight. Poor sleep can also impact on your overall health.

Try Intermittent Fasting:

Fasting will help to get rid of extra body fat by taking energy from it, resulting in shedding extra pounds from your body. It is suggested to consult with a doctor before starting intermittent fasting, as it might not be suitable for everyone!
