About Weight Loss Calculator By Calculator Online

Estimate how many calories you should eat to lose weight and even get some simple guidelines for losing or maintaining weight.

Our weight loss calculator has been developed after a deep research conducted by Calculator Online certified nutritionists-dieticians. It incorporates detailed nutrition, metabolism, and calorie counting research for healthy weight loss goals.

How Many Calories You Need Per Day To Lose Weight?

According to the 2020–2025 Dietary Guidelines for Americans, daily calorie needs are approximately 2,000 to 3,000 for men and 1,600 to 2,400 for women per day. 

The official health organization of the USA Centers For Disease Control (CDC) suggests an effective calorie-cutting diet and provides BMI calculation guidelines for optimal weight loss.

If your goal comes up with losing weight at a normal pace, then you need to eliminate 500-1000 calories from your daily diet intake. You better keep in mind that:

  • To lose 1 pound of weight, it’s recommended to burn about 3,500 cal in a week
  • Losing 0.5 pounds, a person needs to burn about 1750 cal in a week
  • If a person wants to limit himself to 0.25 lbs, 875 are the recommended calories to lose weight

The science entails that you should eat fewer calories than you expend. When you do this, your body will start consuming energy from the fat stored in it. It will lead to losing excess flab from the body, thereby assisting in healthy weight loss without any health issues.

Maintaining or losing weight requires you to follow a good diet plan and perform regular physical activities.

Do not limit your daily caloric intake to less than 1000 per day. Otherwise,  you will lose more weight while being unhealthy. Remember that the suggested minimum daily calorie allowances are 1500 for men, 1200 for women, and 1350 for nonbinary individuals.

How Do I Calculate Calories To Lose Weight?

To find out the number of calories you need to maintain or lose weight, weigh yourself if your weight is in the healthy range, then just maintain it by consuming the right amount of calories but if not, then cut down your calorie intake.

Your weight loss calories calculations depend upon TDEE and BMR.

BMR contributes to 70% of your daily calorie needs. This is why it provides a baseline to estimate calories per day to lose weight.

Our weight loss calculator is based on the same hypothesis and considers 3 equations that give you an average estimation of your BMR calories. These include:

Mifflin-St Jeor Equation:

BMR = (10.m + 6.25h – 5.0a) + sm = Mass (kg), h = Height (cm), a = Age (years), s = +5 for males, -151 for females

The gender-specific versions of these formulas are as under:

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

If you don’t know the age of a person on the present date, then quickly estimate the age by using the age calculator and put it in the above mentioned equations to obtain precise caloric intake recommendations.

Katch-McArdle Equation:

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

m = Mass (kg), h = Height (cm), a = Age (years)

Your total daily energy expenditure is an estimation of how many calories you burn during a certain activity. Each physical activity has a specific metabolic equivalent of task (MET).

Physical Activity Level MET Value
No Sports/Exercise 0.2
Light Activity 1-3 Times per Week 0.375
Moderate Activity 3-5 Times per Week 0.55
High Activity Everyday Exercise 0.725
Extreme Activity Professional Athlete 0.9

MET values help gauge the intensity of your physical activity, thereby providing a convenient way to estimate your daily calorie expenditure.


Individual’s Details:

Weight (W) = 75 kilograms

Height (H) = 174 centimeters

Age (A) = 26 years

Body fat percentage (F) = 15%

Activity Level:

Moderate Active (Person exercises regularly (3-5 times per week)


Step # 01: BMR Estimation

Using Katch-McArdle Formula

BMR = 370 + 21.6(1 – F)W

BMR = 370 + 21.6(1 – 0.20) * 70

BMR = 370 + 21.6 (0.80) * 70

BMR = 370 + 1209.6

BMR = 1579.6

Step # 02: Estimating TDEE with the activity level provided

Moderate Activity (MET) = 0.55


TDEE = 1579.6 × 0.55

TDEE = 868.78

Step # 03: Daily Caloric Intake For Weight Loss

To lose weight healthily, you should cut off 500 calories after counting calories from your daily intake. 

Calorie Intake = TDEE – 500

Calorie Intake = 868.78 – 500

Calorie Intake To Lose Weight = 368.78

Final Verdict:

The numbers are estimations only that might include human error as well. So to get a more precise value, this weight loss calculator gives you a comprehensive range of calories subjected to your varying goals and daily life routines.

Zigzag Schedule For Calorie Intake:

This calorie cycling is an evident approach to losing weight by consuming calories in a zigzag manner. When you eat the same number of calories each day, a time will come when your body gets used to it. In this condition, the plateau of weight loss happens and your body does not lose more weight after a certain time. This is why zigzag calorie cycling states that a person needs to eat foods by changing calorie numbers daily.

What You Should Do?

You should follow the below-mentioned steps:

  • Eat certain types of foods containing 2300 cal for the first three days
  • For the remaining four days, 1775 cal needed to lose weight

Following this practice will keep your total calorie ingestion 14000 weekly but in a more effective way. The combination of high and low-calorie consumption allows you to eat different foods flexibly.

How To Reduce Calories For Weight Loss?

Intermittent Fasting:

Fasting will help you lose 0.55 to 1.65 pounds per week (0.25–0.75 kg). During fasting hours, your body is shifted to fat-burning mode and consumes energy from it.

Regular Workout:

Workout increases your physical activity level and it helps to reduce calories by burning them. Exercising daily will improve your resting metabolic rate (RMR), build lean mass, help regulate stress, and support long-term weight maintenance. Here, you can get different exercises proposed by weight loss calculator that is tailored to your weight loss journey. Following a proper workout plan will certainly help you increase lean mass, reduce stress levels, and maintain weight for a long time.

Stop Drinking Your Calories:

Never drink your calories as it can cause type 2 Diabetes and severe obesity. Intaking soda drinks not only increases your calorie consumption but will also increase your hunger later on. Cut back your sweetened drinks.

Make Food Swaps:

Never stop eating a healthy diet enriched in nutrients. You can eat them in a sufficient quantity and deliver enough calories to lose weight or to maintain a healthy weight. So after counting balancing high-calorie and low-calorie foods will be a great way to lose fat.

Fill up with Water, Protein, and Fiber:

A healthy diet consisting of sufficient water, moderate protein, and a controlled amount of high-saturated carbohydrates will keep your stomach full while delivering fewer calories. Some types of foods can enhance the rate of the calories burned like tea, coffee, etc. 

Reduce Portion Sizes:

This is an effective approach to adopting a controlled calorie deficit to lose weight. In the start, cut a smaller number of calories from your daily diet and then make arrangements to get far better results. For convenience, you can get the assistance of the weight loss calculator that customizes your journey by estimating the optimum calorie cut from your daily intake.


How Many Calories Should I Eat a Day To Lose Weight?

  • Equation For Men: Eat different foods having 2000 – 3000 cal in a day for weight loss
  • Equation For Women: 1500 cal per day
