Daily Calories Calculator
Estimate your daily calorie needs based on your age, body measurements, activity level, and weight goal.
Understanding how many calories your body needs each day is an important part of maintaining a healthy lifestyle. Whether your goal is to lose weight, maintain your current weight, or gain weight, knowing your daily calorie requirements can help you make informed decisions about your diet and physical activity.
Our free Daily Calories Calculator helps you estimate the number of calories you should consume daily based on your age, biological sex, height, weight, activity level, and weight-management goal.
The calculator uses the Mifflin-St Jeor equation to estimate your basal metabolic rate (BMR). It then considers your daily activity level to determine your estimated total daily energy expenditure (TDEE), also known as maintenance calories.
You can choose a calorie deficit for weight loss, maintain your current calorie intake, or select a calorie surplus to support weight gain.
In addition to your recommended daily calories, the calculator provides your estimated BMI, BMI category, weekly weight change, and suggested calorie allocations for three or four meals per day.
Whether you are starting a weight-management journey or reviewing your current eating habits, our daily calorie intake calculator provides a practical starting point for planning your nutritional needs.
What Is a Daily Calories Calculator?
A daily calories calculator is an online tool that estimates how many calories your body requires each day.
Calories measure the energy that your body obtains from food and beverages.
Your body uses this energy for essential functions, including breathing, blood circulation, digestion, temperature regulation, movement, and physical activity.
Your daily calorie requirement depends on several factors, including your body size, age, activity level, and individual metabolism.
For example, a person who exercises regularly generally requires more calories than someone with a sedentary lifestyle, assuming other relevant factors are similar.
A daily calorie calculator helps estimate three important energy targets:
Maintenance calories: The approximate daily calorie intake needed to maintain your current weight.
Weight-loss calories: A calorie target below maintenance that may support gradual weight loss.
Weight-gain calories: A calorie target above maintenance that may support weight gain.
Our calculator also estimates how your selected calorie adjustment could affect your body weight over one week.
These estimates can help you establish realistic starting points for nutrition planning.
Why Is Knowing Your Daily Calorie Requirement Important?
Knowing your estimated calorie needs can make weight management more structured.
Without understanding your maintenance calorie requirement, it can be difficult to determine whether your current eating habits are likely to support weight loss, weight maintenance, or weight gain.
For Weight Loss
Weight loss generally requires a calorie deficit.
A calorie deficit occurs when you consume fewer calories than your body expends over time.
For example, if your estimated maintenance requirement is 2,500 calories and you consume 2,000 calories, your estimated daily deficit is 500 calories.
For Weight Maintenance
Weight maintenance generally involves consuming approximately the same amount of energy your body uses.
If your body burns around 2,200 calories daily, consuming approximately 2,200 calories may help maintain your current weight.
For Weight Gain
Weight gain generally requires a calorie surplus.
For example, if your maintenance requirement is 2,500 calories and you consume 2,750 calories, you have an estimated surplus of 250 calories daily.
When combined with resistance training and sufficient protein, an appropriate calorie surplus may help support muscle growth.
However, a calorie surplus does not guarantee that all weight gained will be muscle.

How to Use the Daily Calories Calculator
Using our free Daily Calories Calculator is simple. Follow the instructions below to calculate your estimated daily calorie needs.
Step 1: Enter Your Age
Enter your age in years.
The calculator accepts ages between 18 and 120.
Age affects estimated basal metabolic rate because resting energy expenditure often changes as people get older.
For example, two individuals with the same height and weight but different ages may have different estimated calorie requirements.
Step 2: Select Your Biological Sex
Choose male or female.
The calculator uses your selection when applying the Mifflin-St Jeor equation.
The equation includes different constants for males and females.
These sex-based estimates do not account for every individual difference in physiology or body composition.
Step 3: Enter Your Weight
Enter your current body weight.
You can choose between:
- Kilograms (kg)
- Pounds (lb)
For example:
180 pounds × 0.45359237 = 81.65 kilograms.
The calculator automatically converts pounds into kilograms before calculating your results.
For valid calculations, your weight must be equivalent to 25–350 kilograms.
Step 4: Enter Your Height
Enter your height using one of the available units:
- Centimeters (cm)
- Feet (ft)
- Inches (in)
The calculator converts your height into centimeters for the BMR calculation and meters for BMI.
For example:
175 cm = approximately 68.9 inches.
When entering height in feet, use decimal feet.
For example, 5 feet 8 inches equals approximately 5.67 feet.
Entering 5.8 feet would represent a different measurement.
The accepted height range is equivalent to 100–250 centimeters.
Step 5: Select Your Daily Activity Level
Choose the activity level that best represents your normal lifestyle.
The calculator offers five options.
| Activity Level | Description | Multiplier |
|---|---|---|
| Sedentary | Little or no exercise | 1.20 |
| Lightly active | Light exercise 1–3 days weekly | 1.375 |
| Moderately active | Exercise 3–5 days weekly | 1.55 |
| Very active | Hard exercise 6–7 days weekly | 1.725 |
| Extra active | Very intense exercise or physically demanding job | 1.90 |
Your activity level plays an important role in estimating maintenance calories.
For example, someone with a BMR of 1,700 calories would have the following estimated daily energy requirements:
| Activity Level | Estimated Maintenance Calories |
|---|---|
| Sedentary | 2,040 kcal |
| Lightly active | 2,338 kcal |
| Moderately active | 2,635 kcal |
| Very active | 2,933 kcal |
| Extra active | 3,230 kcal |
These values demonstrate how activity can influence daily energy expenditure.
Choose your activity level based on your typical routine rather than occasional exercise sessions.
Step 6: Select Your Weight Goal
Choose the goal that best matches your current objective.
The calculator provides five options.
| Weight Goal | Calorie Multiplier |
|---|---|
| Lose weight | 0.80 |
| Lose weight gradually | 0.90 |
| Maintain current weight | 1.00 |
| Gain weight gradually | 1.10 |
| Gain weight | 1.15 |
These settings correspond to:
20% calorie deficit for weight loss.
10% calorie deficit for gradual weight loss.
No adjustment for maintenance.
10% calorie surplus for gradual weight gain.
15% calorie surplus for weight gain.
For example, if your maintenance calories are 2,500 kcal:
A 20% deficit gives 2,000 kcal.
A 10% deficit gives 2,250 kcal.
Maintenance gives 2,500 kcal.
A 10% surplus gives 2,750 kcal.
A 15% surplus gives 2,875 kcal.
Step 7: Click Calculate
After entering your information, click the Calculate button.

How Does the Daily Calories Calculator Work?
Our daily calorie needs calculator uses several mathematical formulas.
Understanding these formulas helps explain how the results are determined.
1. Basal Metabolic Rate (BMR) Formula
Basal metabolic rate estimates the energy your body needs to maintain essential functions at rest.
These functions include breathing, blood circulation, temperature regulation, and cellular activity.
The calculator uses the Mifflin-St Jeor equation.
BMR Formula for Males
BMR = (10 × Weight in kg) + (6.25 × Height in cm) − (5 × Age) + 5
BMR Formula for Females
BMR = (10 × Weight in kg) + (6.25 × Height in cm) − (5 × Age) − 161
Example: Calculate BMR
Consider a 30-year-old male with:
Weight = 80 kg
Height = 180 cm
Age = 30 years
Using the formula:
BMR = (10 × 80) + (6.25 × 180) − (5 × 30) + 5
BMR = 800 + 1,125 − 150 + 5
BMR = 1,780 calories per day
This means the individual's estimated basal energy requirement is approximately 1,780 calories daily.
However, BMR does not represent the total calories burned during a normal day.
Physical activity and daily movement increase total energy expenditure.
2. Total Daily Energy Expenditure (TDEE) Formula
TDEE estimates the total calories your body uses during a typical day.
Our calculator determines TDEE by multiplying BMR by an activity factor.
Formula:
TDEE = BMR × Activity Multiplier
Using the previous example:
BMR = 1,780 kcal
Activity level = Moderately active
Activity multiplier = 1.55
TDEE = 1,780 × 1.55
TDEE = 2,759 calories per day
Therefore, the estimated maintenance calorie requirement is approximately 2,759 calories daily.
3. Recommended Daily Calories Formula
After calculating maintenance calories, the calculator adjusts the result according to your selected weight goal.
Formula:
Recommended Daily Calories = Maintenance Calories × Goal Multiplier
For example:
Maintenance calories = 2,759 kcal
Goal = Weight loss
Multiplier = 0.80
Recommended calories = 2,759 × 0.80
Recommended calories = 2,207.2
Recommended daily calories = 2,207 kcal
The calculator rounds the final target to the nearest whole calorie.
4. Daily Calorie Adjustment Formula
The daily calorie adjustment shows the difference between your recommended calorie target and your estimated maintenance requirement.
Formula:
Daily Calorie Adjustment = Recommended Daily Calories − Maintenance Calories
Using our example:
Daily adjustment = 2,207 − 2,759
Daily calorie adjustment = -552 kcal
A negative number indicates a calorie deficit.
A positive number indicates a calorie surplus.
A result near zero indicates maintenance.
5. Estimated Weekly Weight Change Formula
The calculator estimates weekly weight change using a simplified energy-balance model.
It assumes approximately 7,700 calories correspond to one kilogram of body-weight change.
Formula:
Estimated Weekly Weight Change (kg) = (Daily Calorie Adjustment × 7) ÷ 7,700
For example:
Daily calorie deficit = 552 kcal
Weekly deficit = 552 × 7
Weekly deficit = 3,864 kcal
Estimated weekly weight loss = 3,864 ÷ 7,700
Estimated weekly weight loss = approximately 0.50 kg
To convert kilograms into pounds:
Weight change (lb) = Weight change (kg) × 2.20462262
0.50 × 2.20462262 ≈ 1.10 lb
Therefore, the calculator would estimate approximately 0.50 kg or 1.10 lb of weight loss per week.
Important: This is a simplified mathematical estimate.
Actual weight changes are not perfectly linear because energy expenditure, body composition, fluid balance, and metabolism can change over time.
6. Body Mass Index (BMI) Formula
The calculator also calculates your Body Mass Index.
BMI is a screening measurement that compares body weight with height.
Formula:
BMI = Weight (kg) ÷ Height (m)²
For example:
Weight = 80 kg
Height = 180 cm = 1.80 m
BMI = 80 ÷ (1.80 × 1.80)
BMI = 80 ÷ 3.24
BMI = 24.7
This falls within the standard adult healthy-weight BMI category.
7. Calories Per Meal Formula
The calculator provides two meal-planning estimates.
Three Meals Per Day
Calories Per Meal = Recommended Daily Calories ÷ 3
For a 2,400-calorie target:
2,400 ÷ 3 = 800 calories per meal.
Four Meals Per Day
Calories Per Meal = Recommended Daily Calories ÷ 4
For the same calorie target:
2,400 ÷ 4 = 600 calories per meal.
These results assume an equal calorie distribution across meals.
You can distribute calories differently according to your hunger, schedule, and preferences.
Complete Daily Calories Calculator Example
Consider a person with the following information:
| Input | Value |
|---|---|
| Age | 30 years |
| Biological sex | Male |
| Weight | 80 kg |
| Height | 180 cm |
| Activity level | Moderately active |
| Weight goal | Lose weight |
| Selected deficit | 20% |
Step 1: Calculate BMR
BMR = 1,780 kcal/day
Step 2: Calculate Maintenance Calories
Maintenance = 1,780 × 1.55
Maintenance = 2,759 kcal/day
Step 3: Calculate Recommended Calories
Recommended calories = 2,759 × 0.80
Recommended calories = 2,207 kcal/day
Step 4: Calculate Daily Calorie Adjustment
Adjustment = 2,207 − 2,759
Adjustment = -552 kcal/day
Step 5: Estimate Weekly Weight Change
Weekly weight change = (-552 × 7) ÷ 7,700
Weekly change ≈ -0.50 kg
This is approximately 1.11 pounds per week when calculated using the underlying unrounded value.
Step 6: Calculate BMI
BMI = 80 ÷ 1.8²
BMI = 24.7
BMI category = Healthy weight
Step 7: Calculate Calories Per Meal
Three meals:
2,207 ÷ 3 ≈ 736 kcal
Four meals:
2,207 ÷ 4 ≈ 552 kcal
Final Calculator Results
| Result | Estimated Value |
|---|---|
| Recommended daily calories | 2,207 kcal |
| BMR | 1,780 kcal |
| Maintenance calories | 2,759 kcal |
| Daily calorie adjustment | -552 kcal |
| Estimated weekly weight change | Loss of 0.50 kg (1.11 lb) |
| BMI | 24.7 |
| BMI category | Healthy weight |
| Calories per meal (3 meals) | 736 kcal |
| Calories per meal (4 meals) | 552 kcal |
These results provide a starting point for understanding daily energy requirements and weight-management goals.
Understanding Your Daily Calorie Calculator Results
After completing the calculation, you will see several important values.
Recommended Daily Calories
This is the main result.
It represents your estimated calorie intake based on your selected weight goal.
If you select weight loss, the calculator recommends fewer calories than maintenance.
If you select weight gain, the recommendation is higher.
For maintenance, the recommendation matches estimated TDEE.
Basal Metabolic Rate (BMR)
BMR represents estimated resting energy expenditure.
It is not the same as your daily calorie requirement because your body uses additional energy during normal activities.
Maintenance Calories (TDEE)
Maintenance calories represent your estimated total daily energy expenditure.
This value is useful when deciding how much to eat to maintain, lose, or gain weight.
Daily Calorie Adjustment
This result shows your estimated calorie deficit or surplus.
For example:
-500 kcal/day indicates a deficit.
+300 kcal/day indicates a surplus.
0 kcal/day indicates no planned adjustment.
Estimated Weekly Weight Change
The calculator uses your daily calorie difference to estimate weekly weight change.
A deficit produces an estimated loss.
A surplus produces an estimated gain.
The result is displayed in both kilograms and pounds.
If the estimated absolute weekly change is less than 0.01 kg, the calculator displays "Approximately stable."
BMI and BMI Category
BMI provides a general weight-for-height screening measurement.
The calculator categorizes your result using standard adult BMI thresholds.
Calories Per Meal
The calculator divides your recommended daily calorie target into either three or four equal portions.
This can help simplify meal planning.
However, you are not required to consume equal calories at every meal.
BMI Categories Explained
The calculator uses the following adult BMI categories.
| BMI | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 to below 25 | Healthy weight |
| 25 to below 30 | Overweight |
| 30 or higher | Obesity range |
For example, a BMI of 22.5 is categorized as healthy weight.
A BMI of 27.0 is categorized as overweight.
A BMI of 31.5 falls within the obesity range.
BMI can be useful for general screening, but it does not directly measure body fat.
Athletes with substantial muscle mass may have a higher BMI without having unusually high body fat.
Similarly, a person with a BMI in the healthy range may still have other health risks.
BMI should be considered alongside additional information rather than used as a complete assessment of health.
How Many Calories Should You Eat to Lose Weight?
Your weight-loss calorie target depends on your estimated maintenance requirement.
Our calculator offers two options.
20% Calorie Deficit
This option reduces your estimated maintenance calories by 20%.
For example:
Maintenance calories = 2,500 kcal
Weight-loss calories = 2,500 × 0.80
Daily target = 2,000 kcal
Estimated daily deficit = 500 kcal.
Estimated weekly deficit = 3,500 kcal.
Using the calculator's simplified model:
Estimated weekly loss = 3,500 ÷ 7,700
Estimated loss = 0.45 kg per week
10% Calorie Deficit
This option reduces maintenance calories by 10%.
For example:
Maintenance calories = 2,500 kcal
Target = 2,500 × 0.90
Daily target = 2,250 kcal
Estimated daily deficit = 250 kcal.
Estimated weekly deficit = 1,750 kcal.
Estimated weekly loss = 1,750 ÷ 7,700
Estimated loss = 0.23 kg per week
A smaller deficit may be easier to maintain and may better support exercise performance and recovery.
Actual results can differ from these estimates.
How Many Calories Should You Eat to Gain Weight?
Weight gain generally requires consuming more calories than your body expends.
Our calculator provides two weight-gain options.
Gradual Weight Gain: 10% Surplus
Suppose your maintenance requirement is 2,600 calories.
Recommended calories = 2,600 × 1.10
Recommended intake = 2,860 calories
Daily surplus = 260 calories.
Estimated weekly surplus = 1,820 calories.
Estimated weekly gain = 1,820 ÷ 7,700
Estimated gain = 0.24 kg per week
Weight Gain: 15% Surplus
Using the same maintenance requirement:
Recommended calories = 2,600 × 1.15
Recommended intake = 2,990 calories
Daily surplus = 390 calories.
Estimated weekly surplus = 2,730 calories.
Estimated weekly gain = 2,730 ÷ 7,700
Estimated gain = 0.35 kg per week
These calculations estimate total body-weight change, not muscle gain specifically.
If your goal is building muscle, resistance training, adequate protein, and sufficient sleep are important.
Daily Calorie Requirements by Activity Level
The following table shows estimated maintenance calories for different BMR values and activity levels.
| BMR | Sedentary | Lightly Active | Moderately Active | Very Active | Extra Active |
|---|---|---|---|---|---|
| 1,300 | 1,560 | 1,788 | 2,015 | 2,243 | 2,470 |
| 1,500 | 1,800 | 2,063 | 2,325 | 2,588 | 2,850 |
| 1,700 | 2,040 | 2,338 | 2,635 | 2,933 | 3,230 |
| 1,900 | 2,280 | 2,613 | 2,945 | 3,278 | 3,610 |
| 2,100 | 2,520 | 2,888 | 3,255 | 3,623 | 3,990 |
These values illustrate how activity influences daily calorie requirements.
They are examples rather than personalized recommendations.
How to Divide Your Daily Calories Across Meals
Meal planning can be easier when you have an approximate calorie budget for each meal.
Our calculator provides equal allocations for three or four meals daily.
For example:
| Daily Calories | 3 Meals Per Day | 4 Meals Per Day |
|---|---|---|
| 1,500 | 500 kcal | 375 kcal |
| 1,800 | 600 kcal | 450 kcal |
| 2,000 | 667 kcal | 500 kcal |
| 2,200 | 733 kcal | 550 kcal |
| 2,400 | 800 kcal | 600 kcal |
| 2,800 | 933 kcal | 700 kcal |
| 3,000 | 1,000 kcal | 750 kcal |
You can also distribute calories unevenly.
For example, someone with a 2,000-calorie target might prefer:
Breakfast = 400 kcal
Lunch = 600 kcal
Dinner = 700 kcal
Snacks = 300 kcal
Total = 2,000 kcal
The most useful meal schedule is one that supports your nutritional needs and can be maintained consistently.
Factors That Affect Daily Calorie Needs
Several factors influence how many calories your body burns.
Age
Resting energy expenditure often changes with age, partly because of changes in body composition and activity.
Body Weight
Larger bodies generally require more energy to maintain and move, although body composition matters.
Height
Height contributes to estimated energy requirements and is included in the Mifflin-St Jeor equation.
Biological Sex
The calculator uses sex-based BMR equations.
Individual calorie needs can still vary considerably within each category.
Physical Activity
Exercise, occupational movement, walking, and everyday activities contribute to energy expenditure.
Muscle Mass
Lean body mass is an important factor in resting energy expenditure.
People with greater muscle mass may have different energy requirements than people of similar weight with less muscle.
Health and Hormonal Factors
Certain medical conditions, medications, and hormonal changes can influence appetite, body weight, or energy expenditure.
A general calorie calculator cannot account for every individual circumstance.
Common Mistakes When Calculating Daily Calories
1. Selecting an Unrealistic Activity Level
Choosing an activity multiplier that is too high can overestimate your maintenance calories.
Use your typical weekly routine as a guide.
2. Confusing BMR With TDEE
BMR represents resting energy expenditure.
TDEE represents estimated total daily energy expenditure.
TDEE is generally the more useful starting point for determining a maintenance calorie target.
3. Choosing an Excessive Calorie Deficit
A larger deficit is not always better.
Very restrictive calorie targets can make it difficult to meet nutritional needs and maintain energy levels.
4. Expecting Identical Weekly Results
Body weight can fluctuate because of water retention, sodium intake, digestion, and other factors.
The calculator's weekly change estimate is not a guaranteed outcome.
5. Ignoring Food Quality
Calories are important for energy balance, but overall nutrition also matters.
A healthy eating pattern should provide adequate protein, dietary fats, carbohydrates, fiber, vitamins, and minerals.
6. Not Updating Your Calorie Needs
Energy requirements can change when your weight or activity level changes.
Recalculate your targets periodically to keep your estimates relevant.
Tips for Managing Your Daily Calorie Intake
Once you know your estimated calorie target, practical habits can help you follow it.
Choose meals that include a variety of nutrient-rich foods.
Include protein sources such as eggs, fish, poultry, dairy products, beans, lentils, or tofu.
Eat vegetables and fruits regularly to support fiber and micronutrient intake.
Choose dietary fats from foods such as nuts, seeds, olive oil, and fatty fish.
Pay attention to portion sizes, particularly for foods that are energy-dense.
If you are trying to lose weight, monitor progress over several weeks rather than focusing on a single day's measurements.
If you are trying to gain weight, consider gradually increasing food intake while monitoring your progress.
Remember that consistency matters more than achieving an exact calorie number every day.
Limitations of the Daily Calories Calculator
Although the calculator provides useful estimates, several limitations should be considered.
Calorie Calculations Are Estimates
The Mifflin-St Jeor equation predicts resting energy expenditure using general population relationships.
Actual metabolism may differ.
Activity Multipliers Are Approximate
The calculator uses standard activity factors rather than directly measuring your calorie expenditure.
Your actual TDEE may be higher or lower.
Weekly Weight Change Is Simplified
The calculator uses a fixed conversion of 7,700 calories per kilogram.
Real-world weight changes are affected by changes in body composition, fluid balance, metabolism, and activity.
Therefore, the estimated weekly weight change should not be treated as a guaranteed prediction.
BMI Does Not Measure Body Fat Directly
BMI compares weight with height.
It does not distinguish fat mass from muscle mass or account for fat distribution.
The Calculator Does Not Enforce Individualized Minimum Calories
The calculator checks that the recommended calorie target is positive, but it does not assess whether the result is nutritionally adequate.
Very low calorie recommendations may be inappropriate even when the calculation is mathematically valid.
Intended for Adults
The calculator accepts users aged 18–120.
It is not designed for children or adolescents younger than 18.
People who are pregnant, breastfeeding, managing certain medical conditions, or recovering from eating disorders should seek personalized advice from a qualified healthcare professional.
Frequently Asked Questions (FAQs)
1. What is a Daily Calories Calculator?
A Daily Calories Calculator estimates how many calories your body needs each day based on your age, biological sex, weight, height, activity level, and weight goal.
It can help you estimate maintenance calories and establish starting targets for weight loss or weight gain.
2. How many calories should I eat per day?
Your daily calorie requirement depends on your body measurements and activity level.
For example, someone with a BMR of 1,600 calories and an activity multiplier of 1.55 has estimated maintenance calories of:
1,600 × 1.55 = 2,480 kcal/day.
Your selected weight goal determines whether your recommended intake is above or below this amount.
3. How do I calculate my maintenance calories?
First, estimate your BMR using the Mifflin-St Jeor equation.
Then multiply your BMR by an activity factor.
For example:
BMR = 1,700 kcal
Activity multiplier = 1.375
Maintenance calories = 1,700 × 1.375
Maintenance calories = approximately 2,338 kcal/day.
4. How many calories should I eat to lose weight?
A calorie deficit is generally required for weight loss.
Our calculator offers deficits of 10% and 20% below estimated maintenance calories.
For example, someone maintaining weight at 2,500 calories would receive targets of 2,250 or 2,000 calories, depending on the selected option.
The most suitable deficit depends on individual health and nutritional needs.
5. How many calories should I eat to gain weight?
Weight gain generally requires a calorie surplus.
Our calculator offers 10% and 15% surplus options.
If your maintenance requirement is 2,400 calories, a 10% surplus produces a recommended intake of 2,640 calories daily.
6. What is the difference between BMR and TDEE?
BMR estimates the energy required for essential bodily functions at rest.
TDEE estimates total daily energy expenditure, including normal activity.
TDEE is generally the more relevant estimate when determining maintenance calorie intake.
7. Does the calculator estimate weekly weight loss?
Yes.
The calculator uses your daily calorie deficit or surplus to estimate weekly weight change.
It applies a simplified conversion of approximately 7,700 calories per kilogram.
The result is displayed in kilograms and pounds.
Actual weight change may differ substantially from this estimate.
8. Can I calculate daily calories using pounds and inches?
Yes.
The calculator supports kilograms and pounds for weight.
For height, it accepts centimeters, decimal feet, and inches.
Measurements are automatically converted into the units required for the calculations.
9. Why does the calculator show BMI?
BMI provides a general weight-for-height screening measurement.
The calculator uses your weight and height to calculate BMI and assign a standard adult category.
However, BMI does not directly measure body fat or provide a complete assessment of health.
10. How often should I recalculate my daily calorie needs?
Recalculate your calorie requirements whenever your body weight, physical activity, or weight-management goal changes significantly.
You can also reassess your estimates after several weeks of consistent tracking.
Adjustments may be useful if your actual weight trend differs from what the calculator predicts.
