Calorie Recommendations
Based on your calculated maintenance calories of 0 calories/day, here are recommendations for different goals:
Nutrition Tip: For sustainable weight loss, aim for a 500-calorie daily deficit (about 1 lb/week). For weight gain, aim for a 250-500 calorie surplus. Always prioritize protein intake and nutrient-dense foods.
Your Calculation History
What Are Calorie Maintenance Calculators?
Your calorie maintenance (or Total Daily Energy Expenditure – TDEE) is the number of calories you need to consume each day to maintain your current weight. It’s calculated based on your Basal Metabolic Rate (BMR) and activity level.
Key Insight: Knowing your calorie maintenance level is crucial for any weight management goal. Whether you want to lose, gain, or maintain weight, you need to know your starting point.
Our calorie calculators use scientifically validated formulas to estimate your energy needs without complicated measurements. They provide a solid foundation for creating effective nutrition plans.
Why Calculate Your Calorie Needs?
Set realistic calorie targets for weight loss or gain based on your individual metabolism and activity level.
Plan your daily meals and snacks with appropriate calorie amounts for your goals.
Monitor changes in your metabolism as you lose weight or gain muscle mass.
Ensure you’re eating enough to support your activity level and overall health.
How to Use the Calorie Calculators
Follow these simple steps to calculate your calorie needs:
- Select Calculator: Choose the calculator that matches your goal (TDEE, BMR, Weight Loss, etc.)
- Enter Personal Data: Input your age, gender, height, and weight
- Select Activity Level: Choose the option that best describes your daily activity and exercise
- Add Goal Details: For weight loss/gain calculators, specify your timeframe and target weight
- Calculate: Click “Calculate” to see your personalized results
- Save Results: Save your calculation to track progress over time
- Follow Recommendations: Use the calorie and macro recommendations to guide your nutrition
Pro Tip: For the most accurate results, measure your height and weight in the morning before eating or drinking. Update your calculations every 4-6 weeks or after significant weight changes.
Calculation Methods Explained
Women: (10 × weight) + (6.25 × height) – (5 × age) – 161
Most accurate for most people. Considered the gold standard for BMR calculation.
Women: 447.593 + (9.247 × weight) + (3.098 × height) – (4.330 × age)
Older but still accurate formula. Slightly less precise for obese individuals.
Multiplies your BMR by an activity factor (1.2-1.9) to account for daily movement and exercise.
Provides a general indicator of body fatness. Not perfect but useful for population-level assessment.
Understanding Activity Levels
Your activity level significantly impacts your calorie needs. Choose the level that best matches your daily routine:
Sedentary (1.2)
- Little or no exercise
- Desk job with minimal walking
- Mostly sitting throughout the day
- Example: Office worker with no regular exercise
Lightly Active (1.375)
- Light exercise 1-3 days per week
- Daily walking but no intense workouts
- Example: Retail worker who walks during shifts
Moderately Active (1.55)
- Moderate exercise 3-5 days per week
- Active job with some physical labor
- Example: Construction worker or regular gym-goer
Very Active (1.725)
- Hard exercise 6-7 days per week
- Physical job or training for sports
- Example: Athlete in training or manual laborer
Extra Active (1.9)
- Very hard daily exercise and physical job
- Training multiple times per day
- Example: Professional athlete or military personnel in training
Note: It’s better to underestimate your activity level than overestimate it. Most people fall into the sedentary or lightly active categories, even if they exercise regularly.
Nutrition Tips for Your Goals
Once you know your calorie targets, follow these evidence-based nutrition strategies:
For Weight Loss
- Prioritize Protein: Aim for 1.6-2.2g of protein per kg of body weight to preserve muscle mass
- Fill Up on Fiber: Eat plenty of vegetables, fruits, and whole grains to stay full
- Stay Hydrated: Drink water before meals and throughout the day
- Track Your Intake: Use a food diary or app to ensure you stay within your calorie target
For Weight Maintenance
- Listen to Hunger Cues: Eat when hungry, stop when satisfied
- Maintain Balance: Include all food groups in moderation
- Regular Weigh-ins: Weigh yourself weekly to catch trends early
- Adjust as Needed: Modify your intake if your weight drifts more than 2-3 pounds from your target
For Weight Gain
- Calorie-Dense Foods: Include healthy fats, nuts, seeds, and whole grains
- Protein Timing: Consume protein within 2 hours of strength training
- Resistance Training: Combine with calorie surplus to build muscle, not just fat
- Gradual Increase: Add 250-500 calories daily above maintenance for steady gain
Important: These calculators provide estimates. Individual calorie needs vary based on genetics, hormones, medications, and other factors. Consult with a healthcare professional or registered dietitian for personalized advice, especially if you have medical conditions.
Frequently Asked Questions (FAQ)
Calorie calculators are generally accurate within 10-15% for most people. Accuracy depends on honest reporting of activity level and accurate measurements. The Mifflin-St Jeor formula is about 80-90% accurate for predicting BMR in most populations.
Every 4-6 weeks or after significant weight change (±5-10 pounds). Your calorie needs decrease as you lose weight and increase if you gain muscle mass. Also recalculate if your activity level changes significantly.
BMR (Basal Metabolic Rate): Calories burned at complete rest for basic bodily functions.
TDEE (Total Daily Energy Expenditure): Total calories burned in a day, including BMR, activity, exercise, and food digestion (thermic effect of food). TDEE = BMR × Activity Multiplier.
Common reasons include: underestimating calorie intake, overestimating activity level, water retention, metabolic adaptation, or medical conditions. Track accurately for 2-3 weeks, then adjust if needed. Consider consulting a professional if plateau persists.
Generally not recommended without medical supervision. Very low calorie diets can cause nutrient deficiencies, muscle loss, metabolic slowdown, and other health issues. Sustainable weight loss is typically 0.5-1 kg (1-2 lbs) per week.
