1. What is the Maintenance Calorie Calculator?

Definition: This calculator estimates how many calories your body needs daily to maintain your current weight, based on your Basal Metabolic Rate (BMR) and Physical Activity Level (PAL).

Purpose: It helps you understand your daily energy requirements, allowing you to make informed decisions about maintaining, losing, or gaining weight while ensuring proper nutrition.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor Equation—one of the most accurate methods—to calculate your BMR:

\[ \text{BMR (Male)} = 10 \times \text{weight (kg)} + 6.25 \times \text{height (cm)} - 5 \times \text{age (years)} + 5 \] \[ \text{BMR (Female)} = 10 \times \text{weight (kg)} + 6.25 \times \text{height (cm)} - 5 \times \text{age (years)} - 161 \]

Then, it multiplies your BMR by your PAL to estimate your Total Daily Energy Expenditure (TDEE), or maintenance calories:

\[ \text{Maintenance Calories} = \text{BMR} \times \text{PAL} \]

PAL options range from 1.2 (little or no exercise) to 2.4 (professional athlete), reflecting your typical activity level.

3. Why Would I Want to Know My Maintenance Calories?

Details: Knowing your maintenance calories helps you:

Make conscious food choices using nutrition labels.
Manage your weight effectively by setting a baseline.
Plan healthy weight loss or gain at a sustainable pace.
Ensure your body gets the energy it needs to function optimally.

Maintaining a healthy weight can also reduce risks of diseases like cardiovascular issues, diabetes, and some cancers.

4. Using the Maintenance Calorie Calculator

Tips: Enter your sex, age, weight, height, and activity level. The results show your BMR and maintenance calories. If your BMI is outside the healthy range, consider adjusting your calorie intake with professional guidance.

Frequently Asked Questions (FAQ)

How accurate is this calculator?

It uses the Mifflin-St Jeor formula, validated by research, but individual metabolism or health conditions may slightly alter results. Consult a doctor for personalized advice.

What’s the difference between BMR and maintenance calories?

BMR is the energy your body needs at rest. Maintenance calories (TDEE) include additional energy from your daily activities.

Can I use this if I’m not at a healthy weight?

Yes, but if your BMI is outside the healthy range, focus on adjusting your intake for weight loss or gain rather than maintenance.

How should I distribute my maintenance calories?

Follow USDA guidelines: 45-65% carbs, 20-35% fats, 10-35% protein, with less than 10% from saturated fats. Drink plenty of water!

What if I want to lose or gain weight?

For weight loss, reduce intake by 500-1000 kcal/day below maintenance. For weight gain, increase by 500-1000 kcal/day. Adjust gradually and seek professional advice.
