DER Equation:
| From: | To: |
The DER (Daily Energy Requirement) equation estimates the daily calorie needs for raw food diets based on body weight. It provides a scientific approach to determining appropriate calorie intake for maintaining optimal health with raw food nutrition.
The calculator uses the DER equation:
Where:
Explanation: The equation accounts for the non-linear relationship between body weight and metabolic rate, with adjustments for the specific energy requirements of raw food nutrition.
Details: Accurate DER estimation is crucial for maintaining proper nutrition on raw food diets, ensuring adequate calorie intake while avoiding overconsumption that could lead to weight gain.
Tips: Enter body weight in kilograms. The value must be valid (weight > 0). For best results, use your current accurate body weight measurement.
Q1: Why is the exponent 0.75 used in the formula?
A: The 0.75 exponent reflects the metabolic scaling relationship observed across mammalian species, where metabolic rate scales to the 3/4 power of body mass.
Q2: How does raw food affect calorie requirements?
A: Raw foods typically require more energy for digestion and may have different nutrient bioavailability, which is accounted for in the 1.8 activity factor.
Q3: Should this calculation be adjusted for activity level?
A: The 1.8 factor already includes a moderate activity level adjustment suitable for most people following raw food diets.
Q4: Are there limitations to this equation?
A: This calculation provides an estimate and may need individual adjustment based on metabolism, specific activity levels, and health conditions.
Q5: How often should I recalculate my DER?
A: Recalculate whenever your body weight changes significantly (more than 2-3 kg) or if your activity level changes substantially.
