1. What is the Hills Weight Loss Equation?

The Hills weight loss equation calculates the Maintenance Energy Requirement (MER) for weight loss in pets. It provides a calorie target that promotes safe, gradual weight loss while maintaining lean body mass.

2. How Does the Calculator Work?

The calculator uses the Hills equation:

Where:

• \( ideal\_weight\_kg \) — The target ideal weight in kilograms
• 0.75 — The metabolic exponent
• 0.8 — The weight loss factor (80% of maintenance calories)

Explanation: The equation accounts for metabolic scaling with body weight and creates an appropriate calorie deficit for weight loss.

3. Importance of MER Calculation

Details: Accurate MER calculation is crucial for safe weight loss programs, preventing excessive calorie restriction while still promoting fat loss.

4. Using the Calculator

Tips: Enter the pet's ideal weight in kilograms. The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: Why use 80% of maintenance calories?
A: This creates a moderate calorie deficit that promotes gradual, sustainable weight loss while minimizing muscle loss.

Q2: How often should MER be recalculated?
A: Recalculate every 2-4 weeks as weight changes, or if the pet's activity level changes significantly.

Q3: What if my pet isn't losing weight at this calorie level?
A: Consult with a veterinarian before further reducing calories, as individual needs may vary.

Q4: Are there limitations to this equation?
A: Less accurate for very small or very large animals, and for pets with significant metabolic disorders.

Q5: Should this be adjusted for activity level?
A: This is a baseline calculation. Active pets may need slightly more calories, while sedentary pets may need slightly less.
