1. What is the Weight Loss MER Calculation?

The weight loss MER (Maintenance Energy Requirement) calculation determines the appropriate calorie intake for pets that need to lose weight. It's typically set at 80% of the RER (Resting Energy Requirement).

2. How Does the Calculator Work?

The calculator uses the weight loss formula:

Where:

• \( MER \) — Maintenance Energy Requirement for weight loss (kcal/day)
• \( RER \) — Resting Energy Requirement (kcal/day)
• 0.8 — Weight loss factor (80% of RER)

Explanation: This reduced calorie intake helps pets lose weight gradually and safely while maintaining essential bodily functions.

3. Importance of Weight Loss Calories

Details: Proper calorie calculation is crucial for safe and effective weight loss in pets, preventing health issues associated with obesity while ensuring adequate nutrition.

4. Using the Calculator

Tips: Enter the pet's RER in kcal/day. The RER can be calculated using the formula: \( RER = 70 \times (body\ weight\ in\ kg)^{0.75} \).

5. Frequently Asked Questions (FAQ)

Q1: Why use 80% of RER for weight loss?
A: 80% of RER provides a safe calorie deficit that promotes gradual weight loss (1-2% of body weight per week) while maintaining health.

Q2: How often should I recalculate the MER?
A: Recalculate every 2-4 weeks or after every 10% change in body weight to adjust for metabolic changes.

Q3: Is this suitable for all pets?
A: While generally safe, pets with medical conditions may need customized plans. Always consult with a veterinarian.

Q4: What if my pet isn't losing weight?
A: If no weight loss after 4 weeks, you may reduce to 70% of RER, but only under veterinary supervision.

Q5: Can I use this for rapid weight loss?
A: No, rapid weight loss can be dangerous. This calculator provides safe, gradual weight loss calories.
