Maintenance Energy Requirement (MER) Formula:
From: | To: |
The Maintenance Energy Requirement (MER) for weight loss calculates the daily caloric intake needed for a cat to safely lose weight. It's typically set at 80% of the maintenance calories for the cat's ideal weight.
The calculator uses the MER formula for weight loss:
Where:
Explanation: The equation accounts for the non-linear relationship between weight and metabolic rate in cats.
Details: Proper caloric restriction is crucial for safe feline weight loss. Too rapid weight loss can cause hepatic lipidosis (fatty liver disease), while insufficient restriction won't achieve weight loss.
Tips: Enter the cat's ideal weight in kilograms. For most domestic cats, this is typically between 3.5-5 kg, but consult your veterinarian for your cat's specific ideal weight.
Q1: How fast should a cat lose weight?
A: Aim for 1-2% of body weight per week. Rapid weight loss (>3% per week) can be dangerous.
Q2: Should I adjust calories as my cat loses weight?
A: Yes, recalculate periodically as your cat approaches its ideal weight.
Q3: What if my cat isn't losing weight on these calories?
A: Consult your vet. Some cats may need further calorie restriction (but never below 60% of maintenance).
Q4: Are there special diets for feline weight loss?
A: High-protein, low-carb diets often work best for cats while maintaining lean muscle mass.
Q5: How often should I weigh my cat during weight loss?
A: Weekly weigh-ins are ideal to monitor progress and adjust calories as needed.
