Low-carbohydrate diets for diabetic pets: what actually matters

"Low-carb" gets talked about a lot in pet diabetes — sometimes as if it's a magic fix. It's genuinely powerful, especially for cats, but it helps to understand what it really means and where it applies.

Why does carbohydrate matter?

Carbohydrate is the nutrient that raises blood glucose most after a meal. For a body that already struggles to manage glucose, reducing the carbohydrate load makes control easier. That's the whole logic — fewer big glucose spikes for the insulin to chase.

Why is it more important for cats than dogs?

Cats are obligate carnivores, built to run on protein and fat, not carbohydrate. A low-carbohydrate, higher-protein diet suits their physiology, improves glucose control, and gives the best chance of remission. Dogs are different: for them, consistency and moderate complex carbohydrate with good fibre generally matter more than driving carbs very low. So "low-carb" is a headline for cats and a smaller part of the picture for dogs.

What does a low-carb diet look like in practice?

For cats, that often means a low-carbohydrate wet food, since dry kibble usually needs starch to hold together. The exact food should come from your vet, matched to your cat. What matters as much as the food itself is feeding it consistently — same food, same amounts, same times.

How do I change diet safely?

Carefully and never suddenly. Because a new diet changes how much insulin your pet needs, a diet switch must be planned with your vet, who may adjust the dose at the same time. Changing food without adjusting insulin is one of the more common ways control slips.

Mello lets you log the food change alongside glucose readings, so you and your vet can see the effect clearly.
