Brit GF Veterinary Diet Obesity Cat, 400 g is a grain-free dietetic food from the Czech brand Brit for weight loss in obese cats and neutered cats prone to gaining weight. It's very high in protein — 43% (based on dehydrated chicken, 42% of the recipe) — so that fat rather than muscle is lost. Fat is low at 10%, and fibre is high at 6% thanks to bamboo lignocellulose and psyllium, which keep cats full on fewer calories. L-carnitine (600 mg per kg) supports fat metabolism, and chondroprotectors support joints burdened by extra weight. Energy: 348 kcal per 100 g.

Pros
- Very high protein. 43% helps preserve muscle during weight loss.
- Satiety. Lignocellulose and psyllium reduce begging.
- L-carnitine. 600 mg per kg for fat metabolism.
- Grain-free. A low glycaemic index.
- For joints. Chondroprotectors — extra weight loads the joints.
Cons and what to keep in mind
- A therapeutic diet. Prescribed by a vet and fed until target weight.
- Contraindications. Kittens, pregnant and nursing cats.
- Chicken-based. Not for cats with a chicken allergy.
- More stool. The fibre increases stool volume.
- Small pack. 400 g won't last long — a larger bag is better value for a course.
How a cat can lose weight safely
Rapid weight loss is dangerous for cats: fasting can trigger hepatic lipidosis. A safe pace is about 1–2% of body weight a week. The vet sets the target weight and daily amount; you weigh your cat weekly and record the result. Feed the food dry or softened with warm water, split into 3–4 meals, with fresh water always available. More in overweight cats and dogs.
More movement, fewer titbits
The diet works better with play: 2–3 sessions a day of 10–15 minutes with a wand toy, puzzle feeders and food hidden around the home. Everyone in the family must know not to feed extras — even a piece of sausage wipes out the day's plan. Play ideas in how to entertain a cat at home.
Obesity, Adipositas or Weight Control
For marked obesity, a vet chooses a therapeutic diet — Brit VD Obesity or, for example, Happy Cat VET Adipositas. Once the goal is reached, the cat moves to a weight-maintenance food such as Brit Care Sterilised Weight Control. On feeding after neutering, see caring for a cat after spaying.
How to tell the weight loss is on track
Good signs are gradual weight loss and a returning waist while the cat stays active, eats well and keeps playing. Bad signs are refusing food for more than a day, lethargy, vomiting or losing weight too fast. In those cases, see a vet straight away.
Who it suits
Adult obese and overweight cats and neutered cats prone to weight gain — as prescribed by a vet. Other foods are in dry cat food.
Verdict
Brit Veterinary Diet Obesity Cat is a strong grain-free weight-loss diet: 43% protein, low fat, plenty of fibre and L-carnitine. Weight loss on it should be slow and vet-supervised, followed by a switch to a maintenance food once the goal is reached.
