How to put a Cat on a diet?

The program for weight loss in cats is multi-stage and includes the following steps:

  • Analysis by a veterinarian. It is best to consult your veterinarian before putting your pet on a diet since there are many health considerations. Your veterinarian will assess your cat and determine if there are any underlying diseases causing obesity or if your cat is at risk for any illnesses caused by obesity. They can then recommend the best foods for your cat. Rapid weight loss can affect the health, so the veterinarian will help you set the optimal program that is suitable for your animal. A cat with excess weight should not be abruptly transferred to a diet with a limited number of calories or lose weight too quickly. This can cause serious and even fatal hepatic lipidosis. 
  • Changing the diet. Choose the most appropriate product. Naturally, to reduce weight, you need to limit the number of calories. Most programs recommend giving the cat 75% of the calories it would need if it had the ideal weight. 

There are two ways to reduce the number of calories. The first is to give the cat less food. The second is to switch to a diet containing fewer calories.

Limit the amount of food. If your cat is losing weight according to the program that allows feeding it with regular food, its amount should be reduced by 20-40%. For example, if your furry friend usually eats 3/4 сup of dry food, you should now give it 1/2 cup. After 3-4 weeks, you should see positive results. You may have to cut the portions even more. Essential fatty acids are beneficial for any cat however, not just those on a weight loss program.  

If your cat has switched to a portion of best weight management food, you can save the standard part, but it contains less fat and calories. Some diets include carnitine, as it affects the body’s absorption of fat. Studies conducted on rats have shown that another chemical, pyruvate, fruitfully affects the metabolism of obese individuals and causes faster weight loss. It has a similar effect on people. Chromium picolinate encourages the body to produce insulin more actively. The effectiveness of its effect on weight loss in obese animals is currently being studied. The herbaceous plant Garcinia cambogia contains hydroxylimonic acid, which is considered a substance that prevents fat cells’ formation. Coenzyme Q10 (also known as ubiquinone) provides the body with energy at the cellular level. It is beneficial for people with various heart and muscle diseases, but its effect on animals suffering from obesity is still under study. Finally, as a supplement to the diet, chitin or chitosan, a substance that can inhibit fat absorption, is being investigated. [2] 

  • Сat it should be fed smaller, more frequent meals to make sure the cat stays full and doesn’t feel like it is starving. this will allow you to control the feeling of hunger. It is usually recommended to give 2-4 small portions of best low-calorie food during the day. Feed your fat pet separately from other animals so that it does not eat the other pet’s food. Usually, overweight cats are not as agile as others, so you can feed it on the floor, and others – at a higher level, for example, on the cat “tree.”
  • Physical exercise. In addition to reducing incoming calories, you also need to increase calories burned. It is more difficult for obese cats to develop an exercise program than for dogs. For some cats, walking on a harness is already a good exercise. Even a simple walk in the yard under your supervision can encourage the pet to move a little more. Buy some new toys and start playing with it. In addition to the fact that the game will help burn extra calories, it will also distract the cat from the food bowl.

Buying Guide

Cat foods aimed at weight loss usually have a lower energy value than other products of the same line. This is achieved by reducing fat percentage and including additional sources of fiber (indigestible fibers). The fibers swell in the stomach, providing the animal with a feeling of satiety, while they are removed from the body unchanged and practically do not give calories.


In high-quality food, fiber is usually represented by vegetables, root vegetables, unsweetened fruits, and other plants. When there are many fillers, they excessively irritate the intestines, cause digestive disorders, stool disorders, and prevent food absorption.


Sometimes special supplements are used in fitness feeds to normalize weight. For example, the introduction of L-carnitine allows you to limit fat deposition if we are talking about preventing obesity and preserving muscle mass in the process of losing weight.

Protein source

The protein content of food for weight control should be high (at least 32-35%). This contributes to rapid saturation, weight loss due to fat, and not the muscles and internal organs. Pay attention to the sources of protein: it should be meat and the entrails of animals.

When using food, it is essential to observe the daily dosages recommended by the manufacturer. If dry pellets are always in the bowl, and the cat continues to eat according to appetite, weight loss will not occur, despite the special diet. [3]
