The manufacturer recommends this food for all adult cats who are less active and, therefore, prone to weight gain. The only drawback of this Hill’s Science Diet recipe is that you can’t give it to kittens, pregnant, or nursing felines.

Also, your feline needs to have access to clean, fresh water, even though cat food manufacturers insist their canned products have enough moisture inside.
So, for adult cats of 6-8 pounds, feed 2 ½ – 3 cans daily. When feeding a kitten, give up to 2 ½ times this amount. If your cat is pregnant or nursing, allow her free access to food.

Essential Things to Keep in Mind
Overfeeding is among the top causes of obesity in cats, and that is why some vets don’t recommend free-feeding (that’s when food is available to your feline 24/7). Having an indoor cat who is not so active, it’s better to control how much food she eats, especially if you start noticing her overeating.
Some medical conditions may predispose our felines to obesity too, so make sure to visit a vet regularly. And given that obesity is more common in older cats (that’s because of their natural decrease in exercise), please tailor a cat’s diet to her lifestyle and age.
Remember about the health risks for your overweight cat: diabetes, high blood pressure, liver disease, heart disease, arthritis, and even cancer. The cuteness of a fatty kitty isn’t worth these troubles, don’t you agree? So let’s be responsible owners and help our felines deal with overweight if they get any.
And when looking for healthy cat food for weight loss, please pay attention to its macronutrient ratio, aka the balance of protein, fat, and carbohydrates.
For cats on a diet, choose food with minimum carbohydrates. They aren’t necessarily bad, but that’s not what a cat needs when trying to deal with being overweight. Focus on protein and fat sources in the food, as they are vital to cat health, and look for low-carb cat food that’s rich in proteins.
The low-fat cat food brands I reviewed above in this article are good options to consider. Check the best weight loss cat food with more than 30% of the protein inside.
And last but not least:
When your cat is on a diet, please keep an eye on her to make sure she eats diet food. Starvation is not the option, as it may lead to hepatic lipidosis, a liver disease overweight felines can get when they start eating too little suddenly. Even when on a diet, a cat needs to get all the essential nutrients.
How to Place a Cat on a Diet Right
We love our cats, no matter how fatty and fluffy they are. And yet, we understand the problem of obesity in felines. So once we start suspecting that our four-legged friend becomes overweight, it may be high time to place her on a diet.
But how to do that right so as not to hurt a cat, her health, and overall wellbeing?
First of all, please visit a veterinarian to make sure your feline is overweight and needs cat diet food. Don’t take any drastic measures yourself: A specialist will see the health condition of your cat and will recommend some best food for fat cats.
After that, when a cat food for weight loss is in your pocket, it’s time to put a cat on a diet, step by step. Believe me, it can be harder than you think, especially when a feline gets used to one particular food, and now she’s forced to eat a different one.
These steps can help you cope with the challenge.
Step 1: Figure Out How Many Calories Your Cat Needs for Weight Loss
First of all, ask a vet about the ideal weight for your cat and how many calories she needs per day when in it. For losing weight, cats need to eat 75-80% of their daily norm. Drawing from these numbers, you can estimate how many calories to give to your cat so she would start losing weight.
Let’s say your cat’s ideal weight is 5-8 pounds, and she needs to take between 24 to 35 calories a day per pound to stay healthy. So we have 8×35=280kcal per day, which means that our cat needs 280 – 20% = 224kcal daily to start losing weight.
The approximate amounts are:
- 180 kcal/day for an ideal weight of eight pounds
- 210 kcal/day for a weight of ten pounds
- 230 calories/day for a weight of twelve pounds
All the best diet food for cats has feeding recommendations and provides customers with a number of calories per cup or can, so you will easily estimate how much food to give. Also you can use our guide about how much should your cat eat.
Step 2: Limit Her Access to Food
Say no to free-feeding when your cat is on a diet. You shouldn’t let a feline get unlimited access to her food. Put a portion down for 15-20 minutes, and then pick it back even if she hasn’t eaten it all. It will help you see how much food she eats exactly.
Try providing a cat with smaller portions but more frequently. Divide her diet food into three or four servings a day: It will help her stay well-fed, and she will not meow all the time, asking for food.
Step 3: Change Her Regular Food for a Diet Cat Food Gradually
If your cat refuses to eat a new diet cat food, please don’t force her. Start with adding a small amount to her regular meal, and then transit to a diet food gradually over 7-10 days. It will help your cat get used to new food intake and avoid problems with digestion.
Another point to consider:
No matter if you choose dry or wet cat food for weight loss, make sure your feline has access to fresh and clean water all the time. Therefore, you’ll minimize her overeating: often, cats feel hungry and eat when they are just thirsty.

Step 4: Work on Changing Her Behavior and Weigh a Cat Weekly
It stands to reason that an active cat burns more calories and loses weight more effectively than a cat with no exercising or playing games. So, entertain your feline, spend more time playing with her, and motivate her to move more. Exercises will reduce her appetite and improve metabolism so that she will lose weight faster.
Weigh your cat and record her weight every week. It will help you and your vet see the progress and correct a cat diet for further results.
The Most Common FAQ’s About Cat Food for Weight Loss
What should I feed my cat to lose weight?
First and foremost, visit a veterinarian so he could check your cat’s health and tell you a reason for her overweight. Together with the specialist, you will develop a diet for your cat to lose weight but still get all the essential nutrients for her health. Your vet will recommend some low-fat cat food brands to you. Also, feel free to check the reviews of cat food for overweight cats (like this one you’re reading here) and choose both dry and wet options to feed your cat.
Is wet or dry cat food better for weight loss?
The best option would be to combine both dry and wet cat food for overweight cats, so your feline could get enough moisture and all the necessary elements of her diet. Feeding a cat with dry food only, you keep her out of the right amount of liquid. (Make sure your cat has free access to fresh and clean water!) And feeding with wet food only, you deny a cat the opportunity to vary her diet. Semi-moist cat food should also be a supplementary source of nutrients.
What is the best dry cat food for weight loss?
It depends on your cat’s weight, health conditions, and nutrition needs. The most popular one in the lists of best diet food for cats is Blue Buffalo Weight Control Natural Adult Dry Cat Food: They focus on real-meat ingredients and are low-calorie enough for a cat to lose weight with no harm to health. Alternatives to try might be Royal Canin Weight Care Dry Cat Food and Hill’s Science Diet Adult Perfect Weight Food: Both are even lower in calories than Buffalo Weight, but they have some nuances anyway. (Please check the reviews above.)
What is the healthiest cat food for weight loss?
If looking for the dry cat food for weight loss, pay attention to Nulo Grain-Free Dry Cat Food: 82% of proteins here come from real meat (duck, turkey, and chicken), it’s low in carbohydrates, and it’s rich in BC30 probiotics supporting healthy gut flora. For a wet cat diet food, consider PetGuard Weight Management Cat Food: low in calories but rich in vitamins and proteins, it suits cats of all ages and contains enough moisture for a cat’s needs.
How much wet food should I feed my cat for weight loss?
It depends on how many calories your cat needs to consume daily. For her to start losing weight, please feed 20% fewer calories than your feline needs when in her ideal weight, to provide caloric reduction. Let’s say her ideal weight is 6 pounds, and she needs 200 kcal to maintain it. Now, when she is overweight, you need to feed her 160 kcal (200 – 20%). So, check the calories of her wet food and feed accordingly.
How can I help my cat lose weight?
Buying weight-loss food for your cat is not enough. You should make sure that your cat eats the right amount of this food. An automatic cat feeder is a great option that will feed your cat the right portion every time. If you have several cats with different diets, you should separate them with RFID cat doors.
Also, your cat should be active enough. One of the best indoor solutions is a cat exercise wheel — highly recommend you to check it out.
In a Word
Obesity affects about 40% of felines, and it’s the most common nutritional disorder among domestic cats. Though some medical conditions can also lead to it, the main reason for obesity is overfeeding our four-legged friend with her favorite and, undoubtedly, solid food.
Yes, fluffy and fatty cats may look adorable; but, responsible cat owners understand that overweight is a big problem leading to major issues with health: diabetes, arthritis, high blood pressure, heart and liver disease, or even cancer. Understanding the gravity of the situation, we agree to put our cat on a diet and start giving low-calorie cat food to her so she could stay healthy.
With so much cat food for overweight cats on the market, please focus on protein-rich (no less than 30% of protein inside) but low-calorie recipes, both dry and wet, to organize and control a diet for your feline. I did my best to review ten best cat foods for weight loss and make weight loss cat food comparison here, so feel free to consider any of them for your fluffy friend.
But regardless of what cat diet food you choose, please consult with a vet specialist. Health conditions, age, lifestyle, and breed of our cat – all these influences a diet she needs for a positive outcome.
