Why You Should Trust Us
Over the last year, we’ve reviewed over 80 cat food brands, including most of the biggest brands on the planet. We’ve read customer reviews, spoken with market insiders, and tested foods hands-on.
Based on that research, we’re bringing you an updated list of the best cat food brands and products in the industry. The following foods earn their place with outstanding ingredient quality, nutritional merits, and safety records.
Here’s How To Pick The Best Cat Food For Overweight Cats
Before we jump into the reviews, let’s talk more about the qualities of the best cat food for overweight cats.
The ideal weight loss diet has high protein content with moderate fat levels and minimal carbohydrates.
In general, if your cat is overweight, he may have been eating the wrong food for a long time. For overweight cats, just switching to a species-appropriate diet is often enough to make a difference. This type of diet helps to prevent obesity, and the transition alone may be enough to help your cat shed some extra pounds.
A species-appropriate diet mimics the nutritional content of your cat’s prey.
It’s rich in the right amino acids, contains low-to-moderate levels of animal-derived fat, and has little to no starch. This macronutrient distribution is at the heart of every good cat food. It helps cats maintain lean muscle mass, achieve appropriate blood sugar levels, and experience overall wellbeing.
Wet cat food is ideal for weight control.
Most overweight or obese cats live on dry cat food, which leaves them under-stimulated, over-sugared, and at risk for serious health conditions.
In contrast to kibble, high-moisture cat food is bulkier and will help your cat feel full for longer, even if he’s eating fewer calories. Think of it as a bowl of grapes versus a handful of raisins. You’ll get fewer calories in the bowl of grapes, but it feels more substantial and will leave you full for longer.
The switch to wet food might be a challenge, especially if your cat has eaten kibble since he was a kitten. But in the long run, it’s the best option to support your cat’s healthy body weight.
Free feeding is out for overweight cats.
Allowing your cat to freely nibble from a full bowl of food might seem to honor his natural instincts, but few things could be less natural for a cat. Cats naturally eat multiple small meals throughout the day, fasting between each successful hunt.
In addition to discouraging your cat from gorging himself, feeding multiple meals during the day will allow you to closely monitor your cat’s calorie intake.
There’s no need to choose a diet marketed for weight management.
Most indoor-specific recipes and diet cat foods follow a similar blueprint. They decrease the protein and fat while bumping up levels of carbohydrates and fiber. Foods with high carb and fiber content promise to keep your cat satisfied on roughage alone, but they fail to honor your cat’s needs as a carnivore.
As a bright spot, these diets are formulated to meet your cat’s minimal nutritional requirements with fewer calories. Also, some of these diets have a high protein content with minimal carbohydrates.
However, given the blueprint mentioned above, weight loss diets for cats are generally engineered for disappointment.
By restricting protein intake, these diets may cause muscle loss.
Secondly, because your cat is an obligate carnivore, he’s hardwired to feel satisfied by protein and fat—not carbohydrates or fiber. This means that while these diets are low-calorie, they’re not as satisfying as diets that are rich in the protein and fat that your cat instinctively craves.

To help your cat lose weight while maintaining healthy muscle mass, put his carnivorous needs first.
From his claws to his metabolism, your cat’s body is optimized to hunt and eat animals. That doesn’t change if he’s overweight, obese, or underweight.

How Much Food Should You Give Your Overweight Cat To Lose Weight?
My vet is recommending a therapeutic diet. Does my cat really need a special food?
Not necessarily. Prescription diets from brands like Royal Canin, Purina, and Hill’s Science Diet aren’t always all they’re cracked up to be.
These brands make heavy use of carbohydrates and non-nutritive fillers your cat would be better off without. These low-fat foods may be lower in calories than the average cat food, but in exchange for a reduced calorie content you’re also compromising the quality of your cat’s diet. Your cat needs natural, whole-food ingredients that deliver real nutrients he can absorb and utilize.
Simply put, it’s better to stick with a high-quality cat food and promote weight loss by reducing your cat’s daily portion and increasing his activity level.
Your cat should lose weight at a slow, steady rate of about 1-2% of his current weight each week. For example, if your cat currently weighs 25 lbs., he should lose between 4 and 8 ounces during his first week of dieting.
You probably won’t notice such a small rate of weight loss from week to week. But slow and steady weight loss is preferable to rapid weight loss. Your cat is more likely to maintain the weight loss if it is done gradually.
Three Ways to Calculate Your Overweight Cat’s Calorie Needs
- The 80% Technique
Assuming your cat is currently maintaining an unhealthy body weight, determine the number of calories he eats now and gradually cut back to 60-80% of that amount.
If you don’t know how much your cat presently eats, consult with your vet or try one of the other two methods.
- The Crystal Ball Method
The following formula will give you an estimate of your cat’s maintenance calorie intake at an ideal weight. The variable “W” represents your cat’s weight in pounds.
(13.6 x W) + 70 = Calories required to maintain your cat’s ideal weight
If your cat’s ideal weight is 11 lbs., then his maintenance intake will be roughly 220 calories per day. When your cat is eating for a slimmer body, he’s living with a calorie deficit. This encourages gradual weight loss until your cat reaches his goal weight.
- The Intuition Approach
If you’re not someone who likes numbers and rules and calculations, you’ll probably prefer a common-sense approach to weight loss. Just feed your cat less until he’s reached a healthy weight.
Remember that a highly satisfying, moisture-rich, high-protein pet food will help you out here.
Keep this in mind, though: Cutting calories with your cat’s current diet could also reduce his nutrient intake. Your cat’s weight loss should be not come at the expense of his nutritional needs.
Your vet will be able to provide you with the most accurate calorie counts that your cat will need to achieve a healthy weight.

Unlike the majority of indoor foods—which sacrifice species-appropriateness in the name of preventing hairballs and weight gain—this food is a meaty, protein-packed product.

On the negative side, this food isn’t made with animal protein alone. In addition to an array of meat ingredients, the food contains pea protein and dried ground peas. While they won’t hurt, these plant protein sources aren’t ideal for an obligate carnivore like your cat.

With The Right Food And A Solid Strategy, You Can Help Your Cat Reach A Healthy Weight.
Weight loss isn’t an arcane pursuit. Once you’ve established a strong strategy and chosen a nutritious diet, your biggest challenge will be to stay disciplined and consistent.
Especially if you’re converting your cat from dry food to wet cat food, you’re bound to encounter some frustrations along the way. There will be days when you want to give in to your cat’s meows and give up altogether. When you feel like you’re hitting a wall, take a deep breath and remember that a healthier, happier cat is waiting on the other side.
Track your cat’s weight loss from week to week. Also, talk to your veterinarian about your cat’s weight loss. If your cat’s weight has plateaued, your vet might recommend trying a different food or adding in extra exercise to stimulate weight loss.
Regarding exercise, physical activity is a critical component of weight loss. In combination with fewer calories from the new diet, physical activity will help increase your cat’s metabolism, helping your cat burn more calories.
Frequently Asked Questions
What is the best cat food for losing weight?
The best cat food for weight loss isn’t necessarily a prescription diet from brands like Purina or Royal Canin. In fact, you can help your cat lose weight on just about any food as long as it is nutritionally balanced and you control the portions. If you want to know about the best cat food for weight loss, however, we recommend a high-protein, low-carbohydrate wet food with moderate fat and calorie content.
How do I get my indoor cat to lose weight?
Indoor cats tend to be less active than outdoor cats, so cat owners may need to be more proactive when it comes to helping indoor cats lose weight. The first step is to choose a diet that supports your cat’s weight loss and determine the appropriate number of calories per day. On top of adjusting your cat’s diet, you should also make an effort to increase his activity level with daily play sessions.
Is wet or dry cat food better for weight loss?
Generally speaking, you can help your cat lose weight using either dry food or wet food. That being said, wet food tends to be the better option because it is higher in protein and moisture which make it more satisfying for your cat – you can feed less without your cat feeling deprived.
