Top Picks Explained
Here’s How To Pick 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, they might 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 well-being.
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 they are 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 they were 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 be the kindest choice, 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, feeding multiple meals during the day will allow you to closely monitor your cat’s calorie intake.
You Are Not Limited to Diets 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 an obligate 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 might cause muscle loss.
Secondly, because cats are obligate carnivores, they’re 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 their carnivorous needs first. From their claws to their metabolism, your cat’s body is optimized to hunt and eat animals. That doesn’t change if the cat is overweight, obese, or underweight.
Why Trust Cats.com
Before selecting products for testing, I spent several hours researching the subject of obesity in cats and gaining insight from members of our panel of veterinary advisors. With the understanding that diet is just one piece of the weight loss puzzle for cats, I selected an assortment of high-moisture cat foods with moderate calorie content between 20 and 35 calories per ounce.
To test these products, I purchased them at full retail price and tried them at home with my two cats, Wessie and Forest. While my cats provided their input on the products’ taste, texture, and general appeal, I made observations on the appearance, aroma, consistency, and packaging.

#3 Best for Indoor Cats: Wellness CORE Grain-Free Indoor Chicken & Chicken Liver Recipe Canned Cat Food
- Price: $5.63 per day
As an indoor cat food, this recipe is formulated to accommodate cats with lower activity levels and reduced calorie needs. It’s 29 calories per ounce and is among the lower-calorie foods you can buy.
Unlike the majority of indoor foods, this food is a meaty, protein-packed product. It emphasizes high-protein animal ingredients like chicken, chicken liver, chicken meal, and turkey.
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.
This food is around 22% carbohydrate on a dry matter basis, making it slightly more carb-heavy than the ideal feline diet.
Ingredients
Chicken, Chicken Liver, Chicken Broth, Turkey Broth, Chicken Meal, Turkey, Pea Protein, Dried Ground Peas, Natural Flavor, Cranberries, Pea Fiber, Ground Flaxseed, Guar Gum, Tricalcium Phosphate, Potassium Chloride, Choline Chloride, Taurine, Cassia Gum, Xanthan Gum, Dried Kelp, Chicory Root Extract, Yucca Schidigera Extract, Salt, Alfalfa Meal, Iron Proteinate, Zinc Proteinate, Thiamine Mononitrate, Vitamin E Supplement, Copper Proteinate, Manganese Proteinate, Sodium Selenite, Niacin, d-Calcium Pantothenate, Pyridoxine Hydrochloride, Riboflavin Supplement, Vitamin A Supplement, Biotin, Potassium Iodide, Vitamin D3 Supplement, Vitamin B12 Supplement, Folic Acid.

#4 Best Ethically Sourced: Open Farm Grass-Fed Beef Rustic Blend Wet Food
- Price: $3.10 per day
When it comes to high-quality ingredients and 100% traceability, you can trust Open Farm. What makes this Open Farm formula great for weight loss is the fact that it is packed with real animal protein and hydrating moisture but has moderate fat and calorie content (about 31 calories per ounce). This recipe also contains higher-than-average fiber, which might help your cat feel fuller for longer between meals.
With humanely raised beef as the primary ingredient, this recipe is rich in amino acids which helps support your cat’s lean muscle mass. Unfortunately, both of the added fats are plant-based and there are a significant number of plant-based ingredients on the whole. That being said, this recipe is still incredibly rich in protein and moisture and only contains about 11% carbohydrate on a dry matter basis.
Ingredients
Humanely Raised Beef, Beef Bone Broth, Pumpkin, Carrots, Spinach, Red Lentils, Agar Agar, Non-GMO Cranberries, Garbanzo Beans (Chickpeas), Chicory Root, Sunflower Oil, Coconut Oil (preserved with mixed tocopherols), Salt, Vitamin A Supplement, Vitamin D3 Supplement, Vitamin E Supplement, D-Calcium Pantothenate, Thiamine Mononitrate, Riboflavin Supplement, Biotin, Folic Acid, Vitamin B12 Supplement, Zinc Amino Acid Chelate, Iron Amino Acid Chelate, Copper Amino Acid Chelate, Manganese Amino Acid Chelate, Sodium Selenite, Dried Kelp, Potassium Chloride, Dandelion Greens, Choline Chloride, Taurine, Turmeric.

This simple recipe features shredded chicken and duck in gravy, making it a good choice for cats that prefer chunks and shreds of minimally processed meat. It includes chicken broth as the first ingredient, meaning that the low-calorie density is largely thanks to the food’s unusually high water content.
Because it emphasizes animal protein, this food will help your cat maintain lean muscle mass while gradually losing weight.

Compared to the average food, this recipe has significantly fewer synthetic additives and other supplemental ingredients.

What to Consider: Feeding Recommendations To Help Overweight Cats 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 offer weight-loss diets. These low-fat foods might be lower in calories than the average cat food, but prescription weight-loss diets make heavy use of carbohydrates and non-nutritive fillers your cat might be better off without.
Simply put, it’s possible to choose a high-quality cat food and promote weight loss by reducing your cat’s daily portion and increasing their activity level.
Your cat should lose weight at a slow, steady rate of about 1 to 2% of their current weight each week. For example, if your cat currently weighs 25 pounds, they should lose between 4 and 8 ounces during their 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, and losing weight too quickly can create its own health consequences.
The 80% Technique
Assuming your cat is currently maintaining an unhealthy body weight, determine the number of calories they eat now and gradually cut back to 60 to 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 pounds, then their maintenance intake will be roughly 220 calories per day. When your cat is eating for a slimmer body, they are living with a calorie deficit. This encourages gradual weight loss until your cat reaches their goal 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 their nutrient intake. Your cat’s weight loss should be not come at the expense of their 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.
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 is to stay disciplined and consistent.
When changing your cat’s diet make the transition slowly, feeding both their old food and the new food. Over the course of a week or two, gradually increase the amount of new food and decrease the amount of old food until there are eating only the new food.
If you’re trying to convert your cat from dry food to wet cat food, sure your cat is eating the new food. Cats can develop very strict food preferences depending on what they were exposed to early in life, and it can be difficult for some cats to switch to eating a different type of food later in life.
Give it a good try, but make sure your cat is eating the new food. Cats can become very sick if they don’t eat enough, and your cat is not going to benefit from the good nutrition of a food they won’t eat.
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?

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’re looking for best cat food for weight loss, 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 might 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, also make an effort to increase your cat’s activity level with daily play sessions.
Is wet or dry cat food better for weight loss?
You can help your cat lose weight using either dry food or wet food. However, 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. Wet food also tends to be higher in protein and lower in carbohydrates, which can also support healthy weight loss.
