Buyer’s Guide

While it may not seem like a big deal, a gain of a pound or two could also be significant for your cat. Being overweight is very dangerous for your cat. It can lead to many health issues such as Type 2 Diabetes, heart disease and osteoarthritis. A significant weight gain can also reduce your cat’s lifespan, which is something no cat parent wants. The best way to help your cat lose weight is increasing daily exercise and switching them to a low-calorie cat food.

However, it is important to remember that switching your cat to a low-calorie isn’t enough. Your cat, regardless of weight, still needs a good balance of nutrients to ensure their health. Calorie content is just one aspect you should consider. Your feline will still need a good balance of protein, fats, carbohydrates and fiber. In general, wet foods are better for losing weight as compared to dry food.

Keep in mind that drastically reducing your cat’s daily caloric intake will be just as unhealthy as being overweight. Reducing your pet’s portions gradually is the best way to encourage weight loss.

The Risks of Obesity in Cats

While obesity is a fairly common in cats, it affects their overall health in many ways. The risks of obesity in cats include:

  • Obesity puts a great deal of stress on your cat’s bone structure. With time, this can cause many issues with bones and joints. Obese cats are at a higher risk for developing osteoarthritis, a disease where the joints progressively degenerate and become weaker.
  • Being overweight has also been linked to Type 2 Diabetes in cats. In fact, it is one of the biggest risk factors for the disease in felines.

  • Cats that are overweight are also at risk for developing cardiovascular diseases. Obesity can cause your cat’s blood pressure to fluctuate, which eventually leads to heart disease.
  • Even being moderately overweight can reduce your cat’s lifespan. A striking 2.8 fold increase in mortality has been shown in obese cats between the ages of 8 and 12.
  • An excess of fat in the chest cavity and abdomen can affect your cat’s respiration and reduce his heat tolerance.
  • Cats that are overweight are at a higher risk for developing urinary infections and bladder stones.
  • Overweight cats have troubled heart and lung function which can lead to anesthetic complications during surgery.

Dietary Changes to Help Your Cat Lose Weight

Once you have determined your cat is overweight, you should help them lose weight with the following tips

  • Instead of cutting down portions, switch to a low-calorie cat food. You can reduce the amount of calories you feed your cat while feeding the same amount. Based on your cat’s weight, your veterinarian can guide you about the best options for your cat.
  • A cat food with moderate to low fat content (10-12%) is also preferable. Fat is the most concentrated form of calories for your cat. It is also important that the fats included are healthy fats that can easily be broken down. Fats from animal sources are the best for your feline, such as fish oil.
  • Switch to a wet food since it is generally low in carbohydrates compared to most dry foods. The moisture is also a plus for overweight cats struggling with urinary infections.

  • A cat food high in fiber is much more fulfilling. Switch to a food that is high in fiber to prevent your feline from feeling hungry soon after mealtime.
  • Break down your cat’s daily caloric intake into multiple smaller meals. This way, even though your cat is eating less calories, he won’t feel hungry as often since he’s eating more often.
  • It is important you reduce your cat’s weight slowly. Rapid weight gain and cutting off your cat’s daily portions can lead to malnourishment and fatty liver disease (hepatic lipidosis) in the long-run.
  • Encourage exercise and frequent playtime. Not only is this a great tool to get your cat to be more active, but it is also an effective way to bond with your cat.

Supplements That Could Help Your Cat Lose Weight

L-Carnitine Supplements

If your cat is severely overweight, you can consider giving him L-carnitine supplements after consulting your vet. One study followed 14 overweight cats that were given 250 mg of L-carnitine daily and also restricted in the number of calories they ate each day. A second placebo group was not given carnitine, but was still calorie-restricted.

After 18 weeks, the group fed L-carnitine supplements lost significantly more weight than the placebo group.

How to Find The Best Cat Foods for Weight Loss

If your cat is overweight, it could be due to eating the wrong food all along. When looking for cat food that will help your cat lose weight, look for the following features:

1. High in Lean Meat Proteins

More often than not, simply switching to a species-specific diet can make a big difference for overweight cats. Chicken and fish are the best proteins for an overweight cat since they provide lean proteins.

Many commercial brands use a large number of plant-based carbohydrates as fillers to bulk up food. This means less protein in your cat’s diet and high amount of carbohydrates which leads to weight gain.

2. Low to Moderate Fat Content

You cannot cut fats out from your cat’s diet entirely. Depending on how overweight your cat is, opt for a formula with low to moderate fat content (8-12%). The source of fats is just as important as the content. Animal-derived fats are healthier and easier to metabolize. This includes fat from meat and meat organs.

One of the best sources of fat in cat food is fish oil, which is also rich in essential omega fatty acids. Omega fatty acids have also been shown to play a role in weight loss among dogs.

3. Less Carbohydrates

An excess of carbohydrates is never a good idea for your pet. Carbohydrates are broken down into glucose, which can be difficult for a cat with Diabetes to digest. They are one of the main culprits in weight gain among cats. When looking for a food that promotes weight loss, make sure it does not contain an excess of potatoes and peas. Healthy and highly digestible carbohydrates for your pet include sweet potatoes and brown rice.

4. High Fiber Content

Indoor cats are generally less active than outdoor cats, but still eat a high amount of calories. Increasing the amount of fiber in your cat’s diet is not only good for their digestive system, but it can also promote weight loss. Since fiber helps your pet feel full for longer, they don’t feel the need to eat as much as they would otherwise.

5. Beneficial Supplements

Supplements such as vitamins and minerals make your cat’s food a complete and balanced meal. They also serve many vital roles such as boosting your pet’s immunity, improving digestion, and increasing fat metabolism. When buying food for weight loss, look for the following supplements:

  • L-carnitine
  • Probiotics
  • Prebiotic fiber
  • Fish oil

Frequently Asked Questions

What is the best cat food for weight loss?

There is no cookie-cutter weight loss formula that will make your cat lose weight. In fact, you can get your cat to lose weight with any nutrient-dense and well-balanced formula while controlling portions. Your best options are cat foods that are protein-rich, low-carbohydrate, and fiber-rich with moderate fat content.

How do I put my cat on a diet?

Putting your cat on a diet is not simple since drastically reducing your cat’s portions can lead to health conditions such as hepatic lipidosis. The best way to watch your cat’s calories is to switch them to a low-calorie formula or a wet food since they are lower in calories.

How much should I feed my cat for weight loss?

You can switch to a low-calorie formula and keep feeding your cat the same amount as before. This way your cat gets less calories with the same amount. Or you could consult your vet about how to gradually cut down portions to help your cat lose weight.

How many meals should you feed an overweight cat daily?

Adult cats generally do well with their daily caloric intake broken down into two meals. However, if your cat is overweight, a better approach is to break down their daily caloric intake into multiple smaller meals. This way, you can also reduce the total number of calories since your cat eats more meals and feels full for longer.

Is a grain-free cat food better for weight loss?

There is no reason to believe that grain-free cat food could lead to weight loss. However, if you feed your cat a grain-free diet, it is likely that could be the cause of their weight gain. Grain-free cat foods contain more carbohydrates which can lead to weight gain in cats.

Is wet food better for weight loss in cats?

Generally speaking, wet food contains less calories and more substantial nutrition. The ingredients are closer to their natural state, with the textures and flavors mostly intact. As a result, they are easier to digest and will help your pet feel full with less as compared to dry food.
