Diet plays a central role in your dog’s overall health and well-being, and it stands to reason that you want to provide your dog the best possible source of nutrition in the dog food you choose. But some nutrients, like L-Carnitine, may be unfamiliar or completely foreign. Learn more about this vitamin-like compound and how it can help your dog maintain a healthy weight.
Carnitine, or L-carnitine, is a vitamin-like compound made in the body from amino acids. It's found naturally only in animal-based protein sources. It has been used to help with fat metabolism in other species, and recent scientific studies show that it can help reduce weight in overweight dogs.
This water-soluble substance attaches to fatty acids, transporting them into cellular mitochondria, the part of the cell that converts fat into a usable form of energy. There, they are broken down through oxidation and converted to energy for all tissues, including the heart, liver, and skeletal muscles. Through this process, carnitine helps reduce the storage of body fat and the amount of fat in the bloodstream.
In a study conducted by The IAMS™ Company, overweight dogs were fed similar diets. One group was given a diet supplemented with L-carnitine while another group received a diet without supplemental L-carnitine.
After seven weeks, the group that received the diet without supplemental L-carnitine lost 1.8% body weight compared to 6.4% body weight loss from the group that was fed the L-carnitine supplemented diet. Likewise, body fat was reduced in each group by 2.4% and 4.6%, respectively.1 The study found that L-carnitine promotes loss of body weight and body fat in overweight dogs.
IAMS™ ProActive Health™ Adult Healthy Weight is formulated with L-carnitine that helps turn fat into energy, providing a path to help keep him fit for life.

Switching your dog to a new food takes some planning. Because dogs are creatures of habit, they tend to prefer their current food to a new food. Like us, they become accustomed to a food and might not be thrilled about a new routine. These useful dog-feeding tips will help you keep your dog satisfied.
When easing your dog into a change in diet, think “slow and steady.” Start by mixing 25% new food with 75% current food. Slowly change the proportions over the next three days or so by gradually increasing the new food and lessening the amount of the current food. Here’s a sample feeding schedule:
At the end of this weaning process, you should be feeding 100% of the new food. Your dog may want to eat only the old food, or not eat at all. Don’t worry — a healthy dog can miss meals for a day or two with no ill effects.
Bringing a new food into your home, pouring it into your dog’s bowl and declaring that he should eat it might cause your dog to go on a hunger strike. This is not the time to show who’s boss. It’s better to introduce the new food by using a pleasant tone of voice and gently encouraging him to try the new food.
Persistence is key! For the first two days of the food transition, don’t give your dog treats or table scraps. Dogs train us as much as we train them. Giving in to their demands only reinforces refusal behavior and makes it more difficult to make a nutritious dietary change.
Switching diets may be more challenging when changing from a moist food to a dry food. If your dog continues to resist eating dry food, mix in a little warm water. You might even want to put the moistened food in the microwave for a few seconds. If you mix the food with water, be sure to throw away the uneaten portion after 20 minutes to prevent spoilage. The same rule applies for canned and pouch food. After the dog has become accustomed to the moistened food, you can wean him onto completely dry food. To do this, follow the same mixing instructions outlined above.
