The consensus among vets is to implement a new diet slowly. Cats may stop
eating if you suddenly confront them with different food.
“The bottom line is, you have to cut calories in proportion to the amount of
work the cat is doing,” says Johnny Hoskins, DVM, PhD, DACVIM, of Branson, Mo.
“We try to do it over a several-month time period.” The Association for
Pet Obesity Prevention says a loss of about 1 pound per month is healthy.
The Best Cat Diet
Research has shown that there are several ways of approaching a cat diet.
Fortunately, there are many commercial varieties of therapeutic canned and dry
foods that are palatable and nutritionally sound. Hoskins tells WebMD
that it’s fine to combine canned and dry foods for your cat’s diet.
Joe Wakshlag, DVM, PhD, DACVN, is a clinical nutritionist with Cornell
University’s College of Veterinary Medicine. He recommends a diet of
low-calorie canned food because it has more fillers than dry food. The
recommendation is not aimed at your cat, but at you. The canned food tends to
make you, the caretaker, feel you are giving your cat enough to eat. Wakshlag
also says to make sure you don’t forget to look at the calorie count on the
label. “I think the bottom line is you have to replace fat with protein and
carbohydrates,” he tells WebMD. “The key is to remove fat, which is
contributing the most calories.”
The latest trend in feline weight loss management is a high-protein/low-carb
diet, the so-called “Catkins” diet. Hoskins says he prefers low-carb cat
diets because he believes carbohydrates raise the risk of diabetes. Diets that
contain L-carnitine help maintain lean body mass, he says.
Other research has shown that obese cats lose weight without losing lean
body mass following low fat/high fiber diets and high fat/low carb diets. Both
kinds of diets have been shown to improve glucose tolerance.
Look at the label on the cat food to make sure your cat is going to get the
right nutrients for his stage in life and that the top ingredients are meat,
meat byproducts, or seafood. Nutrients like taurine and B vitamins are also
Keep in mind: cats are natural carnivores, so vegetarian diets won’t do.
