Like Us, Pets Must Eat Right and Keep Moving
Obesity, a severe and debilitating illness, is the most common nutritional disease in both animals and people. The latest survey of 121 veterinarians in 36 states by the Association for Pet Obesity Prevention (APOP) and corroborating American Veterinarian Medical Association data reveal we have 80 million fat cats and obese dogs; that’s more than 58 percent of dogs and 52 percent of domesticated cats. “Pet obesity remains the leading health threat to our nation’s pets,” says Dr. Ernie Ward, APOP’s founder, from the organization’s headquarters in Calabash, North Carolina.
Current medical consensus states that an animal is obese if it weighs at least 15 percent more than its ideal weight. But looking at body composition is more accurate, based on measurements top-to-bottom and side-to-side and depth to the ribs and spine.
Animals aren’t born fat. Obesity results from too many calories in food, snacks and treats, paired with a lack of aerobic exercise. People may believe they are showing love by rewarding begging with treats, but they actually may be slowly killing their companions with kindness, putting them on a path toward painful and costly medical problems.
These can include cancer, cardiac problems, complications from drug therapy, difficulty breathing, heat intolerance, hypertension, intervertebral disk disease, orthopedic conditions (including arthritis), lethargy and ruptured ligaments. Also, because excess body fat first deposits in the cavities of the chest and abdomen and under the skin, hypothyroidism and diabetes mellitus can develop, so screen overweight animals for these disorders prior to treatment for obesity.
Tackling obesity involves restricting calories and increasing the metabolic rate with a controlled exercise program. Diet and exercise are the two most vital factors in fighting fat.
Simply switching to a store-bought “lite” pet food is inadequate because many are designed to maintain, not lose, weight. Also, many products contain chemicals, byproducts and unhealthy fillers that are contrary to a holistic program.
A homemade restricted-calorie diet is the best choice for obese animals. The second is a processed “obesity-management” diet available through veterinarians, although many of these also contain chemicals, byproducts and fillers. Such diets can be used to attain the target weight, and then replaced with a homemade maintenance diet.
Foods high in fiber work well for shedding pounds because they increase metabolism. Vegetable fiber decreases fat and glucose absorption. Fluctuating glucose levels cause greater insulin release that can lead to diabetes; because insulin is needed for fat storage, low, stable levels are preferred. Fiber also binds to fat in the intestinal tract and increases the movement of digested food through the intestines.
Several natural therapies may be helpful for treating animal obesity. These include herbs such as cayenne, ginger and mustard; white bean extract; chromium; carnitine; hydroxycitric acid (HCA); epigallocatechin gallate (EGCG); and coenzyme Q10. All have been widely used with variable success, although not yet thoroughly researched or clinically proven.
A supplement called Vetri-Lean appears promising. Based on a white bean extract, it has cut starch digestion by up to 75 percent in the company’s clinical tests. The formula also has EGCG from green tea extract to boost metabolism, inhibit carbohydrate-digesting enzymes and help maintain normal blood insulin levels, all to help dissolve fat and control appetite. Chromium polynicotinate, another ingredient, also helps to curb appetite, build muscles and reduce fat.
Exercise is Key
As with humans, a regular program of supervised exercise is essential to pet health. Experience shows that it must be combined with a diet and supplement plan to achieve maximum results for overweight pets. Along with burning off excess calories, even mild exercise works to reduce hunger, improve muscle strength and aerobic capacity and improve functioning of organs. Plus, as veterinarians further attest, the activity is mentally stimulating for both animals and guardians, while decreasing behavioral problems.
There is no one best exercise program for every animal; a sensible plan must be personalized to needs and abilities. Consult a veterinarian to determine the best regimen. As always, prevention is better than a cure, so staying alert to signs of additional pounds and keeping an animal from becoming obese in the first place is optimum.
