CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation application of U.S. application Ser. No. 10/054,093 filed on Jan. 22, 2002, which is incorporated herein by reference in its entirety. TECHNICAL FIELD [0002] The invention generally relates to a pet food for use in a weight management system for companion animals. More particularly, the weight management system includes a high protein, low caloric daily diet that includes a functional ingredient that further modulates metabolism and build lean muscle mass in companion animals. BACKGROUND OF THE INVENTION [0003] In westernized societies the most prevalent form of malnutrition in humans is over-consumption of calories resulting in excess body fat. Studies have shown that approximately 20-30% of dog and cat populations are overweight and obese (over-fat). Obesity in domesticated dogs and cats has been linked to the development of numerous diseases including renal failure, diabetes, arthritis and thyroid dysfunction. Overweight dogs have an increased risk of developing transitional cell carcinoma of the bladder. Further, it is well established that obesity is a predisposing factor to idiopathic hepatic lipidosis in cats, however, their inability to convert dietary C18 essential fatty acids into long chain fatty acids creates a need for dietary consumption of 20 carbon long chain fatty acids. Such a dietary requirement leaves cats extremely vulnerable to weight disorders and weight-associated diseases such as diabetes (Appleton et al., 2000). [0004] Obesity generally is considered present when body weight of the companion pet is 15% or more greater than optimum, which is the point at which health problems begin increasing with increasing weight. Generally speaking, the incidence of obesity in domestic animals increases with age. Similar to humans, as a dog ages, body fat increases, and lean body mass decreases. However, obesity commonly goes unnoticed by the animal's owner and, thus, poses a life-threatening problem to domesticated animals. [0005] Some pet food compositions formulated to prevent or treat obesity in animals have been described. U.S. Pat. No. 6,071,544 teaches that a specific combination of long chain conjugated fatty acids (0.2 to 1.5 weight % of dry matter) together with up to 50% protein promotes weight loss in cats. A diet greater than about 16% by weight of animal-based protein is taught to reduce body fat in geriatric dogs (WO 00/51443). However, U.S. Pat. No. 5,141,755 teaches that non-meat based animal fats in a high protein, high farinaceous diet provides an ovo or lacto-ovo nutritionally balanced pet food product. U.S. Pat. No. 4,892,748 describes a low calorie dog treat that is comprised primarily of cellulose, a .beta.-1,4-glucan that affords no nutritional value to the animal. [0006] Similarly, diets disclosed for the treatment of human obesity have included compositions such as a concentrate that consists entirely of non-animal natural components, a lack of simple sugars and a flour comprising at least 50% protein, less than 15% carbohydrates and 35 to 50% plant fiber for use in the preparation of foods such as bakery products (U.S. Pat. No. 4,737,364; EP 965278 A1). Such diets are not completely without credence because hypertension, and thus risk of developing cardiovascular disease, in obese patients have been linked to disturbances in carbohydrate metabolism (Nobels et al., 1989). [0007] However, low caloric diets comprising increased ratios of amino acids to carbohydrates, such as the diet taught in U.S. Pat. No. 4,009,265, cause increased blood urea concentrations. Urea is a by-product of protein or amino acid catabolism and thus is directly related to the amount of protein in a diet. The kidneys function to remove urea from the plasma, and in this regard high protein diets place an unusual burden on the kidneys which can lead to severe consequences over time including developing azotemia or uremia. [0008] Also symptomatic of high protein diets is the potential to induce ketosis, a condition that is shared in humans and dogs. Ketosis is a pathological condition in which the brain consumes ketone bodies as its major fuel source and is a diagnostic for diabetes mellitus. For example, urine abnormally high in ketone bodies is expected after a prolonged fast. However, this metabolic shift is undesirable and also leads to severe renal damage if experienced over long periods of time. [0009] Natural products derived from plants and food have frequently been the source of effective drugs, and in recent years there has been an increased interest in the analysis of these natural products, especially where a clinical benefit is claimed. For this reason, functional ingredients are often added to pet foods in order to effect a particular metabolic response. For example, EP 646325A1 describes a pet food comprised of at least 30% by weight of indigestible dextrin that demonstrates obese-improving effects by controlling blood-sugar levels and insulin secretion in dogs and cats. [0010] U.S. Pat. No. 5,962,043 teaches jojoba seed meal as a nutritional supplement in animal feed, especially companion dogs, to promote weight loss. Simmondsin is described as the active or functional ingredient, that based on previous research, results in an associated reduction in food intake and retardation of growth. These formulations include high fat and high caloric density to ensure palatability. [0011] U.S. Pat. No. 6,204,291 teaches dietary supplementation with L-carnitine, a naturally occurring acid also known as .beta.-Hydroxy-.gamma.-trimethylaminobutyrate, to dog food to promote weight loss. Carnitine is found in the body and is enzymatically combined with fatty acids to facilitate their transportation through mitochondrial membranes, thus aiding in fatty acid metabolism (Yalkowsky, S. H., 1970). Oral administration of L-carnitine for obesity in mammals has been described in U.S. Pat. No. 3,810,994. It also has been implicated in improvements in myocardial contractility and systolic rhythm in congestive heart failure, it has been administered in cases of cardiac arrythmia (U.S. Pat. No. 3,830,931; U.S. Pat. No. 3,968,241), and it has been used for increasing the level of high density lipoproteins U.S. Pat. No. 4,255,449). [0012] Prior to the present invention, current solutions have not provided a comprehensive approach in addressing the issues of weight management. Most diets simply lower caloric density, increase total carbohydrates by increasing fiber which leads to reduced palatability, thereby creating a diet that leaves the animal hungry and, sometimes, induces lean muscle loss. [0013] The present invention provides a long-sought after weight management system for companion animals, and in particular obese animals, for treating and preventing obesity through dietary intervention in companion animals such as dogs and cats. The present invention also increases the lean body mass of companion animals as well as enhancing the satiety and decreasing voluntary food intake of an animal. BRIEF SUMMARY OF THE INVENTION [0014] The present invention provides a comprehensive weight management system to help optimize the body composition of a domestic animal through dietary intervention by providing a pet food product comprising about 35 to about 70% by weight of a protein, about 4 to about 10% by weight of a fat, about 5 to about 25% by weight of a fiber, about 10 to about 35% by weight of a digestible carbohydrate, and about 0.1 to about 1% by weight of a functional ingredient. [0015] An additional object of the invention is a process for producing a pet food product that provides comprehensive weight management in companion animals by adding about 35 to about 70% by weight of a protein, about 4 to about 10% by weight of a fat, about 5 to about 25% by weight of a fiber, about 10 to about 35% by weight of a digestible carbohydrate, and about 0.1 to about 1% by weight of a functional ingredient. [0016] A further object of the present invention is a process of feeding companion animals a pet food product that provides comprehensive weight management by comprising about 35 to about 70% by weight of a protein, about 4 to about 10% by weight of a fat, about 5 to about 25% by weight of a fiber, about 10 to about 35% by weight of a digestible carbohydrate, and about 0.1 to about 1% by weight of a functional ingredient. The present invention also increases the lean body mass of companion animals, enhances satiety, decreases voluntary food intake and mitigates potential adverse medical risks associated with high protein diets.
