Obese and overweight animals have an increased risk of many chronic diseases including heart disease, diabetes, hypertension, stroke, dyslipidemia, certain types of cancer, apnea and osteoarthritis. Therefore, it is essential for overweight and obese animals, including humans and pets, to lose excessive body fat to maintain health and quality of life. Unfortunately, losing excessive body fat or maintaining healthy weight after weight loss is difficult to achieve and various solutions can have adverse consequences, e.g., loss of lean body mass during weight loss or weight rebound after weight loss.
Obesity is among the most serious health problems in humans and pets and considered to be the leading preventable cause of death. Maintaining a healthy weight is critical for optimal metabolism, normal physical activity and good health. There is, therefore, a need for methods and compositions to increase satiety, promote body fat loss, and maintain lean body mass and healthy weight, for better the health and wellness of animals and methods to determine the efficacy of weight loss diets.
In one embodiment, a method of determining the efficacy of a weight loss diet for a canine can comprise analyzing a first serum or plasma sample from the canine for a biomarker selected from the group consisting of 3-methylhistidine, 1-methylhistidine, and a combination thereof; determining the amount of the biomarker in the first serum or plasma sample; analyzing a second serum or plasma sample for the biomarker after the canine has been administered the weight loss diet; determining the amount of the biomarker in the second serum or plasma sample; and determining the weight loss diet is efficacious if the amount of the biomarker in the second serum or plasma sample has decreased from the amount of the biomarker in the first serum or plasma sample or determining the weight loss diet is inefficacious if the amount of the biomarker in the second serum or plasma sample has not changed or increased from the amount of the biomarker in the first serum or plasma sample.
In another embodiment, a method of providing an efficacious weight loss diet for a canine can comprise analyzing a first serum or plasma sample from the canine for a biomarker selected from the group consisting of 3-methylhistidine, 1-methylhistidine, and a combination thereof; determining the amount of the biomarker in the first serum or plasma sample; analyzing a second serum or plasma sample for the biomarker after the canine has been administered the weight loss diet; determining the amount of the biomarker in the second serum or plasma sample; determining the weight loss diet is efficacious if the amount of the biomarker in the second serum or plasma sample has decreased from the amount of the biomarker in the first serum or plasma sample or determining the weight loss diet is inefficacious if the amount of the biomarker in the second serum or plasma sample has not changed or increased from the amount of the biomarker in the first serum or plasma sample; and wherein, when the weight loss diet is inefficacious, providing an efficacious weight loss diet to the canine that comprises protein, fat, carbohydrates, omega-3 fatty acids, and isoflavones; wherein the protein to carbohydrate is in a ratio ranging from 4.5:1 to 2.5:1 by weight as fed.
Other and further objects, features, and advantages of the invention will be readily apparent to those skilled in the art.
The terms “treating”, “treat”, and “treatment” embrace both preventative, i.e., prophylactic, and palliative treatment.
The term “efficacious”, when referring to a weight loss diet, refers to a weight loss diet that maximizes loss of body fat and/or minimizes or prevents loss of lean body mass during administration of the weight loss diet to a canine.
The term “food” or “food product” or “food composition” means a product or composition that is intended for ingestion by a canine and provides nutrition to the canine.
The term “carbohydrate” refers to carbohydrates that are digestible, e.g., sugars and starches, and does not include fiber, e.g., cellulose or fermentable fibers.
The term “crude fiber” refers to part of insoluble fiber found in the edible portion of the plant cell wall, and crude fiber is a measure of the quantity of indigestible cellulose, lignin, and other components of this type in foods.
The term “total dietary fiber” refers to the portion of plant-derived food that cannot be completely broken down by canine digestive enzymes and includes both soluble and insoluble fibers. Soluble fiber dissolves in water and is fermented in the colon by gut microbiota. Examples of soluble fibers are beta-glucans, guar gum, Psyllium, inulin, wheat dextrin, resistant starches. Insoluble fiber does not dissolve in water. Examples of insoluble fibers are cellulose and lignin.
The term “regular basis” means at least monthly administration and, in one aspect, at least weekly administration. More frequent administration or consumption, such as twice or three times weekly, can be performed in certain embodiments. In one aspect, an administration regimen can comprise at least once daily consumption.
The term “single package” means that the components of a kit are physically associated in or with one or more containers and considered a unit for manufacture, distribution, sale, or use.

More frequent administration or consumption, such as twice or three times weekly, can be performed in certain embodiments. In one aspect, an administration regimen can comprise at least once daily consumption.
According to the presently described methods, administration, including administration as part of a dietary regimen, can span a period ranging from parturition through the adult life of the canine. In certain embodiments, the canine can be a young or growing canine. In other embodiments, administration can begin, for example, on a regular or extended regular basis, when the canine has reached more than about 10%, 20%, 30%, 40%, or 50% of its projected or anticipated lifespan. In some embodiments, the canine can have attained 40, 45, or 50% of its anticipated lifespan. In yet other embodiments, the canine can be older having reached 60, 66, 70, 75, or 80% of its likely lifespan. A determination of lifespan may be based on species, gender, size, genetic factors, environmental factors and stressors, present and past health status, past and present nutritional status, stressors, and the like.
Such administration can be performed for a time required to accomplish one or more objectives described herein, e.g., preserving lean body mass in a canine during weight loss. Other administration amounts may be appropriate and can be determined based on the canine's initial weight as well as other variables such as species, gender, breed, age, desired health benefit, etc.
The moisture content for such efficacious food compositions varies depending on the nature of the food composition. The efficacious food compositions may Ref No. 18931 be dry compositions (e.g., kibble), semi-moist compositions, wet compositions, or any mixture thereof. In one embodiment, the pet food composition can be a complete and nutritionally balanced pet food. In this embodiment, the pet food may be a “wet food”, “dry food”, or food of “intermediate moisture” content. “Wet food” describes pet food that is typically sold in cans or foil bags and has a moisture content typically in the range of about 70% to about 90%. “Dry food” describes pet food that is of a similar composition to wet food but contains a limited moisture content typically in the range of about 5% to about 15% or 20% (typically in the form or small biscuit-like kibbles). In one embodiment, the compositions can have moisture content from about 5% to about 20%. Dry food products include a variety of foods of various moisture contents, such that they are relatively shelf-stable and resistant to microbial or fungal deterioration or contamination.

In one embodiment, the prebiotic can be chicory root, chicory root extract, inulin, or combinations thereof. Generally, prebiotics can be administered in amounts sufficient to positively stimulate the healthy microflora in the gut and cause these “good” bacteria to reproduce. Typical amounts range from about one to about 10 grams per serving or from about 5% to about 40% of the recommended daily dietary fiber for a canine. The probiotics and prebiotics can be made part of the composition by any suitable means. Generally, the agents can be mixed with the composition or applied to the surface of the composition, e.g., by sprinkling or spraying. When the agents are part of a kit, the agents can be admixed with other materials or in their own package. Typically, the food composition contains from about 0.1 to about 10% prebiotic, in one aspect, from about 0.3 to about 7%, and in one specific aspect, from about 0.5 to 5%, on a dry matter basis. The prebiotics can be integrated into the compositions using methods known to skilled artisans, e.g., U.S. Pat. No. 5,952,033.
A skilled artisan can determine the appropriate amount of food ingredients, vitamins, minerals, probiotics, prebiotics, antioxidants, or other ingredients to be used to make a particular composition to be administered to a particular canine. Such artisan can consider the canine's species, age, size, weight, health, and the like in determining how best to formulate a particular composition comprising such ingredients. Other factors that may be considered include the desired dosage of each component, the average consumption of specific types of compositions by different canine (e.g., based on species, body weight, activity/energy demands, and the like), and the manufacturing requirements for the composition.

The invention can be further illustrated by the following example, although it will be understood that this example is included merely for purposes of illustration and is not intended to limit the scope of the invention unless otherwise specifically indicated.
In this study, 30 overweight dogs were randomized into two groups with 15 dogs per group based on their baseline maintenance energy requirement (MER), body weight, % body fat, and genders. The dogs in both the control and test groups were fed 75% if their baseline MERs during the first 4 months of the weight loss study and then 60% of their baseline MERs during the last 2 months of the weight loss study. The body composition was determined with a DEXA machine. The diets are shown in Table 1.
There was no significant difference in lean body mass between baseline and any of the three time points (2 months, 4 months, and 6 months) in dogs fed the test diet. On the contrary, dogs fed the control diet lost significant amount of lean body mass at all three time points compared with baseline as shown in Table 2.
Dogs in both groups lost significant amount of body fat compared with baseline. However, dogs fed the test diet lost more body fat than the control dogs (5.93 kg vs 4.98 kg) at the end of the 6-month weight loss study as shown in Table 3.
Several markers associated with muscle growth/breakdown were analyzed. Surprisingly, 2 markers were found that distinguished the present test diet from traditional diets such as the control diet. The results are shown in Table 4.
As shown in Table 4, 3-methylhistidine and 1-methylhistidine were shown to significantly differentiate the test diet from the control diet. As such, 3-methylhistidine and 1-methylhistidine can be used as diagnostic markers for determining the efficacy of weight loss diets. The use of these markers can aid a veterinarian in determining whether a weight loss diet is a healthy weight loss diet, e.g., preserves lean body mass, or an unhealthy weight loss diet, e.g., loss of significant lean body mass without the need of expensive or unavailable DEXA (dual-energy X-ray absorptiometry) or QMR (quantitative magnetic resonance) scanners.
