Isoflavone compositions for reducing accumulation of body fat in male mammals, and methods for their use
View Patent ↗Edible compositions useful for weight management in male animals are disclosed. The compositions comprise one or more isoflavones or isoflavone metabolites and are particularly useful for reducing or preventing the accumulation of body fat. Also disclosed are methods useful for weight management in an animal utilizing compositions comprising one or more isoflavones. The compositions and methods are particularly useful for the reduction or prevention of body fat accumulation during periods of excess caloric intake, and preferably have a sparing effect on lean body mass.
1. A method for reducing fat accumulation in a male mammal consuming calories in excess of its minimum daily requirement, the method comprising identifying a male mammal, determining that the male mammal is consuming calories in excess of its minimum daily requirement, and providing to the male mammal on a regular basis a comestible composition comprising one or more isoflavones or metabolites thereof in an amount effective for reducing deposition of subcutaneous or intramuscular fat in the body of the male mammal.
2. The method of claim 1 wherein the comestible composition is a pet food, a human food, or a food supplement to be taken directly or added to a human food, pet food, or to animal feed.
3. The method of claim 1 wherein the mammal is a human or a companion animal.
4. The method of claim 3 wherein the companion animal is a dog or a cat.
5. The method of claim 1 , further comprising determining that the male mammal is a companion animal that has been neutered; is post-andropausal; has reduced circulating estradiol concentrations relative to a healthy, nonobese male animal of the same species or breed; has reduced ability to convert testosterone into estradiol relative to a healthy, nonobese male animal of the same species or breed; or has reduced aromatase activity relative to a healthy, nonobese male animal of the same species or breed.
6. The method of claim 1 , wherein the composition has a sparing effect on lean body mass.
7. The method of claim 5 , further comprising the step of determining that the companion animal has been neutered after weaning but before reaching sexual maturity, and wherein the comestible composition is provided to the companion animal before the animal reaches a normal adult body weight.
8. The method of claim 1 , wherein the composition is provided by administering to the male mammal on a daily basis.
9. The method of claim 1 , further comprising determining that the male mammal is a companion animal that has not been neutered and is not post-andropausal.
10. The method of claim 1 , further comprising the step of determining that the male mammal is beyond the mid-point of the life expectancy for its species or breed.
11. The method of claim 7 , wherein the companion animal is a neutered puppy or kitten.
12. The method of claim 5 , further comprising the step of determining that the circulating estradiol of the animal is less than about 80% of a healthy, nonobese male animal of the same species or breed.
13. The method of claim 5 , further comprising the step of determining that the circulating estradiol of the animal is less than about 50% of a healthy, nonobese male animal of the same species or breed.
14. The method of claim 5 , further comprising the step of determining that the circulating estradiol of the animal is less than about 20% of a healthy, nonobese male animal of the same species or breed.
15. The method of claim 5 , further comprising the step of determining that the circulating estradiol of the animal is less than about 10% of a healthy, nonobese animal of the same species or breed.
