Soy-Related Diet may not be as Accurate

   
BusinessOn a Research conducted recently, Overweight women who ate 500 fewer calories a day than normal while consuming an extra 18 grams of soy-rich food daily for 12 weeks didn't lose any more weight than their peers who didn't add the extra soy, Dr. Marie-Pierre St. Onge of St. Luke's/Roosevelt Hospital in New York City and colleagues found. Adding soy-protein-rich foods while cutting calories doesn't accelerate weight loss, a new study shows.

St. Onge and her team conclude in the March issue of the Journal of the American Dietetic Association in which she said "Our results do not lend support to the emerging notion those soy-protein-rich foods could be considered potential functional foods for weight management, in the quantities consumed in this study."

The researchers note that some studies have suggested adding soy to the diet could promote weight loss, and the Food and Drug Administration has approved health claims stating that eating 25 grams of soy protein daily in conjunction with a diet low in saturated fat and cholesterol can cut heart disease risk. To investigate whether adding soy to the diet could enhance weight loss while promoting heart health, they randomized 75 women to the low-calorie diet plus 15 grams of soy per 1,000 calories consumed daily, or a low-calorie diet only.

It may be necessary to eat more soy to achieve significant weight loss benefits, while consuming soy in a protein shake might also be more effective than eating soy-rich foods, the researcherís state.

Just 49 women completed the study, in which those women in the soy group were provided with the foods to eat, but toward the end of the study, many did not consume the prescribed 18 grams daily. It may be necessary to eat more soy to achieve significant weight loss benefits, while consuming soy in a protein shake might also be more effective than eating soy-rich foods, the researcherís state.
