How the study was done
Participants included obese adults (73 adults; 88% women; mean age 48.4 years) who were placed in an intervention group eating approximately one cup of mushrooms per day in place of meat, and a standard diet control group.
At the end of the one-year trial, researchers found that participants who substituted mushrooms for meat lost seven pounds, showed improvements in body composition compared to participants on the standard diet, and maintained the weight loss.
Specifically, those in the intervention group reported lower calorie and fat intake (123 calories, 4.25 grams respectively, per day); lost more pounds and percentage body weight (7 pounds, 3.6% of their starting weight); achieved lower body mass index (1.5kg/m2), waist circumference (2.6 inches) and percent total body fat (0.85%) compared to participants on the control diet.
The new findings build on previous research, which showed that increasing intake of low-energy-density foods, specifically mushrooms, in place of high-energy-density foods, like lean ground beef, can be an effective method for reducing daily energy and fat intake while still feeling full and satiated after the meal.
Lawrence Cheskin, M.D., F.A.C.P., Associate Professor, Department of Health, Behavior and Society at Johns Hopkins Bloomberg School of Public Health, authored the research study and can discuss the role of mushroom substitution in the area of weight management.
