Many adults use meal replacement products to help them lose weight, but a new study by researchers at the Children's Hospital of Philadelphia found that the diet method may not help obese teens keep weight off.
The study involved 113 obese adolescents, who were monitored for one year, reports the Los Angeles Times. One group of teens ate fewer calories (1,300 to 1,500 a day) of regular food, while another group consumed three SlimFast Shakes and a "pre-packaged meal" along with servings of fruits or vegetables.
In the end, the study showed that the shakes worked better than the low-calorie diet plan, but only for a while. The weight eventually came back for nearly all of the teens, and after one year, there were "no significant differences between groups in percentage change in BMI at month 12."
Are you surprised by these findings? Have you tried dieting using meal replacements? Did you lose weight, only to have it come back after a while?
