The website gave me a meal plan without asking me my height or weight!
They have some info about the research:
"Healthy, overweight women between the ages of 20-45 years of age with a Body Mass Index (BMI) between 25 and 35 kg/m2 were recruited for the study.."
"Women who followed the Two Week Tune Up plan lost an average of 5.3 pounds in two weeks. "
It's interesting that they say how many pounds the women gained backed after they stopped the diet?
But at least they are not kidding themselves look at the way they answered this question:
"Isnít this just a crash diet?"
"If you are looking to lose a few pounds, the Two Week Tune Up is a reduced-calorie dietary pattern that is rich in lean protein with 30-40 minutes of daily walking." www.yoplait.com/twoweektuneup/faq
