A new study has found that Weight Watchers is the most effective commercial weight loss program and added that people who participated in the program were able to stick to their regimen longer and shed more pounds compared to those who took part in behavioral weight loss programs led by health professionals.
Researchers at Baruch College at the City University of New York tested the effectiveness of Weight Watchers program by comparing it against two psychologist-led behavioral weight loss programs. Around 141 obese men and women were randomly selected to follow either a 48 week Weight Watchers program, a 48 week nonsurgical, medically supervised weight loss program led by a health professional or a 12 week medically supervised program followed by 36 weeks of Weight Watchers.
The researchers found that those who took part in the Weight Watchers program lost an average of 13 pounds compared to just 8 pounds in the combined program while those in the professional weight loss program lost 12 pounds. The study has been published in the journal Obesity.
"Weight Watchers really can produce clinically meaningful weight loss for a lot of people. It can be very convenient for people to access, and professional programs don't always have that convenience and accessibility", lead researcher Angela Marinilli Pinto said.
