Shedding pounds often tops many people’s New Year’s resolution list and that can mean checking out popular diet plans on the market. A new study gives some perspective on four popular diet plans. Researchers from Tufts University assigned 160 overweight or obese individuals to the Atkins, Ornish, Weight Watchers or Zone diet. After one year, the results showed that people who followed their diet plan closely lost the most weight no matter which diet they were on. The study concluded that in the short-term all four diets worked equally well. However, keep in mind that many diet approaches can help you lose weight in the short term. The question still is: Are these diets effective or safe in the long term – for the rest of your life? There is still no conclusive evidence.
