According to a systematic review published in Cardiovascular Quality and Outcomes, the Atkins, South Beach, Weight Watchers or Zone diets are not all they’re believed to be by desperate dieters. A team of researchers reviewed randomized controlled trials in order to examine these popular diets to establish which of them offers the best benefits.
Researcher Renee Atallah of the Center for Clinical Epidemiology and Lady Davis Institute at Jewish General Hospital of McGill University, Montreal, Canada believes that there is not enough data on these diets and definitely not enough tests to compare their strengths and weaknesses. She states: “These trials need to assess both long-term weight loss and changes in other heart disease risk factors so that we better understand the potential benefits with their use.”
The investigative team closely analyzed the specifics of each fad diet. Their results proved to be very much like that of other previous studies. All diets are effective when followed properly.
They also discovered that the “weight loss benefits” were consistent as were other “health factors.” Specifically, the four fad diets have similar effects on blood pressure, blood sugar levels, cholesterol and other cardiovascular risk factors.
Senior author Dr. Mark Eisenberg, Professor of Medicine at Jewish General Hospital/McGill University in Canada, reported: “With such a small number of trials looking at each diet and their somewhat conflicting results, there is only modest evidence that using these diets is beneficial in the long-term.”
He concluded: “What is incredible to me is that dieting is a multibillion-dollar industry, and if we look at the amount of data out there, it’s minuscule in comparison to the market. There are very few well-done studies, and most of them look at the short term. And weight loss is obviously a long term issue.”
