Well, how on earth can you have a low carb diet where you recommend that people eat 'Carbohydrate-rich' foods?
Washington, DC (PRWEB) February 28, 2009
Authors of a new study in the New England Journal of Medicine (NEJM) claim their study is proof that the only thing that matters is calories in vs. calories out when it comes to weight loss. "This is not actually true," says Josef Brandenburg, a Washington, DC personal trainer and fat-loss expert. Brandenburg says that there are two fundamental flaws in the study:
#1. Brandenburg points out that in the "Methods" section it states: "Carbohydrate-rich foods with a low glycemic index were recommended in each diet." "Well, how on earth can you have a low carb diet where you recommend that people eat 'Carbohydrate-rich' foods?" asks Brandenburg.
"The authors of this study claim that their study debunks the Atkins' diet, but you cannot actually eat carb-rich foods on Atkins' diet, no matter what their glycemic index. So nothing resembling the Atkins' diet (or the first phase of the South Beach diet for that matter) was actually tested. This is very bad science, and it is just irresponsible that the media is running this 'study' with headlines that make it sound conclusive," says Brandenburg.
#2. He also points out that all of the participants in the study were encouraged to slash 750 calories per day from their diet. "The underlying premise of low-carb diets is that calories don't count, only the carbohydrate content does. If you actually wanted to test 'low-carb vs. low-fat' then one group would have to go on an actual low-carb diet in the spirit of Dr. Atkins, and one group would have to go on a low-fat diet. This is 4th grade science," says Brandenburg.
Brandenburg asserts that what this weight loss study actually tested slightly different low-calorie diets, and that none of the groups actually went on a true low-carb diet. "It is misleading at best for the authors to go around saying things like, 'They just need to focus on how much they're eating,' as Dr. Frank Sacks has been claiming," says Brandenburg.
"If anything, the only thing this study 'proves' is that academics don't know the first thing about how to get people to lose fat. If you look at their results, they are absolutely abysmal across the board. If your best advice can only get people down 9 pounds in two years, then you probably need to go back to the drawing board and check your underlying assumptions," says Brandenburg.
