Atkins, Dukan, South Beach or whether it is the Graham Diet, we all want to try it to lose weight and celebrities like Jennifer Aniston swear by it. But the following study claims that despite the claims, branded diets don’t vary much in their results.
Weight Loss Diets: The Truth About Low-Carb and Low-Fat Diets
Low-carbohydrate or low-fat diets resulted in the most weight loss, but despite a difference of a few pounds between groups, all the programs in the study were about equally effective, said lead author Bradley C. Johnston, of the Hospital for Sick Children Research Institute in Toronto and McMaster University in Hamilton, Ontario.
The analysis included 49 randomized controlled trials that tested 11 popular branded diets for at least three months. All of the participants were overweight or obese, and they all had daily nutrient or calorie targets. Some had exercise goals as well.
The low-carbohydrate diets, like Atkins, South Beach, and Zone, require that no more than 40 percent of daily calories come from carbohydrates and another 30 percent come from protein.
The low-fat diets, including the Ornish and Rosemary Conley diets, specify that less than 20 percent of calories come from fat, and 60 percent come from carbohydrates.
Johnston and his team also included trials of moderate macronutrient diets, like Biggest Loser, Jenny Craig, Volumetrics, Nutrisystem and Weight Watchers, which also require around 60 percent of calories from carbohydrates but allow more from fat and less from protein than the low-fat diets studied.
Compared to no diet at all, each of the diets produced more weight loss, but low-fat and low-carb were most successful, according to results in JAMA.
Bottomline About Weight-loss diets
Johnston said it best, any diet program should include exercise and behavioral support. Eating a low-carb or low-fat based diet every day isn’t going to be very beneficial unless you’re maintaining a healthy workout regimen. Although it can be extremely hard to lose weight, it’s extremely easy to gain the weight you previously lost right back. So if you want to lose weight and keep it off, start implementing more physical activity into your lifestyle. Because let’s face it, your low-carb or low-fat diet can’t do all the heavy lifting for you; pun intended.
