With the turn of the new year, millions of Americans will be eager to try to shed those excess pounds. Within a few months, we’ll see the explosion of discounter-gym commercials, radio ads about dedication, and daily articles about weight loss on Facebook.
But what type of diet has shown the most success?
Over the years, there has been a war between two major diets: low-fat and low-carb. Well, researchers set out to answer the question of diet effectiveness, between low-fat diets and low-carb diets.
Popular Diets Tested:
- Low-Carb Diet – Dr. Rober Atkins
- Low-Fat Diet – Dr. Dean Ornish
- High-Fat Diet- Mediterranean Diets
After analyzing 53 studies of various diets from low-carb to low-fat, there were no final winners. None. No diet proved to be effective over another diet.
Overall, the diets reflected no differences between the low-fat and high-fat diets. The only difference is that low-fat diets showed about 2.5 pounds more weight loss after a year. But researchers say this is so small as to statistically insignificant.
“We thought (comparing) low vs. high fat diets would help us identify the optimal diet, but it’s clear that just focusing on how much fat is in your diet is not what is going to help address the obesity epidemic,” said Dr. Deirdre Tobias, epidemiologist at Brigham and Women’s Hospital and Harvard Medical School.
Researchers are surprised that of all the various diets analyzed, none showed significant promise. However, despite the lack of weight loss, it’s still recommended to limit saturated fat to 10% of daily intake.
“The main conclusion (of this study) is not that low-fat diets are pretty bad compared to other diets, but that they’re all bad,” said Kevin D. Hall, the senior investigator at the National Institutes of Health National Institute of Diabetes and Digestive and Kidney Diseases.
Average Weight Loss After One Year: 8.5 Pounds
Another finding is that maintaining dedication on the diet is especially difficult. The easy to follow low-carb diets easy to follow may be beneficial in the short run, but after enough time, most participants will fall off the wagon.
Solution to Obesity
Significant, sustained weight loss is possible with bariatric surgery. With bariatric surgery, patients are given a major advantage of restriction or mal absorption. Studies of bariatric surgery efficacy show that bariatric surgery can help reduce excess weight by 60 to 70% – within a year. Bariatric surgery is a permanent, long-term solution to obesity.
