Multiple dietary pathways can lead to weight loss, and adherence to a weight-loss program is a better predictor for success than the type of eating pattern a person chooses, according to a speaker.

“Every diet is associated with great variation in weight-loss success, and adherence to the diet is the best predictor of success,” Donna H. Ryan, MD, professor emerita at Pennington Biomedical Research Center in Baton Rouge, Louisiana, told Healio. “However, even though we recommend that the choice of the diet involve the patient, there is no evidence that diets based on choice vs. no choice produce greater weight loss. The quality of the diet is important in health improvement.”

Ryan discussed weight-loss diets at the World Congress on Insulin Resistance, Diabetes & Cardiovascular Disease.

Diet adherence associated with weight loss

Research has not found any diet to be best for weight loss. In data published in Obesity in 2013, an expert panel reviewed literature from 17 diets and found no diet was clearly superior to the others for weight-loss duration of at least 1 year. Rather than endorse a specific diet, guidelines instructed providers to reduce calories to 1,200 kcal to 1,500 kcal per day for women and 1,500 kcal to 1,800 kcal per day for men. Additionally, the guidelines stated diets should be based on a patient’s preference and health status.

Multiple studies have found diet adherence is associated with weight loss. A 2005 study published in JAMA analyzed weight change for adults on the Atkins, Zone, WW and Ornish diets. There was no difference in weight change by diet type, but adherence to any diet for a longer period of time was associated with greater weight loss. </…….
