When it comes to weight loss, neither a low-fat nor a low-carb diet is superior, say researchers at Stanford University School of Medicine. The key to losing weight is simple, eat less.
Previous studies showed that several factors, including genetics, insulin levels, and bacteria in the digestive tract – called the gut microbiome – can affect weight loss. For this study, published in JAMA, researchers focused on genetic makeup and insulin to determine if these factors play a role in determining whether a low-fat diet or a low-carb diet is better for a certain individual.
The study involved 609 people between the ages of 18 and 50, about half of whom were women and half men, randomized to follow a healthy low-fat or healthy low-carbohydrate diet for one year. Researchers collected comprehensive data and discovered no difference in the success of either eating plan over the other.
