“In a study published in the American Journal of Clinical Nutrition,79 we followed 276 middle-aged adults in Quebec for six years, dividing them into categories based on diet. Overall, the participants gained about 6 pounds (quite typical for this age group), but with huge individual variation—ranging from a 20-pound weight loss to a 30-pound weight gain. For those consuming a high-carbohydrate/low-fat diet, Insulin-30 strongly predicted this variation. That is, people with low insulin secretion gained on average virtually no weight, whereas those with high insulin secretion gained on average more than 10 pounds. In contrast, Insulin-30 had no relationship to weight gain among those consuming a low-carbohydrate/high-fat diet.”
