Scientists have documented the benefits of lactate burning in exercising humans, but few studies have looked at the role of lactate during rest or after a meal. Exercise physiologists challenged fasting men and women with a carbohydrate meal and then monitored lactate in the blood and fat vs carbohydrate metabolism. They found that lactate buffers glucose from a meal, and that lactate is utilized for energy almost as much as glucose.
