7 Ketogenic Diet Improves Exercise Response in High Blood Sugar Conditions, Study Shows

Researchers at Virginia Tech found that a high-fat ketogenic diet helped normalize blood sugar in mice and dramatically improved their muscles' ability to use oxygen during exercise. The study, published in Nature Communications on February 25, 2026, suggests that diet and exercise may work synergistically to improve metabolic health, particularly for people with elevated blood sugar.

  • Mice on a ketogenic diet normalized blood sugar within one week, eliminating hyperglycemia-like conditions
  • Ketogenic diet caused muscle remodeling, increasing oxidative capacity and slow-twitch endurance fibers
  • High blood sugar normally impairs the body's ability to gain oxygen-efficiency benefits from exercise, which the keto diet appeared to reverse
  • Study led by Sarah Lessard at Virginia Tech's Fralin Biomedical Research Institute
