7 Ketogenic Diet Improves Exercise Response in High Blood Sugar Conditions¶
Researchers at Virginia Tech found that a high-fat ketogenic diet helped mice with elevated blood sugar normalize glucose levels and dramatically improved how their muscles responded to exercise, enhancing oxygen utilization and endurance capacity. The study, published February 25 in Nature Communications, suggests diet and exercise may work synergistically to improve metabolic health in ways previously underappreciated.
- Study published Feb. 25, 2026 in Nature Communications by Virginia Tech researcher Sarah Lessard
- Mice on ketogenic diet normalized blood sugar within one week, eliminating hyperglycemia symptoms
- High-fat diet caused muscle remodeling, increasing slow-twitch oxidative fibers and aerobic exercise capacity
- Ketogenic diet improved exercise-induced oxygen uptake, typically impaired in people with high blood sugar
