#Fastedcardio

Running before breakfast—once whispered about only in elite sporting circles—has stepped into the spotlight as growing numbers of athletes embrace “fasted cardio” for improved fat burning and performance. This trend, recently highlighted in a widely circulated Men’s Journal report, is now backed by a mounting body of scientific research, offering both promise and caution for Thai runners seeking to supercharge their fitness routines.

For years, the conventional advice handed down to Thai runners and fitness enthusiasts was to fuel up before workouts. However, scientific studies are revealing that skipping that pre-run meal may offer distinct metabolic advantages, especially for activities like morning jogging or moderate endurance training. The heart of the matter: When you exercise on an empty stomach, your body faces depleted glycogen reserves and must turn rapidly to stored body fat for energy. A 2015 study frequently cited in fitness media found that individuals who exercised in a fasted state increased fat oxidation rates over 24 hours, compared to those who worked out after eating (Yahoo Lifestyle). Similar findings were presented in a review published in the British Journal of Nutrition, noting the metabolic shift and greater reliance on fat as fuel during fasted exercise (PubMed).

The latest scientific insights are sparking a fresh trend among runners and fitness enthusiasts in Thailand: lacing up their shoes before breakfast and heading out for a “fasted run.” This approach, often referred to as “running on empty,” is gaining traction globally as new research uncovers benefits that appeal especially to competitive athletes and health-conscious Thais. The core idea is simple—exercising in a fasted state, usually first thing in the morning before eating, might unlock unique advantages for both body composition and performance.
