Cyclists should tread carefully when it comes to intermittent fasting, say experts – here's why

Leading sports nutritionists and exercise physiologists have issued a cautionary advisory regarding the practice of intermittent fasting (IF) among cyclists. Citing potential negative impacts on performance, recovery, and overall health, experts highlighted risks such as inadequate nutrient intake, hormonal disruption, and compromised immune function, particularly for athletes engaged in high-intensity or prolonged training regimens. The consensus from various specialists suggests that while IF might offer benefits for sedentary individuals, its application in an athletic context requires significant consideration and professional guidance.

This expert intervention arrives amidst a growing trend of cyclists adopting various dietary protocols, often influenced by popular wellness movements rather than sport-specific science. The appeal of IF, promising benefits like weight management and improved metabolic health, has led many amateur and even some professional riders to experiment without fully understanding the physiological demands of their sport. This guidance serves as a crucial counterpoint to anecdotal evidence, re-emphasizing the fundamental need for consistent, adequate fuelling to support training adaptation and prevent overtraining syndrome.

Ultimately, the message is clear: cycling demands fuel, and attempting to outsmart basic physiology with trendy dietary restrictions often leads to suboptimal performance and health. Sometimes, the simplest, most consistent approach remains the most effective.
