The Future of Fasted Cardio: Trends and Expert Insights
The practice of exercising on an empty stomach, often referred to as fasted cardio, has long been a topic of debate in the fitness community. While some tout its benefits for weight loss, others warn of potential pitfalls. As fitness trends evolve, let’s explore the potential future trajectories of fasted cardio and what the experts have to say.
The Pros and Cons of Fasted Cardio
The concept of fasted cardio revolves around the idea that by exercising on an empty stomach, your body turns to fat stores for energy. A study from Nottingham Trent University found that fasting before exercise increased the local fat oxidation rate. However, the same study noted that fasted exercise can lead to reduced performance and enjoyment due to low energy levels.
Alexander Rostte, Coordinator of the Athletic Science Program at the New York Institute of Technology, echoed these findings. He explained that while fasted exercise may burn some body fat, it could also reduce overall fat combustion in the long run. A 2022 study supported this, showing that individuals who fasted for seven hours after evening exercise performed worse than those who did not fast.
Risks and Safety Concerns
Exercising on an empty stomach can pose several risks, including hypoglycemia and dehydration. Without sufficient energy, the likelihood of dizziness, fatigue, and even injury increases. For instance, using heavy equipment with insufficient energy could lead to mishaps. Addionally, fasted exercise can cause muscle loss, lowering your basal metabolism and making weight loss more challenging. Experts advise starting your exercise regimen after consuming light snacks to mitigate these risks.
Personalization and Special Considerations
While fasted cardio may not be universally beneficial, it can be effective for certain individuals. Those with high visceral fat or a balanced muscle-to-fat ratio may find it particularly advantageous. However, it’s crucial to note that people with diabetes or blood sugar control issues should avoid fasting before exercise, as it can lead to increased blood sugar levels due to elevated cortisol, a stress hormone.
Morning Exercise and Preparation
Particularly for morning workouts, it’s essential to prepare your body. Given that morning body temperature is lower and joints and muscles are more rigid. A study by the U.S. Department of Health and Human Services emphasized the importance of warm-up and stretching routines to prevent injuries. Ensuring that the body is well-prepared can mitigate some of the risks associated with fasted cardio.
