Research indicates that performing high-intensity exercise in a fasted state can cause the body to burn more fat during the workout, but it also increases the risk of muscle breakdown. The answer to "will I lose muscle if I lift weights on an empty stomach?" is complex and depends on multiple factors, including workout intensity, duration, and overall diet.

Exercising in a fasted state can increase fat oxidation during lower-intensity activity, leading many CrossFit athletes to question if training on an empty stomach is beneficial. This practice has its proponents and detractors, with significant impacts on energy levels, performance, and recovery that are crucial to understand before you skip your pre-workout meal.

According to a 2024 meta-analysis, exercising in a fasted state can cause a metabolic shift, increasing fat oxidation during low-to-moderate intensity workouts. This ability to use stored fat for fuel is a key reason some individuals feel they **workout better when they don't eat**, experiencing a sense of lightness and greater efficiency.

While fasted cardio is often praised for increasing fat oxidation, research suggests that high-intensity resistance training on low fuel can significantly compromise your performance. So, **should I lift heavy weights on an empty stomach?** This is a critical question for those focused on strength, and the answer depends heavily on your goals and how your body responds.

Research indicates that exercising in a fasted state can enhance fat oxidation, but for high-intensity activities like CrossFit, the effect on performance and muscle preservation is complex. This raises a key question for many athletes: is it good to workout crossfit fasted in the morning? The answer depends heavily on your specific goals and how your body responds to training on an empty stomach.
