The Science Behind Fasted Workouts: Can Burning Fat Be a Good Thing?
When it comes to working out on an empty stomach, the idea is that you'll burn more fat as fuel. And according to Javier Gonzalez, a professor of nutrition and metabolism at the University of Bath, there's some truth to this claim.
Gonzalez explains that when we exercise, our bodies use a mix of carbohydrates and fat for energy - but if we've fasted overnight, we tend to burn more fat and less carbs. This is especially true for endurance exercises like jogging or cycling, where the body relies on stored fat for fuel.
However, it's essential to note that the benefits of working out in a fasted state aren't solely about burning fat - they're also about improving overall metabolic health. Research suggests that training when your stomach is empty can help muscles adapt better to exercise and improve blood sugar control.
In particular, fasted training seems to encourage glucose to be released from the bloodstream, which can lead to improved energy stability after meals. However, these benefits are modest and not dramatic enough to make fasted workouts a magic solution for weight loss.
Instead, Gonzalez emphasizes that the most important thing is simply getting in the exercise itself. Whether you do it on an empty stomach or with food in your belly, the benefits will be similar - as long as you're creating an energy deficit by burning more calories than you consume.
