Research Suggests Fasted Workouts Can Improve Metabolic Health, But Weight Loss Remains Elusive.
When it comes to burning fat during exercise, there's some truth to the idea of working out on an empty stomach. According to Javier Gonzalez, a professor of nutrition and metabolism at the University of Bath, exercising after fasting can indeed result in more fat being burned compared to when you eat breakfast, particularly if that breakfast is high in carbs.
However, it's essential to separate fact from fiction - fasted workouts don't necessarily lead to weight loss. When we exercise, our bodies switch between burning carbohydrates and fat as energy sources, with the proportion of each depending on the intensity and duration of the workout. If you've skipped a meal overnight, your body will generally prefer fat over carbs due to the existing glycogen stores in muscles and liver.
To lose weight, it's crucial to maintain an energy deficit - meaning you burn more calories than you consume. Whether you exercise fasted or fed has little impact on this outcome as your body will balance things out over time.
That being said, research suggests that training in a fasted state can have some benefits for metabolic health. Studies have shown that it improves blood sugar control and enhances how muscles handle glucose spikes after meals, likely due to the increased movement of glucose out of the bloodstream during exercise.
However, these effects are most noticeable with endurance exercises like jogging or cycling rather than high-intensity workouts. For example, during sprint intervals, the body relies heavily on carbohydrates regardless of whether you've eaten a meal or not.
Ultimately, the key takeaway from this research is that exercising itself is more important than whether or not you're fasted. If you want to try fasted workouts, start with short sessions and gradually increase duration as needed. But if you do feel lightheaded or dizzy, it's clear that your body needs some extra fuel - so be sure to stop and eat something before continuing.

I think this is kinda cool, but what about the whole "exercise = weight loss" vibe? 
Like, we've all been told that if we just exercise enough, our weight will magically drop off... but it's not that simple, right? 
If you're not consuming enough calories, your body will just store the fat instead of burning it, no matter what time of day you exercise. And don't even get me started on the whole "your body prefers fat over carbs when fasting" thing - that's just a myth 
. It's all about how your body adapts to the workout intensity and duration. For example, if you're doing high-intensity interval training, your body will still rely on carbs regardless of whether you've eaten or not. So yeah, exercising is important, but don't think you can outsmart a calorie deficit that easily 
.
It's like, our bodies have this automatic switch that kicks in when we fast, makin' us more reliant on fat for fuel. But what if that's not the best approach? What if we're just creatin' a temporary illusion of burnin' more fat?
jogging and cycling are like the 'cool kids' of workouts, but what about the rest of us who need somethin' a little more intense? Are we just gonna be left out in the cold?
fasted workouts are actually a game changer for ur metabolic health! its not about burnin fat but more about how ur body handles insulin & blood sugar spikes 
research shows that endurance exercises like jogging or cycling can def improve glucose control & reduce inflammation 
now i know what u r thinkin "but wont i lose weight if i exercise fasted?" and the answer is kinda...nope 
so yeah, just start with short sessions & listen to ur body, dont be afraid to snack on somethin when u feel dizzy or lightheaded 
. It's all about the energy balance, you know? burn more calories than you consume and that's how you lose weight, regardless of whether you're fasting or fed
