Is it good to do cardio in the morning on an empty stomach?
Ah…now THE question of the day…is it good to workout on an empty stomach?
Is a fasted cardio session really worth the starvation?
Well, some of you will say you have no choice but not to eat before your workout because if you do eat, you’ll get sick.
Then we have the other group, that’s just the opposite. If they don’t eat, they will get light headed & sick during the workout.
I know we have both parties here, but to the question: are the morning breakfast skippers going to have better results vs those who feel like they must eat?

Yes but no…
I know not the answer you want to hear. You wanted something definite. I know. I am the same way. That’s why I researched this topic.
Here’s the breakdown real simple:
If you workout sans fuel (not eating before), then you can potentially burn 20% more fat.
How??
Well, our bodies want to use the most readily available energy. If we’ve just eaten, it’ll use that fuel to fuel the workout.
If you’ve not eaten, your body is using your existing fat stores for energy.
Sweet, right!?

Well, as with all good things, there’s always a flip side.
This flip side isn’t bad, but you just need to be aware of them.
1. Not eating before means you may not be able to go as hard as you’d like to go.
Which is probably not a bad thing because to burn this 20% more, your cardio needs to be slow and steady. If you do a hard core workout, you’ll dip into not only stored fat but also carbs & proteins (muscle mass…not good. You don’t want to burn muscle mass).
2. You may be hungrier through the day. In my research, it was also noted that those who didn’t eat prior to working out, while they burned more during the workout, they had a tendency to want to eat more the rest of the day vs their counterparts who ate prior to working out.
3. A HIIT workout could burn muscle mass. If you do a HIIT workout, you’ll continue to burn calories throughout the day, but HIIT workouts are tough. So you might not have energy for those, plus you risk burning muscle mass at this point.
However!! (they always have a “however”, don’t they?!)
If you drink something like Energize before, you’ll have the energy you need, and if you have your Recover (some BCAA’s) during or right after, you’ll save your muscle mass.
4. You need to eat after. If you decide to do your cardio without eating before, you’ll definitely need to eat after…pretty soon after.
