only if you are a steroid head

You'll have less energy but you'll adapt to it pretty good.

Cardio yes
Weightlifting no

Men perform better empty, women perform better full.

What? It that was the case powerlifters would go into the contest fasted.

Think it's a sex pun

>>36266159
Yes, that is exactly why the old saying goes
"An army can only fight on an empty stomach"

Cardio on an empty stomach has a bad habit of burning more muscle tissue up than cardio after a light breakfast.

did someone paint that suit on him?

Only if your body does not have essential amino acids. You can do cardio in a fasted state and only burn fat, but you should have some form of essential amino acids beforehand. Half a scoop of 100% whey should keep you in a fasted state, and mitigate any muscle loss.

Also, unless your doing like 45 minutes or more of intense cardio, you could probably get away with an empty stomach entirely without any issues. The body will only attack lean mass in extreme cases or when it is in starvation mode.

this

The studies show that there are benefits to training fasted, not competing. Advice is: Train fasted sometimes, but compete fed.

Fasted you'll have less glycogen available in your muscles.

For cardio, the theory is that you will have to rely more on aerobic beta oxidation (fat metabolism) for energy, as you won't have the carbohydrates necessary to rely entirely on glycolytic metabolism.

Not sure on the actual applicability of it. I feel like it might give you a very slight edge on losing fat at best. It all comes down to the degree to which you store glycogen, how depleted you are from sleeping, and your ability to perform at similar intensities in a depleted state. I'm on my phone, if anyone wants to look for studies on Fasted exercise and fat metabolism.
