depends.

If you workout on empty stomach in morning you burn twice as many calories because your body has nothing to immediately burn so it goes for the glycogen and the calorie-dense fat.

However, it's also not so good to be burning alot of calories on empty stomach because at a certain point your body switches again from burning fats and thinks you are like in survivor mode so it saves the fat for when you might really need it, and instead starts burning your muscles (if like you didn't eat all day and went and worked out)

Not to mention that it can be very dangerous for your blood sugar if you are exerting yourself alot without any fuel. Might faint, get headaches. Dizzy and lightheaded.

Basically I use to run on empty stomach during my hardcore cutting phase when I lost 65 pounds, now I refuse to workout on empty stomach because I felt like although I lost a ton of weight -> more than I wanted was muscle and i think maybe that could have been avoided if I worked out after eating instead and just lost weight alittle more slowly.

my 2 cents
