Is doing cardio at the gym on an empty stomach really more effective for burning body fat?

Lately, it's been really hard to find time in the evenings, so I'm planning to wake up a little early before work in the morning and go to the gym.

I looked it up online, and opinions were divided: some said that doing cardio on an empty stomach without eating anything at all is the best way to lose weight, while others said it actually leads to muscle loss and that I should eat something, even if it's just a little. So I wasn't sure which one to believe.

I’d like to ask for advice from those of you who consistently work out in the morning. Is there actually a significant difference in perceived body fat loss or stamina between doing cardio on an empty stomach and doing it after eating something? I would appreciate some tips from those who have experienced this.
