Don't try and complicate things too much. It just not worth it. It will always be the calric deficiet that induces weight loss not the time of your cardio.
Granted that fasted state cardio does tend to burn a higher proportion of fat, you can still do it at any time and have success.
Do your cardio and eat. Eat what you normally would for that time. Simple, don't overthing things, your time is better spent training than on here overanalyzing every detail trust me....
