When it comes to cardio for FAT LOSS i’m personally not a fan of doing cardio first thing in the morning before eating at least a small balanced meal.
Some people on the other hand love it & tolerate it well.
The most important thing to understand in relation to cardio for fat loss is that when we do it is irrelevant, energy balance dictates the rate of change we achieve.
Training is that fasted or not there is no difference (AT ALL) to the results you will achive
Obviously if we feel better, are time restricted or prefer training before or after food it’s best to go with what feels right for you not what someone else recommends you do.
