Yes cause this people lazy to read and do research so they just simply put there "cardio must". Their knowledge is limited.

OP,

1. cardio can make fat lost faster by utilizing more energy.

2. Cardio is healthy whereby it increases stamina and heart health.

OF COURSE no. Just eat below your TDEE. Fat loss is all about calories in and calories out. It's basic energy physics actually.
Adding on to what kshen said, you need recalculate your TDEE after losing around 2kg of fat. This is because your TDEE will become lower as you lose fat since you are getting lighter.
