@Beestung no i never done it
Id love to do fasted cardio but still getting sleepless nights with my son and life is busy and my job is also manual and physical so i dont really "need cardio" i think i burn enough calories, il add cardio when i stall.
Its hard to say exactly whats classed as dropping fat fast, if your cycling and dropping 1lb a week fat thats good but its hard to judge by weight as your gaining muscle etc
Its best getting accurate bodyfat % measurements done every week to see if your fat is coming off, and compare pics as well
Being on cycle and monitoring your weight for fat loss will be total guessing as your weights going to be jumping all over if not going up
