I did a routine once for two months which is the following, I fast three days, eat, fast three days(starting from the day after I eat).
I started at 113 Kg and ended up at 92(low body fat for my height/muscle mass)
I trained 6 times a week, and my training was PowerBuliding, which is dong powerlifting lifts then some isolations to hit specific muscles, so I was doing Deadlifts, squats, bench press, overhead press, rows and what have you. All row and heavy.
I was lifting stupid heavy weights and felt like a god for the whole two months.
I also was walking 15k steps at least daily.
For the day I eat in, I eat big big meals so 6000-8000 calories, and with tons of carbs , protein and fat.
I highly suggest trying this routine out but make sure you refeed big especially carbs, and take electrolytes.
Good luck!
