How long do you do cardio and what do you do for heavy weight loss?

Wrote all this due to the mod’s. Only the first paragraph is important.

I’m 23m and let myself go 3 years ago and now weigh 223p (26% BF) at 5’9. My goal for now is to get to 190-200p in 3 months if realistic and work my way back down to 170 slowly after that goal.

I don’t have the stamina to run 2-8 miles like I used to when I was 16-19yo, not even 1 miles due to my horrible life choices during the time…..So my cardio for the meantime has been jump roping at home to build some stamina again with some arm/chest and ab workouts. Including personal diet changes.

Any advice or recommendations from anyone? Has anyone lost 30 pounds in 3 months or less if possible?
