I know it's kind of a broad question. But, what do you all think from experience? I lost a bit of weight before and it went very fast. I ran a EC stack and lost right around 20 pounds in a month for 2 and a half months, I lost over 40 pounds in that time. That was on a 1500-2k cal a day diet and 45 minutes of cardio 4-6x per week.
Back then I didn't even consider muscle loss. When I was done, I didn't even notice any muscle loss really. My lifts all dropped my about 5Lbs though, so there had to be some.
But, is this a good idea or that is just too much too fast? From what I hear you want to do about 2-3Lbs a week.
