I'm planning to take a risk next week of setting my hair into telogen effluvium (system shock shedding cycle) by going through an insane cardio and protein cutting regimen for a month. Maybe two.
Just a bare minimum of protein to keep my hair and some essential functions. Vegetarian and carbs will constitute the bulk of my calorie intake.
And yes, lots and lots of cardio - running, speed roping, elliptical. At the end of each workout I'll wreak of ammonia from burning muscle protein.
I want to get my weight down from 124 to around 116. I'll lose lots of body fat and approach being 'ripped' but I'll lose muscle as well. I can always eat up again and regain the body fat. The end result should be a sleeker body. With the anti-androgens this should make the effort harder

But faster as well.
