Here you guys have a really good tip if you wanna lose fat quick.

After bootcamp in army ~3 months my platoon went for a excersise that would give us our wanted beret.

It was a painful 5 days excersise with 75lbs pack + 10-20lbs weapon + radio and additional equipment + full body armour.
We walked/runned for and average 16hours a day. 5 hours of breaks/food-making/etc and about 3 hours sleep every day.

It was painful but OMG when we got back to barracks. I noticed i could move a lot faster, i felt better, I wasnt tired, and wtf is that six-pack on my belly. We all had gotten so ripped. I dont know how much fat we burned but it was A LOT. And actually it was a pretty funny/interesting fat-burning excersise. But we all ruined it by ordering pizza 4 days in a row later.

So my advise to you. Buy a good back-pack, tent, good army-boots(they are the best) and fill up with equipment until you have so much you can carry for a long weekend or so. (I would guess 60lbs is would be good enough for most ppl). And then start walking, in mountains or whatever. I have never liked nature before, but you really learn how to enjoy how good it feels to eat, sleep, shit and walk around in forrest/mountains.
Anyway, I am doing this again when I am cutting.
