Unknownfavor,
I too am 6'1.15" and my peak weight was 340. I am now2 down to 6'0" and 276 pounds.
I too was employed in the security field, corrections to be exact.
I lost the weight by 2 things:
1. Finasteride - It blocks the conversion of testosterone into dihydrotestosterone, which is 8 times more powerful in putting meat on the hoof. I can definitely feel the muscle loss in my upper body and less so in my legs.
2. Serious dieting - Over 75 % of my diet is vegetables. I am loosing about 1/2 pound a day, maybe a little less. On the day I cheat a little or go out to eat, I gain 2 to 3 pounds back, which takes me another week to lose.
Also, light exercise is helpful, but put away those barbells. Do lots of abdominal crunches and waist turns and bends. Cardio work will speed things up a bit.
Good luck.
