As for BMI:
Back in the Marine Corps, the body builders were often on weight-waivers. It was idiotic that someone who was clearly physically fit, could always pass a PFT, and could bench press a small car had to go yearly for physical waivers. I knew a few guys that had to have their BDU's tailored to fit their guns....and yet if you looked in thier SRB you'd just see 'weight waiver'.
BMI is useless in my book unless you apply it directly to each and every person's individual traits and physique.
I had a similar problem in the Rangers, but no waiver for jfruser(1). I am a broad, heavily-built man to begin with. At 6' and 200lbs, I look (in the words of my wife) like a "bone." I put on another 25lbs(2) of muscle, got "tape tested," and was counseled on how I was "overweight." This was directly after a ruck march during which I drove everybody into the ground with my pace and I was able to tote more than anyone in the unit.
I just had to get so effing lean at 225lbs, I tested at ~5% using the skinfold method at the local Gold's Gym. At 5% skinfold body fat, I was
barely under the "tape test" limit (neck & hip circumference and height).
I knew several guys who used pharmaceuticals to aid their efforts, but I shied aways from them. Pretty damn annoying when one of those guys who was juicing is in the room while you're getting crap for being "overweight."
(1) My first & third XOs didn't care. I did well at PT and they appreciated having a guy around who could move *expletive deleted*ss and a heavy ruck at a brisk pace. My 2nd XO, OTOH , was a right bastard, what with his dishonesty and other personality deficits.
(2) During this time, I got into hot water for permanently bending one of the olympic bars in the weight room. I can't recall if it was doing squats or bar shrugs. None of the juicers managed
that trick.
The trouble with eating healthy though, is produce. Grains and legumes are quite affordable, but ample amounts of fresh fruits and vegetables are not.
Also, they spoil so dang quickly. I have pretty much just assumed I am going to pay through the nose for produce and that a significant portion will go bad before it is consumed.
