I went to Sapper school in November/December of last year and it taught me a lesson about eating. We eat way too much. When they starved me in the woods, I had energy to stay up for the 23 hours per day we were forced to stay awake and I never had the afternoon energy crash we suffer as regular soldiers or Americans. The great thing is that my weight (at 34 years old) returned to that of my high school days and I was very strong and energetic (after recovering from the frost bite, blisters, and all that comes from a very tough school in the Army).
Did my ~9 yrs active with the 58th Combat Eng Company, 11th ACR - then A & C Co., 91st EN BN, 1CD. Hooah!
More to the weight topic . . . I'm now working to lose the 55+ lbs I added since I left active duty in Dec 1998. Ugh.
