Here was a typical day of eating when I was hiking the Pacific Crest Trail. Keep in mind I had been plagued by mosquitoes so I had to eat through a head net. Then I was plagued by rain and couldn't sit down to eat (because I had buttless rain pants.)
This was my day, starting with breakfast:
grape nuts w/ powdered whole milk, nuts, freeze-dried fruit
granola bar/oatmeal bar
Once a week, a whole large packet of instant pudding reconstituted with powdered milk
M&Ms or Reese's Pieces
One layer of Pepperidge Farm Chessmen cookies or one layer of Pepperidge Farm chocolate chip cookies
More candy or crackers
Knorr Pasta Sides with a packet of Alfredo Cheese sauce powder
Chunks of swiss cheese
Once a week I'd add a packet of tuna
One large bag of gummy bears or one king-sized candy bar
That was my planned food. Sometimes unplanned food would appear on the trail, courtesy of people who wanted to help me. I'd drink 1 or 2 sodas if I found a cooler. I'd eat 1 or 2 additional candy bars if I found candy. If there was a restaurant, I would get the equivalent of a Denny's Grand Slam.
I ate this way for three months, twice! A total of 6 months. Is it any wonder my metabolism/insulin sensitivity was toast?
