Military Diet Day One

I've written extensively on the Military Diet before, because it is simple, easy and effective.  I'm trying it again. This is my latest attempt with notes and thoughts.

Breakfast

• One whole grapefruit.  This was a little expensive, it was over a pound, and it cost $1.60.  The official diet calls for 1/2 grapefruit, but I ate the whole thing.  What are you supposed to do with the other half?  Calories: 100.
• Peanut butter.  I looked at the individual servings, but they had sugar in them.  So I bought a 15-ounce plastic jar of natural peanut butter with only roasted peanuts and salt.  It was very oily, and it kept dripping off the spoon.  I ate several spoonfulls, probably 2 ounces.  Calories: 400.
