What to eat?

There is a significant difference in sitting at a desk for eight hours and standing and walking around for eight hours. Merely standing burns 800 calories pretty easily.

At 49 years of age 5'11.5" tall and 185 pounds my RMR for sedentary is 2081 calories.

At work it becomes very apparent when I do not have enough food. My energy levels drop and I feel fatigued and lethargic.

I need to find brown bag foods that will last a week in the fridge, that give me good quality energy at a reasonable dollar. Further they should be easily consumable in a 10 minute period and have approx. 300 calories.
