Camp food.. jerky! Granola,protein powder,nuts,vitamins, cereal,dried fruit,peanut butter(smuckers natural)and whatever bug flies into your plate at the time.
"Pure protein" bars. They have 20 grams protein and not much simple carbs and sugar.They dont cost alot either.
One or two dehydrated meals for me to break up the dry food but they are expensive and are usually not very good for you.
If Iam going to eat sugar I will just bring some dark chocolate bars.
I like those little meo (spelling)? flavoring things for water. Just squirt it in,no mess no fuss.
Instant oatmeal has alot of sugar and wont give you lasting energy,use regular oats,I just eat them raw and dry.
I dont drink coffee but if I did I wouldn't drink it right before bow hunting without cleaning my mouth as it has a strong smell that can stay on your breath.
