Coconut oil is also portable and non-spoilable. I keep a jar in the office.
For a treat, macadamia nuts are basically pure O9 fat.
A small can of cod liver
Something I hate myself, but some people like - the ghee
Home-made bacon (or a branch you trust) - you do need a fridge in your room for it
I suggest investing in a thermos or a cooler if the room doesn't have a fridge. I rarely go for a trip without a thermos (broth, tea), tea bags and a few cans of sardines (I know, I may sound mental!)
Yes, a tuna, eggwhite and spinach/celery smoothie is one of the most satiating things I have ever tried. Spinach may be omitted. I usually do 2 cans of tuna with half a cup or so of egg whites and whatever spice.Does anybody have experience in regards to the ability of protein to satiate in the absence of carbs or fat?
