I've been pondering for a while what food to take with me on the road. Sugar and carbohydrate foods are just out for me as they push me into hypoglicemia anyway. Up to now I've taken no food at all, just plain water and after an hour I will tire a little and after two hours I just hit the wall.
Anyway I just did what I was contemplating doing and took thin slices of raw, salted beef fat!
It worked a treat! Two and a half hours later I powered home with energy to burn and that's a first. The beef fat I buy is biodynamic which I usually render for use in pate. I cut small thin pieces and salted both sides with celtic sea salt and used it fresh rather than letting it dry out. It's a bit chewy but works a treat. Something else to consider is that I know my supply of biodynamic beef is grass fed so it's high in omega 3 fatty acids. The comercial stuff most of you Americans get is grain fed and therefore rich in omega 6 fatty acids which wont fuel you as well as omega 3's.
