I'm not sure what you are really asking. Are you just wanting to know if anyone exclusively eats meat while cycling? Or are you wanting to know what others that have meat as a majority of their overall diet do while they are on their bikes? Which is probably different things just like the rest of us.
If you are amenable to eating bananas for your diet, then they have a lot going for them. Before I started using other things for energy replacement I use to cut bananas into pieces and put them in a plastic bag that I could easily fish the pieces out of while riding. Popped one in my mouth every 15 minutes and from what I remember, the energy replacement and curve for how long I felt the boost was about as good as what I use now.
