My clients- a group of 11 spanish guests eat Yak Steaks for every dinner & lunch during the 17 Day's Trek to Gokyo- Cho La Pass- Everest Base Camp last year in october. I advised them not to eat the meat-foods because it is forbidden to kill any animals in the Everest National Park Area. But my guest/spanish peoples told me that they want to eat Yak Steak because they need more power & energy.

It would be good to know about does the food- Yak Steaks give more power/energy?
