Normally, you will be eating healthy balanced meals that are easily available on the trail based on your properly scheduled itinerary. Losing about 7 to 10% of body weight is a common phenomenon for hikers, but it all depends on the appetite and some other factors. To compensate with the weight loss, most seasoned trekkers manage to eat a healthy diet, sleep adequately well and acclimatize their body well with the altitude. We always encourage all climbers to eat as much as possible for which we provide a perfectly balanced meal and sleep properly as well to get ample rest.
