Kenny hikes all along the road in a day at a steady pace, on a backpacking trip, covering 30 km and burning 4000 calories.
Backpacker Magazine informs a simple calorie estimate based on human body weight and the general extent of the intensity of the daily activity.
For a day of a lot of strain of backpacking with a “heavy” pack and normal weight range, it is suggested that 25to 30 calories per pound of body weight are lost.
Using one’s 185-pound self-weight as a proxy, calorie consumption figure comes at 4,625 to 5,550 calories.
