Just a little thought, in reality, how many of us really need 3000 calories a day?
Looking at the San, who don’t seem to spend more than 4’ish hours a day working, planning on working smarter than harder would seem appropriate.
We should probably ask Selco how much of the day was spent exerting oneself versus downtime spent repairing things? Especially as many of us won’t be cutting cords of wood each day or humping the mountains of Afghanistan. And as most of us could probably stand to lose 10, 20, 30 pounds, a 2000 calorie diet may be highly beneficial.
Comparing ourselves to soldiers age 20-25, or lumberjacks who are active for half the day literally, is definitely almost comedic for some. Personally, I walk somewhere between 5 and 12 miles a day, depending on what I am doing at work, and somewhere between 15 and 25 staircases before noon. Yet I am probably 20 pounds “overweight” by the charts. I enjoy what I eat.
In all honesty, most of us won’t be working like draft horses, and won’t be needing as many calories as some expect. Thats a good thing as our stores will last longer.
But to each his or her own.
