Not 10k The US Army determined “heavy exertion” needs 4,500 calories. Something like that. And when they classify “heavy” exertion, they know what they are talking about. The USDA 2000 calorie RDA is intended for moderately active individuals, most people can easily gain weight with those numbers, especially elderly or sedentary.

Except the military diet is no where near the activity level of the old time [ late 19th and early 20th century ] loggers, nor is the food they consumed anything like a modern diet the military estimate is based on.
If you had ever worked in the woods or been a commercial fisherman, you would know the truth of the 10k calories needed. Its not just the falling of the trees, its walking through heavy brush uphill carrying the saw, your food and water, for 10-12 hours a day, 6 days a week.
Go watch an episode of Timber Titans or The Last Woodman and spot the fat faller or Deadliest Catch and spot the fat deckhand.
Hold on just a second here Hoss.
You’re claimimg I don’t know anything about the “Truth” here, because I wasn’t a Logger.
You were a Logger, then I take it? And can personally vouch for 10k calories daily? See where I’m goin’ with that?
I call bullshit on that anyway. At least the Army studies were a methodical, scientific approach trying to determine what it takes to feed an Army. I can tell you from personal observation that the Infantry as a class and the special ops guys in particular have absolutely insane work loads in the field. And 4 to 5k calories probably isn’t enough, the numbers are approximate and just barely sustain them. From what I saw they don’t even have the time to eat enough food.
