This seems like a different question than most are asking here . . .
Just how LITTLE protein can I get away with eating (not eating) for backpacking for 5-7 days at a time without significantly diminishing performance?
I can load up on protein every 5-7 days if I need to catch up with my minimum RDA? The thread titled "We need MUCH less protein that we’ve been told" referenced an article on the NCBI web site Recommended Dietary Allowances: 10th Edition which seems to boil it down (in TABLE 6-4) to (males 51+), 170lbs (it does not go higher so I wonder if that’s lean BM ) 0.8g/kg or 63g/day.
I could carry a lot less weight if I only needed 63g a day and make up for any possible deficit when I got to a resupply point where I can eat all I want for a day…
Is it safe to go even lower than 0.8g/kg/day for short periods of endurance activity for a few days at a time? The less weight you carry the less muscle strain and the faster one can get to high protein meals . . . .
I wonder if anyone has ever done any studies on short temporary protein deficits for endurance sports.
My LEAN body mass could be as low as 180 pounds but i’m at 198 right now. I plan on hiking with a 600-800 calorie deficit consumption and rely on burning body fat for the difference. I will be intermittent fasting by doing late breakfast and early dinners (eating all day)
In that book referenced above I found "There is little evidence that muscular activity increases the need for protein, except for the small amount required for the development of muscles during physical conditioning (Torun et al., 1977). Vigorous activity that leads to profuse sweating, such as in heavy work and sports, and exposure to heat increases nitrogen loss from the skin, but with acclimatization to a warm environment, the excessive skin loss is reduced and may be partially compensated by decreased renal excretion (WHO, 1985). In view of the margin of safety in the RDA, no increment is added for work or training."
