3-4% is what the doctor (Hap Farber) said. Only the caliper test, but still the lowest of the 100 athletes he tested the day before the race. The point is, at a very lean weight (even by ironman-distance athletes) I was borderline "overweight" according to the BMI. (The fourth year I got checked he came and said he had bad news...I was only the second-lowest body fat percentage.:-)

Tri or tri not; this is no du. (--- with apologies to Yoda.) Slow triathlete who survived Huntsville, Lelystadt, Colmar, Fontanil, and
Szekesfehervar/Lake Velence. Arbor hydration specialist in a kid's park in Monterrey 4 times in the 1990s (and in the pits in 1994).

False. Not hard on organs.

Unless you've got kidney issues already, there is no relationship between long-term high protein diet and compromised organ health. If you do have kidney dysfunction already, limit protein per your nephrologist recommendations.

"Not absorbing" protein is a poor argument for being leery of overconsuming it. Worst case, you've consumed some extra protein and you pee, poop, or convert it to something else. No biggie.

Consequence of under-consuming protein: lost muscle. Biggie. (if you care about retaining muscle)
