We are predominantly built on H20 & fat reserves.
Imagine a 140 lb athletic male:
~ 114.8 lbs is built entirely on 70% H20 & 12% fat reserves.
~ 25.2 lbs would then be the total mass of what actually needs to be “fed”.
These few active lbs should be fed rich sources to fuel our Human; water is fundamentally the silicon transmission source of all activity: mineral dense & glass bottled.
Adult men (normal weight > 65yrs) ~ 60%
Adult women (normal weight > 65yrs) ~ 50% - 55%
Highly lean (athletic) ~ can approach 65% - 70%
1L = 2.205 lb
1KG = 2.205 lb
Thirst, urine color, and body mass change are better guides than any fixed number.
Total daily “baseline” loss ~ 2.2 - 2.8 L
Exercise, hot, humid weather ~ 3 - 4 L
(elite athletes > 10 L)
Men ~ 12 - 24%
Women ~ 25 - 31%
Varies by sex, height, age, and ethnicity.
Thoughts
1 – 9 hours — Metabolism & first half‑life
Because of genetics and health factors, half‑lives as short as 1.5 h or as long as 9.5 h have been documented.
10 – 15 hours — Two & three half‑lives
After two half‑lives roughly 25 % of the original caffeine remains; after three, about 12 %.
Many people are still sensitive to this amount, which is why sleep researchers study the correlation of rest stability.
