Note

We are predominantly built on H20 & fat reserves.

Imagine a 140 lb athletic male:

~ 114.8 lbs is built of 70% water & 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, supported by mineral dense fluids.

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.
