FAQ
5Short answers to common questions about calculations and interpretation.
Can I drink too much?
Yes, excessive water can wash out electrolytes.
Are sugar-free drinks okay?
Yes, but water should remain the base.
Why is morning weight higher even with good hydration?
Weight shifts also reflect sodium, sleep, and carb changes.
Should I drink on a fixed schedule?
A schedule helps, but adjust by thirst and activity level.
Should I count water from food and drinks?
Yes. Some fluid comes from food, tea, coffee, and other drinks. The calculator gives an estimate for total daily fluid intake, not only plain water.
