Why water matters more in a deficit

Mild dehydration reads as hunger and fatigue — the two things most likely to break a weight-loss week. Hitting a water target is the cheapest adherence tool there is.

Ranges, not rules

Heat, medications, and some heart and kidney conditions change fluid needs — if that's you, your target is a clinician question.

30-second check

See if the program fits you

Two questions. No email required, no commitment — just a straight answer about whether we can see you, before you give us anything.

First — where do you live?

We check your state first because our clinicians can only treat patients where they're licensed. Nothing you enter here is stored or sent anywhere.

Quick numbers — height & weight

Only used to compute your result in your browser — never sent or stored.

This is an eligibility signal, not medical advice or a guarantee of treatment. A licensed clinician makes every clinical decision after reviewing your full intake, and approval is never guaranteed.

Good questions

Asked before starting

Does coffee count?
Mostly yes — caffeinated drinks still hydrate, though water should carry the load.
Can you drink too much?
Yes, though it's uncommon. Extreme intakes — or fluid limits from a medical condition — belong with your clinician.
