Nutrition myths

“Detox” is a marketing word, not a body process

Your liver and kidneys have been doing this your whole life, for free.

No juice, tea, powder or three-day programme detoxifies you. Your liver and kidneys do, continuously, without instruction and without a subscription.

The word borrows medical authority it hasn't earned. In actual medicine, detoxification refers to specific clinical processes — treating poisoning, managing withdrawal. It does not describe drinking cayenne and lemon for three days.

What a cleanse actually produces

A few days of substantially reduced intake. Some water loss, which shows on the scale and reads as progress. Frequently a headache, low energy, and difficulty concentrating. Then, when normal eating resumes, a rebound — because a few days of severe restriction is not a change to anything.

Feeling different is not the same as being detoxified. Under-eating for three days will reliably make you feel different.

What genuinely supports the organs doing the work

This list is unglamorous, which is precisely why nobody sells it:

  • Water. Kidney function depends on adequate hydration.
  • Fibre. Keeps things moving and supports the gut. Vegetables, fruit, whole grains, beans.
  • Sleep. Underrated in almost every conversation about health.
  • Going easier on alcohol. The liver is the organ in question. This is the single most direct lever there is.

That's the list. It costs nothing, and there is no version of it that retails for eighty-nine dollars.

One thing worth taking seriously

If you feel persistently unwell, exhausted or foggy, that deserves a proper look from a clinician — not a cleanse. Those symptoms have real causes worth identifying, and a juice programme will delay finding them.

General nutrition information, not individual medical or dietary advice. If you have a medical condition, are pregnant, or take medication that interacts with diet, talk to your own clinician or dietitian before making changes.
