How this site works

  1. Sources first

    Every number traces to the WHO, CDC, NIH, USDA or a peer-reviewed paper, listed at the bottom of the page. No source, no claim.

  2. Formulas shown

    Every tool prints its formula and its floors: never below 1,200 kcal for women or 1,500 for men.

  3. Dated and corrected

    Each page shows when it was last updated. Corrections are made in the text and noted at the bottom.

  4. Money, plainly

    Ads come from Google and are kept out of our own text. The paid plan is the only thing we sell. We do not sell supplements.
