About HealthGood

Our mission

To make trusted, plain-English health information accessible to anyone with an internet connection — without paywalls, signups, or pushy marketing. We want readers to leave HealthGood understanding their numbers, not just seeing them.

Who we're for

Adults in the United States, United Kingdom, and beyond who want to understand body metrics, nutrition, hydration, sleep, and fitness using tools and information grounded in current public-health guidance.

What we do

• Publish free calculators that perform every calculation locally in your browser.
• Write evidence-based explainers that cite the formulas and guidelines we rely on.
• Update calculators and guides as guidance evolves.
• Disclose limitations openly on every tool page.

What we don't do

• We don't diagnose, treat, or claim to cure any condition.
• We don't sell or share the values you enter into our tools.
• We don't accept payment to feature, ignore, or alter editorial coverage.
• We don't recommend medications, prescriptions, or specific clinical interventions.

Our commitment to evidence

Every calculator references a validated formula (Mifflin-St Jeor, U.S. Navy method, WHO BMI cut-offs, Karvonen heart-rate reserve, and others). Every guide cites public-health sources such as the WHO, NHS, CDC, and peer-reviewed nutrition and sleep research.
