Our Story
About FastingCalc
We built this because we were tired of fasting apps charging $20–$30 per month, locking you out after 7 days, and storing your personal health data on their servers.
Who We Are
FastingCalc was founded in 2025 by Alex Morgan, a health science communicator and long-time intermittent faster based in the UAE. After years of paying for fasting apps that locked basic features behind monthly subscriptions, Alex built the first version of FastingCalc as a personal spreadsheet — then rebuilt it as a public tool when friends kept asking for access.
FastingCalc is independently owned. We are not VC-funded. We have no investors, no advertisers shaping our content, and no incentive to recommend products. Our only goal is to give you the most accurate fasting tools on the web, free, forever.
Our philosophy is simple: health tools should be free, fast, and honest. Every calculation runs entirely in your browser. We collect no personal data. We store nothing on our servers. Your fasting schedule belongs to you.
Alex Morgan
Founder & Health Content Lead
Alex has practised 16:8 intermittent fasting for over three years and holds a background in health science communications. Every article on FastingCalc is written or reviewed by Alex personally.

Every health claim on FastingCalc is:
- Linked directly to a peer-reviewed source — PubMed, NIH, or a major medical journal. No claims without citations.
- Written by or reviewed by Alex Morgan — all content goes through a personal review for accuracy and clarity.
- Updated when new research supersedes prior findings — we track major fasting science publications and revise when needed.
- Clearly labelled with a medical disclaimer where appropriate — we never substitute our tools for professional medical advice.
We use the Mifflin-St Jeor BMR equation (Mifflin et al., JADA 1990) for all calorie calculations — the most validated formula for estimating resting metabolic rate.
🔒 Privacy First
FastingCalc runs entirely client-side. No data is ever sent to our servers. Your weight, age, schedule, and fasting history (stored in localStorage for the timer) never leave your device. We use basic analytics (Google Analytics, anonymised) to understand which tools are most useful.
