About

GoodHealthStack is a growing collection of free, single-purpose health and diet calculators. Many official patient handouts explain a rule in words but never give you a number you can act on, or a simple way to track it during the day. Our tools turn that guidance into concrete numbers and easy trackers.

Who writes GoodHealthStack

GoodHealthStack is built and maintained by Akshay Choudhary, its founder. He builds free, single-purpose health tools that turn published clinical diet guidance into simple calculators and trackers. He is not a medical professional; every tool is compiled from cited medical sources and is intended for general education only, not a substitute for professional medical advice.

Editorial standards

Each tool is based on guidance from recognised clinical sources — for example Mayo Clinic, Cleveland Clinic, and the U.S. National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) — which are listed in a "Sources & references" section on each tool. The underlying math is shown in plain language so you can check it, and each tool shows a "last updated" date.

Our approach

Every tool is free, fast, private, and free of sign-ups. This is general information, not personalized medical advice — see our Terms, and always consult your own care team.
