FitHealthRead is a free, fully client-side fitness and nutrition website that combines two things in one place: evidence-grounded articles and instant health calculators. Readers get straightforward writing on training, recovery, mental health, and food including deep dives into individual foods that break down their calories, key vitamins, and what each vitamin actually does in the body, all cited to official sources like USDA FoodData Central and the NIH Office of Dietary Supplements. Alongside the content, FitHealthRead offers four calculators BMI, calorie needs (BMR/TDEE), ideal weight range, and a combined body-metrics dashboard that run entirely in the visitor's browser. Nothing typed into them is ever sent to a server, there's no account to create, and no premium tier gating the results. The site is built as a modern React single-page application with a distinct editorial design (not a generic template), full dark mode support, and a mobile-first responsive layout. It ships SEO-ready out of the box per-page metadata, Open Graph and Twitter previews, structured data for rich search results, and a sitemap so it's ready to be indexed and shared from day one.
