Calorie Calculator

These calculators exist all over the internet, but the one that I was using while trying to get in shape looked really dated and required clicking the submit button and re-entering data a lot, so I figured I'd rebuild it myself, but make it reactive so it's nicer to look at and easier to use. This utilizes the Mifflin St. Jeor equation.

Enter your data and get your estimated daily calorie intake.
