Calorie Calculator

Most people guess how much they should eat, and most guess low. Calorie Calculator puts a working calorie calculator on any page of your site: a visitor picks female or male, sets age, height and weight with a slider or by typing, chooses how active they are, and sees the calories they burn in a day. The number comes from the Mifflin-St Jeor formula for resting burn, multiplied by one of five activity levels, so it is the TDEE figure coaches already work with. It suits personal trainers, nutritionists, dietitians, gyms, yoga and pilates studios, and anyone who sells meal plans or coaching. In the editor's Settings panel you set metric or US units, calories or kilojoules, the starting values, the title, the number format, the colours and the font. It works with zero setup and fits narrow phone screens. Nothing a visitor types is sent anywhere or stored, and the script is small and loads after your page. Premium adds a lose, maintain or gain switch with the expected change per week, daily protein, carbs and fat in grams with three splits to choose from, and a button to your own page, such as Book a consultation. Premium also removes the small credit line under the calculator.
