The Fastimer plugin for Obsidian is designed to help users track their fasting intervals. It allows you to easily add a code block to your notes that tracks the start and end times of your fast, displaying elapsed and remaining times along with a progress bar. The plugin visualizes fasting zones such as anabolic, catabolic, fat burning, and ketosis phases, and updates dynamically as you edit the block. You can customize the fasting duration, and mark the fast as finished with the current date and time. This tool is ideal for those looking to monitor intermittent fasting directly within their Obsidian notes.
