Fasting: Intermittent Fasting

Fasting - Intermittent Fasting is more than skipping meals. It's a research-backed practice that changes how your body uses energy. Fasti is a clean, distraction-free fasting tracker built around the methods and metabolic science that actually work. CHOOSE YOUR FASTING METHOD 16:8 fasting (the most popular starting point) 18:6 fasting 20:4 fasting OMAD (one meal a day) 5:2 diet Warrior Diet Alternate day fasting Custom windows from 12 hours up to extended fasts Pick a method, set your eating window, and start. The fasting timer runs quietly in the background and notifies you when each phase begins and ends. WHAT HAPPENS WHEN YOU FAST Your body moves through clear metabolic stages during a fast. The app surfaces each one in real time so you understand what is happening inside, not just how long is left. Hours 0 to 4: Digestion and insulin response Hours 4 to 12: Blood glucose stabilises and glycogen stores begin to deplete Hours 12 to 16: Fat metabolism activates as the body looks for new fuel Hours 16 to 24: Ketosis begins, fatty acids convert to ketones for energy Hours 24 and beyond: Autophagy ramps up, the cellular renewal process the body uses to recycle damaged proteins Research on time-restricted eating points to improved insulin sensitivity, steadier energy through the day, reduced inflammation, and better metabolic markers over time. The app gives you the clarity to track all of it.
