SparkFast is a science-based fasting tracker designed to help you follow intermittent fasting and prolonged fasting safely, confidently, and sustainably.

Whether your goal is weight loss, fat burning, improved metabolic health, more stable glucose, or increased energy, SparkFast provides a clear and intuitive fasting tracker with the guidance and motivation needed to stay consistent over time.

🔬 Science-Based Intermittent & Prolonged Fasting

SparkFast is built on evidence-based fasting principles, metabolic science, and behavioural research.
Use the fasting tracker to follow your fasting schedule, monitor progress, and understand how fasting affects weight, glucose, sleep, and energy.
