Curious about what actually happens in your body when you fast? ⏳
Understanding these stages can help you mentally and physically prepare for what your body experiences during a fast.
From the first few hours after eating to several days in, your body shifts from using glucose → glycogen → fat → ketones, while activating repair and regeneration processes along the way.
Fasting can support:
✨Fat adaptation & metabolic flexibility
✨Cellular repair & autophagy
✨Hormonal signalling for growth & regeneration
✨Mental clarity and steadier energy
⚠️ Remember: everyone’s timeline is different. Entering ketosis can take 2–4 days or longer depending on your body, and prolonged fasts should be done thoughtfully and with guidance especially for women or anyone with hormonal considerations.
Also everyone’s experience is unique. Factors like the type of fast, age, metabolism, activity level, and overall health all play a role.
