Yes — intermittent fasting (IF) offers several potential health benefits, backed by research and user experiences in Lasta.
Key Benefits
- Improved insulin sensitivity and blood sugar control.
- Promotion of fat burning and weight management (by naturally reducing calorie intake and encouraging use of stored fat).
- Enhanced cellular repair (autophagy) and reduced inflammation.
- Potential improvements in energy levels, mental clarity, mood, and cognitive function (especially once adapted).
- Better metabolic health overall.
How Fasting Works
During fasting windows, your body shifts from using glucose (from recent meals) to burning stored glycogen and then fat for energy. This leads to ketosis (using ketones as fuel), reduced insulin levels, and processes like autophagy (cellular cleanup). Sleep naturally extends your fast, making longer windows easier (e.g., finish eating at 8 PM, start at noon = 16-hour fast including ~8 hours sleep).
Mental Health Impact
Many users report better focus, reduced brain fog, and improved mood after adaptation (due to stable energy from ketones and lower inflammation). However, initial adjustment may include temporary fatigue or irritability—consistency and hydration help.
Individual results vary based on metabolism, lifestyle, and consistency. Approach fasting gradually, and consult a healthcare professional before starting, especially with health conditions.
In Lasta, customize your schedule easily: Tap the duration button (e.g., '14h') in the upper-right of the Fasting tracker → select a new plan → Confirm. This lets you experiment to find what suits you best.
