Why it matters
Your body processes the same food very differently at different times of day. Insulin sensitivity is highest in the morning and decreases through the day — meaning a carbohydrate-rich meal at 8am produces a different blood sugar response than the same meal at 8pm. Cortisol levels, digestive enzyme activity, gut motility, and liver metabolism all follow circadian rhythms that mean meal timing is almost as important as meal composition. If you notice that the same food feels completely different at different times, you're experiencing your body's circadian metabolic rhythm firsthand.
When Normal helps
Normal tracks not just what you eat but when, and connects that to how you feel in the hours after, over time. It finds your personal optimal meal timing for different types of food — when carbohydrates feel best, when protein is most beneficial, and when eating feels most natural for your body's rhythm.
How Normal finds it
Tell Normal what you ate, when you ate it, and how you felt after. Over a month it finds the timing patterns that consistently produce the best post-meal energy and wellbeing for your body specifically.
