Optimizing your energy levels
Most of us plan our days as if our energy were flat and predictable. It isn’t. Your body moves through natural rises, peaks, and dips over the course of the day, influenced by things like meals, sleep, and recovery. That doesn’t mean you’re “unmotivated” or “undisciplined” when certain tasks feel harder, it just means you’re human.
This tool is a planning sketch, not a medical device. It offers a simple way to visualize how energy often changes across the day and to think about which kinds of work tend to feel easier or harder at different moments. There are no scores, no grades, and no right answers – just a way to make trade-offs visible.
A few important notes:
- This is not medical advice, and it does not model your actual blood sugar.
- The energy curve is a simplified, population-level pattern, not a diagnosis.
- Bodies differ. Days differ. Life intervenes. Check with your doctor if you don’t have enough energy to do the things you want.
Developing a productive routine
Your blood sugar changes over the course of the day. That means the kind of work that feels easy can shift too. Set up your day on the left, then colour your hours. When you’re ready, click Check my plan to see the trade-offs.
