The classic 2 p.m. energy dip is rarely a lack of coffee. It's often your blood sugar riding a rollercoaster, and over time that costs more than a tired afternoon.

- Large blood-sugar swings cause energy dips, hunger and poor focus.
- Persistently high levels raise the risk of type 2 diabetes and cardiovascular disease.
- HbA1c shows your average over roughly three months.
- Meal order, composition and movement stabilise the curve.
What do we measure?
HbA1c reflects your average blood sugar over the past few months. Together with fasting glucose and insulin it gives an early picture of your metabolic health, long before a diabetes diagnosis.
Why stability matters
Every big rise and subsequent fall costs energy and focus. Repeated over years, it contributes to inflammation and insulin resistance.
How to keep the curve flat
- Eat protein and greens before starch
- Avoid liquid sugar
- Walk for 10–15 minutes after meals
- Prioritise sleep
Frequently asked questions
Do I need a continuous glucose monitor?
For most people, HbA1c and fasting values are enough. A CGM can give insight for a period, but is rarely necessary.
Is this included at Aevia?
