Keeping Your Blood Sugar Steady Through the Day
Blood sugar that swings up and down leaves you tired and ravenous, and over time it damages your blood vessels. Even the order you eat your food in makes a difference.

After every meal, blood sugar rises and is then brought back to baseline by insulin. The more refined starch a meal contains, the higher the peak and the deeper the drop that follows — that is the moment you feel sluggish and crave something sweet in the middle of the day.
The numbers commonly used
- Fasting blood sugar: 70–99 mg/dL is normal; 100–125 suggests prediabetes; 126 and above needs a repeat test to confirm
- Two hours after a meal: below 140 mg/dL is normal
- HbA1c reflects the average over 2–3 months: below 5.7% is normal; 5.7–6.4% is prediabetes
These numbers only mean something when a doctor reads them alongside your medical history — do not diagnose yourself from a single reading.
What to eat, and in what order
With the very same meal, the order in which food goes into your mouth changes how high your blood sugar peaks.
- Eat vegetables first, then protein and fat, and only then rice and starchy dishes
- Favour whole grains: brown rice, oats, sweet potato, wholegrain bread
- Always pair starch with protein or fibre; do not eat it on its own
- Drink plain water instead of soft drinks and juices; juice has lost its fibre, so the sugar is absorbed very quickly
- Eat fruit whole, and choose less sweet fruits such as guava, pomelo or apple
Factors few people expect
Lack of sleep and prolonged stress raise the hormone cortisol, which pushes blood sugar up even when you have not eaten anything extra. Infections and certain medications such as corticosteroids can also raise your readings temporarily.
Signs you should see a doctor
Unusual thirst, urinating a lot especially at night, unexplained weight loss, blurred vision, wounds that are slow to heal, or numbness in your feet — get tested early.
If you are taking blood sugar lowering medication, learn to recognise low blood sugar: shaky hands, sweating, dizziness, ravenous hunger. When that happens, take about 15 g of fast-absorbing sugar right away, such as half a glass of a soft drink or a few sugar tablets, rest for 15 minutes, then measure again.
