Boiled Egg (1 Large) and Black Tea (1 Teacup (6 Fl Oz))

Drink the black tea plain: avoid sugar, honey, syrups, sweetened creamers, flavored milk, and sweetened plant milks.

Have the egg with a small portion of non-starchy vegetables such as spinach, cucumber, tomatoes, mushrooms, or broccoli rather than bread, biscuits, or pastries.

Add a fiber-rich side such as chickpeas, lentils, or beans in a modest portion to slow the overall glucose response.

Try having the tea after or alongside the meal instead of on an empty stomach; caffeine can raise glucose for some people.

Check whether the response changes with decaffeinated black tea or a weaker brew, since caffeine sensitivity varies.

Repeat the meal on a different day while keeping sleep, exercise, stress, and meal timing similar to confirm whether the rise is reproducible.
