Boiled Egg (1 Large) and Espresso Coffee (1 Espresso Cup (2 Fl Oz))

Have the espresso after a balanced meal rather than on an empty stomach; the egg can be part of that meal.

Try half-caf or decaf espresso, since caffeine can raise glucose in some people even without sugar.

Keep the coffee plain: avoid sugar, syrups, sweetened creamers, and flavored milk alternatives.

Pair the coffee with a small portion of almonds, walnuts, or chia seeds if you need a snack.

Take a 10–15 minute easy walk after eating and drinking the coffee.

Check your response on separate days with regular versus decaf espresso to identify whether caffeine is the main trigger.
