Boiled Egg (1 Medium) and Instant Coffee (made from Powdered) (1 Coffee Cup (6 Fl Oz))

Choose plain, unsweetened instant coffee and prepare it with water; avoid powdered coffee mixes with added sugar, maltodextrin, or sweetened creamer.

Keep the boiled egg, but test the egg and coffee separately on different days to identify whether the rise is linked to the coffee powder, caffeine, or another ingredient.

Have coffee after a balanced meal rather than on an empty stomach; pair it with low-carbohydrate options such as eggs, avocado, or nuts.

Use a smaller serving or a weaker coffee preparation, since caffeine can temporarily raise glucose for some people even without added carbohydrate.

Check the label for total carbohydrate per serving and measure the powder rather than using a heaped spoon.

Take a gentle 10–15 minute walk after eating or drinking, if appropriate for your health and mobility.
