Boiled Egg (1 Large) and Americano Coffee (1 Medium Fast Food Order)

Keep the Americano plain: avoid sugar, syrups, flavored creamers, sweetened milk, and sweetened plant-based creamers.

Try a smaller Americano, half-caf, or decaf; caffeine can raise glucose for some people even without added sugar.

Drink the coffee after or alongside the boiled egg rather than on an empty stomach.

Add a small portion of avocado, almonds, walnuts, or chia seeds to make the meal more filling and potentially blunt the response.

Pair the egg with non-starchy vegetables such as spinach, cucumber, tomatoes, mushrooms, or peppers.

Test different coffee timing and caffeine amounts on separate days to identify the option that produces the lowest personal response.
