Gold Standard Whey Protein (Optimum Nutrition) (1 Serving) and Coffee with Milk (1 Coffee Cup (6 Fl Oz))

Choose unsweetened coffee and avoid syrups, sugar, flavored creamers, and sweetened milk powders; these are often the main source of a rapid rise.

Use a smaller amount of milk or switch to an unsweetened, lower-carbohydrate option such as unsweetened almond milk; check labels for added sugars.

Use an unflavored whey isolate or a product with no added sugar, maltodextrin, or large amounts of rapidly absorbed carbohydrates.

Have the coffee-and-whey drink with a balanced meal rather than on an empty stomach; include protein, non-starchy vegetables, and a small portion of healthy fat such as almonds or chia seeds.

Reduce the whey serving size or split it into two smaller servings to see whether the response becomes smoother.

Take a 10–15 minute easy walk after the drink, if appropriate for you, and monitor your personal response to identify the milk and whey amount you tolerate best.
