Before lunch (1 piece)

Keep any pre-lunch snack small and pair protein, fiber, and fat—for example, plain Greek yogurt with berries or a small handful of nuts—to reduce a sharp rise followed by a drop.

Avoid sugary drinks, sweets, refined pastries, and large portions of rapidly absorbed carbohydrates before lunch.

Try moving the snack closer to lunch or skipping it if you are not hungry, while keeping meal timing consistent from day to day.

Choose a balanced lunch with protein, non-starchy vegetables, and a modest portion of high-fiber carbohydrates such as lentils or chickpeas.

Track the timing, contents, and portion size of your pre-lunch food alongside your glucose readings to identify your personal trigger.

If you have symptoms of low glucose, recurrent drops, or take glucose-lowering medication, discuss the pattern promptly with your clinician and follow your prescribed low-glucose action plan.
