Extra Virgin Olive Oil (1 Tablespoon)

Check whether the rise is from foods eaten with the olive oil rather than the oil itself, since extra virgin olive oil contains virtually no carbohydrate.

Use a smaller measured serving, such as 1–2 teaspoons, and avoid adding it to refined breads, potatoes, sweet sauces, or other rapidly absorbed carbohydrate foods.

Pair olive oil with non-starchy vegetables, such as leafy greens, broccoli, zucchini, peppers, or mushrooms.

Include a protein source with the meal, such as eggs, tofu, fish, chicken, or plain Greek yogurt, to make the meal more balanced.

Choose slower-digesting carbohydrate portions when needed, such as lentils, chickpeas, beans, or steel-cut oats, rather than refined grains.

Compare readings on different days under similar conditions and consider the timing of your measurement; a small change may reflect normal meter or sensor variation.
