Oat meal (1 piece)

Choose steel-cut or old-fashioned rolled oats instead of instant or heavily processed oatmeal, and keep the portion modest.

Pair oatmeal with protein and fat, such as plain Greek yogurt, eggs, chia seeds, walnuts, or almond butter, rather than eating it alone.

Add fiber-rich toppings such as berries, chia seeds, ground flaxseed, or cinnamon; avoid honey, maple syrup, brown sugar, and sweetened dried fruit.

Cook oats less until they are not overly soft, and avoid blending them into smoothies, which can make them digest faster.

Have a short walk or other light activity for 10–20 minutes after eating to help reduce the post-meal rise.

If spikes continue, try a smaller serving and monitor your response; consider discussing individualized targets with a clinician or registered dietitian.
