A. Oatmeal is prepared from oats, a good fibre, protein, and micronutrient source. However, oatmeal generally contains low amounts of carbs in them. For example, a 100g of oatmeal has 12g of carbs. Therefore, one can consider it a low-carb diet, but one must take care of its portion size. Too much consumption of oats may exceed the limit if you are on a low-carb diet.
