While you are pregnant, you will need additional nutrients to keep you and your baby healthy. But, that does not mean you need to eat twice as much. You should only eat an extra 300 calories per day. A baked potato has 120 calories. So getting these extra 300 calories doesn’t take a lot of food.
Make sure not to restrict your diet during pregnancy either. If you do, your unborn baby might not get the right amounts of protein, vitamins, and minerals. Low-calorie diets can break down a pregnant woman’s stored fat. This can lead to the production of substances called ketones. Ketones can be found in the mother’s blood and urine and are a sign of starvation, and can be harmful to your unborn child.
