Dietary control is extremely important for gestational diabetes. Eating too little may lead to poor fetal development, while eating too much may cause blood sugar levels to be difficult to control, leading to macrosomia or even adverse pregnancy outcomes. Therefore, paying close attention to diet is indeed necessary. As for how much to eat, it can be calculated based on the total calories needed throughout the day, with breakfast accounting for about one-third of the total calories. Specifically for breakfast, it should consist of carbohydrates and protein, a moderate amount of fats, and certain vitamins. For example, for a user weighing 50 or 60 kilograms, breakfast could include 250 milliliters of pure milk, an egg, along with some whole grain bread or steamed buns, approximately 100 grams, and some vegetables. You could have cucumber salad or some kelp strips, which are low in glycemic index and can help fill the stomach. Additionally, between meals, such as between breakfast and lunch, it is appropriate to have two walnut kernels to keep blood sugar from spiking while achieving nutritional balance.
