Pay attention to the heat demand.
There is no need to increase calories in the first trimester, and 300 calories/day must be increased in the second and third trimesters according to the calories required before pregnancy. Weight loss may increase ketone bodies in mothers.
Pay attention to the distribution of meals.
In order to keep the blood sugar level stable and avoid ketonemia, the distribution of diet is very important. Because eating a large amount of food at a time will lead to a rapid increase in blood sugar, and mother's fasting time is too long, which is easy to produce ketone bodies, so it is recommended to eat a small amount of food. You can eat 5-6 times a day, and it is best to eat some food before going to bed, so as to avoid the long interval between breakfast and night, and pregnant women will not wake up in the middle of the night because of hunger.
Take the right sugar
Sugar intake is to provide calories, maintain normal metabolism and avoid ketone bodies. Don't eat too much sugary food after meals, eat some rice foods in moderation, and eat less honey, sucrose, rock sugar and other foods.
