Calculate the calories required by expectant mothers every day
There is a formula for calculating the daily calories required by ordinary women, and expectant mothers can refer to it. Namely: daily calorie requirement =[65.5+9.6× body weight (kg)+1.9× height (cm) -4.7× age ]× activity. Among them, the activity value is between 1. 1~ 1.3, when the activity is high, it can be multiplied by 1.3, and when the activity is low, it can be multiplied by1.
You need to increase calories properly after pregnancy. The Nutrition Society of China advises women to add 200 calories a day in the second and third trimesters. 200 calories is equivalent to more than half a bowl of rice, or 1 egg with 200ml milk or a piece of bread with L cup of yogurt, or a piece of bread with 1 apple of medium size. Expectant mothers can count and eat.
I am thin and gain weight slowly after pregnancy. I gained 0.5 kg after 3 months of pregnancy. Is it normal?
The weight gain is not ideal, so we should pay attention to the measurement error before we can see the baby's development. If the development is normal, don't worry. If the development is slow, you should be treated. In addition, she is thin before pregnancy, and her weight gain is slow after pregnancy. She may have gastrointestinal diseases or other chronic wasting diseases, which need examination and treatment.
Finally, I hope expectant mothers will remember that no matter whether you are overweight or not, you should never control your weight by dieting or gain weight by eating sweets, which is not good for your mother and baby.
