Mr. & Mrs. Lim (PooiWei)

Dear Doc,

Thanks alot for this informative site.

PW has since increased 13.5kg from 0-8th months. You've advised her on slowing down the weight gain but due to her huge appetite for food, if she were to cut down on the food intake, will it have any implication to the actual baby's weight? We could try to start eating less and cutting down on snacks. Our only concern would be to deliver an underweight baby.
Appreciate the reply.

Grossly, food can be divided into 3 categories:
1) Carbohydrate : Rice, noodle, white bread, sugar etc
2) Protein : Meat related diet
3) Fibers : Fruit and veges.

During pregnancy, due to reduced in physical activity, it is not necessary for the pregnant mother to increase the calories intake from carbohydrate.

However, protein and fibres related food is not restricted. The baby need more protein and minerals ( calcium ) to build and growth. High fibre diet is important to assist the bowel motion and is a form of vitamin supplement for the mother.

In conclusion, PW needs to control the carbohydrate related diet without reducing the protein and fiber intake in order to control her weight gain, without sacrificing the nutrition for the baby.
