the contents may be too early to become useful for girls here, but before i forget, i'd like to write down my experience.

the actual topic should be "weight control during pregnancy"

if you're pregnant, many people will encourage you to eat more. however, in fact, that's not ture.

during the first trimster (0-14 weeks), one only need less than 200 more cals per day than usual -- which is 1 small low fat yogurt (170 cal). if one eats like this, she will likely put on 3 or 4 pounds for the entire 14 weeks.

during the second and third trimster (15-40 weeks), one only need 300 more cals per day than usual -- which is 1 small low fat yogurt and 1 oil fried egg (100 cal). if one eats like this, she will likely put on 1 pound per week.

the total weight gain will be around 30 pounds while the suggested weight gain
is 25-35 pounds.
