Hi, I was wondering if anyone knows how much you are supposed to eat in the first trimester?? I have been previously dieting and eating an average of 1500/1600 per day, and was exercising 4-5 times a week. I am using MyFitnessPal which is brilliant for keeing track of calories etc. But now I am 5 weeks pregnant and am wondering if this amount of calories is still ok? Obviously now I am not trying to lose weight, but I want to maintain my weight. I am planning on continuing to exercise throughout pregnancy, my husband bought me a spinning bike for Christmas so I am going to be using that about 4 times a week for 30-45 mins at a time, keeping the workout moderate (not pushing too hard!!) Any advice would be sooooo appreciated!!! Thanks!!
