I am a first time mom so I am not familiar with this.... can you share if you have experienced the same?
I get REALLY hungry and then when I go to eat, a couple of bites completely fills me up, to the point of stuffed. I am eating a lot of protein and veggies (trying to stay away from all the carbs I ate in the first trimester) so I know that has something to do with it. However, I have eaten low carb in the past and had no problem finishing my plate. The hunger and the sudden fullness just started this week (I am 17 weeks tomorrow), so maybe it is just the baby pushing my stomach up and making me feel full faster?
