Yes I lived on them during my first trimester due to severe morning sickness I think that contributed to my rapid weight gain

@wandal24,

yup or carnation shakes. we give them to a few of my clients at work to help gain weight or keep their weight level if they aren't eating

You can eat healthy, making sure you're eating lots of protein and do strength training with weights. Google "how to gain weight the healthy way". Hope this helps!
