Ahhhh. Those dang hormones. It's like a guy with gyno x 100
OP. stop taking food from the baby. LOL.
I don't think ripping food from a pregnant woman is good idea, EVER. And this woman you love so much is no longer the same woman when she's preggies.
Read your responses and you clearly want her to not have to go thru the struggle of weight loss and it also seems you can't do anything right. So you can just let it happen and after the baby and after the hormones calm down post delivery, try to reason with a non pregnant wife. My gf say breast feeding with help shed weight.
Maybe make a deal that she try to not gain more then x pounds from now to end of pregnancy or better yet have the doctor highlight that this extra weight is not baby and she will get to keep it.
My gf obgyn said if she started gaining size in the thighs, she would get to take that weight home with her and not in the baby carriage.

. Funny obgyn. Your obgyn should be concerned about excessive weight gain. It's not healthy for wife and therefore not healthy for the baby.
Focus convo on health of baby not how fat wife will be. It's not healthy for the baby. Our baby needs highly dense nutritional food. Our little baby blah blah blah. And don't be a nag.
And geez. Why not eat the dang yolk for a few months. It is really worth that battle? Just sayin.
