Wow! Liz- how sweet of your boyfriend!!
My husband is totally supportive too. sometimes a little TOO supportive. His always on my case about what I'm eating- and he likes to question the guidelines of WW. The other day I went to the gym and he offered to make dinner so when I got home we could eat. He made fish- but it was REALLY salty. I tried to eat it - but it was just horrible! I thought my blood pressure was going to go up!! LOL So I axed it. His presentation was nice though. It looked pretty on the plate.
To answer your question- I believe a serving is 4 oz- which is roughly half a chicken breast. I know- 2 bites! I will usually eat a whole chicken breast. I don't do the 4 oz thing. I'd feel deprived.
