I think the "easiest" way to deal with it is to make sure you have eaten before you cook the tempting foods for him. That way at least you are full and should then be less tempted to sample and taste.

My hubby tends to eat all the bad food that I'm not allowed (ie junk food, rice, pasta etc). If we're sitting down to watch a movie or something I munch on sunflower seeds when he's eating junk food. That way, if I'm eating something, it's easier to avoid the junk food temptation.

When we're sitting down to eat dinner, I just make sure there's a lot of the things I'm allowed and eat to my heart's content.

It's hard to resist the temptation when it's in your face, but it does get easier to do and you will feel a lot better about yourself when you do resist!

Good luck!!
