Welcome Ellie. I am glad you are loving your new way of eating and the results it is giving you.
As for helping your man get on board, might I suggest being sneaky about it. My husband seems to me to be completely uninterested in learning about nutrition for the good of his health, despite some glaringly poor blood test results and the fact that last year's clothes don't fit.
Yet, he is also contented enough to eat what I put in front of him (and why wouldn't anyone when it is so delicious, it's not like he's going to go raid the pantry for something else, especially when it's not there anyway,lol).
I have noticed improvements such as less snoring, better digestion, and I think his skin looks healthier, even though I would say he's only about 50% primal. I would love for him to get on board fully but meanwhile I just keep cooking a primal dinner, packing leftovers for his lunch, and "accidentally" running out of bread. I have changed to buying fullfat milk, mix his too-sweet yoghurt with fullfat greek yoghurt and add nuts and coconut to his muesli while he is not watching. I try to fill him up on good primal food so that he feels no need to search for anything else, but it's difficult at times. I'm trying to think of more things I can do, short of asking him not to eat sugar, bread, coke etc. so I will look to see what other replies you get.
I am more than happy to do the cooking in order to see him eating well.
