Hi and welcome.
I recommend you go with what we have on the sticky thread at the top of this forum,
Atkins Induction Acceptable Food List. I've technically never followed Atkins by the book - I started out with Protein Power (by the Drs Eades) - but I find the induction rules really easy to remember off by heart, and I like his use of the word "liberally". It doesn't mean it's a freebie - for a lot of us, water is the only true freebie - but it means go ahead and have as much as you feel you need. Just observe the limits on the other foods - cheese, artificial sweeteners, etc.
I'd also consider green veggies a freebie, although there's technically a limit on them. No one ever got fat because they had 1/2 cup too much of lettuce.
I know if I was starting from scratch, I'd have certain foods considered freebies although they're not:
- coffee/cream/splenda (because it kills my appetite and I really don't drink that much)
- salty broth (helps prevent induction blahs)
- pork rinds (read labels! Here in Canada, there's only one brand available and the only ingredients are pork skin, lard and salt.)
- Diet Pepsi (sue me. It's my one vice.)
- Canned parmesan cheese on a lot of foods over other cheeses, because the saltiness prevents me from overindulging
Best of luck to both of you. Feel free to ask about suggestions based on your lifestyle: do either of you work long hours and/or you don't like cooking? Do you have a shoestring budget? Any other preferences? Guaranteed we can help.
