I'm hoping this diet dies off. The moniker is really really stupid and misleading.
Either way, I still advocate count calories and macros. I think restricting whole types of foods is harder to maintain than an accurate food log. You've got 3 young daughters, some days, that donut is going to look more tempting than usual. But nope, can't have any of that, whatever group the donut falls into that you can't eat anymore. No more of that, at all, ever.
Yeah you can, just make sure you count it correctly. It's going to hit your calories and carbs pretty hard, just make sure to compensate later that day, or the week overall at worst. Though, I usually only try to carryover calorie surpluses/deficits day to day throughout the week, not macros. Going to gym regularly makes those extra snacks really easy to manage. There are some days, especially in the summer when I mow the lawn, where I feel I have to eat too much.
Telling someone they can't eat something can make them miserable, psychologically(notice how you've already said dairy can't be restricted?). It's a childish way of handling things. And if it weren't such a common thing in our culture, I think more people would be offended when told "don't eat this", instead of "watch more accurately what you eat". I know it's grown out of the fact that most adults essentially eat like children, but I think we should treat ourselves and our loved ones with more respect.
