Thanks for the welcome, Dylan and Robert!
Great to have you here and we're here to help answer those questions for you and address them with success.
One question I have is why avoid high carbs? If you're referring to avoiding processed carbohydrate foods, I understand that, but a high carbohydrate diet from whole foods is the healthiest kind of diet there is. What we want is a diet high fruits, vegetables, nuts, grains, seeds, beans and other legumes, etc. I know carbohydrates got a bad name from breads, refined flours and sugars, chips, pasta, etc. but science says carbohydrates from real foods are the best things we could possibly eat.
I pretty much avoid processed carbs now, so there's no need to make a change on that front. But I seem to get sluggish when my diet skews too heavily toward grains and legumes. I already eat boat-loads of veggies and a reasonable amount of fruit. I'm checking out the Vegaone protein I've seen mentioned here and hope to replace my whey with it. Any suggestions for a tasty substitute for Greek yogurt?
For your family, I would suggest adding more and more whole plant foods into the diet. The more plant foods there are, the less room for other things. Find themes they like, ethnic foods, or certain styles of foods be it rice and vegetable dishes, various seasonal fruits, heavy foods like beans or lentil stews, etc. Finding the foods they already like, adding more in that category of food from a variety of sources is one way to keep everyone enjoying plant-based whole foods.
Thanks for these suggestions. I already do a lot of plant-based cooking since we're all (except one) vegetarian. It's eliminating dairy -- especially cheese and cream sauces -- that may be tricky. I have a copy of Joanne Stepaniak's The Uncheese Cookbook and I need to experiment with it more.
