Brand new to all of this and have a few questions. I am on day 2 and have been using the guidelines but not necessarily the recipes. I have never been much of a veggie or fruit eater so this is all very new for me. For snacks, I have been using pistachios and almonds, I am not used to eating nuts as most diets consider the calories not worth it, can these sabotage the good I am doing by losing the white flour/rice and moving to whole grain/brown rice? Also, it is normal to have a headache the first few days? Finally, with work I have to eat out a lot, any tips for restaurant eating, particularly salad dressing. Thanks
