Before you try anything fancy, see what happens with a couple of weeks of raw paleo diet. I prefer nothing fancy - I get a hunk of grassfed beef (3 to 5 pounds of "roast" from the round because it is relatively cheap, my butcher leaves the back fat untrimmed). I also eat raw fish and seafood.
Dr. Gundry is a variation on Atkins. I am familiar with Atkins and Taubes, and I use their advice to a certain extent, but I'm all raw. I eat very low carb, much raw animal fat, and moderate protein. As far as your specific question about nuts on another thread, you can probably get the best answer for yourself through trial and error. If you ask the forum, each person will give advice on what works for them, and that may not be your experience at all. I try to make one change at a time so I can keep track of what my reaction is.
After a few months of RPD, my dermatitis was gone - it was mostly in my eyebrows, back and ears. If you are adventurous and not too modest, you can try getting a scrub at a Korean spa (jimchilbang). Google it and see if it is for you. A scrub is a waste of time if you are not eating right, but it is a wonderful experience if you are eating right to create good skin.
