I hesitate to write this because I don't want to ruin the intent of your thread, but I also feel strongly that suggestions for a slow switch to RPD can mask its immense benefits. A person new to RPD should know the cost of going slowly.
If I had eased into raw, I would have never known how beneficial it was. I would have continued hurting and eventually walked away for lack of improvement. Anybody considering half measures should read this statement as a disclaimer.
Maybe that will not necessarily be the case if easing into the diet is done right.
Because I am breastfeeding, I could have never went cold turkey. On top of that I was dealing with hypoglycemia. I HAD to be able to function and take care of my baby during the transition phase.
I eased into the diet by cutting out foods first. In pregnancy I cut out sugar, but not much else because I relied on bread for "energy"...at least my body thought so.
Anyhow, I cut out grains first (except rice), just a few weeks later I cut out potato and rice too, then dairy. By going step by step I could watch how my body was reacting to it.
Immediate benefits were not being so hazy anymore, my skin improved, no more back pain, even on just less of the SAD foods.
I think I transitioned within about 2 months.
That said, I can see how some would just get lost and procrastinate transitioning fully. But if you have a plan, I think going a bit slower can work.
Once I was at least fully Paleo, partly cooked still, I started noticing even more benefits. The longer I was on the diet, the more severe/ obvious my reactions were when I cheated and ate something I shouldn't.
I eased into raw meat by seasoning with onions, garlic, olive oil, herbs, wasabi, and very small amounts of salt and pepper. I still season my meats, but less since I am not as grossed out anymore.
I try to make raw meals appealing and like little recipes.
I tried going cold turkey on raw meat and just eating it, but that is what actually almost discouraged me. At least my body was just utterly disgusted.
