what up zbr?! Glad to hear you're going to make the switch.
Your guidelines are good, but make sure not to be too rigid. You can have your cake and eat it too. The idea is real optimal health, not a narrow, rigid, limiting way of life. I don't feel limited by my way of eating and if you do, beyond a certain extent then perhaps it should be reevaluated. And i wouldn't try to go 100% raw right away, just transfer over at a rate that is comfortable to you. This should be a pleasurable experience mostly, not a burden.
Tips for getting down raw meat. Warm it up very slightly and gently to room or body temp. Most people aren't in to cold meat and I'm no exception. I much prefer meat at body temperature to fridge or room temp. A very QUICK searing is ok to start off with too, if done right, it will only cook the first millimeter of flesh or even less and the inside will be completely raw and unheated. best if left to room temp instead of cooking straight from the fridge. Eventually you will get to a point where searing is no longer necessary.
Yes like Ty said, anything cooked is going to form toxins, it's just how much you're willing to accept. I eat fried plantain, because I loooove fried plantain, but I do so knowing I'm not doing the best I can be for my physical health. Same would be for potatoes. But cooked food is one thing, processed food is a whole other. I would cut out processed foods to as great an extent as possible ASAP.
Steamed fish is going to lose it's enzyme and microbe value, and will form a limited amount of toxins, but is vastly better than dry heat like broiling or frying. Yes you could ramp it down until you hit raw, nothing wrong with that. I view 100% raw as a great ideal and I'm always striving towards that, but even after 3 years on this diet I'm still eating plenty of cooked. It is all about what you're willing to accept. Is it worth it to you to have that flourless chocolate tort, even though it's got sugar and other cooked ingredients in it? To me that would be a giant hell yes, once in a while, but then I will eat a bit of extra grass fed fat and/or some extra veggies to counteract it a bit and also I accept whatever the consequences are.
It's a personal journey and only you can decide what opportunity costs you'll accept. Buona fortuna!
