After doing the holistic thing for years, I can confidently say now that I no longer get acne. If there's anyone out there doubting that there's an "acne-free future," there is. The good news is that it's very possible to reverse your health to the point where your skin is actually IMPROVING, the bad news is that it takes a while to get back there and requires you probably do some "unorthodox" things. As you can see, I've been a member of this board for years and only in the last few years have things finally "clicked together."
My diet currently:
Moderate amount of starches, to restore muscular glucose over liver glucose. Usually in the form of russet or sweet potatoes. Sometimes I get organic potatoes when I can afford them.
Sometimes oatmeal for breakfast, soaked for a day or two.
Drink a cup or two of raw milk a day, hard cheeses, greek yogurt. I've personally never noticed any change in my acne from dairy, probably since my ancestry is from Northern and Eastern Europe, except cheap grocery store heavy cream (which has many ingredients used to make it thicker.)
Fruit, very little. I like lemons, limes and coconuts. Trader Joe's has really inexpensive lemons (cheaper than the grocery store for some reason.)
A decent amount of coconut/coconut-derived products, mostly in the form of coconut milk. But also sometimes shredded coconut, coconut water, and coconut oil (which I buy by the gallon.)
Kerrygold Butter, suet and tallow are all fats I use to cook my food.
Bone broth and liver every few weeks.
Large amount of meat. Lots of uncured organic bacon, shellfish, and beef/pork. Usually free-range/pastured. Very rarely eat chicken. Eat most of my meat medium-rare/semi-raw.
Soups regularly, often with "starchier" veggies like beets, carrots, turnips, parsnips, etc.
Salads rarely, green smoothies more often than salads.
Dark chocolate mainly
Black coffee, once in a while, for the taste. Depending on your T1/T2 immunity dominance, coffee can be really beneficial. I think it's beneficial primarily for T2 types and T1 people are more likely to feel jittery or stresses (adrenals) from coffee and caffeine products.
Very very very small amounts if I choose to. In the past, I cut out wheat completely and now believe that periodic wheat/gluten exposure is necessary to avoid hyper-reactions from when you do consume it. However, if you're still breaking out, I wouldn't even bother thinking about this and instead avoid wheat entirely. That's what I did.
Also I can gladly say I've never had to go through a coffee enema/vegetarianism/veganism to get clear skin.
