There's nothing too controversial about Peat. It just needs heavy adaptation for the individual and you need to eat PROPER MEALS. I cannot stress how much I started doing well on my diet when I began eating more actual meals instead of a fruit basket and tons of OJ. OJ is great - as the drink with your MEAL to blunt endotoxin (according to new research posted a while back). It's not something i'd drink in isolation, loaded up with salt so your body "treats it like solid food" (lol).
Also, get more starches - New York bagel for breakfast (with scrambled egg on top), seasoned couscous, white rice based meals (such as mild, low PUFA curry), potato + small amount of melted cheese for lunch, stews with mashed taters (a nice gelatin opportunity too with the gravy). Stop fearing wheat too, unless you really are intolerant. It's not this big bad wolf that if you avoid, will cure all ills (unless you are celiac). A moderate amount of it is okay.
I also echo the idea of lowering fat - not necessarily 'low fat', just as low as you feel comfortable with. Stop eating ice cream as a staple if you are doing this already as it's extremely fattening - look at Josh Rubin. Reserve it as a treat pudding a couple of times per week. I enjoy low fat cottage cheese (amazing protein source and with honey it's fantastic). Conservative butter usage is recommended ie. thinly spread over bagel. Semi-skimmed milk is superior to full fat (nutritionally) and is not as fattening.
With the lower fat, that creates some wiggle room to mess with coconut oil too (which I think people make the mistake of using on top of a high fat diet). Maybe a teaspoon in the milk before bed time, with honey and a bit of salt, will help you get to sleep better.
And on the subject of sleep, I feel it's underplayed in the Peatarian community. Ample, WELL TIMED sleep (10-11pm until 7am) is utterly essential for well-being. Peat has said a poor nights sleep can take days to recover from, physiologically. Yet, no one talks about this in the community. We spend too much time mentally masturbating over the stress of darkness and melatonin, bathing under red lamps for hours a day, when the answer is just eat a good supper to equip you for the night and get to bed on time.
That's not to say supplements, drugs and weird shit like red lamps don't have their place. I use the occasional pregnenelone when I notice my skin looking less lustrous. Also don't be afraid to try some stuff that isn't necessarily Peat sanctioned but has a lot of safety evidence for on Pubmed. I got into all this dieting to beat baldness - it didn't work, but ultimately the finasteride seems to be helping at last. I also really like Haidut on the Ray Peat forum's posts about specific vitamins, and I used his knowledge to make a cheap aromatase inhibitor (Estroban) out A, D, E and K dissolved in milk before bed.
Finally, I feel that exercise is very very important. I hit the gym several times a week now and am in much better shape and have way more strength than a year ago. It's not a problem as long as you exercise intelligently - mild cycling and walking for the cardio, and weightlifting for strength. Take plenty of breaks, sugary drink on hand. Functional Performance Systems, and some of Cliff's recommendations for post workout snacking have been very beneficial for speeding up recovery time and not killing the thyroid while getting fit.
PS: Eating strictly is a stress in itself. I'm not going to say I cured all my problems by going YOLO and eating pizza 24/7, but it is very important to cheat. Say, fast food or a really anti-Peat meal a couple of times a week. I eat McDonald's, for the new weekly burger, and enjoy a pizza now and again. Also don't get aspie about labeling - it's fine if the odd food has carageneen or gums in it. Peat also often mentions certain things "can be allergenic", yet the community glosses over the first two words..
