Hello! in 2011-2012, I lost 100 pounds on lazy Atkins. In 2013, I gained half of it back. I've stayed within 175-185 since, probably because I have to walk at least six blocks to get to a grocery store. For the last year, I've been pretty much a junk food vegetarian.

In 2016, I was diagnosed with Parkinson's Disease. This week, I found a study from 2018 that put 47 Parkinson's patients on either a low-fat or a keto diet for eight weeks. Both groups saw improvements, but the keto group had more improvement of non-motor as well as motor symptoms.

Low‐fat versus ketogenic diet in Parkinson's disease: A pilot randomized controlled trial is not behind a paywall. Near the bottom of the page, open the tab labeled "Supporting Information" and you can download both the "Low Fat Standard Diet Plan" and the "Ketogenic Standard Diet Plan", which include shopping lists and recipes for eight weeks of meals. From the paper, "The ketogenic plan provided 1,750 kcal per day composed of 152 g of fat (67 g saturated), 75 g of protein, 16 g net carbohydrate, and 11 g of fiber".

I've reached a point where I have unpredictable "off" time, ie, when my medication doesn't work very well. I fell and broke my knee cap in March, and I broke a couple of ribs two weeks ago. I'm interested in doing it, but it would mean eating meat again, which I stopped for ethical reasons, and I'd spend a lot more time fiddling around with food. When I did LC before, I was a very plain cook. Scrambled eggs in butter, a couple of plain burgers and a sliced cucumber in vinegar and olive oil, a couple of string cheeses and slim jims on the road.

I haven't looked closely at the low fat option ("1,750 kcal per day composed of 42 g of fat (10 g saturated), 75 g of protein, 246 g net carbohydrate, and 33 g of fiber") because I tried Pritikin, Ornish, etc back in the 90's, and when I could stay on the diet for a week or two, I'd start getting cold, cranky, and sleepy during the day.

Has anyone else here used LC/keto therapeutically against Parkinsons, Alzheimer's, ALS, etc? What have your experiences been?
