Still here. I combine low UPF with intermittent fasting (daily), which I don't track because it's a lifestyle for me rather than a diet of any kind. But I fast anywhere between 16-20 hours a day, and eat in a window of 4-8 hours.
Sounds miserable to some, but I like it and honestly can't imagine wanting anything other than black coffee and water until at least mid-afternoon.
When I'm eating, I just try to mostly eat real food. Not necessarily 'healthy' food - last night I had a big pile of home-made chips! I have the odd full-sugar Coke about once a fortnight, I have the odd shop-bought sandwich, eat the odd pack of decent quality ready-salted crisps. Have fish and chips from time to time, from the local chippy. Drink a glass of wine almost every night. Make myself shortbread at home if I want something sweet, or have a high quality yoghurt that doesn't contain any UPF, etc. I even eat a (reasonably decent quality) ready meal about once a week. And I've never been good at eating really healthy food - not a big vegetable fan, for example. So I'm definitely not depriving myself in the slightest.
I've done intermittent fasting for years, and it's done me a lot of good, but I was still a big UPF eater until a year or so ago. My weight was fine, but not ideal. I tended to have IBS-like symptoms fairly regularly. I felt rubbish when I ate UPF - it was shop-bought cakes, biscuits, crisps, chocolate that I always went for. But somehow couldn't stop myself eating it anyway.
Then I read the Chris van Tulleken book and it was a revelation. I honestly don't want to eat all of the UPF junk anymore. I lost weight, I felt better in myself, I no longer rush to the bathroom after eating or first thing in the morning with explosive diarrhoea. 🤣 I don't miss it at all. And despite not eating particularly 'cleanly' and not giving up wine, I hope that by cutting out most UPF and continuing my fasting lifestyle I am massively reducing my chances of Type 2 diabetes, obesity, cancer, heart disease, Alzheimer's etc. 🤞
