Hi OP, came across your post whilst scrolling. So impressed by your progress and that you are just keeping going.
I'm a fair bit older than you and have spent most of my life putting on a stone/losing a stone. After a recent health scare I was prompted to take a look at my eating and realised I'd become very lazy - grabbing a sandwich and a cake from Starbucks for lunch every day; eating butter and jam on toast in the evenings; an occasional banana - that sort of thing.
It didn't seem that bad compared with how other people seemed to eat - I've never eaten chips and burgers or drank masses of alcohol - and I'd never been significantly overweight so thought I was fine. I clearly wasn't and my body started to rebel. Have been checked out and I'm okay now but it was a massive wake up call.
I'm now eating mostly unprocessed food and helping my gut health with masses of different vegetables. I'm so smug about the contents of my fridge 😀 I have just a small quantity of each of veg with herbs and spices and some unprocessed grain and add butter as I need it to taste good. Probably about a dozen or so different plants with my main meal. Also lots of nuts and seeds and occasional fish. Tried having dark chocolate but that gave me a headache.
I'm convinced that a healthy gut is the way forward healthwise and weightwise. Lots of info on YouTube from Prof Tim Spector and many others. Seems Prof Spector, as a young hospital doctor, had a takeaway sandwich, crisps and a bottle of orange juice for his lunch each day for 10 years believing it to be healthy.
What's come as a surprise to me is my reaction now to the foods I used to regularly eat - a takeaway prawn mayo sandwich; cake; toast; very occasional alcohol - all things that I'd have had previously knowing they weren't super healthy but feeling they were okay.
Now after eating almost exclusively unprocessed food for a few months I regard my presumably improving gut bacteria as precious and have no desire to sabotage them by eating as I used to, especially regarding unrefined sugar which promotes the bad bacteria, and am slightly repulsed at the idea of eating as I used to.
Life is precious and I need to help my body to do it's job. Wish I'd realised this 40 years ago but now I know, this is really so easy.
Sorry, that went on a bit. OP keep going and well done on your progress so far and for providing inspiration to others.
