I lost about 25 kilo's (55 pounds), probably more, because I'm not quite sure what my starting weight was: I quit weighing myself at 102 kilo's, but I know I got bigger than that. With the bulk of that gone, the fat marbling my liver went away too. Liver function was back to normal in 3 to 6 months. My HbA1c is still in the normal range, and I have tried a few diets, going from low carb to keto to carnivore for a bit (which is zero carb), but I've settled back into keto again, maintaining about 20 grams of carbs a day or less. It's quite doable, and I don't think I'll venture into other diets from here on in, unless medically required to do so. I did regain a bit of weight when peri-menopause kicked in, but, well... I'm comfortable as I am now. It's still quite a few dress sizes down from where I started, my blood sugars are fine, no diabetic complications, my energy levels are nowhere near what they were back then... I'm calling it good. I still have my sweaters from that time, and while they were very snug then, they're quite copmfortably oversized now. I'll attach two pictures, I think you can tell by my face that there was some weight lost in the one where my hair's grey.
Basically I eat coconut yoghurt (with Purition for flavour and fibre) practically daily, and have taken to drinking kombucha for gut health, (Was on a lot of antibiotics lately for my jaw). Other than that it's eggs, veg, meat/poultry/fish, the usual low carb fare. When we're out I usually order eggs, a salad or something with the spuds replaced by veg, and bread or toast left off entirely. Sometimes I'll add a side of baked mushrooms or something if it's not filling enough without the carbs in. A kitchen is usually happy to accommodate if it's just leaving something off... Better than throwing a perfectly good part of a dish out. (And I'm a notoriously good tipper). I'll have a cappucchino with soy or oat milk when out and about too, which is about as carby as I'll have a drink now, but I get away with those. Milk is a problem, it makes my rheumatism flare, so I'll treat myself if soy/oat is available.
You eventually slide into a routine that works for you. Takes a little getting used to, but it can and does work. And, again, my story is just one of many.
