I've gone from keto to low carb. My motivation was blood sugar though rather than weight which maybe gives a different level of motivation.
I'm currently still underweight by about half a stone. I couldn't stop losing as I had gone off most keto friendly food so wasn't eating enough. Now I have some carbs with every meal but team it with fat to slow the absorbtion, I just watch my portions of carbs and try to stay at around 30g or less per meal and I've been told to ignore the carbs in fruit and veg but I still struggle with that.
My blood sugars initially went up but sticking to low carb and they have dropped again with no further dietary changes.
So, I tend to eat paleo granola with whole milk for breakfast or occasionally I'll have a small bowl of porridge with some berries. For lunch I'll either have a small baked potato with plenty butter and prawn cocktail/tuna mayo/cheese etc or a couple of bits of wholemeal sourdough with butter and pate or cream cheese and a bit of salad.
For main meals I might have a little bit of brown rice or 30g wholewheat pasta or even a few chips if that takes my fancy. I usually also have some full fat Greek yoghurt with berries after dinner.
Snacks might be half a green apple with peanut butter or some nuts or a couple squares of 90% dark chocolate.
I find this completely sustainable for me but I still cannot put weight on. I add butter into everything and will have diet whey shakes (low sugar) made with whole milk and sometimes cream.
I think low carb will be good to maintain weight, but it just takes a bit of effort and restraint.
Well done for losing what you have, you can definitely do this.
For me, as I'd become quite obsessed, just not worrying whether the stock cube or tomato puree had 0.5g more carbs than the other brand helped me to relax and not get so stressed about it.
I was eating virtually no carbs at one point, nowhere near 20g.
Ive even recently had the occasional few crisps and I had roasties at Christmas without panicking. I just try to keep at 90ish grams a day but if I am out for a meal and don't know what's in a sauce then I don't worry about it as an occasional thing.
