I think your goals are admirable. So many get caught up in how much they lose, how fast or slow they lose, how long it takes, etc. as they’re losing. Of course when we’ve lost our weight we all feel pretty darn happy about what we have achieved (& deservedly so).
How you eat after you’ve stabilised is really up to you & how you want to live your life. If eating carbs fits in better with your lifestyle & your family then eat carbs. Just maybe choose better carbs - complex, whole & multi grains, low processed versions, smaller portions, or less often. You’ll work out what & how much of certain foods or food groups you need to eat, can eat, can eat occasionally, or those you may be better off avoiding. It’s your choice. Of course we can’t go back to how we used to eat - that’s just asking for trouble 🙂. Accompanied with this may be that your weight settles a little higher than at your lowest as you work out your caloric needs (what your body needs to function effectively to maintain your weight & activity level), eating style & lifestyle preferences and that’s okay.
For me deciding not to call how I ate after I stabilised a ‘diet’ was a positive mental move. I’m not on a diet this is just how & what I eat. Diet had such negative connotations & memories for me: restrictions, being limited, missing out, etc. & failure.
Personally, I cut out a lot of sugar & generally avoid artificial sweeteners & sugar substitutes whenever I can so I don’t eat cakes, biscuits, desserts etc. except a couple of times a year like Christmas. Don’t miss it. Don’t feel I’m missing out or being restricted & my friends & family accept it, no fussing or pushing me to eat. For example my niece was serving out cake for her 13th birthday earlier this year. When she got to me she asked what I’d like and added we have strawberries too. (I had strawberries.) It didn’t happen overnight but slowly it became just me.
All the best.
