Yeah, I feel pretty good. I feel much better than when I am eating a wider variety of food. I find with bread I go through many highs and lows. I do miss fruit. Maybe I could reincorporate it. I just don’t want to have too much sugar. Avoiding pre-diabetics and diabetics is very important to me.
I avoided sugar, flour, and fruit for years but never bothered being low carb. The world of carbs is massive, and there are very few conditions that would warrant avoiding all of them.
I think your best bet would be to experiment with various forms of healthy diet to see what works best for you. If you feel just as good incorporating legumes, whole grains, fruit, etc then no need to exclude them.
Do it systematically. Add things one by one and log your symptoms, perhaps in a symptom app. That can help you figure out your optimal diet.
ETA: for the record, my MD recommended I switch to intermittent fasting. I'm quite sensitive to pretty much all food thanks to a condition called MCAS, so eating just once a day gives my body a break from the constant assault of food. Now I can eat basically anything, because my body only has to digest once.
I'm not saying this is for you, but thought I would share as someone who has had years and years of fine tuning how I eat to feel my best.
