The hubby who is pretty strictly Keto, considered "ketovore", and he is usually around 25 carbs as an active male in maintenance. He does a cheat day maybe every 2 months, that's usually an asian buffet and he still makes smart choices but he allows himself carbs.
My low carb diabetes control guidelines are generally considered on the low side, my goal is/was 100 per day, even my nutritionist said I could go up a bit from that. Most of my eating was not so much about weight but about blood sugar control, but when I'm eating well and losing weight, I'm down more to around 60-75 carbs. I am just not willing to give up half an apple or banana a day which is pretty much all it would take.
Hubby is very happy eating mostly meat, I'm more plant/grain based and always have been. I'd rather sit down to a big bowl of salad -- which can be keto too, but I also am having dental issues and don't have much to chew with either meat or vegetables.
