That's great! Congratulations. We (husband and I and a friend) lost a lot when we first went on the keto diet. It levelled off after a month though. The trick is working out how to combine it with your social life. It can be very restrictive and I definitely wouldn't recommend just dropping it every time you have a social event. For us, the best thig seems to be eating *before* you go out, and taking some keto snacks. Then just refuse all food offered. If someone forces food on you (I'm thinking Indian aunty- we have this problem all the time in Malaysia so I guess you do too), quietly slip it to someone else when she isn't looking, or to the dog. Or tell her you're not hungry but you'd love it later, and package it up to take "home", then drop it off to a homeless person on the way home.
It's great to see you under 100 and I hope you can keep it up until you reach your goal!
