Love this analogyIt's obvious from the various accounts on here that we are not built the same way. Some of us on low carb or keto lose body fat and reduce BG: others do one but not the other. It is not as simple as it is sometimes suggested. For me, my BG was back in normal range in four months at 20g/day, and over the next three years I lost around 90lbs. BG first, substantial weight loss some long way behind. So the "lose 10% of body weight first" requirement doesn't work with me.
It's possible perhaps that we may have slightly different conditions, so we respond differently to low carb/keto depending on what part of the very complex body system is broken or impaired. We may all have the same raised blood glucose symptom, but it's possible that it doesn't always have the same exact cause - if your car's mileage suddenly goes down it might not have the same cause as my poor mileage: you've got ten bags of cement in the boot: I'm driving everywhere in second gear: Bob down the road hasn't had his car serviced for five years.

If you get a BG meter or a CGM then you can also check which foods are the worst for your numbers and which are OK. People seem to react differently to each different carb and even some proteins. So this might help you make some tweaks which may be easier to maintain longer term.
Wearing the CGM was also useful to me as it helped me understand how much pain and inflammation affected my blood glucose level, which is another variable.
