Hi
@Suze A
Okay I haven't heard of Nuturacheck so can not comment on that.
If your levels are 19 that's actually quite high. You may want to try to reduce your carb intake but a reasonable amount and see what effect that has on your levels.
I am usually very strict keto and will be back on the wagon on the 28th at the latest. Even now when off the wagon my carb intake would be less than 50 grams a day. I personally find that usually the lower my carb intake the less cravings I have. However, I love carbs and tend to be an all or nothing person. Other people can have a higher level with no problem.
Good luck and welcome.
