Hi Kath, I’ve googled this and from what I can find is that if you don’t go lower than 20g carbs a day and keep WELL hydrated you should be ok. The carb number most people aim for on this diet is about 50g a day. There don’t seem to have been any clinical trials on this subject – just opinions.
The hydration level is very important in this regard so please make sure you drink your 2 to 3 litres of water a day.
I don’t know whether you have a history of kidney stones but if you do just keep yourself well hydrated.
Wishing you the best π
