So, that is 20g carbs per serving. 3 servings a day = 60g (Assuming 3 servings is the recommended amount.)
I agree that some will, but most don't according to reports on this forum. From what I have read up to around 30g is the band, but some will be able to go above that. As with everything else, one size does not fit all. I cannot speak from experience because I have never felt the need to check my ketones and have no idea whether I am in or out, but I did lose all my weight on carbs ranging from about 100g at the start to around 60g by the time I reached my target weight, and my visceral fat measurement was 6. I then dropped to about 30g carbs, maintained my weight, and after 4 and a half years my visceral fat remains at 6. (very occasionally it has been 5). Sadly, I don't know what it was before diagnosis but I did have a large spare tyre!
