Does anyone have the same problem as me? I use fitness pal and nearly every day my sugar levels exceed their recommended 24g. I have always eaten a lot of fruit because it is supposed to be healthy and it is low in calories. When I was on a weight watchers diet I would eat a bow of fruit for lunch. I have cut out the pineapples and grapes as they seem to be very high and virtually do not eat yoghurts either now but still manage to exceed the limit. Even on a fast day I can be over so it leaves me not sure what to eat. I have read somewhere that some people recommend only 2 portions of fruit and 3 vegetable so maybe that s the way forward for me. Would be very interested on what other people think. I am losing weight on the 5:2 and find it is better for me than any other weight loss programme but one of my reasons for doing it was to reduce my blood sugar levels from 6.1. I was diagnosed with impaired fasting glycaemia a few years ago and don’t want to get diabetes if there is anything I can do to prevent it.

Thanks Dummerchen for your reply about the app not distinguishing between natural carbs and added sugar – that makes much more sense! I find this 5:2 diet much easier than others I have been on over many years and will definitely continue to try and get my blood sugars down on a permanent basis.
