The excerpt quoted from Diabetes UK earlier was somewhat selective by the OP.
Diabetes UK also say ”Some people eat fruit infrequently, but have larger portions when they do eat them, which can mean the carbohydrate portion in one sitting is quite high. It is easy to consume a lot of dried fruit, grapes and tropical fruits in one go, for example, and this can have a bigger impact on blood glucose levels.”
They also warn that you need to spread out fruit intake over the day, and to be wary of smoothies or dried fruit.
A lot of their information about cutting out sugar is suggesting people cut out refined sugar sources first. My DM was recently diagnosed as diabetic and I can tell you now, she was advised to be careful with her fruit intake (she likes satsumas, grapes, and pineapple - all very sweet!)
@BIWI has been a fantastic font of knowledge on the dieting board and absolutely knows her stuff. And also, she doesn’t lecture people….
I switched to low carb/keto and the difference in my body is remarkable. Not just the weight loss - I’m no longer bloated and my ankles/legs have stopped swelling up and retaining water. It happened literally overnight, before I lost any weight.
I have discovered my body is so much happier with fewer carbs and little/no sugar.
The diet you suggest OP would have be puffing up instantly and feeling sluggish, bloated etc.
I appreciate you’re passionate about the subject OP but nutrition is nuanced and there are various ways to eat healthily. What is healthy for me might not be right for someone else, and that’s ok.
