In my case nearly no body fat. Thanks for the link. Lets say prediabetes is diagnosed. What now? Kind of really hard to figure out what to do. Tried daytwo by the way, kind of accurate description. So trying to avoid food that produces a spikes. Not sure if that is enough. By the way one interesting thing. After hard workouts the responses are much better. So maybe one could just follow mothers advice, eat healthy and do sport.

IANAD, but AFAIK all you can do is eat better and exercise. Honestly the eating better is like 85% of it anyway.

I've been in the same boat for years now and I never eat just carbs by themselves, and I try to never exceed 35 carbs in a single meal. A lot more meat, a lot less bread. For me I'm almost better off eating candy than I am soft white bread (although neither is a good idea of course).

I went keto for a while and that did seem to help, except I do really poorly with high fat foods. Now I just try to balance everything, lean high on the protein, and limit carbs to 35 per meal.

One possibility can be Monogenic diabetes (aka MODY). Certain forms of it are more like a slowly onsetting type 1 diabetes. It can often be misdiagnosed.
