We are all different and what works for one may not work for another . I found that too much protein can turn into too much glucose in the blood . I found I had to keep my Protein to 0.8 gram of the weight I wanted to be so for example 64 gms if I wanted to be 80 kilos . I increased fats ( olives and nuts ) without in general terms increasing blood sugars and helped with saity. I also try to eat 16:8 (i.e. only eat in a 8hr window )and finish before 6 pm . I find that if I am dehydrated my blood sugars increase and in this hot weather I am having to drink about 3 litres of water... usually I drink between 1 and 2 litres.
Hope this helps
