Protein Spikes

I'll keep this brief. I follow a Keto diet, and whilst my sugars are much more controlled, I suffer from spikes after high protein meals, which I will usually consume twice a day for lunch and dinner (around 40-60g). I use a dual wave 50/50% over 2 hours, however I still spike. I've tried the wave over 1 hours, 1.5 and even 4, but nothing seems to work. Can anyone make a suggestion because it really makes me feel bad when I spike to 7.0/8.0 now days .

Thanks
