I’m 26, for context. When I use to eat sugar like a madman, I use to feel just like you, so perhaps there could be other factors impacting your mental sharpness. I have a few questions for you to answer to yourself: 1 - How fit are you? (Cardio and strength) 2 - How is your sleep? 3 - How often do you practice programming / play with greenfield software projects outside of work? There could be more questions, I am not a specialist, but I have felt just like you described when I use to eat more sugar-based food than I was supposed to.
