Overall health will certainly help. It's well known that a healthy body will have a positive effect on the brain, and that things like eating breakfast can have a positive effect on outcomes later that day. However, I have a feeling that these factors are very small, and have more of a cumulative effect than any immediate effect on any specific day.
I currently have a score on https://osu.ppy.sh/s/239943 which is 100k higher than my other scores (roughly 9% accuracy above my average score). It will likely take me months before any one of my average scores will match that level. It's certainly possible that I could beat that score next time I play that map, but the chances are extremely small.
Unless you're entozer, everyone finds jackhammers hard.
