One things I was thinking of is trying to schedule meetings right after lunch. I'm basing this on the research of judges being more lenient after lunch. https://www.theguardian.com/law/2011/apr/11/judges-lenient-b...
Switched on its head, I prefer morning interviews because I can really focus on the candidates without thinking of (or being annoyed for stopping work on) a deep problem I began working on. If a sales person calls me in the morning, I'm more likely to answer and have a conversation.
On the other hand if it's an internal meeting with your team, you want to get them at peak alertness, 10-11 (people settle in for the day, but not hungry for lunch yet), 230-4 (the post lunch blood sugar swing has settled down but people aren't itching to leave just yet)
