This depends on the kind of meeting you're having. If it's a negotiation with a counterparty, then absolutely schedule for right after lunch. It'd be better if they were a little insulin drowsy after lunch. Ideally you'd be buying them lunch, eating little (or mostly vegetables yourself) while they enjoy an expense account meal. 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)
