You really can't think of a situation in which skipping a meal (or maybe several) is the best choice to optimize someone's happiness or productivity?

Example: In my case, I don't particularly feel like cooking breakfast if I get up early to play golf or hike, and doing either while hungry is unpleasant. Soylent solves that problem, and I prefer it to Clif bars, which is what I would have used before Soylent.
