Yes, obviously. I'm stunned that it needs to be said, but since it apparently does:
1. You propose taking a medication regularly which is probably completely unnecessary, and paying for it regularly. (This was worse with "metabolism boosters" etc. since the patient would be paying for the medication to have the privilege of eating more, and thus paying more for the extra food.)
2. Knowing what you eat, and being able to denominate it in calories, is knowledge. I thought we were hackers here? My experience has been that ordinary people have some truly absurd ideas about how fattening certain things are or aren't, or about how much they're actually eating, or about what healthy daily intake ranges, portion sizes etc. look like. (They also have absurd ideas about how much it costs to "eat healthy", as well as about the connection between "healthy" food and caloric intake.)
