Not being snarky, but is this truly "better" than a single weekly injection - 10 seconds and done for the week? I do think our wider society sees medications for overeating as "cheating". Perhaps we might benefit from rethinking that.
I would compare something like scale measurements to sex education. If kids were all exposed to some period of measurement of foods to learn what they were eating, it would stick. Studies show that ANY form of tracking causes people to make more mindful choices. Everyone I know personally that is taking these drugs uses it as a crutch entirely. They take it and make even worse food choices than before. It's very sad and I worry about the next issue they will cause with this behavior to then stack another medication on top.
I started doing it mostly out of curiosity, and it turned out one of the meals I thought it was high-calorie was actually lower than my other meals.
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.)
I think "perfect is the enemy of good" applies here. People en masse are not controlling their intake. They just aren't. They can't do it. We can rage about it and criticise - and many do for all the good that's doing - or we can explore options. Medications with few side effects have some appeal here. Evolutions will likely reduce those. Eventually that will not be a strong argument against the medication option is my prediction.
