Huh, kinda a bummer to find out that that is a bug and not a feature. But yeah, if it wasn't intended to be that way I can understand.
It was actually quite funny, when I was frenzying for 3 days and nonstop feed a girl the extra caloric shakes. Which gave basically a mil calories each.
With which I even skipped some blob stages because of the rapid weight gain.
Best part was especially the OF weight graph going stonks to the moon. xD
EDIT: Actually I would kinda like it, if we could find a compromise and not straight up nerf the High Caloric Nutrient, because they do cost 50 points each and you need two for the strong shake, while the Dizzy Concentrate only costs 20 credits.
Which puts 100 points against 20 credits. Or 5-10 daily tasks Research against 2-5 daily task Lab.
Maybe actually implement something that creates a reaction with the concentrate, like the ones I experienced with the feeder.
