Royal Rice Pudding was the best flavor ever and I've worked thru all the standards.
It's even better than my previous favorite Awesome Apple Pie.
I also had no trouble with digestion/gas afterwards (which I had with almost all of them, except with Macchiatto and AAP to an only minor, but still annoying degree), which might be due to the lowered protein content.
Getting enough calories in the first place to build muscle is a more important issue for me, than hitting some mystical macro-ratio target (I have virtually no sensation of feeling hungry ever, which is a downside of being 'metabolically flexible', I guess).
I was disappointed, that I couldn't vote for RRP to become part of the permanent line-up.
To the question:
I don't have an opinion about the reduction in Palm Fat (was that for Hippie reasons or health reasons?).
I don't know what GI is.
The recipe seems to be the first, that I can digest without any problems at all,
so please go ahead with this.
I'm never not satiated, really.
Energy levels don't change dramatically after a meal for me anyway, unless I go full pasta, after which I get tired and sluggish.
I think it might dissolve better in water, but I'm not entirely sure.
