I'm not against carbs, I just like macro ratios more like the earlier versions. Lots of carbs and polyunsaturated oils are in the literature as triglyceride boosters. If they offered a version with the fish oil back in and the old protein ratios I'd be interested, especially if the replaced the rice protein with the collagen or fish meal from the bait fish the oil came from. At least as sustainable as giant fields of rice and safflower and probably lower in heavy metals too. Rice sucks up the cadmium.
There are several other Soylent mods out there. Super Body Fuel, Huel, and Tsogo are a few others I tried. Not a drink, but Meal Squares and Greenbelly Meals are a similar idea too. No idea if any of them meet your needs. I think there was a website that had a huge list of meal replacements.
