2000kcal of ‘black’ Huel would give you 220 grams of protein. I work out hard several times a week and 220g of protein would be a complete overkill.
Most research shows that consuming more than 2.2g of protein per 1kg of lean body mass doesn’t show any benefits as 2g is already a lot. I actually surpass my protein needs already by consuming normal Huel.
Maybe Huel made a special new formula just for Hafþór Júlíus Björnsson, haha.
Several complete food companies have different formulas so Huel making 2 powders which are different seems logical. The natural ingredients in the black version can be quite different from the normal v3.
