I’ll let the experts answer the nutritional questions but what I would strongly suggest is phasing Huel into your diet more gradually. Whilst I haven’t personally experienced any issues there are plenty of folks here who have found a number of side effects, which would of course be the same with any other dramatic change in diet.
Far and away the main points seem to be around the digestive system which would of course make sense. Flatulence and worse!
I’ve been having a single huel black a day for the last couple of weeks and just started adding in a second huel black each day. Eventually I intend to work up to a mostly huel diet, running at a deficit for fat loss purposes but despite not encountering any issues thus far I’m still building up to that gradually.
If the time you save in shopping and food preparation is spent running back and forth to the loo then it would appear to have little benefit!
