So, after many times looking into this I've finally made the jump and decided to go with Huel for at least a few weeks to try it out, Also looked at cheaper alternatives but Huel ticks all the boxes for me so I would rather stick to it.
Current plan is to have it 2 meals a day, breakfast and lunch and it will vary when I'm working, essentially all I will be taking to work is Huel and a piece of fruit for mid shift snack so day shifts it will be breakfast and lunch, night shifts it will be lunch and dinner and I will eat my healthy(ish) meals at home.
Started to have some a couple of weeks back to give it a go so I've tried a few methods and personally I prefer the 5-600ml water and 90g in the shaker compared to adding other things, blending or leaving overnight, i find the grittiness adds to it and is actually quite pleasant.
For now I'm sticking with Huel Black for 2 meals and Huel protein as a drink if/when I fancy one but my partner does have some of the hot stuff (plus a mac and cheeze on the way) that I may try at some point in the future if I fancy something savoury.
