Well, let’s try and adress a few of your questions!
First up, YES! Huel travels very well. I often go to work with 3 resealable small bags with 3 scoops ( for me, a main meal with 550ml of water) in each. That’s an entire days worth for me, ready to add water, shake and drink. It washes off so easily with water, so yeah, Huel is very easy to transport. If you prefer a few less lumps (I’ve never found a problem with the lumps) then a blender is the way to go, in which case storing in the fridge is the recommended way to keep it, so a little less travel suitable. Honestly, a vigourous shake for 15 seconds, and I’ve not found the lumps to be a problem, just be sure to put water in first then empty a bag into the shaker (premeasured bag, not an entire Huel bag!)
Secondly, is it more cost efficient than regular food, for the average student, NO. noodles and cheap vodka cost hardly anything, and that is what I lived off when I was a student!
However the Vegan side of things changes that. Quorn is relativly cheap, but if you cant get on with it then you need to look at other options. How much are you spending on fruit and vegtables atm? You didn’t state your age, so I’ve made a guess at 21, and so your calories are around 1650-1700. Huels “week” is based on 2000 calories, so you’ll last longer (so pay less!) but a months worth for 2k is 162 quid. I’d say you’ll be spending 35 a week ish for your complete food using Huel. Weigh that up compared with what you spend atm, and see.
Regarding getting bored easily, Huel currently comes in 6 different flavours (4 flavour pouches, original vanilla, and unsweetened/flavoured). You can also add your own flavours to the mix, a few of the forum users have experimented with different sweet and savoury options (things like expresso and chocolate are popular, but I’ve seen people try chilli sauce!) Making your own savoury options might be an idea using things like cinnamon powder, ground ginger and the like to keep it vegan (A fair few sauces are not vegan friendly).
Hopefully this should give you information you require to make a choice that works for you. If you need more help / have more questions, pop in a reply!
