Is that 1.5-2 litres on top of your Huel?
For me I have 500ml of water with every 100g of huel. I have that 4 times a day, so already 2litres of water.
I then also have probably another 1.5 litres on top / a few coffees here or there for my gym sessions/work. So 3-4 Litres total, which now that i say it out loud seems a lot but it feels right for me.
Huel has enough fibre already, even at my slightly reduce calorie intake (try to lose weight), so I can tell from google.
I guess I do spend more time on the loo than before but in all honesty, I just take my sweet time with it now. Before I was more of a push, get it all done with in one go kinda guy but now I’ve learnt to not force it one bit.
it sounds silly but look at this for the home: http://www.squattypotty.co.uk I’ve personally not got this but I’ve had friends genuinely rave about it.
