Another advantage of Huel is that you do get more fluid intake - so if you're not very good at drinking a lot of water, it can help with that too.
Oh I'm restarting as I was doing a lot of travelling over last two weeks so doing three weeks from today, only other things I'm allowing myself is a cup of coffee a day along with theanine and creatine as my supplements. I'll also be able to "brag" how I once went vegan for three weeks
It's not that calorie dense so you'd have to mix it with milk (unless dairy is not an option) as to add significant calories you'll have to eat a lot of the stuff, but perhaps still cheaper than buying MRPs from supplements stores.
What do you class as warm? I can do one for science, normally just make them with room temperature water from the Brita filter and down them.
