400 calories is 100g of huel.
It’s best to weigh it if you need to be exact.
But until you get kitchen scales, one scoop, if you pack it in then level it off is about 40g.
So yes, 2.5 scoops is 400 calories.
It’s pretty difficult to get it that accurate though, especially the half scoop!
Depends really. If you heap the scoops you could easily make a 600 calorie shake instead of 400… and if you’re a short-arse like me, 200 calories is 15% of my daily allowance so quite a lot
Edit: saying that though… I don’t calorie count. I do weigh my huel though. I just don’t count the rest of my calories. I probably should. Then I might actually lose some weight!
