Hi there, welcome to the Huel family and to the forum!
When we say a ‘meal’, we mean 500kcal, this is about 125g of Huel Vanilla.
The scoop is really just a means of getting your Huel efficiently out of the pouch and isn’t an accurate way of measuring your Huel consumption - if accuracy is what you are after. If you are very enthusiastic with your scoops then you will scoop more out and visa versa! We estimate that each scoop is approximately 38g or 152kcal (3.3 x 38g scoops).
However, a meal is a much or as little as you want! If you want to eat 200kcal of Huel or 1000kcal of Huel in one sitting then you can! That’s one of the great things about Huel, it gives you the ability to monitor your calorie consumption very accurately.
I hope this helps, if you have any other questions then fire away.
