I am thinking the hardest thing to overcome at the beginning for you might be the taste and texture of it, since it will be quite different than what you’re used to. Rest assured, that this was the situation for many of us, and after a few days the texture was not an issue.
For taste, there are many ways to easily flavor it up. Using a blender is probably the best way to mix it, IMO. It makes it more smooth and consistent. Also, it allows you to add a wide range of stuff.
Go to additives for my Huel are: banana, frozen berries, natural peanut butter (with no added sugar), raw cashews, no sugar added apple sauce, cinnamon.
If you like the taste of strawberry and/or blueberry, frozen berries make an easy and low glycemic index addition to vanilla Huel. And since they are frozen, you don’t have to worry about them going bad. You can get them in big packages at reasonable prices. And berries don’t have a lot of calories. Applesauce is similar. I find it’s much easier to spoon applesauce in rather than cut up apples, since blending an apple results in the same thing anyway. And applesauce lasts longer in the fridge.
A favorite of mine is 2 or 3 scoops Vanilla Huel + 2 tablespoons of PB + 1 or 2 tablespoons of applesauce + sprinkle cinnamon.
Some people find it nice to mix Huel in some kind of milk (cow, almond, soy, any milk really) or a half milk + half water mix.
So, what I am saying is that if you don’t like the vanilla huel + water simple mixture, don’t fret. With a little extra shopping for easy ingredients that are not too expensive, you can flavor it up and add variety.
Personally, I have found that I prefer my Huel drinks more diluted. But some people like it thicker. Most of us prefer it cold, though.
