I am a type 2 diabetic using 2000mg of Metformin.

Of anything I've tried that is a "meal", nothing has spiked my blood sugar as much as a bottle of Soylent.

I really wanted to use Soylent but when my BS spiked to 350 after multiple 2h post meal tests, on multiple days, I just had to give up on the idea.

To give you an example, my BS will hit about 200 2h after a big bowl of Oatmeal and then settle back to 130-150 range.

If I eat just vegetables for a week, for example, my BS will move to the 90-120 range.

The glycemic index of a carbohydrate is a bad measure of its quality. A better measure is the degree to which it is fermented by bacteria in the intestines. Furthermore, there is research demonstrating that carbohydrates consumed without the phytonutrients that normally accompany them in whole food increase markers of oxidative stress and inflamation.

Soylent might be better than a frozen pizza or fast food, but in the big picture it's still shit compared to real food.
