Use of Huel before / after gastric bypass?

Does anyone have any thoughts on the use of Huel as food before / after a gastric bypass?

Would it contribute to the “liver shrink” diet that you have to go on before such a procedure?

Thanks

We kind of covered it here: http://huel.com/pages/faq#stomach

Huel will be fine, but I would have smaller portions spread through the day
