IF and Meal Replacements?

Hey! I'm still working away at eating healthier while doing IF. I have been struggling a bit with keeping up on what I am eating, but I am working on that.

I have been very curious about Soylent as of lately. (I'm not here to promote it, considering I haven't tried it before.) A friend of mine, another city away, bought some during Prime Day. Turns out they have flavors now!

Which is cool, because I have been told, by my SO, that there are people out there who just can't handle the act of eating. Apparently they find it annoying or uncomfortable? Anyhow, I think those types drink Soylent instead of eating all day. Which made me consider Soylent as something jammed packed with the right amount of nutrients for a person to simply survive on the liquid.

Which makes me wonder. Are there other brands just like Soylent out there? Has anyone following IF decided to just consume one or two meal replacements during their eating window? Are these products enough to sustain your body?

Thanks for any advice!!!
