I've emailed info.soylent about this before signing up for the discourse page, actually.
I would like to see a formulation for women! Currently I use Soylent as a highly regimented diet. It's amazing. I find each bottle very satisfying without spurring my appetite to never stop eating--which is what happens with traditional food for me no matter how full I am.
Right now, I am consuming 4 bottles per day on my work day and eating traditional food (that I'm trying to consciously make healthy choices about) on the weekend.
I am 5'4" and 200lbs so 1600 is the amount to lose weight. But get this, if I were 5'4" and 140lbs my recommended calories to simply MAINTAIN my weight would still be 1600.
I will either have to add in daily rigorous exercise, wean myself onto more traditional foods or be perpetually 20% deficient if I continue a Soylent diet.
I think Soylent is wise to avoid claims about weight loss. What I am doing is a risk I understand. However, I think many healthy women would be interested in this product if it reflected a healthier diet for them.
I think I read somewhere (I don't know where) that something like 15% of Soylent drinkers are women. I'll bet female drinkers would rival men if there was soylent formulated for their specific needs--possibly more.
