I’m assuming you mean with a DIY recipe? Otherwise pick up an order from the campaign, and the current delivery time will be in December!
For DIY: Though you will face a couple small differences between genders, any starter recipe will give you a pretty good idea of where to start.
Also check out makesoylent.com; tons of recipes and also includes nutrition profiles for females as well.
For comparison; I’m 6’1, male, 160lbs, relatively sedentary, and I consume about ~1600 to ~1800 calories a day. You might be okay with starting at 1400 or 1500, but obviously if you end up finding yourself pretty full after less than that, well you have left overs.
Good luck, and welcome to the Soylent discourse board!
