Common questions
What counts as low-carb for meal prep?
Definitions vary by protocol, and the right target depends on you rather than on any single number — a registered dietitian (RD/RDN) is the right person to set one, particularly if you are managing diabetes, epilepsy, or another diagnosed condition. What we can tell you is what is on this page: the recipes here mostly land in the 8–18 g net carbs per portion range, with cauliflower or zucchini standing in for rice and pasta. Every card shows its own figure, so you can match them against whatever target you are working to.
Do low-carb meal-prepped meals freeze well?
Most do: protein + roasted veg + cauliflower rice freeze for 2–3 months. Skip leafy salads from frozen-portion plans — assemble those the morning of.
Will the Instacart cart respect keto substitutions?
Yes — when the recipe specifies cauliflower rice, zucchini noodles, or shirataki, Instacart matches the keto product variant. Tell the planner your retailer preference (e.g., Costco, Target) and the cart routes there.
How is “net carbs” calculated on these recipes?
Net carbs = total carbohydrates − dietary fiber (and, per some protocols, − sugar alcohols). The recipes here use the USDA FoodData Central values for total carbs and fiber, subtracted per portion. This mirrors the definition used by the Harvard T.H. Chan School of Public Health nutrition source — see the Sources panel below for the primary references. Consult a registered dietitian (RD/RDN) before adopting a ketogenic diet for a diagnosed condition (diabetes, epilepsy, metabolic disorders).
