Lowest-carb foods, ranked
For low-carb and ketogenic diets, the priority is keeping total carbohydrate low while still eating well. The foods below contain the least carbohydrate per 100 grams in our USDA-sourced database — predictably, proteins and fats cluster at the very bottom of the carb scale, alongside non-starchy vegetables. Use it as a quick reference for building meals that stay within a carbohydrate budget.
