Vegetable choice and portion both matter when you are limiting carbohydrate. This reference compares raw vegetables on the same 100-gram basis so that water content, a large serving or an added sauce does not hide the difference. It is a shopping aid, not a recommendation to begin a ketogenic diet.
Fifteen vegetables on a consistent basis

These are USDA SR Legacy reference values, checked against the downloadable dataset on October 2, 2026. The dataset is historical, rather than a fresh test of your produce. The final column is arithmetic, not a guarantee about blood glucose or a universal regulated definition of “net carbs.” Cooking, draining, variety and prepared-food labels can change the numbers.

Choose by meal, not by a green color
Leafy vegetables such as romaine and spinach work well in a cold bowl. Wash them before assembling and use a separate container for dressing. A 100-gram comparison is useful for arithmetic, but a usual handful of leaves may weigh much less. Weigh one portion once if you need to understand your bowl.
Broccoli, cauliflower and cabbage bring a firmer texture. Roast or steam them as part of a meal rather than treating them as an unlimited replacement for every other ingredient. Oil, cheese and sauce change the meal's energy even if the vegetable itself has little carbohydrate.
Mushrooms, zucchini, peppers and eggplant can take the place of some of the bulk in a mixed dish. They do not reproduce the nutrition or cooking behavior of pasta, potatoes or beans. Keep the meal's protein food and other suitable components visible in the plan.

Starchy vegetables are a portion decision
Potatoes and other starchy foods contribute more carbohydrate per portion than leafy vegetables. That does not make them unhealthy or forbidden for everyone. A strict prescribed plan may limit them; a less restrictive plan may include a measured serving. Check the whole meal and the guidance you are following rather than sorting every food into good and bad.
For a mixed bowl, record cooked rice, vegetable, sauce and toppings separately. “Cauliflower rice” does not establish that a packaged dish is low in carbohydrate: it may include another starch or a sweet sauce.
Three preparations that keep the comparison clear
- Steam, then finish. Cook broccoli or cauliflower until the texture suits the meal. Measure any oil or sauce separately so you can repeat the serving.
- Roast a tray. Cut zucchini, peppers and eggplant to similar sizes. Give the pieces room and turn as needed; the appliance and cut determine time.
- Assemble a cold side. Combine washed cucumber, radish and leaves. Pack dressing separately and keep perishable components cold until eating.
Use the recipe catalog to inspect actual ingredients, then place a suitable meal in the planner. A recipe tag helps browsing; it does not certify that the recipe fits a medical carbohydrate prescription. The macro calculator explains totals without replacing clinical advice.
Questions about the list
Should I count total or net carbohydrate?
Use the method specified by your clinician or plan. Do not switch methods to make a meal appear to meet a target.
Can I double a serving?
Double its listed quantities in your arithmetic too. The same vegetable can contribute different totals in a small side and a large main dish.
Do frozen vegetables count?
Check the product label, especially for sauces or added ingredients. Plain frozen vegetables can be practical; their prepared weight may differ from this raw-food reference.
Is this advice to start keto?
No. Restrictive diets can be unsuitable in some circumstances. Discuss them with a qualified professional, especially when medication, pregnancy or a history of disordered eating is involved.
