Corn on the cob is a summertime classic, and creamed corn pairs perfectly with barbecue. But if you’re on a ketogenic diet, corn is a food you may want to think twice about.

Corn Nutrition Facts

Corn is considered a starch, says Scott Keatley, CDN, FAND, lead clinical dietitian and cofounder of Keatley Medical Nutrition Therapy, based in New York City. “It’s a high-energy carbohydrate,” he says.

You can enjoy corn in several ways: fresh on or off the cob, frozen, or canned.

One cup, or 145 grams (g) of fresh, raw yellow sweet corn contains:

  • Calories 125
  • Protein 5 g
  • Fat 2 g
  • Carbohydrates 27 g
  • Fiber 3 g
In addition to a surprising amount of protein, corn offers B vitamins and important minerals such as iron, magnesium, and zinc.

Can You Eat Corn on Keto?

Since corn is higher in net carbohydrates, it can be difficult to fit it into a keto diet and remain in ketosis. You may choose to avoid corn on any low-carb diet, given its higher carbohydrate content.

Net carbohydrates are the carbohydrates in food that are ultimately digested and absorbed by the body, thereby affecting blood sugar levels. You can calculate a food’s net carbohydrates by subtracting its total fiber and sugar alcohol content from its total carbohydrate content.

 People following a keto diet often use this number as a guide to help them stay in their carbohydrate range and remain in ketosis.

It’s possible to enjoy a very small portion of fresh corn, about 1 or 2 tablespoons, in a low-carb diet such as keto, says Keatley. But even that amount accounts for a significant portion of your daily carbohydrate allotment. If you’re wondering, “Can I eat corn on the cob on a keto diet?” the answer is no.

Keto Recipes With Corn

Although corn isn’t typically recommended on a keto diet, some recipes make use of corn in inventive and keto-friendly ways:

  • Low-Carb Mexican Street Corn Salad This recipe from That Low Carb Life cuts the corn content with cauliflower for a lower-carb twist on this favorite side dish.
  • Low-Carb Keto Cornbread Chopped baby corn provides corn flavor, while almond and coconut flours help keep the carb count of this KetoConnect recipe in check.
  • Keto Corn Tortillas Made with mostly almond flour, these Earth & Oven tortillas get their corn flavor from a small amount of corn flour.
When you’re craving corn and following a keto diet, you can also reach for fresh, air-popped popcorn as a snack because it has fewer carbs than fresh corn — 1 cup of popped popcorn has just 5 g of net carbs.

 You can also choose to pop it with or toss it in a healthy oil to meet your calorie and fat needs, says Keatley. Want something sweet? He recommends sprinkling it with cinnamon or a small amount of nonnutritive sweetener.

The Takeaway

  • Corn is a starchy, high-energy carbohydrate containing approximately 24 g of net carbohydrates per cup, making it difficult to include in a keto diet and remain in ketosis.
  • While a full ear of corn isn’t keto-friendly, experts say you can consume very small amounts (1 to 2 tablespoons) or opt for air-popped popcorn as a lower-carb alternative.
  • To satisfy your corn cravings, try recipes that use cauliflower, baby corn, or corn extract to mimic the flavor you desire while keeping the total carbohydrate count of your meals low.
