We'll also explore some keto-friendly alternatives to clams, ensuring a variety of nutrient-rich meal options.
TL;DR
Are Clams Keto-Friendly?

Yes, clams are considered keto-friendly. Their nutrient profile is favorable to the standards of a ketogenic diet, primarily due to their low net carb content. One hundred grams of clams contain just 3.57 grams of net carbs, making them a suitable option for those following a keto diet.
Can You Have Clams on a Strict Keto Diet?
A strict keto diet typically involves consuming less than 20 grams of carbs daily. Considering that 100 grams of clams contain just 3.57 grams of net carbs, it is easy to incorporate this seafood into a strict ketogenic meal plan while maintaining ketosis.
Now, if you're someone who prefers a more laid-back low-carb eating regimen, don't fret. Clams are still a delicious and nutritious option for you! In fact, you'll love how easily they fit into your diet and add a boost of flavor to your plate.
Carbs In Clams
Clams are a keto-friendly food as they contain only 3.57 grams of net carbs per 100 grams. Additionally, they have a low glycemic index of 27[source], which means that the carbohydrates they contain are released into the bloodstream slowly.
This leads to a steady rise in blood sugar levels, reducing the risk of a sudden spike. In contrast, foods with a high glycemic index are quickly digested and can cause a rapid increase in blood sugar levels. Therefore, clams are a great option for those following a ketogenic diet.

Health Implications of Clams on a Keto Diet
Clams are a highly nutritious food with essential nutrients such as protein, iron, zinc, and magnesium. They are also a significant source of vitamin B-12, which is vital for proper nerve function and the production of DNA and red blood cells.
However, it's worth mentioning that clams can be high in sodium, which, when consumed in excess, might not align with everyone's dietary needs or health goals.
Incorporating Clams into Your Keto Meal Plan
- Clams can be a versatile addition to a variety of dishes. Consider adding them to your favorite low-carb soup or stew for a protein boost.
- For a quick and simple meal, sauté clams in garlic and olive oil, serving them atop a bed of spiralized zucchini noodles for a keto-friendly "pasta" dish.
- Clams can also be a tasty addition to a keto seafood salad, combined with other low-carb seafood options like shrimp or crab.
Keto-Compatible Alternatives for Clams
- Shrimp can be a suitable alternative to clams, with a similar net carb content, making them equally keto-friendly. Shrimp can be utilized in a wide variety of dishes, including stir-fries, salads, or as a stand-alone protein source.
- Mussels, like clams, offer a low-carb seafood option that fits into a keto diet plan. They can be enjoyed steamed with some garlic and herbs, or incorporated into a keto seafood stew.
- Scallops, another low-carb seafood option, can act as an excellent replacement for clams. They provide a unique taste and texture, and can be seared and served over a bed of sautéed spinach for a keto-friendly meal.
- Salmon, although a different type of seafood, is packed with healthy fats and protein, and very low in net carbs. It can be grilled, pan-seared, or even baked, providing a hearty alternative to clams.
Concluding Thoughts on Clams and Keto
With their low net carb content, clams fit nicely into a keto diet, providing a protein-rich, nutrient-dense option that can be enjoyed in various ways—from stews and soups to salads and stir-fries.
Their high content of essential minerals like iron, zinc, and magnesium, coupled with the valuable vitamin B-12, make them a beneficial addition to your diet.

Cast Iron Keto's Editorial and Research Standards
Certain rare or exotic food items may not have nutritional profiles in the FoodData Central database. If an exact match is not found in the FoodData Central database, then, the Cast Iron Keto team utilizes a three-prong approach to provide readers with the closest relevant nutritional data, where possible.
First, in the event that nutritional profiles for a rare or exotic food item is not available in the FoodData Central database, we investigate alternative names for that particular food item and use that data, when possible. Second, in cases where no alternate names exist, Cast Iron Keto will use nutritional data for a close relative or similar food item. Finally, if no close relatives or similar items exist, we refrain from publishing nutrient data tables.
When making dietary or health decisions based on FoodData Central's data, we suggest readers consult with a nutritionist or other health experts, particularly if the food in question has a significant role in your diet or if you are using the food item to treat any health disorder(s).
Furthermore, it is important to note that even if a close relative or similar item is used to approximate the nutritional data, different food items can have varying levels of nutrients due to factors such as soil quality, farming practices, and regional differences.
