Does Lettuce Have Carbs? A Detailed Look at the Carb Counts in All Lettuce Varieties

Does Lettuce Have Carbs?

Lettuce is one of the most popular low-carb foods. It's crunchy, hydrating, and nutritious - making it a staple ingredient in many keto-friendly recipes. But does lettuce really have zero carbs? Or does it contain some hidden carbohydrates?

The answer is - it depends. There are many different types of lettuce, each with slightly different nutrition profiles. Some are lower in carbs than others.

Here's a detailed look at the carb counts for different lettuce varieties:

Iceberg Lettuce

This is the classic lettuce found in most salads and on burgers. Iceberg lettuce is one of the lowest carb options.

One cup of shredded iceberg lettuce contains:

• Calories: 10
• Net carbs: 1 gram
• Fiber: 1 gram

With just 1 gram of net carbs per serving, iceberg lettuce can be enjoyed freely on a ketogenic diet.

Romaine Lettuce

Romaine is another very popular lettuce variety. It has slightly more nutrients than iceberg, while still being very low in carbs.

One cup of shredded romaine contains:

• Calories: 8
• Net carbs: 1 gram
• Fiber: 1 gram

Romaine and iceberg can generally be used interchangeably in keto recipes.

Butterhead Lettuce

Butterhead lettuce includes Boston and bibb lettuce varieties. It has a more delicate, smoother texture than other lettuces.

One cup of shredded butterhead lettuce provides:

• Calories: 7
• Net carbs: 1 gram
• Fiber: 1 gram

With just 1 gram of net carbs per serving, butterhead lettuce is excellent for a ketogenic lifestyle.

Leaf Lettuce

Leaf lettuce comes in many varieties - green leaf, red leaf, oak leaf, etc. They all have a similar nutritional profile.

One cup of shredded leaf lettuce has:

• Calories: 7
• Net carbs: 1 gram
• Fiber: 1 gram

Again, with just 1 gram of net carbs per one-cup serving, leaf lettuce is a great low-carb choice.

Spinach

Spinach is not technically a lettuce, but it's commonly used in salads. It does contain slightly more carbs than regular lettuce.

One cup of raw spinach has:

• Calories: 7
• Net carbs: 0.4 grams
• Fiber: 0.7 grams

At less than 1 gram of net carbs per serving, spinach can also be enjoyed on a keto diet.

Spring Mix Lettuce

Spring mix is a blend of young lettuce varieties like baby spinach, arugula, radicchio, and red leaf lettuce.

One cup of spring mix contains:

• Calories: 8
• Net carbs: 0.9 grams
• Fiber: 0.5 grams

With less than 1 gram of net carbs per serving, spring mix is a tasty lettuce option for keto salads.

Endive is a bitter green that is often added to salads for a nutritional boost. It contains slightly more carbs than lettuce.

One cup of raw endive has:

• Calories: 4
• Net carbs: 1.5 grams
• Fiber: 1.2 grams

At 1.5 grams of net carbs per cup, endive is still low enough in carbs to include in moderation on keto.

Radicchio

Radicchio is another bitter leafy green. It looks like red cabbage and adds color to salads.

One cup of shredded radicchio contains:

• Calories: 9
• Net carbs: 1.3 grams

Tips for Enjoying Low-Carb Lettuce on Keto

Here are some tips for incorporating lettuce and greens into a ketogenic lifestyle:

Focus on the Lowest Carb Varieties

Stick to the lettuce varieties lowest in net carbs like iceberg, romaine, butterhead, and leafy greens. These all contain 1 gram of net carbs or less per serving.

Avoid High Carb Add-Ons

Avoid adding high-carb toppings like croutons, sugary dressings, fried wontons, and tortilla strips which can drastically increase the carb count.

Watch Portion Sizes

Even low-carb lettuce can add up if you eat large portions. Stick to around 1-2 cups per serving.

Balance with Other Low-Carb Veggies

Combine lettuce with other keto-friendly vegetables like cucumbers, tomatoes, peppers, and broccoli.

Add Lean Protein

Top your salads with protein sources like grilled chicken, shrimp, hard-boiled eggs, or avocado to turn it into a hearty, keto-friendly meal.

Make Lettuce Wraps

Use large lettuce leaves in place of tortillas or buns for low-carb sandwich wraps.

Try Lettuce-Based Soups

Blend low-carb lettuces into creamy soups and chowders for a unique, ultra low-carb dish.

Health Benefits of Lettuce on Keto

Lettuce provides some key nutrients and health benefits, in addition to being low in carbs:

Minerals

The Bottom Line

Lettuce and leafy greens contain minimal carbohydrates, ranging from 0.4–1.5 grams of net carbs per serving. This makes them an excellent low-carb base for salads and meal prep on a ketogenic diet.

Focus on low-carb lettuce varieties like iceberg, romaine, leaf lettuce, and butterhead. Avoid heavy carb-laden toppings and enjoy lettuce wraps, soups, salads, and other creative recipes to reap the hydrating and nutritional benefits.
