Pescatarian Keto Diet: Definition, Food List, and Meal Plan

Pescatarian Keto Meal Plan

A lot of people think that to properly follow a keto diet, you need to eat meat. Meat is nutrient-dense, low-carb, and delicious. That’s a fact. However, meat does not sit well with some people for personal reasons. That’s another fact.

If you’re deciding to go meat-free on keto but want more flexibility than eating just low-carb vegetables and fruits all year round, a pescatarian keto diet might be the right option for you. This way of eating will put you in ketosis when done right.

Learn what the pescatarian keto diet is, some of its benefits, and a list of foods and meal ideas to kickstart your journey.

What is Pescatarian Keto?

The pescatarian keto diet is a sub-diet or variation of the standard keto diet. With that, your diet consists of fish, other types of seafood, vegetables, and fruits. Fun fact: The term “pescatarian” comes from the words “pesce” which means fish, and “vegetarian.”

As a general rule, choose only pescatarian foods that are very low in carbohydrates. Limit your daily total carbs to only 20-50 grams. Like all variations of keto, avoid grains and high-carb processed foods.

Thankfully, most fish and seafood contain just a small number of carbs to zero carbs for a 4 oz (or 113 grams) serving. The best low-carb veggies are those that grow above the ground such as leafy greens.

Sometimes, you can eat eggs and dairy products as a healthy way to add more variation to your diet. I also think that on days when you don’t have seafood in the fridge, eggs are a cheap alternative to get protein and fat!

Why go pescatarian on keto?

One thing is for sure – that this keto diet variation will help you enter and maintain nutritional ketosis. This is especially important if you’re using this metabolic state for health and fitness reasons. Read this article for more information on ketosis.

Some people choose to follow a pescatarian diet for ethical reasons as well – like opposing meat slaughter. Or maybe you’d just like to try something new and experience its unique effects on your body!

(I’ve done variations of the keto diet and based on experience, I find that my body tolerates and responds well to some foods than others. What I’m saying is, go ahead and experiment.)

Pescatarian Keto Food List

A keto diet for pescatarians includes the following foods. Check out their total carb count per 4 oz serving below. I’ve taken the details for “Fish” and “Seafood” from Maria Emmerich’s The Carnivore Cookbook.

You may also notice that “Fruits and vegetables” and “Nuts and seeds” have a higher total carb count. That’s because they contain dietary fiber which is counted in the total carbs. Dietary fiber cannot be digested by your body and will not impact your blood sugar. You can research the net carbs of these plant-based foods individually.

These are just some ideas to get you started. At times when you’re too busy, you can try canned seafood. When I have that, I usually eat it with boiled eggs for a more satisfying meal.

Storage Tip: Based on experience, fish and seafood tend to spoil more quickly. If you’re buying a big batch, I recommend storing them in the freezer at 40°F or lower. And if you’re going to do batch cooking for the entire week, also keep your meals in the freezer.

To defrost, place the raw fish/seafood or cooked meal at the bottom of the fridge overnight.
