The Ultimate Keto for Pescatarians Guide

Looking to cut your consumption of carbs and meat? Then, the pescatarian keto diet may be exactly what you are looking for. Combining the keto diet with pescatarianism creates a unique low-carb eating plan that emphasizes seafood, eggs, and dairy while excluding other meats. This approach allows individuals to achieve ketosis, where the body burns fat for energy, without sacrificing protein intake. It is a misconception that you cannot adopt a ketogenic lifestyle without eating meat. Vegetarian and pescatarian keto do not necessarily require a restrictive diet. In fact, there are many varied and delicious foods you can eat as a keto vegetarian or pescatarian.

What is Pescatarian Keto?

A keto pescatarian diet is a meal plan that incorporates the rules of a ketogenic diet and carefully follows a vegetarian lifestyle. As the name suggests, this is an eating plan that combines the rules of the currently popular ketogenic diet with a pescatarian lifestyle. The Pescatarian Keto meal plan is a vegetarian diet that implements the consumption of fish, seafood, and plant-based foods to increase proteins while restricting carb intake significantly encouraging the body to enter a state of ketosis. This diet is typically used by those who aim to lose excess pounds but don’t want to consume animal flesh other than fish and other seafood.

The pescatarian keto diet is an eating plan that mixes pescatarian and keto diets to get the benefits of each. Both the pescatarian diet and the standard keto diet offer a range of health benefits.

Understanding the Basics

Ketogenic Diet (Keto)

A ketogenic diet is a low-carb meal plan that calls for an intake high in fats, moderate protein, and very low carbohydrates - 70-80% of daily calories come from fats, while 20-30% of daily calories come from protein, and carb intake is minimal. A person following a pescatarian keto meal plan should only consume 20-50g of carbs per day. Proponents of this eating plan state that this diet pushes your body into a state of ketosis, where it uses fat as its primary energy source instead of glucose as it normally does.

Pescatarian Diet

When it comes to the pescatarian diet, please do not confuse it with a vegetarian diet. While these two eating plans are quite similar there are some subtle differences between them. The pescatarian diet can be considered a variation of the primary vegetarian diet. According to WebMD, this is essentially a fish-based diet where people stay away from all other types of meat and poultry.

Pescatarian Keto Diet

On the other hand, while those on a ketogenic diet can consume fish, eggs, dairy dark leafy greens, nuts and seeds, as well as a number of vegetables, they also tend to eat all kinds of meat and poultry which is not pescatarian friendly. The trick to knowing what you can eat as a keto pescatarian is finding a middle ground that follows the rules of these two eating plans. Combining different diets for weight loss or healthier eating habits is not new, people have been doing it for many years now. While some diet combinations are quite easy to pull off, some such as the keto pescatarian diet can be quite the headache.

Health Benefits of the Pescatarian Keto Diet

The pescatarian keto diet may offer many benefits, but it requires the right strategies to work. Here are some benefits:

1. Blood Sugar Levels: The traditional pescatarian diet may lead to the consumption of carb-rich foods that can cause blood sugar spikes. The pescatarian keto diet can help you maintain blood sugar levels within an acceptable range. Keeping your blood sugar levels within an acceptable range helps avoid problems, especially if you’re at risk for prediabetes or already have diabetes. Studies have shown that a low-carb diet approach may lead to rapid improvements in glycemic control. Furthermore, it reduces insulin resistance to prevent the onset of diabetes. A 2021 narrative review also shows that limiting the intake of carbs prevents glucotoxicity or the impaired function of your beta cells, which are cells that secrete insulin. This is because carb restriction depletes glycogen stores, causing your body to burn its stored fat to produce ketones for fuel.
2. Nutrient Intake: Foods like fish, seafood, eggs, dairy, nuts, and seeds are high in fats and protein. Nuts, seeds, and low-carb veggies are also high in fiber. Following a pescatarian ketogenic diet can increase your nutrient intake.
3. Weight Loss and Management: The pescatarian ketogenic diet can aid in weight loss and weight management. It can reduce appetite and increase the body’s ability to burn fat. Low-carb diets have been known to suppress hunger better when compared to other traditional weight loss approaches. For example, 17 obese men in a crossover study not only lost more weight but also reported experiencing less hunger on a very low-carb diet. A study shows peak whole-body fat oxidation (or fat breakdown) is greater on a keto diet during exercise than other diets with varying macro ratios. Protein is an essential building block for the body’s tissues, and research suggests that consuming sufficient amounts of protein may aid in weight loss. Healthy Weight Loss: By inducing ketosis, this low-carb diet puts your body into fat-burning mode, aiding in weight loss.
4. Anti-Inflammatory Properties: The pescatarian keto diet is anti-inflammatory due to its high emphasis on fish and seafood, which are high in omega-3 fatty acids. Omega-3 fatty acids are polyunsaturated fats that may reduce inflammation, helping lower your risk of cancer, arthritis, and neurodegenerative diseases. They’re also noted for their cardiovascular benefits by lowering triglyceride levels and increasing HDL “good” cholesterol levels. In addition to fish and seafood, you can get your omega-3s from plant-based sources like walnuts, flax seeds, chia seeds, and Brussels sprouts. According to a review published in 2018, the American Heart Association advised that consuming a meal or two per week containing some type of seafood may reduce inflammation thanks to the omega-3s present in fatty fish. The same review that showed that this diet helps fight inflammation also stated that due to all the seafood consumed of such a meal plan, it may be helpful for reducing the risk of congestive heart failure, coronary heart disease, ischemic stroke, and sudden cardiac death.
5. Increased Fat Intake: The pescatarian keto diet can help you increase the intake of fats from fish and other products like olive oil.
6. Brain Function and Memory: The omega-3 fatty acids found in fish and seafood can boost brain function and memory.
7. Muscle Building: The keto pescatarian diet provides significantly more sources of protein compared to a vegetarian diet. Therefore, it can help you build muscle while reducing body fat through body composition. Since the low-carb pescatarian diet has more protein sources than a vegetarian diet alone, you can work on gaining muscle mass while losing body fat.

What Can Pescatarian Keto Eaters Eat?

Following a pescatarian keto meat plan involves the selection of foods that are both low in carbs and rich in healthy fats. The following food list is intended to help you simply navigate this meal plan by helping you identify what you can consume on this weight loss eating plan. The major components of the pescatarian keto diet include:

• Fish: Salmon, tuna, anchovies, sardines, Atlantic or Atka mackerel, cod, trout, catfish, herring, and pollock. Keep in mind that larger and older fish are typically high in mercury. Examples include king mackerel, golden bass, golden snapper, canned light tuna, swordfish, and shark.
• Shellfish: Shrimp, Scallops, Oysters
• Eggs: Whole eggs, preferably free-range
• Dairy: Cheese, Greek yogurt, heavy cream. As previously stated, most pescatarians consume dairy and eggs as part of this meal plan. However, a small percentage of them prefer to follow the diet while excluding these two protein sources.
• Nuts and seeds: Walnuts, pecans, almonds, Brazil nuts, hazelnuts, chia seeds, flaxseeds, sesame seeds, hemp seeds, and sunflower seeds. While nuts and seeds tend to be high in carbs, their net carbs are generally low. Thus they can be highly beneficial in moderate doses.
• Low-carb vegetables: Spinach, Zucchini, Cauliflower
• Healthy fats: Olive oil, avocado, nuts

These foods provide essential nutrients while keeping carb intake minimal.

Potential Challenges and How to Overcome Them

Following a pescatarian keto diet consistently can be challenging.

1. Carb Cravings: Keto diets can be tough at the very beginning, as it is more common to experience carb cravings.
2. Meal Planning: Meal planning can be stressful, regardless if you do it last minute or in advance. A keto app can help you not only select a variety of delicious and nutrient-dense keto recipes but also ensure that you don’t exceed your daily intake of carbs. Having a pre-established keto pescatarian meal plan will ensure that all your meals are keto-friendly and pescatarian. If you know that you will go without food for long periods of time, you may benefit from having your keto meals prepared in advance. Alternatively, you can opt for meals that don’t require lots of preparation time. Planning your meals in advance will also help you ensure that you are getting a wide range of micronutrients and avoid developing nutritional deficiencies.
3. Fat Sources: On a ketogenic diet, most of your calories should come from fats. Therefore, ensure that you have a variety of fat sources readily available.
4. Fruits and Vegetables: It’s crucial to consume a variety of fruits and vegetables on a keto diet, as they are valuable sources of vitamins, minerals, and fiber.
5. Hidden Carbs: Processed foods like chips, cookies, other snacks, and salad dressings often contain hidden carbs and unhealthy fats that can derail your keto diet.
6. Sweeteners: Sweeteners like sugar and honey are high in carbohydrates. So, it’s best to avoid them if you follow a keto lifestyle.
7. Hydration: Drinking plenty of water is essential on a pescatarian keto diet. In addition to water, you can also drink sparkling water, unsweetened herbal tea, unsweetened coffee, and other sugar-free beverages. Keep in mind that fruit juices and coconut water are high in carbs.
8. Tracking Macros: To ensure you are staying within your daily carb and protein limits, track your macros using a food diary or app. It allows you to select meals for which calories, as well as carb, protein, and fat ratios, have been calculated before.
9. Variety: There are many delicious and creative ways to prepare pescatarian keto meals. Experiment by cooking ingredients in different ways. For instance, you can eat boiled, fried, or baked eggs or add fried, grilled, baked, or smoked salmon to your meals. In addition, you can also swap ingredients that are high in carbs with ones that have a lower content of carbs. For example, instead of whole grains, you can opt for low-carb plant-based foods.

Tips for Success

The pescatarian keto diet may offer many benefits, but it requires the right strategies to work. To succeed on the Pescatarian Keto Diet, focus on a macro-balanced pescatarian meal plan, stay hydrated, and be consistent.

• Meal planning: Meal planning helps you save time and makes it easier to stick to your diet. Start small: There’s no need to plan a whole month’s worth of meals. Include quick-cook meals: You may have unexpected busy days. Explore 5-ingredient, easy recipes that can be ready in 15 minutes. Prepare your veggies and fruits: Washing, peeling, and chopping in advance will reduce meal prep time. Vary your menu: A varied menu gives a more enjoyable experience. It helps to categorize your shopping list based on grocery aisles.
• Separate Storage: If you live with other people who are not on this plan, consider having separate storage for your specific foods.
• Macro Ratios: The pescatarian keto diet follows the typical keto macronutrient ratio of 70-80% fat, 20-30% protein, and 5% or lower carbs. Macros, short for macronutrients, consist of three primary components: carbohydrates, proteins, and fats. The maximum number of carbs is 50, however many will restrict their carb intake between 20-30.
• Hydration: If this is your first time trying a low-carb pescatarian diet, you might experience electrolyte imbalances from water weight loss. Glycogen, the storage form of carbs, is stored with water molecules in your muscles. When glycogen is broken down, water is excreted through urine, and you lose electrolytes such as sodium and potassium.

Potential Risks and Considerations

1. Mercury Levels: Fish is one of the primary protein sources in this diet, and many types of fish contain mercury that isn’t good to consume in excess.
2. Nutrient Deficiencies: As MedlinePlus notes, vegetarians are already at risk of being deficient in vitamin B12, vitamin D, zinc, iron, calcium, omega-3 fatty acids, and protein. Keto then puts more restrictions in place, further increasing the likelihood of being deficient in some of these.
3. Cost: Pescetarian eating can be costly if you buy only fresh fruits, veggies, and fish.
4. Pregnancy: IMPORTANT: If you’re pregnant, breastfeeding, or considering becoming pregnant, it would be best to avoid eating raw or undercooked fish. This reduces your risk of exposure to potentially harmful bacteria that could affect you and your baby.
5. Restrictive: But for vegetarians who already rely on fiber-rich carbs like quinoa and oats - which are limited on the keto diet - to help them feel full, adopting low-carb keto might be overly restrictive.
6. Not for everyone: The Mediterranean diet is a healthier choice than the pescatarian diet. It offers a wider variety of foods that deliver nutrients not found in a pescatarian diet.
