Exploring the Keto Lifestyle: 20 Foods to Fuel Your Journey
Demystifying the Ketogenic Diet: Benefits Beyond Weight Loss
The ketogenic diet has become a popular trend, but what exactly is it? In this blog, we'll explore the science behind this low-carb, high-fat approach. We'll look at its history of treating epilepsy and its potential benefits for managing weight, diabetes, and even certain cancers. Additionally, we'll explore how ketosis, the metabolic state achieved through this diet, may impact the brain and body in neurodegenerative diseases. Join us as we separate fact from fad and unveil the potential of the ketogenic diet.
Eating high fat low carb foods is the principal of a Keto diet. Followers of this diet may consume a variety of animal proteins, dairy, vegetables, other plant-based foods, and fats and oils.
The ketogenic diet’s increasing popularity is largely due to its potential benefits for weight loss and blood sugar control. Early evidence also suggests that this low carb, high fat diet may help treat certain cancers, Alzheimer’s disease, and other health conditions. Still, higher quality research is still needed to determine the keto diet’s long-term safety and effectiveness.
The keto diet typically limits carbs to 20–50 grams per day. While some people on keto count their total carb intake, others count net carbs. Net carbs refer to total carbs minus fiber. That’s because fiber is indigestible, so it can’t be broken down and absorbed by your body. This diet may seem challenging, but it allows people following it to eat many nutritious foods.

1. Seafood
Fish and shellfish can be a great addition to a ketogenic diet. Here's why:
-
Low in Carbs: Most fish and some shellfish are very low in carbs, making them a perfect fit for a keto diet. Salmon, for example, is nearly carb-free. (NDB)
-
Rich in Nutrients: Fish is packed with essential nutrients like B vitamins, potassium, and selenium, all beneficial for your health. (NDB)
Keep in Mind:
-
Shellfish Carbs: The carb content in shellfish can vary depending on the type. While shrimp and most crabs are carb-free, oysters and octopus contain some carbs. You can still enjoy them, but carefully track the carbs to stay within your keto macros. (NDB, NDB, NDB, NDB)
-
Omega-3 Benefits: Fatty fish like salmon, sardines, and mackerel are rich in omega-3 fats. Studies suggest these fats may help lower insulin levels and improve insulin sensitivity in overweight or obese individuals. (Reference)
-
Brain Health: Eating fish regularly may be linked to improved brain health and a reduced risk of certain diseases. (Reference, Reference)
Recommendation:
The American Heart Association recommends adults consume 8-10 ounces of seafood per week. (Source)

2. Meat and Poultry
Meat and poultry are major players on the keto scene, and for good reason. Here's what makes them keto-friendly:
-
Zero Carbs: Fresh meat and poultry are naturally carb-free, perfectly fitting a ketogenic diet.
-
Nutrient Powerhouse: Meat and poultry are rich in B vitamins and several essential minerals, needed for good health.
-
Protein for Muscle: They're also a fantastic source of high-quality protein, which can help preserve muscle mass during a very low-carb diet.
Potential Benefits:
- Good Cholesterol Boost: A small study in older women suggests a diet high in fatty meat may lead to increased levels of HDL (good) cholesterol compared to a low-fat, high-carb diet.
Grass-Fed Might Be Better:
Consider opting for grass-fed meat whenever possible. Studies suggest it may be higher in omega-3 fats and conjugated linoleic acid (CLA) compared to grain-fed options.

3. Eggs: A Ketogenic Powerhouse
Eggs are a breakfast staple, but they deserve a place on your keto plate any time of day. Here's why they're perfect for a ketogenic diet:
-
Low in Carbs and High in Protein: A single large egg boasts less than 1 gram of carbs and around 6 grams of protein, making it an ideal fit for keto macros.
-
Boosts Satiety: Eggs can help you feel fuller for longer. Studies suggest they trigger hormones that regulate satiety.
Whole Eggs are the Way to Go:
-
Nutrient-Rich Yolks: Choose whole eggs over just egg whites. The yolk is where most of the egg's nutrients reside, including lutein and zeaxanthin, antioxidants important for eye health.
-
Cholesterol Concerns: While egg yolks are high in cholesterol, research suggests they don't necessarily increase your risk of heart disease.
Remember: Most animal proteins, including eggs, beef, pork, poultry, and seafood, are generally low in carbs and suitable for the keto diet.

5. Cheese: A Ketogenic Delight
Cheese lovers rejoice! Most cheese varieties are keto-friendly thanks to their low carb and high-fat content.
- Carb Count and Macronutrients: A single ounce of cheddar cheese (around 28 grams) contains just 1 gram of carbs, 6 grams of protein, and a good amount of calcium, making it a perfect addition to your keto macros.
Beyond Carbs: Potential Health Benefits:
-
Saturated Fat and Heart Disease: Cheese is high in saturated fat, but research suggests it may not necessarily raise your risk of heart disease. Some studies even suggest it might be protective.
-
CLA and Body Composition: Cheese contains CLA (conjugated linoleic acid), which has been linked to fat loss and improvements in body composition.
-
Muscle Retention: Studies suggest that regularly eating cheese may help reduce muscle loss and weakness associated with aging. A 12-week study found older adults who consumed 7 ounces (210 grams) of ricotta cheese daily experienced less muscle loss compared to those who didn't.
Keto-Friendly Cheeses:
Here's a list of some generally lower-carb cheeses suitable for a keto diet:
- Blue cheese
- Brie

5. Plain Greek Yogurt and Cottage Cheese: Keto with Caution
Plain Greek yogurt and cottage cheese can be part of a keto diet, but with a note of caution. Here's why:
- High Protein, Some Carbs: Both are nutritious and rich in protein, a key nutrient on keto. However, they also contain some carbs.
Moderation is Key: To stay within your keto macros, it's important to enjoy them in moderation.
Potential Benefits:
- Appetite Control: Studies suggest that both yogurt and cottage cheese can help reduce appetite and promote feelings of fullness, which can be beneficial for weight management.
Keto-Friendly Snack Ideas:
- Enjoy plain Greek yogurt or cottage cheese on their own.
- For extra flavor and texture, add chopped nuts, cinnamon, or other keto-friendly spices.
Remember: Always check the nutrition label of your chosen yogurt or cottage cheese, as carb content can vary depending on the brand.

6. Cream and Half-and-Half: Keto-Friendly with a But
Cream and half-and-half can be part of a keto diet, but there are some things to consider:
- Low-Carb, High-Fat: Both cream and half-and-half are keto-friendly because they're low in carbs and high in fat.
Potential Fat Loss Benefits:
- Like other fatty dairy products, cream is rich in CLA, which may be linked to fat loss.
Moderation is Key:
- Saturated Fat and Heart Disease: The American Heart Association recommends limiting saturated fats like those found in cream and half-and-half. Replacing these fats with plant-based or polyunsaturated fats is linked to a lower risk of heart disease and stroke.
The Research on Dairy and Heart Disease:
- Conflicting Evidence: Research on the connection between high-fat dairy products like cream and heart disease is inconclusive. Some studies suggest minimal association, while others suggest a possible benefit for heart health in moderate intake.
Factors at Play:
- Processing Matters: The level of processing a food has undergone may impact its health effects. This is an ongoing area of research.
The Takeaway:
- Cream and half-and-half are popular additions to coffee or keto substitutes for small amounts of milk in cooking. While they fit the keto macros for carbs and fat, enjoy them in moderation due to the saturated fat content.

7. Unsweetened Plant-Based Milk: A Keto-Friendly Option for Some
While some plant-based milks can be incorporated into a keto diet, it's important to choose wisely:
-
Keto-Friendly Options: Unsweetened versions of soy milk, almond milk, and coconut milk can be suitable for keto due to their lower carb content.
-
Sweeteners are the Enemy: Avoid sweetened plant-based milk varieties as they typically contain high amounts of sugar, which are not keto-friendly.
-
Oat Milk is a No-Go: Even unsweetened oat milk is generally too high in carbs to fit comfortably into a keto diet.
Remember: Always check the nutrition label of your chosen plant-based milk, as carb content can vary slightly between brands.

Dark Green All-Stars: For an extra nutritional boost, choose dark leafy greens like spinach, kale, and collard greens. These are rich in vitamin K and iron.
