All About Keto-Friendly Eating
What is the Ketogenic Diet?
The ketogenic diet, or keto diet, is a low-carb, high-fat diet that has skyrocketed in popularity in recent years. Its history dates back to 1923 when it was first used as a treatment for epilepsy in children. The diet was prescribed by a physician, and patients were carefully monitored by a dietitian to ensure that they followed a very specific “macronutrient ratio” of 70% fat, 20% protein, and 10% carbohydrates.
Today, the keto diet is commonly used for weight loss. While modifications exist with slightly tweaked macronutrient ratios, the diet’s high-fat, moderate protein, low-carb core remains the same. Recommendations typically involve eating 65%-90% fat, 15%-30% protein and less than 10% carbohydrates per day.
How the Keto Diet Works
Eating a high-fat, moderate protein, low-carb diet encourages the body to convert fatty acids into ketones in the liver. Elevated levels of ketones in the blood trigger a metabolic state known as ketosis. When the body is in ketosis, it burns fat instead of carbohydrates for energy, resulting in weight loss.
The only way to really determine if you’re in ketosis is to measure ketone levels by taking a blood, urine or breath test - all of which can be done at home (test prices vary). Note that some people will require higher percentages of fat to trigger ketosis; others can achieve ketosis with a 65% fat diet. It’s advised to consult with a Registered Dietitian and/or healthcare provider for personalized nutrition recommendations.
Did you know that one sign of ketosis is bad breath? This is because ketones leave the body through breath and urine. Tip: Be sure to brush your teeth often and keep sugar-free mints or gum on hand. Some keto followers also report reduced appetite, increased mental clarity, increased energy and weight loss.
Getting Started on the Keto Diet
First, you’ll need to determine the macronutrient ratio that’s right for you. Keep in mind that it’s always a good idea to speak to a Registered Dietitian or your healthcare provider before starting any diet. Books, websites and apps are available for guidance and can help you plan and track your diet when you’re ready to begin. Be sure that the information is coming from a reliable source. Schedule an appointment with one of our registered dietitians.
Great news: Low-carb veggies, including leafy greens, lettuce, celery, mushrooms and zucchini, are allowed on the keto diet. Starchy plant-based foods such as corn, beans and potatoes may need to be limited.
Since the majority of the calories in this diet come from fat, it is important to choose a variety of different fats! Select unsaturated fats like olive oil, avocado oil, nuts, and seeds more often and saturated fats like coconut oil, butter, and heavy whipping cream less often.
For protein, choose high-quality meats such as wild salmon, free-range chicken, eggs, and grass-fed beef. Limit processed meats, such as cured bacon or deli slices, that may contain added sugar.
Minimize the amount of processed and carb-heavy foods such breads, pastas, fruit juices, rice and beer.
Luckily, snack ideas are just about endless for keto dieters. Feel free to graze on low-carb cheese sticks, hard-boiled eggs, olives, avocados, roasted almonds, walnuts, and sunflower seeds. Mixing chia seeds with unsweetened almond milk to create “chia seed pudding” is another great Keto-friendly snack idea! And for drinks, try adding coconut oil to your coffee or tea.
Need a keto diet-friendly lunch in a hurry? Try a BLAT (bacon, lettuce, avocado, tomato) wrap. Simply layer bacon, sliced avocado, sliced tomato, olive oil mayo and black pepper on romaine lettuce – then roll and eat. You can replace the bacon with canned Yellowfin tuna in olive oil for another variation. For dinner, toss some spiralized, steamed veggie noodles (zucchini noodles, aka zoodles, are great) with olive oil, sea salt and a squeeze of fresh lemon. Top with a grilled salmon fillet or grilled shrimp, toasted sesame seeds and a dash of black pepper.
Safety Considerations for Keto Dieters
Choosing more saturated fats over unsaturated fats could increase risk for heart disease and other health concerns. Cholesterol levels may need to be checked often to monitor heart health. Talk to your healthcare provider about additional health screenings. Discuss your diet plans with your Registered Dietitian and/or healthcare provider.
