The Foundation: Quality Foods for Optimal Ketosis
The foundation of a successful ketogenic diet begins with understanding which foods to eat. Rather than simply focusing on "low-carb" options, the Keto+ approach emphasizes optimizing nutrition through nutrient-dense food choices. This means selecting not just any low-carb foods, but the right ones that maximize health benefits.
"You are literally what you eat"-your cells, hormones, gut microbiome, muscles, blood vessels, and nerves all depend on the quality of your nutritional intake. While both "dirty keto" (focusing solely on macros without regard for food quality) and Keto+ can produce short-term benefits, long-term health outcomes will differ dramatically based on food quality.
The Keto+ approach recommends focusing on nutrient-dense, high-quality foods rather than simply anything low-carb. Recommended foods include quality protein sources (grass-fed beef, pasture-raised chicken, wild-caught fish, eggs), healthy fats (avocados, olive oil, coconut oil, grass-fed butter, ghee), low-carb vegetables (leafy greens, cruciferous vegetables, zucchini), limited low-sugar fruits (berries), and select nuts and seeds.
The quality of meat on a ketogenic diet is crucial for optimal health. The sourcing of meat matters tremendously-grass-fed and organic options provide better omega-3 to omega-6 ratios, more nutrients, and fewer toxins than conventional options. For example, grass-fed beef contains more conjugated linoleic acid (CLA), beta-carotene, and fat-soluble vitamins than grain-fed counterparts.
Organ meats, though often overlooked in modern diets, are the most nutrient-dense foods available-far more so than vegetables like kale. Their nutrients are highly bioavailable, making them nature's multivitamin. Traditionally consumed by our grandparents out of necessity, organs from cows, pigs, lambs, goats, chickens, and ducks provide exceptional nutrition on a ketogenic diet.
Seafood provides essential omega-3 fats (EPA and DHA) that combat inflammation and support brain development. These healthy fats help maintain an appropriate omega-6 to omega-3 ratio, which is crucial when consuming red meat that may contain higher omega-6 levels. Beyond omega-3s, seafood offers valuable antioxidants like astaxanthin that protect the brain, plus important micronutrients including magnesium, potassium, selenium, zinc, and B vitamins.
For cooking oils, the best options for keto are coconut oil, MCT oil, palm oil, avocado oil, macadamia nut oil, and olive oil. These have beneficial fatty acid profiles that support healthy metabolism. However, proper handling is crucial-never heat oils beyond their smoke point, as this creates oxidized, health-damaging fats.
Beyond avoiding high-carb foods (generally those with more than 5g net carbs), the Keto+ approach recommends limiting or avoiding several seemingly keto-friendly foods. Vegetable oils (sunflower, canola, corn, peanut, safflower, soybean, and partially hydrogenated oils) are extremely pro-inflammatory and should be strictly limited. Highly processed foods with long ingredient lists should be avoided, as should soy products, which contain potentially problematic phytoestrogens and commonly trigger negative reactions.
Whether dairy works on keto depends on your personal tolerance. Dairy contains lactose sugar which in high amounts can impact ketosis and overall health. Lower-carb dairy may work for some but not others, depending on your ability to tolerate either lactose (sugar) or casein (protein).
