Organ meats are the dark horse in the quest for optimal performance. Though often overlooked or even shunned, they offer a wealth of health benefits even the trendiest superfoods and supplements can't match.
But somewhere along the way, traditionally consumed organ meats became second-best to muscle meat — despite their superior nutritional value. That ends today.
We’re exploring why these nutrient-dense delicacies deserve a place in your ketogenic diet. You’ll also discover our favorite ways to add more organ meats to your game plan.
Organ meats (offal) refer to an animal’s edible internal organs. While hunters have access to the organs of game meat, the general population snags them from cows, pigs, chickens, ducks, lambs, and goats. The most commonly consumed types of organ meat include:
If the thought of consuming these makes you squirm, the nutrient density of organ meats might change your mind.
Organ meats are the most nutrient-dense foods we can eat. They’re a powerhouse of every essential amino acid and omega-3 fatty acids. These meaty multivitamins are also high in essential vitamins, minerals, and micronutrients necessary for optimal health and performance.
Eating organ meats just makes sense on a keto diet. These rich protein sources help you grab more bioavailable nutrients than you can get from most fruits and veggies — without the carbs (or blood sugar spikes!).
So, to highlight all the incredible benefits of organ meats, let’s compare nutrient concentrations in high-quality organ meats with those found in more popular “superfoods,” starting with:
Antioxidant-rich vitamin A is pivotal to your vision health and immune function.[*] It’s typically found in foods like sweet potatoes, carrots, cantaloupe, etc., which are too high in carbs for a keto diet.
Luckily, beef liver is the richest source of vitamin A on the planet. This fat-soluble vitamin must be consumed with fat for your body to absorb it (like vitamin D), making organ meat an ideal two-for-one source.[*]

This vitamin is a key component of coenzymes involved with energy production, cell function, and the breakdown of fats.[*] Most people get B2 from fortified cereals, oats, and milk, which are a no-go on a keto diet.

B12 is an essential vitamin required to maintain healthy nerves and produce neurotransmitters such as dopamine and serotonin. These regulate mood, sleep, and cognitive function.[*][*]
B12 only occurs naturally in animal foods, so you must supplement it on a vegetarian or vegan keto diet. Organ meats are an incredible source of B12:

Choline is an essential nutrient our nervous system needs (including our brain and spinal cord). It regulates memory, mood, and muscle control and helps synthesize neurotransmitters.[*][*]
Organ meats are one of the richest sources of choline, which may explain why 90% of Americans aren’t getting enough.[*] This lack may be connected with a higher risk of Alzheimer’s disease.[*]

Iron is essential for making red blood cells, transporting oxygen throughout your body, producing energy, and powering your muscles. Heme iron (found in meat, poultry, and seafood) is more bioavailable than non-heme iron (found in plant foods).[*]
Thanks to menstrual cycles, women need twice as much iron as men.[*] Luckily, organ meats provide a rich source of this mineral:

Coenzyme Q10 is a powerful antioxidant that protects your cells and may reduce your risks of cardiovascular disease.[*] Studies show it lowers inflammation and may be useful for combating Western diet-related health issues like metabolic syndrome, type 2 diabetes, neurodegenerative disorders, kidney disease, and infertility.[*]
There’s no recommended daily intake for CoQ10. However, organ meats (especially heart, liver, and kidney), red meat, pork, and poultry are good sources.
Organ meats are generally well tolerated. Unfortunately, you should speak with your healthcare provider about how much you consume if you have gout (a common form of arthritis). Offal contains purines, which can raise uric acid levels that cause or worsen gout.[*]
Adding organ meat to your diet is a simple yet powerful way to elevate your health and performance. Begin with these tips:
