THE HARVARD CARNIVORE DIET STUDY: FINDINGS AND TAKEAWAY By Liam McAuliffe Updated on December 19, 2023 Tags: Carnivore Diet, Carnivore Diet Foods In 2020 a team of researchers at Harvard University conducted the first mainstream study on the carnivore diet. The study surveyed over 2000 carnivore dieters. And the findings were published on 2 November 2021 in Current Developments in Nutrition. [1] The fact that such a renowned institution took this radical diet seriously is a testament to its rapidly growing popularity and the experiences of influential adopters. Podcaster Joe Rogan, psychologist Jordan Peterson, and popular doctors including Dr. Kiltz, Dr. Ken Berry, and Dr. Shawn Baker, all practice and promote the carnivore diet as a foundation of health and wellness. In this article, we’ll explore the details of who was involved, what they ate, key findings with regard to effects on health, and the conclusions drawn of the Harvard carnivore study researchers.

Based on the data, researchers concluded that “Contrary to common expectations, adults consuming a carnivore diet experienced few adverse effects and instead reported health benefits and high satisfaction.” [9] Here are some more findings SELF-REPORTED CHANGES IN HEALTH STATUS Source: Belinda S Lennerz, Jacob T Mey, Owen H Henn, David S Ludwig, Behavioral Characteristics and Self-Reported Health Status among 2029 Adults Consuming a “Carnivore Diet”, Current Developments in Nutrition, Volume 5, Issue 12, 2021, The self-reported changes in health status were overwhelmingly positive: * 95% improved overall health * 91% improved hunger/food cravings * 89% improved energy * 85% improved mental clarity * 83% improved focus * 78% improved strength * 76% improved endurance * 69% improved sleep * 69% improved chronic disease * 66% improved memory HOW CHRONIC CONDITIONS CHANGED * 98% improved or resolved diabetes and insulin resistance * 97% improved or resolved gastrointestinal conditions * 96% improved or resolved musculoskeletal issues * 96% improved or resolved psychiatric symptoms * 93% improved or resolved overweight/obesity (mean BMI decreased from 27.2 to 24.3) * 93% improved or resolved hypertension * 92% improved or resolved urologic issues * 92% improved or resolved dermatologic issues * 89% improved or resolved autoimmune conditions * 84% improved or resolved cardiovascular issues HOW MEDICATION USE CHANGED * 100% discontinued other diabetes injectables * 92% discontinued insulin for type 2 diabetes altogether * 90% discontinued or decreased insulin * 84% discontinued oral diabetes medications. LEVEL OF SATISFACTION WITH THE CARNIVORE DIET * 98% of participants reported being very satisfied or satisfied STUDY LIMITATIONS This study was based on self-reported responses to an online survey. Recalling what exactly one eats in a week, month or year is notoriously difficult. And there is no way to objectively verify the accuracy of self-reported eating habits and health outcomes. THE TAKEAWAY FROM THE HARVARD CARNIVORE STUDY In the context of a grain-based society where meat is demonized and plant foods are lauded as the key to health, the idea that eating an all-meat diet is healthy, let alone possible, seems radical. However, numerous studies show that high-fat, low-carb animal-based diets are how our ancestors evolved eating over nearly 2 million years.3 For these reasons, it’s important that a reputable and notable institution like Harvard take the carnivore diet seriously. Though the outcomes of the Harvard carnivore study likely come as no surprise to carnivore dieters, the overwhelmingly positive responses should compel further studies that will corroborate these reports and elevate the carnivore diet further into mainstream consciousness.
