James O'Keefe Jr. (born June 8, 1956) is an American author and cardiologist who has conducted studies in the field of cardiovascular medicine, diet and exercise. O'Keefe is a leading proponent of exercise but argues that moderate rather than extreme efforts, in a social setting-like are best for conferring longevity. He has also proposed a hypothesis regarding the evolutionary basis of homosexuality. He is currently a professor of medicine at the University of Missouri–Kansas City, Director of Preventive Cardiology at the Mid America Heart Institute of Saint Luke's hospital and Chief Medical Officer of the health supplement company Cardiotabs.
James Henry O'Keefe Jr. was born to James Henry O'Keefe Sr. and Leatrice O’Keefe in Grand Forks, North Dakota, on June 8, 1956. He graduated from the University of North Dakota where he received an undergraduate BS summa cum laude and Phi Beta Kappa in Natural Science. In 1982, he received his MD summa cum laude with his MD from Baylor College of Medicine. He was a member of Alpha Omega Alpha.
O'Keefe completed his medical residency as well as a CV fellowship at the Mayo Graduate School of Medicine in Rochester, Minnesota.
At the Mid America Heart Institute, he was involved with patient care, clinical research as well as non-invasive cardiology practices. He has been board-certified in cardiology, nuclear cardiology, pacemakers, cholesterol management, cardiac CT imaging, and internal medicine.
O'Keefe has contributed over 358 articles to peer-reviewed medical literature. These include his studies on the potential dangers of excessive exercise, the evolutionary basis of homosexuality, and that sugar not salt is the evil white crystal that needs to be eliminated from our diets. O'Keefe also focuses on improving sleep, post-meal spikes in blood sugar, and fatty liver to improve health and well-being. He has been the lead author of several books, including, the Complete Guide to ECGs, The Forever Young Diet & Lifestyle and Let Me Tell You a Story.
O'Keefe believes that a healthy lifestyle should include some features of the diet and activity patterns of our ancient ancestors. He argues that this is essential because our nutritional needs were established many centuries ago in the remote pre-historic past; thus humans have been genetically adapted to thrive in a Hunter-Gatherer type of lifestyle. O’Keefe believes this mismatch between the diet and lifestyle for which we are genetically adapted, and the very different conditions in which we are living, is the underlying cause for much disease, disability and unhappiness. Our ancestors survived on a diet high in fish, nuts, fruits, vegetables, wild game meat and bones. They also received a large amount of exercise from walking, bending, lifting, carrying, swimming, climbing, and other activities that were necessary to their daily routines. O’Keefe recommends beverages including water, sparkling water, green tea and coffee; also, red wine can be a healthy choice if used in moderation.
Evolutionary basis of homosexuality
O’Keefe gave a TEDx Talk in October 2016, on the natural origin of homosexuality. In this talk, and subsequent scientific paper, he proposes a theory about the evolutionary basis of homosexuality mediated by epigenetics. This theory posits that homosexuality is a naturally intended, normal variant that evolved to improve the interconnectedness and resilience of the family. The suite of psychological traits that tend to co-occur with same-sex orientation include increased IQ, and higher emotional intelligence, with less physical aggression. Through a complex interplay of epigenetics and genetics, homosexuality occurs more often in larger families, especially in a baby boy with multiple older brothers, or at times of increased stress during the pregnancy. In these settings, homosexuality is prescribed by nature largely via epigenetic changes in the developing fetus in response to the mother's environment. This can help to reduce overpopulation pressures at the family level; the gay individual also tends to improve the emotional bonding of their family and friends, thereby improving the strength survivability of the group.
O'Keefe's research and publications have focused mostly on exercise, diet and evolution. Daily exercise is one of the key components of lifestyle for promoting health and longevity, and will reduce risks for heart disease, Alzheimer's, hypertension, osteoporosis, depression and diabetes dramatically. However, excessive endurance exercise may potentially cause CV damage. This work has garnered attention in both the cardiology world and the general public. The articles suggest that extreme endurance exercise such as marathons, ironman distance triathlons, and long distance bicycle races may, over many years to decades, in some individuals lead to adverse structural changes in the heart and large arteries, predisposing to "cardiac overuse injury." CV damage can include fibrosis (scarring) in the heart muscle, accelerated plaque buildup in coronary arteries and atrial fibrillation. These papers emphasize that exercise best confers benefits to longevity and cardiac health at moderate doses. O'Keefe discusses this in a TEDx Talk entitled: "Run for your life! At a comfortable pace and not too far."
O'Keefe has published papers on the CV impact of both coffee and alcohol showing evidence that supports moderate consumption of either or both substances can be potentially heart healthy. Habitual light to moderate alcohol intake (up to 1 drink per day for women and 1 or 2 drinks per day for men) is associated with decreased risks for total mortality, coronary artery disease, diabetes mellitus, congestive heart failure, and stroke. However, higher levels of alcohol consumption are associated with increased CV risk. Coffee consumption may reduce the risk of CV death, type 2 diabetes mellitus, suicide and Parkinson's disease.
In 2018, he published an article about an evidence-based approach to the ideal diet for health and longevity.
In 2016, he published a paper entitled Nutritional strategies for skeletal and cardiovascular health: hard bones, soft arteries, rather than vice versa. This paper showed that calcium is ideally obtained from dietary sources. The form of calcium in bones and bone meal is calcium-hydroxyapatite, which may be particularly effective for building bone. Increased consumption of calcium-rich foods such as bones, fermented dairy products (e.g. yogurt, kefir, cheese), leafy greens, almonds, and chia seeds may be effective for improving both skeletal and CV health.
O'Keefe has a family legacy in the medicine profession. His great grandfather, Henry O'Keefe, practiced medicine in North Dakota from 1890 to 1935. Henry's son, Emmett (James' grandfather), was also a doctor in North Dakota.
O'Keefe met his wife, Joan, while at the Mayo Clinic. The two married in October 1984 and together they have four children: James III, Evan, Kathleen, and Caroline. Evan started medical school in January 2016.
