In a landmark 1944 study involving 36 healthy men, one big finding from the Ancel Keys Minnesota Hunger Experiment was that semi-starvation causes severe psychological and behavioral changes, including depression and intense food obsession. The study revealed that these mental impacts were just as debilitating as the physical ones. The research, originally conducted to aid post-war famine relief, became a cornerstone for understanding the interconnectedness of physical and mental health.

In 1961, physiologist Ancel Keys appeared on the cover of Time magazine, an indication of his significant influence on American and global dietary habits. So, what did Ancel Keys do that led to such recognition, and why does his legacy remain a topic of debate in the scientific community today? His work covered diverse fields from military rations to large-scale epidemiological studies on heart disease.

The Mediterranean diet is based on the traditional eating patterns found in countries like Greece and Southern Italy during the mid-20th century. Its name originates not from a marketing gimmick, but from the groundbreaking scientific work of American biologist Ancel Keys, who studied the remarkable health and longevity of these populations.

First documented by American researcher Ancel Keys in the mid-20th century, the term *Mediterranean diet* was coined to describe the traditional eating patterns he observed in Southern Europe. This was based on the strikingly low rates of heart disease among populations in countries like Italy and Greece.

In 2010, the Mediterranean diet was recognized by UNESCO as an Intangible Cultural Heritage of Humanity, but its modern popularity stems from research in the 1950s led by American physiologist Ancel Keys. Keys is widely considered the founder of the modern concept, though the eating patterns he studied had existed for millennia.

In the mid-20th century, researchers like Ancel Keys observed that people in Crete and Southern Italy enjoyed remarkably low rates of chronic diseases and high life expectancy, a phenomenon linked to their traditional eating patterns. The true authentic Mediterranean diet is not a generic, modern trend but a specific, culturally rich foodway based on historical evidence from that period.

Between 1944 and 1945, participants in the Minnesota Starvation Experiment lost an average of 25% of their body weight, but the physical and psychological toll extended far beyond simple weight loss. The study's results profoundly reshaped the scientific understanding of semi-starvation and its devastating consequences on the human body and mind.

In the mid-20th century, following a severe decrease in coronary heart disease during World War II, physiologist Ancel Keys began investigating the link between diet and heart health. It was this curiosity that ultimately led to Keys and his wife, Margaret, introducing the Mediterranean diet as a concept to the world, though the eating pattern itself is thousands of years old.

In the 1950s, American physiologist Ancel Keys observed a significantly lower incidence of heart disease in post-war populations of Southern Italy compared to affluent Americans, sparking an investigation into the role of diet in cardiovascular health. This surprising finding set the stage for what would become the renowned Mediterranean diet concept.

During the mid-20th century, researchers observed that rural populations in Crete had exceptionally low rates of heart disease, prompting American scientist Ancel Keys to conduct the landmark Seven Countries Study and define what is the original Mediterranean diet.
