Triathlete doctor shares eating habits that keep him fit at 83

An 83-year-old doctor, Joseph Maroon, who is a triathlete and a neurosurgeon at the University of Pittsburgh Medical Center, shared his diet principles that have helped him lead a long, healthy life.

"I was out of shape, living on fast food and not exercising," he wrote on his website.

At the age of 40, Dr Maroon managed to transform his lifestyle, thanks to running and a healthier diet.

He has since completed eight Ironman Triathlons and secured second place in his age category for the 2022 National Senior Games triathlon. A triathlon is an athletic contest consisting of three different events, typically swimming, cycling, and long-distance running. It is one of the most intensely physical competitions.

He revealed that he follows four basic eating habits for a healthier life.

Mediterranean Diet

Dr Maroon told Business Insider that follows the Mediterranean diet, which has been recognised as the best eating plan by the US News & World Report for seven years.

This diet emphasises plant-based foods, whole grains, and healthy fats, with occasional intakes of fatty fish and red meat.

This diet has been associated with a lower risk of heart disease, cancer, and Alzheimer's disease.

Avoid ultra-processed foods

The neurosurgeon advised avoiding ultra-processed foods (UPFs) and trans fats, which have been linked to an increased risk of illnesses like cancer, dementia, and cardiovascular disease. Foods like protein bars, hot dogs, packaged foods should be avoided.

Avoid trans fatty acids

Trans fats are associated with high levels "bad" cholesterol in the body. These fats can increase the risk of heart disease and stroke.

Limit sugar intake

Dr Maroon also suggested limiting sugar intake as it can lead to an increased risk of diabetes, cardiovascular disease, chronic kidney disease, and Alzheimer's disease.
