In 2010, Chris Voigt raised awareness of the nutritional value of potatoes by eating only potatoes for 60 days. Consuming 20 potatoes daily, he aimed for an intake of 1,600 to 2,200 calories, adding only small amounts of oil and seasoning without any supplements. After 60 days, Voigt, the executive director of the Washington State Potato Commission, had lost 9.5kg (21lbs), and his cholesterol and blood sugar levels had significantly improved. “I want to show… that the potato is so healthy that you could live off them alone for an extended period of time without any negative impact on your health,” Voigt stated.
Mark Taylor, the 52-year-old winner of the Mr. Universe Masters Over 45 title in 2023, also swears by a high-carbohydrate diet, including white and sweet potatoes and oat porridge. Previously on a high-protein diet that left him feeling fatigued, Taylor noticed more energy and muscle fullness after switching to whole carbohydrates. “People don’t believe they need carbs for bodybuilding, but this is the most successful I’ve ever been,” he said. Taylor now provides online coaching to help others achieve their fitness goals.
Carbohydrates often face criticism for allegedly causing weight gain and blood sugar spikes. However, studies show that whole and natural high-carbohydrate foods can reduce the risk of diseases. A 2022 study in Diabetes Care found that high vegetable consumption, including boiled potatoes, was linked to a 21% lower risk of developing type 2 diabetes. Similarly, a 2023 study in BMC Medicine connected high-fiber, whole grain carbohydrates with a lower risk of cardiovascular disease.
Dr. Soham Patel, an endocrinology specialist in Florida, emphasizes the importance of the type of carbohydrates consumed. Foods high in fiber generally have a lower glycemic index (GI), leading to slower digestion and more stable blood sugar levels. For example, eating a whole apple, which contains fiber, is preferable to drinking apple juice, which lacks fiber and can spike blood sugar levels.
Hong Kong-based dietitian Cyrus Luk highlights the benefits of fiber-rich foods such as sweet potatoes, pumpkin, brown rice, oats, and quinoa. These foods are low in fat and packed with essential vitamins and minerals. Luk advises minimizing refined and processed carbohydrates like potato chips and pastries, which are high in unhealthy fats.
Voigt, who still enjoys potatoes daily, has maintained his health and weight since his potato diet. He is considering another potato-only diet for an ambitious athletic challenge, dreaming of cycling across the United States powered solely by potatoes.
By understanding the nutritional benefits and incorporating whole carbohydrates into their diets, individuals can achieve better health and performance while enjoying versatile and nutritious foods like potatoes.
