Just Because You Could Live on Only Potatoes Doesn’t Mean You Have to, Scientists Say

Self-experimentation occurs in many fields, including nutrition and diets. One surprising example involves individuals who have tried a diet entirely based on potatoes. While the results they report are generally positive, engaging in this kind of self-experimentation may not be the best idea.

Potato diet. A wide variety of extreme diets has gained attention in recent years. One example is the potato-based diet. This approach involves subsisting mainly on potatoes (around 1 to 2.5 kg per day) for a short period, typically between three and five days. Some variations of this diet may incorporate additional foods.

Although this diet may seem like a contemporary fad or an overblown meme, historical accounts show its origins date back to at least the 19th century. One of its earliest proponents was British writer Lord Byron.

What does science say? Studying the effects of this type of diet can be complicated due to the associated risks. Focusing your diet on a single food item may help you control your calorie intake and facilitate weight loss. However, no single food provides enough variety of nutrients to ensure your bodies receive an adequate supply of both micronutrients and macronutrients.

This is particularly true for potatoes. Their caloric density has made them a staple food in South America, where they originate, as well as in other parts of the world. However, some nutrition experts have recently considered potatoes to be an inferior source of carbohydrates, a viewpoint that is certainly open to debate.

Some studies conducted with animal models have provided clues that may support the idea that potatoes can aid in weight management. One specific compound found in potatoes, known as proteinase II inhibitor, may play a role in this relationship.

Does it work? At first glance, it can be challenging to differentiate between a “miracle diet” and one that is scientifically proven and supported by research. Just because one person has had a positive experience with a particular diet doesn’t necessarily mean it’s healthy or effective for everyone.

The effects of dietary changes may not be immediately noticeable and can take time to manifest. While you might perceive some improvements, your body could be experiencing consequences that aren’t immediately obvious. Additionally, a diet that works well for one person may not meet your individual needs, which can vary significantly based on your unique circumstances.
