The subtitle should be, “Or is it?” How many million tons of potatoes have been consumed over the centuries? Shouldn’t both facts and opinions have solidified by now? It appears not.

Of course, a lot of details are involved. Are red potatoes nutritionally superior to white ones? What about the disagreement over whether sweet potatoes and yams should be permitted to join the hallowed ranks?

The role of potatoes in improving or demolishing a person’s weight status has long been debated. In 2014, a 90-subject study “sought to gain a better understanding of the role of calorie reduction and the glycemic index in weight loss when potatoes are included in the diet.”

Funded by none other than the United States Potato Board, the study determined that “People can eat potatoes and still lose weight.” Lead investigator Dr. Britt Burton-Freeman, Ph.D., stated,

[…] the results of this study confirm what health professionals and nutrition experts have said for years: it is not about eliminating a certain food or food groups, rather, it is reducing calories that count.

Only two years later, author Tim Steele published a book called Potato Hack, which revived an idea that that been introduced way back in 1849 — the notion that people could thrive and stay slim on a diet consisting solely of potatoes. Journalist Makayla Meixner explained,

Though many variations exist, the most basic version claims to help you lose up to one pound (0.45 kg) a day by eating nothing but plain potatoes.

Many impressive claims were made, including strengthening of the immune system, improved gut health, and definitely enough nutrition to keep a person energized. Although the potatoes-only diet was meant to be followed for three, or at most five, days at a time, of course, some zealots went overboard with the notion.

Celebrity endorsement

Professional magician Penn Jillette climbed aboard the bandwagon, and began his monumental weight-loss effort with two weeks of nothing but potatoes, during which he shed 18 pounds. Later, after more work, he published a book called Presto!: How I Made Over 100 Pounds Disappear.

Do spuds contain any good stuff? You bet! There’s Vitamin C, potassium, folate, iron, and a ton of fiber, all for a pretty cheap price. But the tuber is low in calcium, Vitamin A, B vitamins, and other nutrients. Potatoes do contain something called proteinase inhibitor 2 that is suspected of slowing digestion and thus decreasing hunger. Another authority, however, considers slowed metabolism to be a negative outcome.

With such a lack of essential ingredients, an all-potato regime would certainly not be a good long-term solution. Also, as with any extremely low-calorie diet, there would be not only a decrease in fat but in muscle mass, which could be harmful. In addition, if the person returns to a more normal diet, the weight will probably come back.

A 2016 paper published in the American Journal of Clinical Nutrition

[…] included a systematic review of 13 different studies on the effect potatoes have on weight as well as some chronic diseases. The researchers determined that there’s not enough evidence to suggest that eating potatoes leads to weight gain.

Are potatoes generally good or bad for weight loss? The issue is contentious. One online commentator wrote, “I wish academics would stay out of conflicted situations like this one.” But then, who else would be doing the scientific research?
