What Is The Potato Diet?

The potato diet is a short-term restrictive diet that is claimed to promote rapid weight loss. The idea of an all-potato diet was first introduced in 1849, but Tim Steele’s 2016 book ‘Potato Hack: Weight Loss Simplified’ revived it. Potatoes are the main source of calories in this diet. This popular fad diet is said to help you lose 0.45 kg weight by consuming potatoes while avoiding all other foods for three to five days. Though most people claim that this diet has helped them lose weight and strengthen their immune system, there is no scientific evidence to prove those claims.

The potato diet is specifically designed for weight loss. While there is not enough studies done on the potato diet, research shows that diets that restrict calories may help you lose weight (1). One study published in the Endocrinology and Metabolism Clinics of North America journal found that lower fat and calorie intake was linked with weight loss (2). People who follow the potato diet only eat 2-5 pounds of potatoes per day, which is around 530-1300 calories. This is less than the average adult intake, which is generally around 2000 calories a day for women and 2500 calories for men (3).
