There always seems to be a new diet circulating the health and wellness world, with some being fads and others being long-term commitments. As a nutritionist, I often encourage people to avoid diets and simply stick to whole foods and everything in moderation. However, should the potato diet be an exception?
Keep reading to find out what exactly the potato diet is, how it works, and its potential benefits and downsides!
What is the potato diet?
The potato diet is a short-term, elimination-style eating plan where you consume mostly potatoes for a set period, typically ranging from three days to two weeks. As the name suggests, this diet involves eating only plain, unprocessed potatoes without added fats, seasonings, or other foods. The idea is to simplify your diet drastically to reduce calorie intake and reset your eating habits.
According to UC Davis, “Potatoes contain vitamins, minerals, and fiber. They’re rich in vitamin C, which is an antioxidant.” These components make them surprisingly nutrient-dense despite their simplicity.
The potato diet gained popularity due to anecdotes of quick weight loss and appetite suppression. It is often used as a reset to help curb cravings and promote mindfulness around eating. However, because it is very restrictive, it’s considered a temporary approach rather than a sustainable long-term diet. People who follow it often report a mental and physical detox from highly processed foods, which may contribute to its appeal.
How do you follow the potato diet?
Following the potato diet is quite simple, and it involves eating primarily plain potatoes throughout the day. You can boil, bake, or steam them, and no butter, oil, or seasonings should be used. Some diet variations allow a small amount of salt, while stricter versions forbid even that.
You can eat as many potatoes as you want until you feel full, which helps avoid calorie counting and can prevent feelings of deprivation. It’s important to still drink plenty of water, and unsweetened tea or black coffee are also permitted. Avoid all other foods, including fruits, vegetables, proteins, and processed items, during the diet period.
Many people prepare potatoes in bulk to make the process easier and avoid temptation. After completing the diet, it’s essential to reintroduce foods gradually and mindfully to avoid digestive discomfort and maintain balanced nutrition. This slow transition also helps identify any food sensitivities or reactions that might have been masked before.
What are the benefits of the potato diet?
While this diet won’t end up being beneficial for most people, especially compared to a balanced diet that involves whole foods and portion control, you may experience the following perks.
Weight loss
Due to its low calorie density and fiber content, the potato diet can lead to rapid weight loss. Eating mostly potatoes keeps you full longer and reduces your overall calorie intake naturally, without counting calories. This can be especially useful for those who struggle with portion control or emotional eating.
Appetite control
Potatoes contain resistant starch and fiber, which slow digestion and promote feelings of fullness, helping to reduce overeating and curb cravings. This natural appetite suppression can make it easier to stick to the diet and avoid snacking on unhealthy foods.
Nutrient simplicity
The diet’s simplicity may help those overwhelmed by complex diet choices reset eating habits, reducing processed food intake and encouraging mindful eating. It removes decision fatigue around meals, which can be empowering for some.
Digestive health
The fiber in potatoes supports healthy digestion and regular bowel movements, which may improve gut health during the diet. Resistant starch acts as a prebiotic, feeding beneficial gut bacteria and potentially improving microbiome diversity.
Does the potato diet have any downsides?
Nutritional deficiencies
Eating only potatoes lacks variety and omits essential nutrients like protein, healthy fats, and certain vitamins and minerals, which can lead to deficiencies if followed too long. A lack of protein can also impair immune function and muscle repair.
Sustainability issues
The restrictive nature makes it difficult to maintain long-term, and many may find it boring or socially isolating. Such a limited diet can also cause cravings and a tendency to binge once the diet ends.
Potential muscle loss
Without adequate protein intake, prolonged adherence might cause muscle breakdown, negatively impacting metabolism and strength. This can undermine fitness goals and long-term health.
Blood sugar fluctuations
Although potatoes have fiber, their high carbohydrate content can cause blood sugar spikes in some people, which may be problematic for those with insulin resistance or diabetes. Monitoring blood sugar and portion sizes is important for these individuals.
Frequently asked questions
How much weight did Kevin Smith lose on the potato diet?
Kevin Smith reportedly lost 17 pounds in just nine days by following the strict potato mono diet post–heart attack.
Does the potato hack actually work?
The potato hack can work for short-term weight loss due to its simplicity, low calorie density, and appetite-suppressing effects, and many people do report losing weight quickly. However, it’s not a balanced long-term solution, and weight may return once normal eating resumes. It’s best used as a brief dietary reset.
How long can you do the potato diet for?
The potato diet is typically followed for a duration of three days to two weeks, and it’s meant as a short-term reset, not a long-term plan. Prolonged use may lead to nutrient deficiencies due to a lack of protein, healthy fats, and dietary variety.
