Potato soup, a classic comfort food, can be a surprisingly valuable tool in your weight loss journey. The key lies in how you prepare it, focusing on nutrient-rich ingredients and mindful cooking techniques. While the "potato diet" itself is a restrictive fad with questionable long-term benefits, incorporating a well-made potato soup into a balanced diet can be a delicious and effective strategy for managing your weight.
Understanding the Potato Diet
The potato diet, or "potato hack," is a short-term, restrictive diet that has gained popularity due to its promise of rapid weight loss. This diet typically involves eating nothing but plain potatoes for 3-5 days, with the goal of losing up to one pound (0.45 kg) per day.
Tim Steele's "Potato Hack: Weight Loss Simplified" (2016) popularized this concept, suggesting that potatoes are the "best diet pill ever invented." Proponents claim that potatoes can strengthen the immune system, improve gut health, and provide ample nutrients while aiding weight loss. Penn Jillette, a magician, followed a potato-only diet for the first two weeks of his weight loss journey, reportedly losing 18 pounds (8 kgs).
The fundamental rules of the potato diet, as outlined by Tim Steele, are as follows:
- Eat only plain potatoes for 3-5 days.
- Aim to eat 2-5 pounds (0.9-2.3 kg) of potatoes daily.
- Avoid other foods, including condiments and toppings like ketchup, butter, sour cream, and cheese.
- Salt is permissible, but try to avoid it.
- Drink only water, plain tea, or black coffee.
- Stick to light exercise and walking, avoiding heavy exercise.
- Continue taking prescribed medications as directed by your physician, but avoid unprescribed dietary supplements.
While Steele's version allows only white potatoes, some variations, like the Spud Fit Challenge created by Andrew Taylor, permit sweet potatoes and minimal herbs, spices, and fat-free condiments. It's crucial to avoid fried or overly processed potato products like French fries or potato chips.

Though the potato diet might lead to short-term weight loss due to its low calorie content of 530-1,300 calories from 2-5 pounds (0.9-2.3 kgs) of potatoes daily, it's not a sustainable long-term solution. Potatoes contain proteinase inhibitor 2 (PI2), a compound that may reduce hunger by slowing digestion. A 2016 study on mice found that PI2 treatment led to reduced food intake and weight loss, but these effects are yet to be studied in humans.
The Pros and Cons of the Potato Diet
While the potato diet may offer some potential benefits, it also has significant drawbacks.
Potential Benefits
- Nutritious: Potatoes are a good source of essential vitamins and minerals, including vitamin C, potassium, folate, and iron.
- Simple: The diet is easy to understand, requiring only the consumption of plain potatoes for a few days.
- Affordable: Potatoes are typically an inexpensive type of fresh produce.
- High in Fiber: High-fiber diets can promote gut health and may help prevent obesity, heart disease, and type 2 diabetes.
Significant Downsides
- Extremely Restrictive: The diet is highly restrictive, making it difficult to adhere to and potentially leading to an unhealthy relationship with food and disordered eating behaviors like binge eating. It also encourages skipping meals and fasting, which are unnecessary given the diet's already low-calorie nature.
- Lacks Essential Nutrients: Potatoes do not provide all the nutrients needed for optimal health, particularly protein and fat. A medium-sized potato contains about 4 grams of protein and virtually no fat. Long-term or frequent adherence to the diet could lead to nutrient deficiencies.
- May Cause Muscle Loss: Rapid weight loss from very low-calorie diets like the potato diet can lead to muscle loss. A 2016 study found that 18% of weight loss on a 500-calorie-per-day diet was from lean body mass, compared to 8% on a 1,250-calorie-per-day diet. The potato diet lacks a high-quality protein source, which can help reduce muscle loss during calorie restriction.
- May Result in Unintended Weight Gain: Very low-calorie diets can cause the body to slow down its metabolism, burning fewer calories. This "adaptive thermogenesis" may persist for years, making long-term weight maintenance difficult. Studies estimate that over 80% of dieters regain their previous weight over time.
Crafting a Weight-Loss-Friendly Potato Soup
Rather than relying on the restrictive potato diet, consider incorporating potato soup into a balanced eating plan. When made with the right ingredients, potato soup can be both nutritious and low in calories, making it a valuable tool for weight management.
Key Ingredients for Weight Loss
- Vegetables: Load up your soup with non-starchy vegetables like onions, carrots, celery, kale, and spinach. These are low in calories, high in nutrients, and add bulk to keep you feeling full.
- Lean Protein: Add lean protein sources like beans, lentils, or shredded boneless, skinless white meat chicken. Protein helps you feel fuller for longer, which can aid in weight management. A diet rich in protein can help you feel fuller than lower-protein diets.
- Fiber: Include high-fiber ingredients to slow digestion, promote gut health, and help you stick to a healthy weight. Vegetables, beans, and lentils are all excellent sources of fiber.
- Potatoes: Choose potatoes wisely. While white potatoes can be part of a healthy diet, consider using a mix of potatoes, including sweet potatoes, for added nutrients and variety.
Smart Cooking Techniques
- Control Your Portions: Be mindful of portion sizes to manage your calorie intake.
- Limit Fat: Avoid adding excessive amounts of fat, such as butter or cream. Instead, use low-fat milk, evaporated milk, or vegetable broth to create a creamy texture.
- Watch the Sodium: Be mindful of the sodium content in your soup. Use low-sodium broth and seasonings, and avoid adding excessive salt. Rinsing canned beans can also help reduce sodium.
- Embrace Flavor: Use herbs, spices, and other flavorings to make your soup delicious without adding extra calories or unhealthy ingredients.
