The Rice Method is a dietary approach that has garnered attention for its potential in weight loss and management of certain health conditions. This article delves into the details of the Rice Method, exploring its origins, principles, benefits, risks, and practical implementation.
Origins and Evolution of the Rice Method
The rice diet, a high-complex carbohydrate, low-fat, and low-sodium diet, was originally developed by Walter Kempner, MD, a Duke University physician, in 1939. It regained popularity in 2006 after Kitty Gurkin Rosati, a registered dietitian specializing in the prevention of obesity, heart disease, and other chronic diseases, republished his program in her book, “The Rice Diet Solution.”
Walter Kempner originally developed the rice diet for malignant hypertension, or high blood pressure, and kidney failure. In his original cohort, the rice diet did not cure everybody, but 107 out of 192 participants saw a significant improvement in blood pressure. Many also saw a reduction in:
- heart size
- retinopathy, which refers to disease that affects the retina
- serum cholesterol levels, which is the amount of total cholesterol in a person’s blood, including high- and low-density lipoproteins and triglycerides
However, it is important to remember that at the time, people with malignant hypertension usually had a life expectancy of around 6 months. There were no drugs for managing the disease, as there are now.
Principles of the Rice Method
According to the official book, the diet works by focusing on limiting salt and foods high in sodium. This will help your body de-bloat and shed excess water weight. In combination with eating low-sodium foods, the diet also limits saturated fats. Instead, it uses high-fiber foods to fill you up and carbs like fruit, vegetables, grains, and beans as the main source of nutrition. It also limits almost all dairy from your diet. The rice diet plan also follows a calorie allowance if you’re looking to lose weight. Initially, it recommends starting at a lower calorie level and then building up to around 1,200 to 1,500 calories per day if you’re not exercising. If you follow the diet plan presented in the book, you go through three phrases that teach portion control and how to balance food so you can have the freedom to eat whatever you want in moderation.

The guidelines for Rosati’s official rice diet plan involves eating per day:
- 1,000 calories
- 500 to 1,000 mg of sodium
- 22 g of fat
- 5.5 g of saturated fat
- 0 to 100 mg of cholesterol
Key Components
- High-Complex Carbohydrates: The diet emphasizes complex carbohydrates like rice, sweet potatoes, and oatmeal, as opposed to simple carbs like cookies and cake.
- Low Fat and Sodium: The diet limits saturated fats and sodium intake, focusing on de-bloating and shedding excess water weight.
- Portion Control: The diet promotes portion control and balancing food intake.
- Lifestyle Changes: The diet focuses on lifestyle changes, such as keeping a food journal and exploring your relationship with food, your body, and self through meditation, self-awareness, and diet.
How the Rice Method Works
For the purposes of weight management, the rice diet does create a calorie deficit, which is how any diet can lead to weight loss. The rice diet is also low in sodium, which can be harmful in high amounts, and in saturated fat.
The Rice Diet Solution recommends adopting other lifestyle changes, such as practicing mindful eating, relaxation, exercise, and social connection. These can all be beneficial to well-being and may help people avoid behaviors that may undermine weight loss, such as stress eating.
Phases of the Rice Diet Solution
The Rice Diet Solution, published in 2006, aimed to help readers lose weight by adapting Kempner’s original guidelines. It did this via a calorie deficit. During the diet, a person eats 1,000 calories per day, working up to 1,200. The Rice Diet Solution has three phases. In each phase, people follow different versions of the diet for varying amounts of time per week.
The following is a guideline to the three phases outlined in The Rice Diet Solution.

Phase 1: Detox
The Rice Diet Solution book claims that its first phase cleanses the body of excess sodium, toxins, and water weight. However, it is important to note that detoxification is something the body is always doing on its own. According to the Association of UK Dietitians, there is no evidence that diets help to improve this process.
During this phase, a person follows the basic rice diet for 1 day per week. This means eating two starches and two fruits at each meal. For the rest of the week, a person eats a lactovegetarian rice diet, with nonfat dairy but no meat. This includes:
- one starch, one nonfat dairy product, and one fruit for breakfast
- three starches, three vegetables, and one fruit for lunch
- three starches, three vegetables, and one fruit for dinner
People can choose from any fruits or vegetables they wish to eat but should not add extra fat to their meals.
Phase 2: Weight Loss
This phase aims to help someone lose weight according to their health goals. The length of phase two depends on how much weight someone wants to lose. This phase consists of:
- the basic rice diet for 1 day per week
- the lactovegetarian rice diet for 5 days per week
- a vegetarian-plus rice diet for 1 day per week
The vegetarian-plus version of this diet is the same as the lactovegetarian diet, but includes a source of vegetarian protein, such as beans. This amounts to 200 more calories per day than the lactovegetarian rice diet.

Phase 3: Maintenance
This phase helps a person maintain their new weight. The authors provide guidelines for this phase but advise that once someone has reached their target weight, they may wish to make some 200 calorie additions to include fish, healthy fats, such as nuts and avocado, or dairy products. The diet consists of:
- the basic rice diet for 1 day per week
- the lactovegetarian rice diet for 4 days per week
- the vegetarian-plus rice diet for 2 days per week
Benefits of the Rice Method
- Weight Loss: The rice diet does create a calorie deficit, which is how any diet can lead to weight loss.
- Portion Control: The benefit of this diet is that it can help you learn portion control and get you started on eating more fresh fruit and vegetables.
- Heart Health: This type of diet may also be very helpful for someone who has a heart condition that requires eating a diet low in sodium and fat.
- Challenges Carb Misconceptions: One of the biggest benefits of the rice diet is that it challenges the idea that carbohydrates are a bad thing.
- Addresses Low-Carb Issues: Drastically cutting out carbs can lead to fatigue, brain fog, and hunger - but this diet prevents these symptoms by keeping your body fueled with complex carbs instead.
Potential Risks and Considerations
However, this does not make the diet a healthy one for most people. It is very restrictive and limits foods that, for those without kidney problems, are a beneficial part of a balanced diet. There are more nutritious diets that are proven to help with safe, sustainable weight loss. Both versions of the rice diet are extremely restrictive. They involve avoiding whole food groups, either for the entire diet or in certain phases of the diet, and having very limited amounts of protein or fat. This could result in:
- Muscle Loss: Low protein may cause some people to lose muscle mass or lack the amino acids necessary to synthesize protein.
- Low Energy: Everyone needs a different number of calories per day depending on their sex, size, physical activity, and other factors. The Rice Diet Solution limits all people to the same calorie intake. For some, this may result in a significant calorie deficit, and could result in fatigue, weakness, or dizziness.
- Nutritional Deficiencies: Foods that contain protein, such as meat, fish, and eggs, also contain other important nutrients that a person may find it difficult to get in sufficient quantities from the rice diet, particularly if they also avoid dairy. Some examples include B vitamins and iron. People may need to take supplements to fill these gaps. A dietitian can advise on this.
- Low Essential Fatty Acids (EFAs): Healthy fats can be a source of EFAs, such as omega-3. These are essential for many bodily functions.
Important Considerations
- Consult a Doctor: In general, people should not make dramatic changes to their diet without first consulting a doctor. This is especially true if they take medications, have any preexisting health conditions, or if they have a history of restrictive dieting or disordered eating.
- Specific Conditions: The authors of The Rice Diet Solution advise that people taking drugs for diabetes, high blood pressure, or other cardiovascular diseases consult a doctor before trying this diet.
- Contraindications: In addition, people who have had surgery on their colon, ureteral diversion procedures, or impaired kidney function should not follow the diet. Anyone who feels unwell or dizzy while following the rice diet should stop following the program and speak with a medical professional.
- “Because the Rice Diet is very strict and low in calories, pregnant women, young children, and those with a history of eating disorders shouldn’t try it,” Woods says. A low-sodium diet may also be risky for certain people, such as older adults and those who do long-distance endurance exercise. Talk to your health care provider first if you’re thinking about trying the Rice Diet.
Incorporating Exotic Rice Varieties
Exotic rice is incredibly versatile and flavorful. Here are some tips for incorporating it into your meals:
- Gradually swap out white rice for exotic varieties.
- Introduce these new flavors one step at a time.
- Experiment with different types of exotic rice, including black, brown, red, and even purple rice. Each offers a unique taste and texture.
- Exotic rice can be prepared using various methods, including boiling, steaming, or using a rice cooker.
- Don’t limit exotic rice to just side dishes. Add it to salads, bowls, pilafs, or even create a warm and comforting rice porridge.
- Aim for 3-5 servings of whole grains, including exotic rice, per day.
The good news is that exotic rice is naturally gluten-free and is becoming increasingly available in grocery stores, health food stores, and online retailers.
Rice Recipes for Weight Loss
With the right recipes, rice can be a delicious and satisfying part of your weight loss journey. Here are a few ideas to get you started:
- Low-Calorie Fried Rice: Swap out white rice for brown or cauliflower rice, load up on veggies, and use a lean protein like chicken or shrimp. A sprinkle of soy sauce and sesame oil adds flavor without the guilt.
- Hearty Rice Bowls: Create customizable rice bowls by combining cooked brown rice with grilled chicken or tofu, roasted vegetables, and a drizzle of low-calorie dressing. Experiment with different flavors and toppings to keep things interesting.
- Rice Pilaf with Vegetables: A classic pilaf gets a healthy makeover with brown rice and colorful vegetables. Add herbs and spices for extra flavor. Serve as a side dish or a main course with grilled fish or chicken.
- Rice Pudding with Greek Yogurt: Satisfy your sweet tooth with a lighter version of rice pudding. Use low-fat milk, Greek yogurt, and a touch of natural sweetener. Top with fresh berries for added flavor and antioxidants.
- Rice-Based Soups: Warm up with a comforting rice-based soup. Use brown rice as a base for a vegetable-packed broth, or create a creamy coconut milk soup with wild rice.

The Rice Method in Practice
The Rice Method is a straightforward and effective approach to weight loss that focuses on portion control. Named for using rice as a visual guide for serving sizes, this method helps you understand how much food you should eat while still enjoying your favourite meals. At its core, the Rice Method involves using a serving of rice as a reference point for portion sizes. The idea is that one serving of cooked rice (about 1/2 cup) can be used to gauge the amount of other foods you should eat. Focus on whole foods: Prioritise whole, unprocessed foods like vegetables, lean proteins, and whole grains. Slow down while eating: Take your time with meals.
For example, when preparing your plate, you can fill half of it with vegetables, a quarter with lean protein (like chicken or fish), and the other quarter with a healthy carbohydrate source, such as rice or quinoa.
Research and Studies
In 1975, Kempner and other researchers tested the diet in combination with exercise as a treatment for obesity in 106 people. All participants lost at least 45 kilograms (99 pounds) over the duration of the study. But the study did not follow the participants to determine if the weight loss was sustainable once the study was over. There are also no studies evaluating if the newer version of the rice diet in The Rice Diet Solution is a safe or effective weight loss method.
Expert Opinions
“The Rice Diet is extremely strict,” says Dolores Woods, RD, nutritionist with UTHealth Houston. You’re going to cut way down on calories, salt, fat, and sugar - all at once. The food on the plan doesn’t give you enough calcium and vitamin D, so you will need supplements. Also, the plan offers much less protein than what’s recommended for healthy people. If you have a medical condition, check with your doctor before starting this diet.
Because the Rice Diet has been around for decades, researchers show that it is safe when followed correctly and done under medical supervision. “Because the diet is very strict, it has nutritional deficiency,” says Woods. It falls short in vitamin D and calcium, so you’ll need to take supplements. It’s also low in protein, which can lead to muscle loss, especially in older adults. “You may also feel dizzy or tired because you’re not getting enough calories or electrolytes,” she says.
Conclusion
The Rice Method, particularly as presented in "The Rice Diet Solution," can lead to weight loss due to its low-calorie nature. It emphasizes whole foods, portion control, and lifestyle changes, which can be beneficial for some individuals. However, its restrictive nature and potential for nutritional deficiencies raise concerns about its long-term sustainability and overall healthfulness. Individuals considering the Rice Method should consult with a healthcare professional to determine if it is appropriate for their specific needs and health conditions. A balanced approach that incorporates a variety of nutrient-dense foods and sustainable lifestyle habits is generally recommended for long-term weight management and overall well-being.
