What is Rice Water?
Learning more about rice water is vital to determining its effectiveness for weight loss. As the name implies, rice water is the water left over after rice is soaked or cooked in it. This water is a cloudy, starchy liquid containing various essential nutrients.
Some people claim that "Rice-Zempic," as rice water is known on TikTok, is an inexpensive alternative to weight loss medications, such as Wegovy and Ozempic.
Rice water is also touted to promote healthy hair, increase hair growth, and detangle hair.
To prepare rice water, soak rice in water for 30 minutes to 2 hours (or longer) or boil rice in water. Strain and discard the rice and drink the remaining water to boost weight loss. Some people flavor rice water with lime juice or other low-calorie flavorings.
Historical and Cultural Uses
Rice water has traditional uses in various cultures, mainly optimizing hair health and growth in Asian cultures. However, researchers have found that rice water, particularly water obtained after boiling rice, should be considered an effective anti-aging ingredient for skincare products because of its antioxidant properties.
Rice itself, particularly whole-grain rice like brown rice or wild rice, is a common staple food item due to its nutritional contributions.
Nutritional Profile of Rice Water
Rice water comprises water and the nutrients left after soaking or boiling rice.
Components of Rice Water
The key nutrients and compounds found in rice water include:
According to some sources, rice water is relatively low in calories because it consists mainly of water plus the small amounts of starch and micronutrients left behind after straining the rice. Most calories and carbohydrates remain within the rice (not the water it soaked or boiled in). However, the caloric content of rice water needs more quality evidence.
In comparison, 1/2 cup of cooked brown rice contains:
- 125 calories
- 3 grams of protein
- 26 grams of carbohydrates
- 2 grams of fiber
- 1 gram of fat
- The same micronutrients (just in more significant amounts) as rice water
Studies show that rice water is suitable for consumption and safe for human health.
Because rice water has a low caloric value and can boost satiety without adding extra calories, it has the potential to positively impact weight loss.
Evidence-Based Analysis of Rice Water for Weight Loss
An evidence-based analysis of rice water for weight loss is as follows:
Scientific Studies
Scientific research studying the effects of rice water on weight loss is lacking. However, rice water theoretically enhances weight loss as part of a well-balanced meal plan and exercise program.
Studies show that increasing water intake is an effective weight loss strategy. Scientists have found that increasing daily water consumption, replacing caloric beverages with water, and drinking water before meals boost weight loss. They suggest replacing water with higher-calorie drinks is the most effective weight-management intervention.
Furthermore, rice bran extract effectively reduces body fat in postmenopausal women. Researchers demonstrated that rice germ supplementation can boost satiety and improve body composition, body mass index (BMI), and insulin resistance.
Therefore, while studies have yet to thoroughly examine rice water's short- and long-term effects on weight loss, consuming rice extract, more plain water, or both appear to be effective weight management strategies.
Potential Mechanisms of Action
Hypothesized mechanisms of action by which rice water may influence weight loss include:
- Improved digestion
- Enhanced metabolism
- Increased satiety (feeling full)
- Reduced total calorie intake
Drinking lower-calorie rice water instead of sugar-sweetened beverages and other high-calorie drinks can significantly reduce overall calorie intake for optimal weight loss.
Consuming rice water likely affects weight loss similarly to drinking plain water or other low-calorie drinks instead of higher-calorie alternatives.
Additional weight loss options deemed effective in research studies include the Mediterranean diet, low-carb diets, and plant-based meal plans.
Potential Benefits and Limitations
Potential benefits and limitations of using rice water for weight loss include:
Possible Benefits
Drinking rice water can improve hydration. This is important because many Americans are chronically dehydrated, and staying hydrated plays a beneficial role in healthy weight management.
Rice water generally contains more micronutrients than regular water, which may support metabolic health and have antioxidant and anti-aging effects.
Limitations and Risks
A primary limitation of choosing rice water for weight loss is the need for robust clinical evidence proving this weight loss strategy works for losing weight.
There is a potential for over-relying on a single remedy, such as rice water, for weight loss instead of choosing an array of healthy habits to achieve and maintain long-term weight loss goals.
Individuals who drink rice water as a primary dietary component instead of fruits, vegetables, fiber-rich and high-protein foods, or heart-healthy fats may be at risk of nutrient deficiencies.
Lab Tests and Biomarkers to Monitor
Lab tests and biomarkers that can monitor weight loss progress and other health indicators during an individual's weight loss journey include:
Weight Loss and Metabolic Health Indicators
Routinely assessing the following helps determine the effectiveness of a healthy weight loss regimen:
- Body weight
- Body mass index (BMI)
- Waist-to-hip ratio
- Other body composition measurements
- Basal metabolic rate (BMR)
- Blood pressure
These health indicators can determine if rice water works for weight loss as designed.
Blood Tests
Blood tests to consider before, during, and after participating in a rice-water weight loss program include:
- Blood glucose tests
- Insulin levels
- Cholesterol, triglycerides, and other lipid profiles
- Hormone balance testing
- Nutrient deficiency tests
It is vital to know if any nutrient deficiencies develop due to drinking too much rice water instead of nutrient-dense whole foods.
Other Relevant Tests
Other potentially relevant tests to consider for individuals drinking rice water for weight loss include:
Kidney and liver function testing allows providers to monitor the overall health impact of rice water diets, while thyroid function tests evaluate metabolic health.
Integrating Rice Water into a Healthy Diet
There are several ways to integrate rice water into a healthy meal plan.
Balanced Approach
Consume rice water before meals to boost satiety, or drink it instead of higher-calorie sugar-sweetened drinks — such as sodas, sweet tea, lemonade, sugar-sweetened coffees, and high-sugar sports drinks.
Increase the total water intake, including rice or plain water (particularly before meals), to enhance weight loss, boost satiety, and reduce the risk of weight regain.
It's also essential to eat nutritious foods from each of the following food groups to maintain high energy and minimize the risk of nutrient deficiencies:
- Fruits
- Vegetables
- Whole grains
- Protein foods
- Dairy foods or plant-based equivalents
- Avocados, olive oil, nuts, seeds, and other heart-healthy fats
Consuming a varied, nutrient-dense, well-balanced meal plan rich in whole (non-processed) foods during and after a weight loss journey is highly beneficial. Choose sustainable eating habits for a lifetime, not just while temporarily dieting.
Limit or avoid highly processed foods. Examples include:
- Baked goods and other refined grains
- Hot dogs, sausages, and other highly processed meats
- High-fat cuts of meat
- Trans fats
- Fried foods
- Sweets
- Other snack foods high in added sugar
- Sugar-sweetened drinks
- Alcohol
While you don't have to cut out these foods entirely, limit them as much as possible to maximize health outcomes.
Combining with Other Healthy Practices
Adopting a healthy meal plan is one of many vital components of an effective weight loss plan. Pair rice water with:
- Healthy foods: Fiber- and protein-rich foods help boost satiety
- Regular physical activity: Consistent exercise increases energy expenditure and helps prevent weight gain.
- Stress reduction: Stress raises cortisol, which can inhibit weight loss.
- High-quality sleep: Studies show that sleep deprivation is an obesity risk factor.
- Avoid smoking and excessive alcohol: Alcohol may promote weight gain.
Individuals with nutrient deficiencies should take dietary supplements if their provider instructs them.
Maintaining exceptional healthy lifestyle habits offers the best chance of sustainable weight loss and long-term chronic disease prevention.
