The ketogenic diet is a low-carbohydrate method of eating that shifts your metabolism into a state of ketosis, where your body burns fat for fuel instead of carbohydrates. While rice is a staple food for many, it is not keto-friendly due to its high carbohydrate content. White rice, for example, contains around 45-53 grams of carbohydrates per cup, while brown rice has around 45-46 grams. Even small amounts of rice can cause your body to fall out of ketosis, so it is generally recommended to avoid rice on a keto diet. However, some people may be able to consume a very small amount of rice, such as half a cup, without disrupting ketosis, especially if they are athletes or following a cyclical ketogenic diet.

What You'll Learn
White rice is high in carbohydrates
White rice is a refined carbohydrate that is high in carbs and low in fiber. A cup of cooked, enriched short-grain white rice contains around 53 grams of net carbohydrates, while brown rice contains around 46 grams. White rice is processed in a way that removes much of its fiber, minerals, and vitamins. This makes it less nutritious than brown rice, which contains more fiber, magnesium, and selenium.
The keto diet is a low-carbohydrate method of eating that aims to shift the body's metabolism into a state of ketosis, where it burns fat for fuel instead of carbohydrates. To maintain ketosis, most keto dieters aim for a daily carbohydrate intake of fewer than 50 grams, with some therapeutic keto diets recommending less than 20 grams.
Due to its high carbohydrate content, white rice is not considered keto-friendly. Eating a cup of white rice can easily exceed the daily carb limit for keto dieters, potentially kicking them out of ketosis. However, some sources suggest that it is possible to consume small amounts of white rice without dropping out of ketosis, as long as one closely monitors their total carbohydrate intake.
The glycemic index (GI) of cooked white rice is 70, which is relatively high. A high GI food quickly raises blood glucose levels, which can lead to blood sugar spikes. This is in contrast to foods with a lower glycemic index, which help prevent blood sugar spikes and are key to preventing type 2 diabetes.
While white rice is not ideal for maintaining ketosis, it is a versatile grain that is a staple in many dishes and cultures. It is important to note that the keto diet is known for its extremes and restrictions, and those considering it should be mindful of the potential risk of nutrient deficiencies.

White rice has a high glycemic index
White rice is not recommended for a keto diet due to its high glycemic index (GI). The GI of cooked white rice is 70, which is relatively high compared to other foods. A high GI indicates that a food causes a rapid and significant increase in blood glucose levels. This is because white rice is a refined carbohydrate, meaning it has been processed and stripped of most of its fiber and nutrients. As a result, it is quickly broken down and absorbed by the body, leading to a spike in blood sugar.
In contrast, whole grain rice, such as brown rice, has a lower GI of 68. This is because it retains more fiber and nutrients, which slow down the digestion process and prevent a sharp rise in blood glucose. However, even brown rice is not considered keto-friendly, as it still contains a significant amount of carbohydrates. A cup of cooked brown rice can contain around 45-46 grams of net carbohydrates, which is well above the recommended daily intake of fewer than 50 grams for keto dieters.
The goal of a ketogenic diet is to achieve ketosis, a metabolic state where the body burns fat for energy instead of carbohydrates. To reach and maintain ketosis, keto dieters typically aim for a daily carbohydrate intake of fewer than 50 grams, with some following a more restrictive therapeutic keto diet of fewer than 20 grams. White rice, with its high carbohydrate content and glycemic index, can easily cause a person to exceed this limit and hinder their progress toward ketosis.
While some sources suggest that small amounts of white rice may be consumed without disrupting ketosis, it is crucial to closely monitor carbohydrate intake. Additionally, resistant starch rice, which involves cooking the rice and then cooling it overnight before consumption, may be a potential option as it lowers the net carbohydrates in the rice. However, the effectiveness of this method in significantly reducing net carbs is questionable.
Overall, white rice's high glycemic index and carbohydrate content make it challenging to include in a keto diet without careful planning and portion control. It is important for keto dieters to be mindful of their carbohydrate intake and choose low-carb alternatives to maintain their desired nutritional goals.

White rice alternatives for keto dieters
White rice is not considered keto-friendly due to its high carbohydrate content. A cup of cooked, enriched short-grain white rice contains around 53 grams of net carbohydrates, which is significantly more than the recommended daily intake of fewer than 50 grams, or even 20 grams for some keto diets.
Therefore, those on a keto diet may want to consider the following alternatives to white rice:
Riced Cauliflower
Riced cauliflower is one of the most popular low-calorie and low-carb substitutes for white rice. It has a similar look and texture to white rice, with only 13 calories per 1/2-cup (57-gram) serving, compared to 100 calories for the same serving of white rice. It can be easily prepared by grating cauliflower with a box grater or food processor and then cooking it over medium heat with some oil until tender.
Riced Broccoli
Similar to riced cauliflower, riced broccoli is another excellent source of vitamin C, with 1/2 cup (57 grams) providing over 25% of the daily recommended value. It is also low in calories and carbohydrates, making it a suitable alternative for keto dieters.
Shirataki Rice
Shirataki rice is made from konjac root, which is native to Asia and rich in a unique fiber called glucomannan. It is a popular low-carb and low-calorie alternative to white rice, with a 3-ounce (85-gram) serving containing virtually no calories. To prepare shirataki rice, simply rinse it, boil it for one minute, and then heat it in a pan until dry.
Quinoa
Quinoa is technically a seed, but it is often treated like a grain and can be used as a rice substitute. It is gluten-free, high in protein, and contains all nine essential amino acids. However, it is still relatively high in starchy carbohydrates, so it should only be consumed occasionally or in small portions.
Mushrooms
Mushrooms make for a great savoury and earthy-flavoured keto substitute for rice. Sliced white mushrooms have just 2 grams of carbs per cup, and they can be easily prepared by sautéing them in a pan with butter. They can also be combined with other low-carb rice alternatives for added variety.

The health benefits of white rice
White rice is not considered keto-friendly due to its high carbohydrate content. However, it does offer some health benefits when consumed in moderation as part of a balanced diet.
Firstly, white rice is easy to digest, especially for individuals with irritable bowel syndrome or inflammatory bowel disease who need to monitor their fibre intake. Its low fibre content also contributes to its softer texture and faster cooking time compared to brown rice.
Secondly, white rice is typically enriched with added nutrients during processing, such as iron and B vitamins like folic acid, niacin, and thiamine. This process improves its taste, extends its shelf life, and makes it a good source of essential vitamins and minerals.
Additionally, white rice is a gluten-free food, making it a suitable and nutritious option for people with celiac disease who may struggle to digest certain grains.
When combined with nutrient-rich foods like vegetables, white rice can be part of a healthy and balanced diet. However, it is important to monitor portion sizes and overall carbohydrate intake, especially for those following a keto diet or aiming for weight loss, as white rice is high in starch and carbohydrates, which can contribute to weight gain and increased blood sugar levels.

How much white rice can be eaten on keto
White rice is not considered keto-friendly due to its high carbohydrate content. A cup of cooked, enriched short-grain white rice contains around 53 grams of net carbohydrates, while brown rice contains around 46 grams. Most keto dieters aim for a daily carbohydrate intake of fewer than 50 grams, with some therapeutic keto diets aiming for under 20 grams.
While it is generally recommended to avoid white rice on a keto diet, it is possible to consume small amounts without dropping out of ketosis. The key is to monitor your total carbohydrate intake and keep the portion size very small. A quarter cup of brown rice, for example, contains around 9 grams of carbohydrates, which could fit within your daily carb limit.
To reduce the net carbohydrates in white or brown rice, you can prepare resistant starch rice by cooking the rice and then letting it sit in the fridge overnight before consuming it. As cooked rice cools, the carbohydrate chains become longer and more complex, reaching a point where some of it cannot be digested by the human body. However, it is unclear if the reduction in net carbs is significant enough to make resistant starch rice a viable option for keto dieters.
It is important to note that rice, even in small amounts, may not align with a keto diet's strict rules about carbohydrates. Other foods that are conventionally considered healthy, such as fruits, legumes, dairy, starchy vegetables, and whole grains, are also limited or avoided on keto due to their high carb content.
If you are craving rice, there are several low-carb rice alternatives available to satisfy your cravings without hindering your progress on a keto diet.
