The ketogenic diet is a low-carb, high-fat diet that has gained popularity in recent years. While the diet has shown some promising results for weight loss and improved health, it is important to understand the difference between complex and simple carbohydrates to make informed choices. Complex carbohydrates, such as starches and fiber, take longer for the body to break down, resulting in a slower release of glucose and avoiding spikes in blood sugar levels. On the other hand, simple carbohydrates like sugars are quickly digested, leading to a rapid increase in blood glucose and potential health issues like diabetes. Despite the benefits of complex carbs, some simple carbohydrates are healthier than certain complex ones, and focusing on whole foods that are rich in fiber and nutrients is recommended.
Are complex carbs better than simple carbs in a ketogenic diet?

Simple carbs are found in processed foods or those with added sugar
Simple carbohydrates, or sugars, are typically found in processed foods or those with added sugar. Adding sugar to food increases its calorie content without providing any additional nutrition. This is why it is recommended to eat whole fruits instead of fruit juice. Whole fruits contain more dietary fibre and are a better option.
Simple carbs are also present in healthful foods, such as milk and whole fruits, which contain a variety of necessary vitamins, minerals, and other nutrients. However, they are more commonly found in foods with low nutritional value, such as sugary drinks, candy, and baked goods. These foods are often highly processed and contain refined sugars and grains, such as white flour and white rice, which can cause blood sugar levels to rise quickly.
Simple carbohydrates are digested quickly, providing the body with a short-lasting source of energy. This leads to a spike in blood glucose, followed by a release of insulin, which helps move glucose from the blood into the cells. After this process, you may feel tired and hungry again. This is why simple carbs are often associated with a "sugar rush" followed by a crash.
To identify if a food contains a lot of simple carbs, you can check the amount of "added sugars" on the nutrition label. Foods containing more than 10 grams of added sugars per serving are considered high in simple carbs. Some common sources of added sugars include sugar, corn syrup, dextrose, fructose, honey, and molasses.

Complex carbs are found in whole grains, fruits and starchy vegetables
Complex carbohydrates are made from three or more sugars bonded together, making them harder for the body to break down and digest. This leads to a more gradual increase in blood sugar compared to simple carbs. Complex carbs are rich in fibre, vitamins, minerals, and other beneficial compounds. They are found in whole grains, fruits, starchy vegetables, and pulses.
Whole grains contain all three parts of the grain kernel—the germ or core, the endosperm or middle layer, and the hard outer layer called the bran. These parts house important nutrients like fibre, vitamins, and minerals. Refined grains, on the other hand, have their bran and germ removed, making them less nutritious. Examples of whole grains include brown rice, whole wheat bread, and quinoa.
Fruits are another excellent source of complex carbohydrates. They are not only sweet and delicious but also high in fibre, vitamins, minerals, and protective plant compounds. A diet rich in fruits can provide various health benefits and help reduce the risk of certain chronic diseases. Some fruits that are particularly good sources of complex carbs include apples, bananas, oranges, and berries.
Starchy vegetables, such as potatoes, sweet potatoes, and corn, are also good sources of complex carbohydrates. These vegetables are high in starch, a type of complex carb, and provide various essential nutrients. Including starchy vegetables in your diet can help promote digestive health and provide a good source of energy.
In conclusion, complex carbs found in whole grains, fruits, and starchy vegetables offer numerous health benefits due to their high fibre, vitamin, and mineral content. They are a key part of a healthy diet and can help reduce the risk of chronic diseases, maintain a healthy weight, and improve overall health.

Simple carbs are sugars, complex carbs are fibre and starch
Carbohydrates are made up of three components: fibre, starch, and sugar. Fibre and starch are complex carbs, while sugar is a simple carb. Complex carbohydrates are digested more slowly and release glucose into the bloodstream more gradually. In contrast, simple carbohydrates are broken down quickly by the body to be used as energy. This leads to a spike in blood sugar levels, followed by a quick drop.
Simple carbs are sugars that occur naturally in foods such as fruits, milk, and milk products. They are also found in processed and refined sugars such as candy, table sugar, syrups, and soft drinks. Most of the simple carbs in the American diet are added to foods. These include sugary soda, baked goods, and breakfast cereals. While fruit juice contains more vitamins and fibre than soft drinks, it is still full of natural sugars, a type of simple carbohydrate.
Complex carbs, on the other hand, pack in more nutrients than simple carbs. They are higher in fibre and digest more slowly, making them more filling. This makes them a good option for weight control and ideal for people with type 2 diabetes. Complex carbs are found in whole grains, beans and legumes, fruits, vegetables, and whole-grain products.
Your body needs all three forms of carbohydrates to function properly. However, it is recommended that the majority of your carbohydrate intake should come from complex carbohydrates rather than processed or refined sugars. This is because complex carbs provide more nutrients and help maintain stable blood sugar levels.

Complex carbs are recommended by mainstream medical and nutrition agencies
Complex carbohydrates are recommended by mainstream medical and nutrition agencies due to their ability to provide long-term health benefits. They are key to maintaining a healthy weight and can help prevent type 2 diabetes and cardiovascular issues. Unlike simple carbs, which are typically found in processed foods and added sugars, complex carbs are a source of fibre and starch, found in whole foods such as starchy vegetables, legumes, and whole grains. These include foods like sweet potatoes, peas, corn, beans, lentils, and whole wheat products.
The CDC, for example, recommends choosing complex carbs to get the most nutrition with the least impact on blood sugar. This is because complex carbs take longer for the body to digest, resulting in a slower increase in blood sugar levels. They also provide fibre and other nutrients that are essential for the body and brain to function properly. The CDC suggests opting for whole wheat flour over enriched, unbleached, or multigrain flour and choosing whole fruits over fruit juice to increase fibre intake.
Additionally, complex carbs can be found in grains such as quinoa, farro, bulgur wheat, barley, and millet, which offer a nutritional boost along with extra flavour. These whole grains are recommended as an alternative to refined grains, which are simple carbs that have been processed to remove fibre and key nutrients. Refined grains are often found in white bread, white rice, white pasta, cereals, pastries, and desserts, and while they are more affordable and have a longer shelf life, they offer less nutritional value.
Mainstream medical and nutrition agencies also recommend complex carbs because they can help guard against certain health conditions. For example, the DASH diet, recommended by the CDC, suggests reducing blood pressure in people with type 2 diabetes by choosing healthy carbs with a focus on complex carbohydrates. Similarly, the nutritional profile of complex carbs can benefit those with diabetes by helping to manage blood sugar levels more effectively than simple carbs.

Complex carbs are less likely to cause spikes in blood sugar
Complex carbohydrates are widely considered healthier than simple carbohydrates. They are key to long-term health, making it easier to maintain a healthy weight and even guarding against type 2 diabetes and cardiovascular issues.
Simple carbs are typically found in processed foods or those with added sugars. While some natural foods like milk contain simple carbs, most simple carbs in the American diet are added to foods, increasing their calorie content without providing additional nutrition.
Complex carbs, including starches and fibres, are found in whole foods like beans, whole grains, fruits, and vegetables. These complex carbs are highly nutritious and provide essential fuel for the brain and muscles. Studies show that a diet rich in these complex carbohydrates is associated with a lower risk for heart disease, type 2 diabetes, and obesity.
However, it's important to note that not all complex carbs are always the healthier choice, especially when it comes to starchy foods. Some simple carbohydrates, like those in whole fruits, can be a better option than starchy complex carbs. Ultimately, it's recommended to consider the overall nutritional profile of a food rather than solely focusing on the type of carbohydrate it contains.
