How Your Body Processes Sugar On Keto

The ketogenic diet is a low-carb, high-fat diet that aims to shift the body into a metabolic state called ketosis. By drastically reducing carbohydrates, the body is forced to burn fat for energy, which can lead to weight loss and other potential health benefits. Sugar is a type of carbohydrate, and on keto, carbs are kept to a minimum. When we eat carbs, they are broken down into glucose, which can be harmful if consumed excessively. The keto diet limits sugar to 20-30 grams daily or less to stay in ketosis. This is low compared to the typical American diet, which can include 100-150 grams of sugar per day.

Sugar is a type of carbohydrate, so it's limited on keto

The keto diet is a low-carb, high-fat diet that aims to shift the body into a metabolic state called ketosis. By drastically reducing carbohydrates, the body is forced to burn fat for energy, which can lead to weight loss and other potential health benefits.

Sugar is a type of carbohydrate, so it is limited on keto. When we eat carbs, our body breaks them down into glucose, which can cause health problems if consumed excessively. Excess sugar intake has been linked to an increased risk of heart disease, insulin resistance, type 2 diabetes, high blood pressure, nonalcoholic fatty liver disease, and even tooth enamel damage.

The ketogenic diet recommends keeping carbohydrate intake to a minimum, typically around 50 grams or less per day. This includes all sources of carbohydrates, including refined sugar. However, it is important to note that not all sugars are the same. Natural sugars, such as those found in fruit and dairy products, are generally considered healthier and can be included in a keto diet in moderation. For example, blackberries and asparagus are low in sugar and have a lot of health benefits, such as vitamins and fiber.

On the other hand, added sugars, which are commonly found in processed foods, are not recommended on the keto diet. These are often referred to as "empty calories" because they provide no nutritional benefits and can hinder weight loss. It is best to avoid added sugars as much as possible and choose natural sweeteners like stevia, monk fruit, or erythritol instead.

While it is recommended to keep sugar consumption to a minimum on keto, it is not always possible to eliminate it completely. As long as you stay within your daily carbohydrate limit, typically between 20 and 50 grams, you should be fine. However, it is important to note that everyone's biochemistry is different, and the amount of sugar and carbohydrates you can tolerate may vary.

In summary, sugar is limited on the keto diet because it is a type of carbohydrate, and carbohydrates need to be kept low to maintain ketosis. By reducing sugar intake, individuals can not only stay within the keto guidelines but also potentially improve their health and reduce their risk of certain diseases.

Excess sugar is linked to health issues like heart disease and type 2 diabetes

Excess sugar is linked to a number of health issues, including heart disease and type 2 diabetes.

When you eat sugar, it travels to your stomach, where it is broken down into glucose. The glucose then moves into your small intestine, is absorbed through your intestinal wall, and is released into your bloodstream. From there, your blood carries glucose throughout your body, using it to feed cells that need energy.

The issue with eating sugar and other refined carbs is the speed at which they are absorbed into your bloodstream. Because they are already refined, your digestion has minimal work to do to break them down into glucose. As a result, sugar enters your bloodstream very quickly, and too much of it will cause a sudden spike in your blood glucose levels.

High blood sugar levels (hyperglycaemia) damage your organs and blood vessels. When your blood sugar gets too high, your pancreas releases insulin, a hormone that controls how you process sugar. Insulin tells your liver and cells to pull sugar out of your bloodstream and store it, reducing your blood sugar levels back to a safe range.

However, when you eat a lot of sugar at once, your body may overcorrect. In its haste to bring your blood sugar levels back down, insulin pulls too much sugar from your blood, and you end up with low blood sugar. This is the science of a sugar crash.

The longer the cycle of sugar crashes and sugar cravings goes on, the more desensitised your body becomes to insulin. This desensitisation leads to insulin resistance, a sign of pre-diabetes and a risk factor for cardiovascular disease.

Excess sugar consumption has been linked to an increased risk of heart disease. A 2014 study published in JAMA Internal Medicine found that people who got 17% to 21% of their calories from added sugar had a 38% higher risk of dying from cardiovascular disease compared to those who consumed 8% of their calories as added sugar.

Consuming too much added sugar can also raise blood pressure and increase chronic inflammation, both of which are risk factors for heart disease. In addition, excess sugar consumption contributes to weight gain, which is another risk factor for heart disease.

Excess sugar consumption is also linked to an increased risk of type 2 diabetes. When you eat too much sugar, your body may stop responding properly to insulin, leading to insulin resistance. Over time, your pancreas may break down, and your blood sugar levels will rise, setting the stage for type 2 diabetes.

Natural sugars are found in fruits and vegetables, but they're best in moderation

Natural sugars are found in fruits and vegetables, but they are best enjoyed in moderation. While fruits and vegetables are essential components of a healthy, balanced diet, providing dietary fibre, vitamins, minerals, and phytonutrients, some contain higher amounts of natural sugars than others.

Fruits and vegetables contain a range of naturally occurring sugars, including disaccharides like sucrose and monosaccharides like fructose and glucose. The ratio of these sugars depends on the specific type and variety of fruit or vegetable. For example, an apple typically contains around 10-13g of sugar per 100g, while a banana may have up to 18.2g of sugar per 100g.

While natural sugars from fruits and vegetables can be part of a healthy diet, excessive sugar intake, especially in the form of added sugars, can have negative health effects. High sugar consumption has been linked to an increased risk of heart disease, insulin resistance, type 2 diabetes, high blood pressure, non-alcoholic fatty liver disease, and tooth enamel damage. It can also contribute to weight gain and sugar cravings, making it harder to maintain a healthy weight.

Therefore, it is important to be mindful of the sugar content of the fruits and vegetables we consume and to prioritise those with lower sugar content. Additionally, it is crucial to limit the intake of added sugars, which are commonly found in processed foods and sugar-sweetened beverages. These added sugars are more quickly metabolised by the body and can lead to sudden spikes in blood glucose levels, contributing to the negative health effects associated with high sugar consumption.

In conclusion, while natural sugars from fruits and vegetables can be part of a healthy and balanced diet, moderation is key. Prioritising lower-sugar options and limiting added sugars can help maintain overall health and reduce the risk of sugar-related health issues.

Added sugars are common in processed foods and are best avoided on keto

The keto diet is a low-carb, high-fat diet that helps the body enter a metabolic state called ketosis, where it burns fat instead of carbohydrates for energy. This can lead to weight loss and other health benefits. However, to stay in ketosis, it is crucial to keep carbohydrate and sugar intake to a minimum.

Added sugars are commonly found in processed foods, and they are considered empty calories on the keto diet. These added sugars provide zero nutritional benefits and can hinder your efforts to stay within your daily calorie limit. They also contribute to increased calorie intake, which can lead to weight gain and other health issues. Therefore, it is best to avoid added sugars as much as possible when following a keto diet.

The distinction between added sugar and naturally occurring sugar is essential. Naturally occurring sugars, such as lactose in milk and fructose in fruits, are not inherently bad. However, they still need to be considered when tracking carbohydrate intake on a keto diet. For example, while blackberries are low in sugar, they contain 6.2 grams of net carbs per cup. On the other hand, a serving of asparagus only has 1.9 net grams of carbs, making it a better choice for those on a keto diet.

It is worth noting that not all sugars are equal. Natural sugars found in fruits and vegetables can be part of a healthy diet in moderation, even when following keto. However, it is crucial to monitor your intake to ensure you stay within your daily carbohydrate limits.

To summarise, while it may be challenging to eliminate added sugars entirely, significantly reducing them is crucial for staying in ketosis and achieving the desired results on a keto diet. Natural sugars from fruits and vegetables can be consumed in moderation, but tracking your intake is essential to ensure you don't exceed your daily carbohydrate limits.

Sugar alternatives like stevia or monk fruit can be used in keto-friendly treats

Sugar Alternatives for Keto-Friendly Treats

Sugar alternatives like stevia, monk fruit, erythritol, and xylitol can be used to sweeten keto-friendly treats without impacting blood sugar levels or kicking you out of ketosis. Here's a detailed look at these sugar alternatives:

Stevia

Stevia is a natural sweetener derived from the Stevia rebaudiana plant, which is native to South America. It is a nonnutritive sweetener, containing zero calories, carbohydrates, or other nutrients, making it ideal for a keto diet. The active compounds in stevia can be 30-150 times sweeter than sugar, so a little goes a long way. It has a familiar sweet flavor, but some varieties may have a slightly bitter aftertaste. Stevia is available in powdered, granulated, and liquid forms, with drops being the most advisable due to potential fillers in the powdered and granulated versions. Studies suggest that stevia has no effect on blood sugar response and may even help lower blood sugar and blood pressure, making it a popular choice for people with diabetes and low-carb dieters. The FDA recognizes refined stevia extracts as safe, while raw and whole leaf extracts are not approved due to a lack of toxicological information.

Monk Fruit

Monk fruit is a natural sweetener extracted from the monk fruit plant, native to Southeast Asia. It has been used as a tonic herb in traditional Chinese medicine for thousands of years. Like stevia, monk fruit contains zero calories, zero carbs, and does not appear to raise blood sugar or insulin levels. Monk fruit is rich in antioxidants known as mogrosides, which contribute to its sweetness, ranging from 100-250 times sweeter than sugar. One potential downside of monk fruit is its expense, and since it is a relatively new product, long-term impact studies are not yet available.

Erythritol

Erythritol is a sugar alcohol with a similar structure to sugar but is only partially digested by the body. It is typically created by fermenting glucose from wheat or corn starch, resulting in a fine white powder or granules. Erythritol is not completely calorie-free, containing 0.24 calories per gram compared to 4 calories per gram of table sugar. Studies suggest that erythritol, like stevia and monk fruit, has no impact on blood sugar levels. Erythritol is generally considered safe, but it may cause nausea if consumed in large doses (50 grams in a single serving). Interestingly, erythritol has been shown to be more effective than xylitol and sorbitol in fighting dental plaque and caries.

Xylitol

Xylitol is another sugar alcohol with a sweetness similar to regular sugar. It contains 2.4 kcal per gram, about two-thirds of that found in standard table sugar. Animal studies suggest that xylitol can contribute to a reduction in body weight, blood sugar, and increased insulin concentration in diabetic rats. However, xylitol has been associated with digestive problems when used in high doses, so it is recommended to scale back intake if any adverse effects are noticed.
