Cornstarch is a staple ingredient used as a thickening agent in various dishes. However, it has a high carbohydrate content, with 90.37g of net carbs per 100g serving. This makes it a poor choice for a ketogenic diet, which is a low-carbohydrate, high-fat diet intended to put the body in a state of ketosis. Cornstarch also has a high glycemic index, which means it can cause rapid spikes in blood sugar levels, leading to potential health issues such as cardiovascular disease and insulin resistance. Therefore, it is generally recommended to avoid cornstarch when following a ketogenic diet and instead opt for low-carb alternatives such as almond flour, xanthan gum, or gelatin. These substitutes can provide similar textural properties without the adverse health effects associated with cornstarch.

What You'll Learn
Cornstarch is high in carbohydrates
Cornstarch is a thickening agent often used to improve the texture of soups, sauces, marinades, and desserts. It is made from the endosperm of corn kernel seeds, which makes up about 82% of the kernels' dry weight.
The high carb content of cornstarch can cause a rapid increase in blood sugar levels, which is detrimental to those with diabetes or insulin resistance. Chronically elevated blood sugar levels, known as hyperglycemia, are linked to an increased risk of cardiovascular disease, type 2 diabetes, and excess abdominal fat.
In addition to its high carb content, cornstarch is also highly processed and lacks essential nutrients like vitamins, minerals, fiber, and protein. It is important to note that while cornstarch can be enjoyed in small amounts as part of a balanced diet, its regular consumption may negatively affect heart health due to its impact on blood sugar levels.
When following a ketogenic diet, it is best to avoid cornstarch and opt for low-carb alternatives such as almond flour, coconut flour, flax meal, or chia seeds. These substitutes can provide similar textures and consistencies without the high carb count, allowing individuals to achieve their weight loss and health goals while still enjoying their favorite recipes.

It is ultra-processed
Cornstarch is ultra-processed and has no nutritional value. It is devoid of essential vitamins, minerals, and fatty acids. Its high level of processing means it has a high glycemic index, which can cause rapid spikes in blood sugar levels. This is generally undesirable in a ketogenic diet, as it can lead to an increased risk of cardiovascular disease, insulin resistance, type 2 diabetes, and excess abdominal fat.
The glycemic index is a system of classifying foods based on how much they raise blood glucose levels. Foods with a high glycemic index, such as cornstarch, are rapidly digested and absorbed, resulting in quick spikes in blood sugar. On the other hand, foods with a lower glycemic index are digested more slowly, leading to a gradual rise in blood sugar levels.
Cornstarch is a staple ingredient in many recipes, often used as a thickening agent. However, its ultra-processed nature and lack of nutritional benefits make it a poor choice for those following a ketogenic diet. The ketogenic diet is a low-carbohydrate, high-fat diet that aims to put the body into a state of ketosis, where fat is burned for energy instead of carbohydrates. This diet has been shown to have benefits such as reducing insulin levels and blood sugar.
While cornstarch may be convenient and commonly used, its ultra-processed nature and high glycemic index make it a food item that can quickly derail keto goals. Therefore, when following a ketogenic diet, it is best to avoid cornstarch and opt for low-carb alternatives that will support ketosis and provide additional health benefits.

It has a high glycemic index
Cornstarch is not recommended for a ketogenic diet because it has a high glycemic index. The glycemic index (GI) is a value assigned to foods based on how much they increase blood glucose levels. Foods with a high GI are rapidly digested and absorbed, leading to quick spikes in blood sugar levels, which is generally undesirable in a ketogenic diet. Cornstarch has a glycemic index of 85, which is considered high. This means that consuming cornstarch can cause a rapid increase in blood sugar levels, which is not suitable for a low-carb diet like the ketogenic diet.
The ketogenic diet is a low-carbohydrate, high-fat diet that aims to put the body into a state of ketosis, where it burns fat for energy instead of carbohydrates. This diet has been shown to reduce insulin levels and blood sugar in the body. Cornstarch, being high in carbohydrates, can quickly derail keto goals and prevent the body from entering or maintaining ketosis. A single tablespoon of cornstarch contains approximately seven grams of carbohydrates, which is already a significant contribution to the daily carb limit on a strict keto diet.
Furthermore, cornstarch is highly processed and offers minimal nutritional value. It is stripped of essential vitamins, minerals, and fatty acids during processing, and its low fibre content further makes it unsuitable for a keto diet. The lack of fibre in cornstarch can contribute to digestive issues and impact the absorption of other nutrients. Chronically elevated blood sugar levels, known as hyperglycemia, caused by high-glycemic foods like cornstarch, are linked to an increased risk of cardiovascular disease, insulin resistance, type 2 diabetes, and excess abdominal fat. Therefore, it is crucial to limit the consumption of high-glycemic foods like cornstarch when following a ketogenic diet.
However, it is important to note that some people may still include small amounts of cornstarch in their keto diet, especially when used as a thickening agent in small quantities. While it may not significantly impact ketosis, it is still advisable to opt for keto-friendly alternatives with lower glycemic indexes to maintain the desired blood sugar balance. These alternatives include almond flour, coconut flour, chia seeds, xanthan gum, and glucomannan, which offer similar textural properties without the high carb content and adverse health effects.

It has minimal nutritional value
Cornstarch is not keto-friendly as it is ultra-processed and high in carbohydrates, which can quickly hinder ketogenic goals. The ketogenic diet is a low-carbohydrate, high-fat diet intended to put the body in a metabolic state of ketosis. Cornstarch has a high glycemic index, which means it is quickly digested and absorbed, leading to rapid spikes in blood sugar levels. This is generally undesirable in a ketogenic diet.
Cornstarch has minimal nutritional value as it is stripped of essential vitamins, minerals, and fatty acids during its extensive processing. It offers no vitamin A, vitamin C, vitamin D, vitamin B12, or vitamin B6. It also contains no amino acids.
The high carbohydrate content of cornstarch is problematic for a ketogenic diet, which typically limits total daily carbohydrate intake to between 20 and 50 grams. Cornstarch has a significant amount of net carbs, with 90.37 grams of net carbs per 100 grams. This means that even a small portion of cornstarch can exceed the daily carb limit on a strict keto diet.
The minimal nutritional benefits of cornstarch, combined with its lack of beneficial vitamins, proteins, and significant dietary fiber, further limit its utility on a keto diet. Therefore, while cornstarch may provide some extra calories, its advantages in terms of health benefits end there.
There are several low-carb alternatives to cornstarch that are more suitable for a ketogenic diet, such as almond flour, coconut flour, and flax meal. These alternatives can help achieve weight loss and health goals while maintaining ketosis.

There are keto-friendly alternatives
Cornstarch is not keto-friendly as it is ultra-processed, high in carbs, and can cause a rapid increase in blood sugar levels. However, there are several keto-friendly alternatives that can be used as thickeners in soups, gravies, sauces, and baked goods. Here are some keto-friendly substitutes for cornstarch:
Almond Flour or Almond Meal
Almond flour or almond meal can provide the same texture and consistency as cornstarch without the high carb count or adverse health effects. It contains beneficial vitamins and minerals, including vitamin E, iron, manganese, magnesium, potassium, and calcium. It has also been shown to improve heart health and decrease the risk of cancer cell formation.
Xanthan Gum
Xanthan gum is commonly used as a replacement for corn starch as it is an excellent thickener. It is often found in the ingredient list for gluten-free foods, salad dressings, and ice creams. It helps keep sauces and soups thick without adding carbs. It is also a good egg replacer for vegan keto followers.
Glucomannan
Glucomannan is a type of dietary fiber derived from the root of the konjac plant. It is tasteless and can be added to various dishes without changing their flavour. Its high-fibre content and low-calorie count make it beneficial for weight loss and appetite management.
Eggs
Eggs are a staple in many keto diets as they are incredibly low in net carbs and high in fat and protein. They can be used as a thickening agent, but caution must be exercised to avoid ending up with scrambled eggs.
Gelatin
Gelatin has zero net carbs and is rich in amino acids that improve joint and bone health and enhance the appearance of skin and hair. It can be used as a substitute for cornstarch in puddings, along with alternative sweeteners such as erythritol, stevia, or monk fruit.
Other keto-friendly alternatives to cornstarch include chia seeds, ground flaxseed, arrowroot, and guar gum.
