Starch In Potatoes: Keto-Friendly Or Not?

The keto diet is a popular weight-loss strategy that involves putting your body into a state of ketosis, where it burns fat for fuel instead of carbohydrates. To achieve this, it's essential to limit your carbohydrate intake, and one type of carbohydrate that often comes under scrutiny is starch. So, is potato starch bad for keto? The short answer is yes — potato starch is high in net carbs and can quickly kick you out of ketosis, even in small amounts. However, it's important to distinguish between regular potato starch and resistant potato starch, which may offer some potential health benefits, even on a keto diet.

Potato starch is high in net carbs, with 77.5g per 100g serving

Potato starch is not keto-friendly because it is high in net carbs. A 100g serving contains 77.5g of net carbs, which is significantly more than the recommended daily intake of 20-30g to stay in ketosis. This means that even a small serving of potato starch could kick you out of ketosis.

The ideal macronutrient ratio for keto is 70% fat, 20-25% protein, and 5-10% carbs, so the majority of foods consumed on a keto diet should be low in carbs and high in fats. Avocado, salmon, and ghee are examples of foods that fit this profile.

Potato starch, on the other hand, is both high in carbs and low in fats. It is composed almost entirely of carbohydrates, which break down into glucose and cause spikes in blood sugar and insulin levels. This inhibits the breakdown of body fat and promotes fat gain, making it a poor choice for those looking to lose weight.

While potato starch is minimally processed, it is not a good fit for keto due to its high carb content. To achieve healthy weight loss on keto, it is important to consider both the macros and ingredients of your foods.

It is not keto-friendly as it may kick you out of ketosis

Potato starch is not keto-friendly as it is very high in net carbs, containing 83.3 grams of carbohydrates per 100 grams of potato starch. This is in direct opposition to the keto diet's recommended macronutrient ratio of 70% fat, 20-25% protein, and only 5-10% carbs.

To stay in ketosis, it is recommended to limit your net carb consumption to 20-30 grams per day. Even a small serving of potato starch can kick you out of ketosis due to its high carb content.

Potato starch is a refined carbohydrate that causes a spike in blood sugar and insulin levels, leading to increased body fat and inhibiting weight loss. This is contrary to the goal of the keto diet, which aims to keep blood sugar and insulin levels low to trigger fat-burning mode.

Therefore, it is essential for those following a keto diet to avoid potato starch and opt for alternative low-carb, high-fat options such as avocado, salmon, and ghee.

It is worth noting that some sources mention resistant starch, which is a type of starch that resists digestion and acts more like a fibre. Resistant starch is found in foods like green bananas, plantains, cooked and cooled potatoes, and rice. While resistant starch is technically a carbohydrate, it is not digested and converted into glucose, making it keto-friendly. However, it is important to be cautious as these foods can also contain digestive carbohydrates that will convert to glucose and potentially kick you out of ketosis.

It is a refined carbohydrate that increases blood sugar and insulin levels

Potato starch is a refined carbohydrate that sends blood sugar and insulin levels soaring. It is made up of multiple sugars, which are broken down by the liver into simple sugars, such as glucose. This process keeps blood sugar and insulin levels elevated, preventing the breakdown of body fat and promoting fat gain.

When blood sugar is high, the body does not burn fat. Instead, it stores it. This is because high blood sugar levels cause an increase in insulin, which sends a message to the body to store fat. In addition, the liver converts excess glucose into glycogen, which is then stored in the liver and muscles. This stored glycogen can be converted back into glucose and used as energy when blood sugar levels drop. As a result, the body does not need to burn fat for energy, and weight loss is hindered.

The body can only enter a state of ketosis when insulin levels are low. In this state, the body burns fat for energy instead of carbohydrates. However, when starch is constantly introduced into the digestive system, blood sugar and insulin levels remain high, preventing ketosis.

Potato starch is also highly processed, undergoing multiple shifts of industrial processing to separate the starch from other nutrients and fiber. This results in a product that is purely concentrated sugars, devoid of any fiber or other nutrients that could slow the absorption of glucose.

Therefore, potato starch is not suitable for low-carb diets such as the keto diet due to its significant impact on blood sugar and insulin levels.

It is not suitable for weight loss as it promotes fat gain

Potato starch is not suitable for weight loss as it promotes fat gain. This is because it is a refined carbohydrate that causes a spike in blood sugar and insulin levels. In turn, this inhibits the breakdown of body fat and promotes fat gain.

Potato starch is a type of starch derived from potatoes. Starch is a cluster of sugar molecules and is the primary way in which plants store energy. It is made up of molecules called polysaccharides, or chains of sugar molecules. When starch is digested, it is broken down into glucose, which raises blood sugar levels.

The keto diet involves cutting carbs from your diet. This is because limiting carbs keeps blood sugar low, which in turn keeps the hormone insulin low. When insulin is low, the body sends a signal to its cells to start breaking down body fat and sending fatty acids to the muscles for energy and to the liver for ketone production.

However, if you are constantly introducing glucose into your digestive system by eating starch, blood sugar and insulin levels never drop low enough to send the fat-burning signal. Instead, high insulin levels send the message to store fat.

Potato starch is composed almost entirely of carbohydrates and is, therefore, not suitable for low-carb diets such as the keto diet. It is also highly processed and separated from other nutrients and fibre, leaving only concentrated multiple sugars.

Therefore, potato starch is not suitable for weight loss as it promotes fat gain by inhibiting the breakdown of body fat and sending the body a signal to store fat.

It is gluten-free but contains lectins

Potato starch is a refined, industrially processed food that is high in carbohydrates. It is derived from potatoes and often used as a thickener for sauces, soups, and stews, as well as a binder in baking. While it is gluten-free, it does contain lectins, which are sticky proteins that plants use as toxins to defend themselves against predators.

Lectins can have negative effects on the intestines, but they also have some potential health benefits. For example, they can improve metabolic function by reducing blood sugar spikes and improving insulin sensitivity. Additionally, lectins have been shown to lower total and LDL cholesterol levels, which can be beneficial for those who experience large jumps in cholesterol numbers while on a keto diet.

However, the potential downsides of lectins should also be considered. They can contribute to Small Intestinal Bacterial Overgrowth (SIBO) and create a mismatch of bacteria in the gut, which could negatively impact health. Most experts agree that a diverse bacteria population in the gut is preferable to having too much of any one type.

Therefore, while potato starch is gluten-free, the presence of lectins means that it should be consumed with caution. It is important to note that sweet potatoes do not contain lectins, so they may be a better option for those concerned about the potential negative effects of lectins.
