Dirty Keto: Is It Really Effective?

The ketogenic diet, or keto, is a high-fat, low-carb diet that has become popular for weight loss and its proposed health benefits. There are two versions of the keto diet: clean keto and dirty keto. Dirty keto is a spin on the traditional keto diet that focuses on weight loss instead of overall health. It involves decreasing your carbs and increasing your fats intake, but without any considerations for the quality of food you consume. It allows processed and fast foods, as well as prepackaged snacks. While dirty keto can be an effective way to lose weight, it may also lead to some adverse health effects.

Dirty keto can lead to micronutrient deficiencies

Dirty keto is a variation of the traditional keto diet, sometimes referred to as "lazy keto". It is a ketogenic diet that ignores food quality and focuses only on the macronutrient breakdown. While a dirty keto diet can help you lose weight, it can also lead to micronutrient deficiencies, which can have adverse effects on your health.

Micronutrient Deficiencies on a Dirty Keto Diet

The keto diet is a high-fat, low-carb diet that restricts carbohydrates and promotes the consumption of fats and small amounts of protein. This shift in macronutrients forces the body to use fat as its primary source of energy, triggering a process called ketosis. A dirty keto diet still follows the main rule of keto dieting: keeping carbs low to keep insulin levels low, which facilitates the breakdown and release of stored body fat. However, a dirty keto diet often includes ultra-processed foods like vegetable oils, artificial sweeteners, and processed meats, which are low in nutrients like vitamins, minerals, and fiber.

If your keto plate is devoid of low-carb vegetables, you are likely not getting enough vitamins and minerals. Non-starchy veggies like spinach, kale, asparagus, broccoli, and cabbage are some of the most nutrient-dense foods around. These plant foods are rich in folate, vitamin A, vitamin C, calcium, magnesium, and potassium, which are crucial for energy production, nervous system health, cardiovascular support, and reproductive health.

For example, consider folate (vitamin B9). The best natural sources of folate are lentils, but they have too many carbs to be keto-friendly. This leaves keto dieters with spinach, asparagus, beef liver, and broccoli, which are often spurned on a dirty keto diet.

Health Risks of Micronutrient Deficiencies

Micronutrient deficiencies can lead to serious health problems. For instance, thiamin (vitamin B1) deficiency can lead to neurological problems such as beriberi and Wernicke-Korsakoff syndrome. Calcium deficiency can cause neuromuscular and cardiovascular issues such as tetany, rickets, osteomalacia, and osteoporosis.

Avoiding Micronutrient Deficiencies on a Keto Diet

To avoid micronutrient deficiencies on a keto diet, it is important to focus on whole foods, healthy fats, and non-starchy vegetables. Eating clean keto means using healthy fats like olive oil, avocados, coconut oil, butter, and ghee; largely avoiding vegetable oils and processed meats; filling your plate with low-carb vegetables; and eating a wide spectrum of real foods for optimal micronutrient and macronutrient intakes.

It can cause inflammation

Dirty keto is a ketogenic diet that focuses on macronutrient ratios without considering the quality of the food sources. It involves consuming ultra-processed foods like vegetable oils, artificial sweeteners, and processed meats, which are high in inflammatory omega-6 polyunsaturated fats. These fats, when consumed in excess, are believed to contribute to obesity and create inflammatory conditions that promote fat storage.

Vegetable oils, commonly used in dirty keto, are also unstable at high heat, creating oxidized lipids that have been linked to heart disease. Additionally, the lack of low-carb vegetables in a dirty keto diet can lead to micronutrient deficiencies, particularly in folate, which is crucial for energy production, nervous system health, cardiovascular support, and reproductive health.

Dirty keto can also negatively impact digestive health by causing constipation due to the lack of fiber in the diet. Fiber is important for bowel regularity and promoting a healthy gut microbiome, which has anti-inflammatory benefits.

The consumption of fast and processed foods on a dirty keto diet can lead to micronutrient deficiencies, increased inflammation, and a higher risk of adverse health effects.

It may not be cheaper than clean keto

Dirty keto may not be cheaper than clean keto. While it is often claimed that dirty keto is more affordable than clean keto, this may not be the case. Consuming prepackaged keto foods and products can be expensive.

Dirty keto is a more flexible and convenient approach, allowing processed and fast foods, as well as prepackaged snacks. It does not consider the quality of food, focusing only on the macronutrient ratio. On the other hand, clean keto emphasises locally sourced, high-quality, and healthy foods, which may be more expensive.

Dirty keto may be more appealing to those on a busy schedule as it requires less time-intensive food preparation. However, it is important to note that the convenience of prepackaged keto options comes at a cost. These products are designed to fit within the keto diet framework and often carry a premium price tag.

In summary, while dirty keto may offer some cost savings by including more affordable, highly processed foods, the overall expense may not be significantly lower than clean keto when factoring in the cost of specialised keto products.

It can cause vitamin and mineral deficiencies

Dirty keto is a ketogenic diet that focuses on macronutrient ratios (carbohydrates, proteins, and fats) rather than the quality of the food consumed. It involves decreasing your carbs and increasing your fats intake, often through the consumption of processed and fast foods. While this approach can help you lose weight and burn body fat, it can also lead to vitamin and mineral deficiencies, which can have adverse effects on your health.

Dirty keto is associated with a higher risk of micronutrient deficiencies, including vitamins B1, B5, B7, B9, B12, D, and E, as well as minerals like calcium, magnesium, manganese, potassium, and sodium. These deficiencies can occur due to the lower consumption of micronutrient-rich foods such as fruits, vegetables, grains, and legumes.

For example, non-starchy vegetables like spinach, kale, asparagus, broccoli, and cabbage are excellent sources of folate (B9), a crucial vitamin for energy production, nervous system health, cardiovascular support, and reproductive health. However, since dirty keto often excludes these vegetables, it can lead to a deficiency in this vital nutrient.

Similarly, dirty keto may also result in a deficiency of vitamin B7 (biotin), which is essential for maintaining healthy hair, skin, and eyes. Foods like liver, egg yolks, meat, and salmon, which are rich in vitamin B7, may be consumed less frequently on a dirty keto diet.

In addition to vitamin deficiencies, dirty keto can also lead to mineral deficiencies. For instance, calcium is the most abundant divalent cation in the body, playing a crucial role in bone and teeth structure, muscle contraction, blood clotting, and enzyme activation. A lack of calcium-rich foods, such as dairy products and certain vegetables, can lead to calcium deficiency, resulting in neuromuscular and cardiovascular issues.

The potential for micronutrient deficiency on a dirty keto diet is significant, and prolonged adherence to this diet may lead to serious adverse health effects. Therefore, it is essential to prioritize the consumption of nutrient-dense, whole foods and consider supplementation to avoid vitamin and mineral deficiencies.

It can lead to weight gain post-diet

Dirty keto is a low-carb, ketogenic diet that ignores food quality. It focuses on the ratio of macronutrients (carbohydrates, proteins, and fats) consumed, rather than the quality of the food. This means that people on the dirty keto diet can eat processed foods, fast foods, and prepackaged snacks, as long as they fit within the macronutrient ratio.

Dirty keto can lead to weight gain post-diet due to the following reasons:

• Inflammatory vegetable oils: Dirty keto diets tend to include large amounts of vegetable oils such as soybean oil, safflower oil, sunflower oil, and canola oil. These oils are high in omega-6 polyunsaturated fats, which have been linked to obesity and inflammatory conditions that drive fat storage.
• Micronutrient deficiency: Dirty keto diets often lack low-carb vegetables, which are rich sources of vitamins and minerals. This can lead to deficiencies in folate, vitamin A, vitamin C, calcium, magnesium, and potassium, which are crucial for energy production, nervous system health, cardiovascular health, and reproductive health.
• Fiber deficiency: Avoiding fiber can lead to digestive issues such as constipation and negatively impact the gut microbiome. Fiber is important for bowel regularity and also serves as food for gut bacteria, which produce anti-inflammatory compounds.
• Increased endotoxin levels: Consuming fast and processed foods can lead to increased endotoxin levels, which can contribute to weight gain.
• Vitamin and mineral deficiencies: In addition to micronutrient deficiencies, dirty keto diets can also lead to vitamin and mineral deficiencies, which can impact overall health and weight management.

While dirty keto may lead to initial weight loss, these potential deficiencies and health issues can hinder long-term weight management and contribute to weight gain post-diet.
