Carb Counting: Eating Too Few Carbs On Keto

The ketogenic diet is a popular, very low-carb approach to eating that has helped many people lose weight. However, it is easy to make mistakes when starting a low-carb diet, and eating too few carbohydrates can have negative consequences for your health. While the exact amount of carbs a person can eat and remain in ketosis varies, it is generally recommended that people eat under 50 grams of carbs per day to reach ketosis. Eating too few carbs can lead to constipation, fatigue, weakness, brain fog, and mood changes, among other side effects. To avoid these issues, it is important to be mindful of your carb intake and ensure you are getting enough nutrients from other sources.

Eating too much protein can prevent ketosis

While on a keto diet, it is important to be mindful of your protein intake. Although the primary focus of the keto diet is to restrict carbohydrates and eat plenty of fat, protein intake also plays a crucial role in achieving ketosis. Eating too much protein may impair ketone production and prevent your body from reaching a state of ketosis.

When protein is digested, it triggers the release of insulin and glucagon, two hormones that regulate energy. Insulin stimulates the uptake of sugar into cells and reduces the breakdown and release of fat from fat cells, while glucagon triggers glycogen breakdown, fat burning, and the production of ketones. The ratio of insulin to glucagon released depends on factors such as the macronutrient makeup of the diet, gender, activity levels, and the presence of diabetes.

For keto dieters, the key effect of these hormones is their opposing influence on ketone production. Insulin decreases ketone production, while glucagon stimulates it. If insulin levels are higher than glucagon, ketone production will be reduced, and the body may be "kicked out" of ketosis. This is more likely to occur in individuals with type 2 diabetes, as they tend to experience a significant increase in insulin levels after consuming protein.

Research suggests that the amino acid alanine may also suppress ketone production. Additionally, protein has a moderate insulin-stimulating effect, and increased insulin levels can lead to decreased fatty oxidation and inhibited ketone production. Therefore, it is important for keto dieters to monitor their protein intake and not exceed their personal tolerance to maintain ketosis.

To find your ideal protein intake while on a keto diet, you can manually calculate your keto macros or use a keto calculator. Gradually increase your protein intake while monitoring your ketone levels to determine your upper limit for remaining in ketosis. As a general guideline, a standard keto diet recommends 30% of your daily calories come from protein, which is typically between 0.7-1 gram of protein per pound of body weight. However, this may vary depending on activity levels, age, and health status.

The body converts protein to glucose if you don't eat carbs

The body can convert protein to glucose when there is a low supply of carbs in the diet. This process is called gluconeogenesis. It is a metabolic pathway that helps the body maintain homeostasis by keeping blood sugar levels stable.

When there are not enough carbohydrates to meet the body's glucose needs, it will form glucose from other sources, such as fat and protein. The liver plays a vital role in this process, as it can convert glycogen (stored sugar bundles) to glucose. Additionally, the liver can also synthesize glucose from amino acids (which are the building blocks of protein) and glycerol from fat.

Gluconeogenesis is not a cause for concern. It is an ingenious mechanism designed to protect the body and maintain a state of equilibrium. In fact, the relative consistency of blood sugar is an example of the body's pathway to remain in a homeostatic state. As Colette Heimowitz, Vice President of Nutrition & Education at Atkins Nutritionals, Inc., explains, "You need to keep your protein breakdown synthesis greater than or equal to your protein breakdown. This is especially true if you're working out and trying to build muscle."

However, excessive protein intake can lead to gluconeogenesis, and this has led to some people in the ketogenic community eating too few calories from protein. According to Heimowitz, the focus should be on optimal protein intake rather than fearing the conversion of protein to glucose. Optimal protein intake depends on various factors, including activity level, weight, height, gender, body composition, and stress and inflammation levels in the body. In general, women should aim for 4-6 oz of protein per meal, while men should aim for 8 oz.

When following a low-carb diet, it is important to ensure adequate protein intake to maintain lean body mass and support muscle growth, especially if you are physically active. By understanding gluconeogenesis and optimal protein intake, individuals can make informed decisions about their diet and avoid common pitfalls associated with low-carb diets.

A low-carb diet must be high in fat to provide energy and nutrition

When it comes to the keto diet, it is important to understand that simply reducing carbohydrate intake is not enough to achieve the desired metabolic benefits and weight loss. A well-formulated low-carb diet should be high in fat and moderate in protein. This is because, when you remove carbohydrates as a primary energy source, you need to replace them with something else to avoid hunger and inadequate nutrition.

Fats play a crucial role in a low-carb or ketogenic diet. They provide a significant portion of the total calories, with some individuals deriving up to 70% of their calories from healthy fats. This high-fat intake is essential to ensure sufficient energy and nutrient intake.

To achieve this, it is recommended to choose fatty cuts of meat and generously add healthy fats to meals. Monounsaturated and omega-3 fats are excellent choices, while trans fats should be avoided. This approach ensures that the body receives the necessary energy and nutrients while still adhering to the low-carbohydrate framework of the keto diet.

It is worth noting that the "25 grams of carbs per day" recommendation is based on the glucose needs of the brain. However, as the body adapts to ketosis, the brain starts using ketones for fuel, reducing the need for glucose. This shift means that the body can convert less protein into glucose, optimizing protein's role in muscle development and repair.

In summary, a low-carb diet, such as keto, must be high in fat to provide the body with sufficient energy and essential nutrients. This high-fat approach ensures that individuals can sustain their energy levels and nutritional requirements while still reaping the benefits of reduced carbohydrate consumption.

Low-carb diets can lead to mild sodium deficiency

The symptoms of mild sodium deficiency can include lightheadedness, fatigue, headaches, leg cramps, and constipation. To avoid this, it is recommended that people on low-carb diets add more sodium to their food by salting their meals. If this doesn't help, drinking a cup of broth every day could be a solution. Another option is to use a salt-based electrolyte supplement, which can be added to water.

It is important to note that consuming too much sodium can be dangerous for your health, especially as it is a risk factor for high blood pressure. The Food and Drug Administration has set the Daily Value for sodium at no more than 2,300 mg per day.

In addition, the kidneys are usually effective at regulating electrolyte levels and maintaining the body's chemical balance after adjusting to a low-carb diet. Therefore, mild sodium deficiency is not a common issue for people eating a typical Western diet.

It can take several days to adapt to a low-carb diet

When starting a low-carb diet, it is important to be aware that it can take some time for your body to adjust to the new way of eating. This adjustment period is a normal part of the process and is known as the "keto flu".

The "keto flu" typically lasts for a few days, during which you may experience some unpleasant symptoms such as feeling under the weather. This is because your body is shifting from burning carbs to burning fat for energy. This transition can take a few days to fully take effect, and it may take even longer for your body to reach full adaptation, which can take several weeks.

During this adjustment period, it is important to be patient and not give up on your diet too soon. It is also a good idea to consult a dietitian or healthcare professional before starting any new diet, to ensure that it is safe and appropriate for your individual needs.

To help ease the transition, make sure you are consuming enough healthy fats and adequate protein. This will help ensure that your body has the energy and nutrition it needs during this period of adjustment. Additionally, staying hydrated and getting enough rest can also help support your body during this time.

While it may take some time for your body to adapt to a low-carb diet, it is important to remember that this is a normal part of the process. By being patient and listening to your body, you can successfully navigate the adjustment period and work towards achieving your health and wellness goals.
