Keto Diet: Does Eating Enough Fat Matter?

The keto diet is a low-carb, high-fat diet. The basic principle is that by reducing carbohydrates, the body enters a state of ketosis, where it burns stored fat for energy. However, this doesn't mean that all fats are good. The keto diet recommends a high intake of healthy fats, such as those found in avocados, nuts, seeds, olive oil, and oily fish.

If you don't eat enough fat on the keto diet, you may experience negative side effects. Firstly, you may feel hungrier, as fat is satiating and keeps you feeling fuller for longer. A lack of fat in the diet can also lead to digestive issues like nausea, constipation, and diarrhea. In addition, not consuming enough fat can impact your energy levels, leaving you feeling tired and lethargic. Finally, not getting enough fat can lead to nutrient deficiencies, as vitamins A, D, E, and K are fat-soluble, and your body needs dietary fat to absorb them properly.

Fat is fuel

Fat is a critical component of the ketogenic diet, and for good reason—it is fuel for the body. When you're on keto, fat takes centre stage as the primary source of energy, replacing carbohydrates. This shift in fuel source is what sets keto apart from other diets and is key to achieving a state of ketosis, where the body burns fat for energy instead of glucose.

Why Fat Matters

The keto diet is typically comprised of about 70-80% fat, 15-20% protein, and only 5-10% carbohydrates. This high-fat composition is intentional and necessary to keep the body in ketosis. If the balance is off, with too little fat and too much protein or carbs, the body won't reap the full benefits of keto, such as weight loss and improved blood sugar control.

Benefits of Eating Enough Fat

Eating enough fat on keto is not just about maintaining ketosis. It has several other advantages:

• Satiety and reduced cravings: Dietary fat keeps you feeling fuller for longer, reducing hunger and cravings.
• Improved energy levels: Fat provides lasting energy and helps combat fatigue.
• Better digestion: Not consuming enough fat can lead to digestive issues like nausea, constipation, and diarrhea.
• Nutrient absorption: Vitamins A, D, E, and K are fat-soluble, meaning they need dietary fat to be properly absorbed.
• Healthy cholesterol: Eating healthy fats can help lower low-density lipoprotein (LDL) levels, which is the "bad" cholesterol.

How to Get Enough Fat

Now that we've established the importance of fat on keto, here are some tips to ensure you're getting enough:

• Choose full-fat foods: Opt for full-fat dairy, fatty fish, and whole eggs instead of low-fat options.
• Cook with fat: Use fats like olive oil, butter, or coconut oil for cooking to easily increase your fat intake.
• Add fat to drinks: Try adding butter or coconut oil to your coffee, or creamer and whipped cream to tea.
• Snack on high-fat foods: Nuts, cheeses, and hard-boiled eggs are great snack options that provide healthy fats.
• Top meals with fat: Add high-fat garnishes like nuts, seeds, avocado, or cheese to your meals for an extra boost of fat.

Consequences of Not Eating Enough Fat

What happens if you don't get enough fat on keto? Here are some potential issues:

• Hunger and cravings: Without enough fat, you're more likely to feel hungry and crave food, making it challenging to stick to the diet.
• Metabolic slowdown: Inadequate fat intake can lead to a decrease in overall calories, causing your metabolism to slow down.
• Nutrient deficiencies: Not consuming enough fat can worsen vitamin deficiencies, especially for fat-soluble vitamins A, D, E, and K.
• Digestive issues: Low fat intake can result in digestive problems like nausea, constipation, and diarrhea.
• Protein poisoning: Consuming too much protein and not enough fat can lead to a dangerous condition called protein poisoning, which includes symptoms like nausea, hyperinsulinemia, hyperammonemia, and diarrhea.

In conclusion, fat is indeed fuel, especially on the keto diet. Eating enough healthy fats is crucial to maintaining ketosis, keeping you energised and satiated, and preventing potential health issues. So, embrace those avocados, olive oil, nuts, and other healthy fat sources to keep your body fuelled and functioning optimally on keto!

Protein poisoning

The liver and kidneys play a crucial role in protein metabolism. Consuming excessive amounts of protein can lead to increased levels of ammonia, urea, and amino acids in the blood, putting the body at risk. Protein poisoning can be fatal due to these elevated levels.

Symptoms of protein poisoning include increased hunger and food cravings. Treatment for protein poisoning is straightforward and involves reducing protein intake while increasing the consumption of healthy fats and carbohydrates. It is recommended to maintain a balanced intake of macronutrients to ensure optimal health.

Causes of Protein Poisoning

• Intake of protein-rich foods at odd hours
• Excessive consumption of protein supplements
• Poor gut health affecting the absorption of other vital nutrients

Prevention and Treatment

To prevent protein poisoning, it is important to maintain a balanced diet that includes all three macronutrients. The recommended daily allowance (RDA) for protein is 0.8 grams per kilogram of body weight. However, protein needs can vary depending on physical activity levels and other factors.

Treatment for protein poisoning focuses on restoring balance to the body's macronutrient intake. This involves reducing protein intake to no more than 2.0 grams per kilogram of body weight while increasing the consumption of healthy fats and carbohydrates. Additionally, increasing fibre intake and incorporating essential vitamins and minerals can promote overall well-being.

Keto Diet and Protein Poisoning

The keto diet, a popular low-carb, high-fat diet, typically includes adequate amounts of fat and protein, making protein poisoning unlikely. However, it is important to ensure a proper balance of macronutrients, even on a keto diet, to maintain overall health and avoid potential issues like protein poisoning.

Hunger and cravings

The keto diet is a low-carb, high-fat diet. It works by cutting out carbs and replacing them with fats, which then become the body's primary source of energy. This shift in energy source is known as ketosis.

When you start the keto diet, you will likely experience hunger and cravings, especially in the early stages. This is because your body is adjusting to a new fuel source, and it takes time for your body to adapt.

• Reduced Calorie Intake: If you are not getting enough calories from fats and proteins, you may feel hungry. This is because your body is not getting enough energy to function optimally.
• Psychological Factors: The environment, such as seeing or smelling delicious foods, can stimulate cravings even if your nutritional needs are met.
• Hormonal Changes: Hormonal shifts, especially during the luteal stage of menstruation, can lead to sweet cravings.
• Stress and Emotional Factors: Stress, sadness, loneliness, and boredom can trigger a desire to eat, sometimes mistaken for hunger.
• Habit: Eating according to a routine or in response to external cues, such as seeing tempting foods, can also lead to increased hunger and cravings.

Tips to Manage Hunger and Cravings on Keto:

• Understand the Basics: Ensure you clearly understand the keto diet and its requirements. This includes knowing which foods to eat and which to avoid.
• Gradual Transition: Instead of abruptly switching to keto, gradually reduce your carb intake. Start by cutting out refined sugary foods and refined carbs, then move on to natural high-carb foods. This gives your body time to adjust to the new diet.
• Increase Healthy Fat Intake: Eating more healthy fats, such as avocado, nuts, and fatty fish, will help you feel fuller for longer and curb cravings.
• Prioritize Protein: Include sufficient protein in your meals to lower hunger hormones and increase fullness hormones. Animal-based protein sources like eggs, meat, and fish are ideal.
• Eat Low-Carb Vegetables: Include low-carb, fiber-filled vegetables like kale, spinach, and broccoli. Fiber adds bulk to your meals without increasing calories, helping you feel satisfied.
• Stay Hydrated: Thirst can sometimes be mistaken for hunger. Drink plenty of water and consider adding electrolytes to your water to meet your body's increased needs on keto.
• Get Enough Sleep: Sleep deprivation can increase your hunger hormone, ghrelin, making it harder to resist cravings. Aim for 7-9 hours of quality sleep each night.
• Manage Stress: Stress can trigger emotional eating. Find healthy ways to manage stress, such as meditation, exercise, or social activities.
• Period Cravings: Hormonal changes during the menstrual cycle can increase cravings. To manage this, increase your calorie intake by 200-300 calories per day, focusing on healthy fats and proteins.
• Avoid Artificial Sweeteners: Artificial sweeteners can activate the brain's reward centres, making it difficult to control cravings.
• Identify Triggers: Keep a food diary to identify specific triggers for your cravings. This can help you develop strategies to manage them effectively.

Nutrient deficiencies

Additionally, a keto diet may be lower in fibre because whole grains are eliminated, which can lead to constipation. A high-fat diet may also increase the risk of ketoacidosis for those with type-2 diabetes.

Furthermore, a keto diet may be deficient in the following vitamins and minerals: vitamin B1, vitamin B6, vitamin B7, vitamin B12, calcium, iron, magnesium, and phosphorus. These nutrients are essential for the body to function properly, and they cannot be produced by the body, so they must be obtained from food or supplements.

Therefore, it is important to be aware of any nutrient deficiencies before starting a keto diet and to include a variety of nutrient-dense foods or supplements to avoid potential health risks.

Fat is filling

Fat is an essential part of a healthy diet, and it has a range of benefits for the body and brain. Eating fat helps you feel full and satisfied for longer, curbing cravings and providing lasting energy.

Why Fat is Filling

Fat is a macronutrient that plays a vital role in numerous bodily functions, including cell growth and regeneration, brain growth and development, and digestion.

Fat is also responsible for keeping us full and satisfied for longer periods of time. This is because longer-chain fats are metabolized more slowly, keeping you feeling full. Short-chain fats, on the other hand, are used for energy and metabolized quickly, so they don't have the same satiating effect.

The Benefits of Eating Fat

In addition to making you feel full, eating healthy fats has a range of other benefits:

• Healthy fats are a good source of essential fatty acids, which your body needs but cannot produce itself.
• Eating fat can help lower your low-density lipoprotein levels, which is the "bad" cholesterol in your body.
• Fat-soluble vitamins A, D, E, and K need dietary fat to be properly absorbed. These vitamins play a crucial role in important body functions, including hormone signaling, gut health, and immune function.

Sources of Healthy Fats

Some good sources of healthy fats include:

• Avocados and avocado oil
• Nuts and seeds (and their butters)
• Olives and olive oil
• Oily fish, such as tuna, anchovies, and salmon
• Full-fat dairy products, such as Greek yogurt, cheese, and butter
• Eggs
• Tofu and edamame
• Dark chocolate

The Right Amount of Fat

While fat is an essential part of a healthy diet, it's important to eat the right amount. On the keto diet, for example, about 70-80% of your daily calories should come from fat. However, it's important to note that extremely high-fat diets, like keto, are not recommended for everyone and should be undertaken with caution and medical advice.

Incorporating healthy fats into your diet is a great way to stay full and satisfied while also promoting a range of health benefits. Just be sure to eat the right types of fats and avoid excessive consumption of saturated and trans fats, which can have negative health effects.
