What is the Keto Diet? Advantages and Disadvantages

 

The keto diet is a popular approach for weight loss, controlling weight gain, enhancing health, and other benefits. However, not everyone practicing keto fully understands what it entails.

1. What is the Keto Diet?

Keto, short for "Keep Eating The Fat Off," is a diet that drastically reduces carb intake to minimal levels. Instead, it emphasizes increased fat consumption to provide the body with calories. In this diet, the body burns more energy from stored sources, mainly targeting fats and accumulated excess fat in the muscles.

Many people choose the keto diet for weight loss. There are various ways to follow a keto diet, but the common ratio is 25% protein, 70% fat, and only 5% carbs.

While the keto diet is suitable for most people, the following groups should consult a doctor to avoid potential health risks:

Breastfeeding women.

People with hypertension.

People with diabetes.

2. Benefits and Drawbacks of the Keto Diet

Reducing carbs and relying on fats for daily calories in the keto diet has several health benefits and drawbacks.

2.1. Benefits of the Keto Diet

The primary principle of the keto diet is to help the body shift from burning energy stored as carbs in the muscles to burning stored fats for energy, leading to effective weight loss. The high-fat meals also provide a sense of fullness, making it easier for individuals to adhere to the diet compared to other fat-restricted diets.

Weight and diabetes are interlinked; excessive body fat can impair energy metabolism, increase blood sugar levels, and reduce insulin function. The keto diet's fat-burning effect can reduce these risk factors, helping to prevent and manage diabetes.

The brain requires glucose for functioning. When carb intake is reduced, the liver produces glucose from proteins for the brain. This state can improve brain function in children with epilepsy and individuals with Alzheimer’s and Parkinson’s diseases.

2.2. Drawbacks of the Keto Diet

Many wonder if long-term keto dieting can impact health. Here are some potential disadvantages:

Muscle Development: Keto dieting may hinder muscle growth since the body uses stored fats and carbs for energy. Carbs are essential for muscle development, so strict carb control can affect muscle growth.

Discomfort: The body's energy metabolism changes, causing initial discomfort like fatigue, difficulty concentrating, and nausea. However, these symptoms often subside once the body adapts.

Digestive Issues: Limiting carbs can also reduce fiber intake, leading to digestive problems like constipation and bloating.

Muscle Soreness and Cramps: Reduced fruit and vegetable intake can lower calcium, potassium, magnesium, and vitamin levels, causing muscle soreness and cramps, especially in the calves.

Brain and Liver Function: Although beneficial for certain brain conditions, keto can sometimes cause energy deficits in the brain, leading to reduced mental clarity. This is more common in the initial stages or in those with liver issues.

Additionally, the liver works harder on a keto diet, metabolizing carbs and fats and increasing glycogen production for the brain. Excess fat intake can also lead to fatty liver if not managed properly.

Vitamin and Mineral Deficiency: Many on a keto diet experience deficiencies, which can be mitigated by supplementing magnesium, electrolytes, and fiber. This supplementation can also alleviate some keto diet side effects like insomnia, headaches, fatigue, constipation, and dizziness.

3. Sample Keto Meal Plan for Beginners 

You can diversify your daily keto meals based on the following standard menu:

• Breakfast: 2 fried eggs, 1 slice of salmon with avocado or olive oil.
• Morning Snack: Nuts, such as almonds.
• Lunch: Bell peppers, chicken breast, salad with fatty oil.
• Afternoon Snack: Cheese.
• Dinner: Beef, mushrooms, leafy greens.
• Foods to vary in your keto meals include:
• Meats: Beef, chicken, bacon, sausages.
• Fatty Fish: Tuna, salmon, mackerel.
• Nuts: Walnuts, pumpkin seeds, almonds, flaxseeds, chia seeds (best as snacks for added energy).
• Cheese: Unprocessed varieties like mozzarella, cream, cheddar.
• Low-carb Vegetables: Tomatoes, leafy greens, bell peppers, onions.
• Boiled eggs, berries, dark chocolate.

Foods to limit include high-carb items like unhealthy fats, grains, starches, beans, sugary foods, and alcohol. While most fruits aren't keto-friendly, avocados, blueberries, and strawberries can be included.

Consistency and seriousness are crucial for achieving health and weight goals on a keto diet. Additionally, regular exercise and adequate rest are vital for optimal health.
