What is the Keto Diet?

The keto diet (short for ketogenic diet) is a low-carb, high-fat diet designed to put your body into ketosis. This diet plan focuses on restricting carbohydrate intake so that the body enters a state of ketosis. Ketosis is a natural phenomenon, a normal metabolic process that puts our body in survival mode due to low carbohydrate intake. When our body does not have enough sugar (glucose) for energy, it starts burning stored fat, which causes our body to build up acids called ketones.

How does the ketogenic diet work?

The keto diet’s main goal is to force the body to use a different fuel type. Instead of relying on glucose from carbohydrates like vegetables, grains & pulses, and fruits, the ketogenic diet relies on ketone bodies, a type of fuel produced by the liver from stored fat. Here’s a simple breakdown of how it works:

🔁 Normal Body Function (with Carbs):

Glucose is your main source of energy.
You eat carbohydrates (like bread, rice, sugar):
Your body breaks them down into glucose (sugar).
Insulin helps move glucose into your cells.

🧠 What Happens on Keto:

You cut back on your carbs a lot (usually 20-50 grams per day).
Your body runs out of glucose.
It looks for a new fuel source: fat.

🔥 Ketosis begins:

Your liver breaks down fat and turns it into ketones.
Ketones become your body’s new fuel, especially for the brain.
You start burning fat for energy — from food and stored body fat.

💥 Main effects:

Weight loss (due to fat burning and decreased appetite).
Stable energy levels (no sugar crashes).
Improved blood sugar control (very low carb intake).

Here are the main disadvantages and risks of following a keto diet plan, especially if it is not done correctly:

What are some myths associated with Keto Diet?

The ketogenic (keto) diet has gained popularity, which has led to some misconceptions. Let’s address some common misconceptions:

Misconception 1: The keto diet allows for unlimited fat intake

While the keto diet is high in fat, it’s essential to focus on healthy fats. Excessive amounts of unhealthy fats, such as processed meats, which are high in saturated fat, can negatively impact heart health. It’s recommended to focus on unsaturated fats from sources like avocado, olive oil, and nuts.

Misconception 2: The keto diet is essentially a fad diet

While the keto diet has become trendy, it was originally developed to treat epilepsy in children. Its therapeutic origins suggest that it’s more than just a fad.

Misconceptions 3: Carbohydrates are inherently bad

Carbohydrates are an important source of energy for the body. The keto diet restricts carbohydrates to induce ketosis, but that doesn’t mean all carbohydrates are bad. Complex carbohydrates found in whole grains, fruits, and vegetables provide essential nutrients and fiber.

Myth 4: The keto diet causes muscle loss

When followed properly with adequate protein intake, the keto diet can preserve muscle mass. Incorporating strength training and ensuring adequate protein intake is crucial to maintaining muscle.

Myth 5: The keto diet is not sustainable

Adherence patterns vary among people. Some find the keto diet sustainable, while others may struggle. Success depends on personal preference, lifestyle, and proper planning.

Myth 6: The keto diet is harmful to kidney health

A well-planned keto diet is moderate in protein and generally does not harm kidney function in healthy individuals. However, those with kidney problems should consult a healthcare provider before starting.

Understanding these misconceptions can help individuals make informed decisions about the keto diet. A healthcare professional should be consulted before making significant dietary changes.
