Keto Diet: What It Is, How It Works, and Meal Plans

The keto diet, or ketogenic diet, is a high-fat, low-carbohydrate eating plan that has been used for decades to treat medical conditions and, more recently, for weight loss. This article explains what a keto diet is, how it works, its benefits, and provides a sample keto diet plan to help you get started.

What is the Keto Diet?

The ketogenic diet is a high-fat, low-carb, moderate-protein diet designed to induce ketosis, a metabolic state where the body burns fat for energy instead of carbohydrates. Typically, it consists of 70-80% fat, 20-25% protein, and 5-10% carbs. Types include the standard ketogenic diet (SKD), cyclical (CKD), targeted (TKD), and high-protein versions, with SKD being the most researched.

Why the Keto Diet Matters

Research suggests the keto diet can lead to significant weight loss, improve blood sugar control, and offer therapeutic benefits for conditions like epilepsy, diabetes, and neurological disorders. For example, a 2023 study found that 50% of children with epilepsy experienced at least a 50% reduction in seizures on the diet.

Key Components of the Keto Diet

Foods to Eat:

• Meat: Beef, pork, lamb
• Fatty fish: Salmon, mackerel
• Eggs
• Butter, cream, cheese
• Nuts and seeds: Almonds, walnuts
• Healthy oils: Olive, coconut
• Avocados
• Low-carb vegetables: Spinach, broccoli

Foods to Avoid:

• Sugary foods: Soda, candy
• Grains: Wheat, rice
• Most fruits, except berries
• Beans, legumes
• Starchy vegetables: Potatoes
• Low-fat products
• Alcohol

How Does the Keto Diet Work?

Normally, the body uses glucose from carbohydrates for energy. On a keto diet, low carb intake forces the liver to convert fat into ketones, which become the primary energy source, especially for the brain. This state, called ketosis, typically begins within 2-4 days of restricting carbs to under 50 grams daily.

For Whom Is the Keto Diet Appropriate?

The keto diet is often prescribed for children with refractory epilepsy, particularly those with conditions like Lennox-Gastaut or Dravet syndrome, where studies show up to 50% seizure reduction. It may also benefit adults seeking weight loss or improved metabolic health, though consultation with a healthcare provider is essential.

Keto Diet Plan

Below is a sample 7-day keto diet plan:

How to Start the Keto Diet

1. Consult a healthcare provider, especially for medical conditions.
2. Calculate macros: 70-80% fat, 20-25% protein, 5-10% carbs.
3. Plan meals with high-fat, low-carb foods.
4. Limit carbs to under 50 grams daily.
5. Stay hydrated and consider electrolytes.

Monitoring the Keto Diet

Monitor ketosis using:

• Urine strips: Affordable but less accurate over time.
• Blood meters: Precise but expensive.
• Breath analyzers: Measure acetone levels.

Side Effects and How to Manage Them

Common side effects include:

• Keto flu: Fatigue, headaches; manage with electrolytes.
• Constipation: Increase low-carb vegetable fiber.
• Bad breath: Temporary; maintain oral hygiene.

Supplements for the Keto Diet

Recommended supplements:

• Magnesium, potassium, sodium
• Omega-3 fatty acids
• Vitamin D

Takeaways

• The keto diet induces ketosis for fat burning.
• Effective for epilepsy and weight loss, with careful monitoring.
• Requires planning and medical consultation.
