Thinking about trying a low-carb lifestyle? The keto diet plan is one of the most popular and effective ways to lose weight and feel more energetic. By dramatically reducing your carbohydrate intake and increasing your fat consumption, you encourage your body to enter a metabolic state called ketosis—where it burns fat for fuel instead of glucose.

What Is the Keto Diet?
The ketogenic (keto) diet is a high-fat, moderate-protein, low-carb diet. It shifts your metabolism away from carbs and toward fat and ketones for energy.
How the Keto Diet Works
When you cut out carbs, your body produces ketones in the liver, which serve as an alternative fuel source. This helps:
- Burn fat efficiently
- Stabilize blood sugar
- Reduce hunger and cravings
Benefits of a Ketogenic Lifestyle
- Rapid fat loss
- Improved mental clarity
- Reduced inflammation
- Balanced energy levels
- Better blood sugar control
Understanding the Science Behind Keto
What Happens During Ketosis?
Ketosis is a natural metabolic process. When carbs are scarce, your body breaks down fat into ketones in the liver. These ketones then become the main energy source for your brain and body.
Carbs, Fats, and Protein Balance
- Carbs: Limited to 20–50g/day
- Fats: 70–75% of daily calories
- Protein: 20–25% of daily calories
Effects on Metabolism and Energy
Ketosis shifts your energy source from glucose to fat, which leads to:
- Increased fat burning
- Decreased insulin levels
- Steady energy without crashes
Who Should Follow a Keto Diet?
Ideal Candidates
- People looking to lose weight
- Those managing type 2 diabetes or insulin resistance
- Individuals seeking mental focus and reduced sugar cravings
Medical Conditions That May Benefit
- Epilepsy (original purpose of keto)

Who Should Avoid Keto?
- People with gallbladder issues

Different Types of Keto Diets
1. Standard Ketogenic Diet (SKD)

2. Cyclical Keto Diet (CKD)
- Involves 5 keto days + 2 high-carb days (ideal for athletes)
3. Targeted Keto Diet (TKD)

4. High-Protein Keto
