This meal plan is written for general educational purposes and reviewed by a Registered Dietitian. Always consult your physician before making significant dietary changes, especially if you have pre-existing health conditions like diabetes or renal disease.
If traditional calorie-counting diets have left you feeling drained, constantly hungry, and frustrated by plateaus, the ketogenic diet offers a fundamentally different approach to fat loss and energy optimization.
By switching your body's primary fuel source from glucose (carbohydrates) to ketones (fat), keto helps stabilize blood sugar, reduce appetite-triggering ghrelin levels, and promote sustained mental clarity throughout the day.
What is Ketosis and How Does the Keto Diet Work?
Under standard dietary conditions, your body relies on carbohydrates for quick energy. When you consume carbs, they are broken down into glucose. Any excess glucose is stored in your liver and muscles as glycogen or stored as body fat.
When you restrict carbohydrate intake to under 20–50 grams of net carbs per day, your body depletes its glycogen reserves in 24 to 48 hours. Lacking glucose, your liver begins converting fatty acids into ketone bodies (acetoacetate, beta-hydroxybutyrate, and acetone), which your brain and muscles readily use for fuel. This metabolic state is known as ketosis.
- Fats: 70% to 75% of total daily calories
- Proteins: 20% to 25% of total daily calories
- Carbohydrates: 5% to 10% (typically under 20–30g net carbs)

How to Beat the "Keto Flu" & Maintain Electrolyte Balance
During the first 3 to 7 days of keto, your body excretes significant amounts of sodium and water as glycogen stores drain. This temporary drop in electrolytes can cause symptoms commonly referred to as the keto flu (headaches, fatigue, muscle cramps, and brain fog).
- Hydrate: Drink at least 3–4 liters of water daily.
- Increase Sodium: Add an extra 1/2 tsp of Himalayan pink salt to your meals or drink bone broth twice daily.
- Magnesium Supplementation: Take 300–400mg of Magnesium Glycinate before bed to support muscle relaxation and sleep quality.
- Potassium Intake: Eat avocados, dark leafy greens, and use potassium-rich salt substitutes.
Frequently Asked Questions
How long does it take to enter ketosis?
Most individuals enter initial ketosis within 24 to 72 hours of keeping net carb intake under 20–25 grams per day alongside moderate protein consumption.
Will keto cause muscle loss?
No, as long as you maintain adequate protein intake (1.6 to 2.0 grams per kg of body weight) and continue resistance training, keto is highly muscle-sparing.
Can I drink alcohol on keto?
Pure spirits like vodka, whiskey, tequila, and gin contain zero carbs. Avoid beer, sweet wines, and sugary mixers. Consume alcohol in moderation, as your liver prioritizes alcohol metabolism over ketone production.
