Keto Diet Guide
Master the ketogenic diet with complete 7-day meal plan, 80+ keto-friendly foods, and expert tips for entering ketosis and maximizing fat loss.
What is the Keto Diet?
The ketogenic diet is a very low-carbohydrate, high-fat diet that shifts your body into a metabolic state called ketosis. In ketosis, your body becomes incredibly efficient at burning fat for energy instead of glucose from carbohydrates.
By drastically reducing carb intake to typically under 50 grams per day and increasing fat consumption to 70-75% of calories, your liver produces ketones from fat, which become your body's primary fuel source.
Core Principles
High Fat
70-75% of calories from healthy fats like butter, oils, avocados, and fatty meats.
Moderate Protein
20-25% of calories from protein. Too much can kick you out of ketosis.
Very Low Carb
Under 50g carbs daily, often 20-30g net carbs to maintain ketosis.
Stay Hydrated
Drink plenty of water and replenish electrolytes (sodium, potassium, magnesium).
Track Macros
Monitor carb, fat, and protein intake to stay in ketosis.
Test Ketones
Use strips or meters to verify you are in ketosis (0.5-3.0 mmol/L).

Frequently Asked Questions
What is the keto diet?
The ketogenic diet is a very low-carb, high-fat diet that puts your body into ketosis, a metabolic state where it burns fat for fuel instead of carbohydrates. Typically involves eating 70-75% fat, 20-25% protein, and 5-10% carbs (under 50g daily).
How long does it take to enter ketosis?
It typically takes 2-7 days to enter ketosis when restricting carbs to under 50g per day. Factors include your metabolism, activity level, and previous diet. You can test ketone levels with urine strips, breath meters, or blood meters.
What are the side effects of keto?
The keto flu is common in the first week, causing fatigue, headache, and irritability. Other side effects may include bad breath, constipation, and reduced athletic performance initially. Most symptoms resolve within 1-2 weeks as your body adapts.
Can I lose weight on keto?
Yes, keto is effective for weight loss. Studies show people lose more weight on keto compared to low-fat diets in the short term. Weight loss occurs through reduced appetite, water loss, and increased fat burning in ketosis.
What can I eat on keto?
Eat high-fat foods like meat, fish, eggs, butter, oils, avocados, cheese, nuts, and low-carb vegetables. Avoid grains, sugar, fruit (except berries), beans, and starchy vegetables.
Do I need to count calories on keto?
While keto naturally reduces appetite, calories still matter for weight loss. Track your intake initially to ensure you are in a calorie deficit. Many people find they eat less naturally on keto due to increased satiety.
