Understanding Ketogenic Diet

The ketogenic diet shifts your body from burning glucose to burning fat for fuel. Success on keto requires choosing foods very low in carbohydrates while high in healthy fats and moderate in protein.

Ketosis occurs when carbohydrate intake drops below ~50g daily, forcing your liver to convert fatty acids into ketones for energy. This metabolic state has been shown to promote fat loss, reduce appetite, and improve insulin sensitivity.

Essential Nutrients for Ketogenic Diet

These nutrients play the most important role in achieving your Ketogenic Diet goals:

Diet Tips for Ketogenic Diet

1

Keep Carbs Under 20-50g Daily

Track net carbs (total carbs minus fiber) to stay in ketosis. Focus on non-starchy vegetables for your carb allowance.

2

Increase Healthy Fats

Fat should be 70-80% of calories. Include avocados, olive oil, nuts, seeds, and fatty fish. Don't fear dietary fat on keto.

3

Moderate Protein Intake

Aim for 1.2-1.7g protein per kg body weight. Too much protein can interfere with ketosis through gluconeogenesis.

4

Supplement Electrolytes

Keto causes water loss and electrolyte depletion. Supplement sodium, potassium, and magnesium to avoid "keto flu."

5

Focus on Whole Foods

Avoid "dirty keto" processed foods. Choose nutrient-dense whole foods for better health outcomes and satiety.

Lifestyle Tips for Ketogenic Diet

Nutrition is just one piece of the puzzle. Here are additional lifestyle factors that support Ketogenic Diet:

๐Ÿงช

Test Your Ketones

Use blood or breath ketone meters to confirm ketosis (0.5-3.0 mmol/L). Urine strips become less accurate over time.

๐Ÿ’ง

Stay Hydrated

Ketosis increases water loss. Drink at least 3-4 liters daily and add salt to food or water to maintain sodium levels.

๐Ÿ‹๏ธ

Adapt Training Volume

During the first 2-4 weeks of adaptation, reduce training intensity. Once fat-adapted, performance typically returns to normal.

๐Ÿ“Š

Track Macros Carefully

Use a food tracking app to monitor carbs, protein, and fat. Small miscalculations can kick you out of ketosis.

Common Mistakes to Avoid

โš ๏ธ

Not eating enough fat

Without adequate fat, you'll feel hungry and low-energy since you've cut both carbs and fat.

Better approach: Add butter, oil, nuts, and avocados liberally. Fat is your primary fuel source on keto.
โš ๏ธ

Eating too much protein

Excess protein can convert to glucose, potentially disrupting ketosis and fat burning.

Better approach: Keep protein moderate (20-25% of calories). Prioritize fat over protein portions.
โš ๏ธ

Not supplementing electrolytes

Keto depletes sodium, potassium, and magnesium, causing headaches, cramps, and fatigue ("keto flu").

Better approach: Add 3-5g sodium, 1-3g potassium, and 300-400mg magnesium daily through food or supplements.
โš ๏ธ

Giving up during the adaptation phase

The first 1-2 weeks are challenging as your body adapts to using fat for fuel. Many quit too early.

Better approach: Push through the adaptation period. Energy and mental clarity typically improve by week 3-4.

Frequently Asked Questions About Ketogenic Diet

How long does it take to enter ketosis?

Most people enter ketosis within 2-4 days of restricting carbs to under 20-50g daily. Full fat adaptation takes 3-4 weeks.

Can I do keto long-term?

Many people sustain keto long-term safely. However, some prefer cycling (periods of keto followed by higher-carb phases). Consult a healthcare provider.

Will I lose muscle on keto?

With adequate protein (1.2-1.7g/kg) and resistance training, muscle loss is minimal. Keto may even be muscle-sparing due to lower insulin.

What is "keto flu" and how do I avoid it?

Keto flu (fatigue, headaches, cramps) results from electrolyte depletion. Prevent it by supplementing sodium, potassium, and magnesium from day one.
