What Is the Ketogenic Diet? (The Simple Explanation)
The ketogenic diet is a very low-carbohydrate, high-fat eating pattern designed to shift your body into a metabolic state called ketosis. In ketosis, your liver converts fat into ketone bodies, which your brain and muscles use as fuel instead of glucose from carbohydrates.
The shift typically takes 2–4 days of strict carb restriction. Once you're in ketosis, most people report reduced hunger, more stable energy throughout the day, and accelerated fat loss compared to standard calorie restriction.
Keto Macros: How to Calculate Your Fat, Protein and Carb Targets
A standard ketogenic diet follows these macro ratios:
- Carbohydrates: 5–10% of total calories (typically under 25g net carbs per day)
- Protein: 20–25% of total calories
- Fat: 65–75% of total calories
For a 1,800-calorie keto diet (a typical target for a moderately active person wanting to lose weight), this breaks down to roughly:
- Carbs: 22–45g total (aim for under 25g net carbs)
- Protein: 90–112g
- Fat: 130–150g
Net carbs = total carbs minus fiber. Most non-starchy vegetables, full-fat dairy, and fatty meats are naturally low in net carbs and fit easily into a keto plan.
What to Eat on Keto: Full Food List
Proteins: eggs, beef, pork, chicken thighs (not breast — too lean), salmon, tuna, bacon, sausage (check for sugar), deli meats
Fats: butter, ghee, olive oil, coconut oil, avocado, avocado oil, heavy cream, cheese, full-fat sour cream
Non-starchy vegetables (eat freely): leafy greens, spinach, kale, zucchini, broccoli, cauliflower, bell peppers, mushrooms, asparagus, green beans
Dairy: hard cheeses (cheddar, gouda, parmesan), cream cheese, Greek yogurt (plain, small amounts), heavy whipping cream
Nuts and seeds: macadamia nuts, almonds, walnuts, pecans, chia seeds, flaxseeds (in moderation — easy to overeat)
What to Avoid on Keto
- All grains: bread, pasta, rice, oats, tortillas
- Sugar and sweeteners (except stevia/monk fruit/erythritol)
- Most fruit (exception: small amounts of berries)
- Legumes: beans, lentils, chickpeas
- Root vegetables: potatoes, sweet potatoes, carrots (in large amounts)
- Low-fat products (they replace fat with sugar)
- Beer and most alcohol (dry wine in moderation is fine)

Keto Flu: What It Is and How to Prevent It
During the first 3–5 days of keto, many beginners experience what's called the "keto flu" — headaches, fatigue, irritability, and brain fog. This is not actually a flu; it's the result of electrolyte loss as your kidneys excrete excess sodium when insulin levels drop.
Prevention is straightforward:
- Salt your food generously — add sea salt to meals, drink bouillon broth
- Magnesium: 300–400mg before bed (reduces leg cramps and headaches)
- Potassium: eat avocados and leafy greens, or supplement lightly
- Drink more water than usual — aim for 3+ liters per day
Most people who experience keto flu can eliminate symptoms within 24 hours by drinking a cup of salted bone broth.
