What Is the Keto Diet? A Quick Overview
The ketogenic diet (keto) is a low-carb, high-fat, moderate-protein diet designed to shift your body from using glucose as its main fuel to burning fat and producing ketones for energy. This metabolic state is called ketosis.
Typical keto macro ranges are:
| Macro | Percentage |
|---|---|
| Fat | 70–80% |
| Protein | 15–25% |
| Carbs | 5–10% (usually under 20–50 grams of net carbs per day) |

The 9 Rules of Keto Diet (Complete Breakdown)
Here are the exact 9 rules of keto diet you must follow to enter and stay in ketosis.
Rule 1: Keep Carbs Under 20–50 Grams Per Day
This is the core of keto.
-
Your body stores very little glucose (carbs).
-
Once you stop feeding it carbs, it is forced to burn stored fat instead.
The stricter end for most people is:
👉 20 g net carbs/day
This means:
-
No sugar
-
No bread
-
No pasta
-
No rice
-
No starchy fruits or vegetables
Better options: leafy greens, broccoli, cauliflower, mushrooms, cucumber.

Rule 2: Increase Fat Intake to 70–80% of Daily Calories
Fat becomes your primary fuel.
Healthy keto fats include:
-
Avocado
-
Olive oil
-
Coconut oil
-
Butter
-
Ghee
-
Nuts & seeds
-
Fatty meats
-
Egg yolks
Avoid unhealthy fats: margarine, processed seed oils (soybean, canola, corn).
Rule 3: Consume Moderate Protein — Not Too High, Not Too Low
High protein can kick you out of ketosis because excess protein converts to glucose through gluconeogenesis.
Aim for:
👉 0.8–1.2 g protein per kg of body weight
Examples:
-
Eggs
-
Chicken
-
Beef
-
Salmon
-
Tuna
-
Greek yogurt (unsweetened)
Rule 4: Remove All Sugars and High-Carb Foods
This includes the obvious ones and the sneaky ones:
❌ Not Allowed
-
Sugar
-
Honey
-
Maple syrup
-
Soda
-
Chips
-
Fruit juices
-
Bananas, apples, grapes
-
Bread, rice, pasta
-
Beans, lentils
✔ Allowed
-
Berries (moderate)
-
Stevia or monk fruit as sweeteners
Rule 5: Eat Whole Foods — Avoid Processed Keto Products
Many “keto-friendly” snacks are filled with:
-
Artificial sweeteners
-
Inflammatory oils
-
Low-quality proteins
These can stall weight loss and spike insulin.
Stick to single-ingredient whole foods as much as possible.
Rule 6: Stay Hydrated and Maintain Electrolytes
When carbs drop, your body excretes water and electrolytes.
This can cause keto flu, especially in the first 7 days.
Key electrolytes:
| Electrolyte | Daily Goal | Source |
|---|---|---|
| Sodium | 3–5 g | Salt, broth |
| Potassium | ~3,000–4,000 mg | Avocado, spinach |
| Magnesium | 300–400 mg | Nuts, supplements |
Drink minimum:
👉 2.5–3 liters of water/day
Rule 7: Track Macros (At Least in the Beginning)
To get into ketosis consistently:
-
Use apps like Cronometer, Carb Manager, or MyFitnessPal (manual adjustments required).
-
Measure your carbs properly.
-
Make sure hidden ingredients don’t push you over carb limits.
Tracking for 1–2 weeks helps your body adapt faster.
Rule 8: Allow the Body Time to Adapt (Keto Adaptation Takes 2–6 Weeks)
The first phase includes:
-
Tiredness
-
Headaches
-
Sugar cravings
-
Brain fog
-
Irritability
These symptoms fade once your body becomes fat-adapted.
After adaptation:
-
Increased energy
-
Appetite suppression
-
Better focus
-
Stable blood sugar
Rule 9: Test Ketone Levels to Stay on Track
You can measure ketones in 3 ways:
1. Breath Ketone Meters
Reusable, convenient.
2. Blood Ketone Meters
Most accurate.
Ideal ketosis range:
👉 1.5 – 3.0 mmol/L
3. Urine Strips
Good for beginners (less accurate later).
