Understanding Keto Basics

What Puts You in Ketosis?

Ketosis happens when you restrict carbs enough that your body switches from burning glucose to burning fat for fuel. For most people, this means:

• Under 50g total carbs per day (loose keto)
• Under 20g net carbs per day (strict keto)

Net carbs = Total carbs minus fiber. Fiber doesn't spike blood sugar, so it doesn't count against your carb limit.

The Macros That Matter

A typical keto breakdown:

• 70-75% fat – The majority of your calories
• 20-25% protein – Moderate, not excessive
• 5-10% carbs – Your strict limit

What to Eat

Yes:

• Meat, fish, eggs
• Non-starchy vegetables (leafy greens, broccoli, cauliflower, zucchini)
• Cheese, butter, cream
• Nuts and seeds
• Avocados
• Olive oil, coconut oil

No (or very limited):

• Bread, pasta, rice
• Potatoes, corn
• Sugar in all forms
• Most fruits (berries in moderation are okay)
• Beans and legumes

Common Keto Mistakes

1. Not Eating Enough Fat

Keto is high-fat, not high-protein. If you're hungry all the time, you probably need more fat.

2. Hidden Carbs

Sauces, dressings, and "sugar-free" products can sneak in carbs. Always check labels.

3. Not Replacing Electrolytes

When you cut carbs, you lose water and electrolytes. Supplement sodium, potassium, and magnesium.

4. Expecting Instant Results

It takes 2-4 weeks to become fully fat-adapted. The first week might feel rough (keto flu). Push through.
