Trying keto but not seeing the results you expected? Or maybe intermittent fasting helped initially but your progress stalled? Here’s the game-changer: combining keto with intermittent fasting can supercharge fat burning, increase energy levels, and deliver faster, sustainable weight loss.

This powerful combination taps into your body’s natural fat-burning mechanisms and metabolic efficiency. In this blog, we’ll break down the science behind keto + IF, how to do it safely, and what your day should look like when using both.

What Is a Low Carb Diet?

The ketogenic (keto) diet is a high-fat, very low-carb eating style that forces your body into ketosis, a metabolic state where you burn fat for fuel instead of carbs.
Typical Macros : 70% fat / 25% protein / 5% carbs
Carb Limit : Under 20–50g of net carbs per day

Foods you eat on keto:

• Eggs, fatty fish, meat
• Avocados, olive oil, nuts
• Leafy greens, cauliflower, zucchini

What Is Intermittent Fasting (IF)?

Intermittent fasting is not about what you eat, but when. It involves eating during a specific window and fasting during the rest of the day.

Popular IF methods:

• 16:8: 16-hour fast, 8-hour eating window (most common)
• 18:6 or OMAD: More advanced forms with shorter windows

During the fasting window, your body:

• Uses stored fat for energy
• Lowers insulin levels
• Increases human growth hormone (HGH)

How to Combine Keto and Intermittent Fasting (Step-by-Step)

Step 1: Adapt to Keto First (Week 1–2)

Start your keto journey by limiting carbs (<20–30g/day)
Allow 1–2 weeks to enter ketosis and reduce “keto flu” effects

Step 2: Add Intermittent Fasting Gradually

Begin with 12:12 or 14:10 fasting schedule
Gradually move to 16:8 as you feel more stable

Step 3: Schedule Meals During Your Eating Window

Example (16:8 window: 12 PM to 8 PM):
12:00 PM (Break Fast): Eggs + avocado + greens
4:00 PM (Snack): Almonds + keto smoothie
7:30 PM (Dinner): Grilled salmon + broccoli + olive oil

Step 4: Stay Hydrated During Fast Drink:

• Water
• Black coffee (no cream/sugar)
• Herbal teas

These don’t break your fast and support fat metabolism.

Sample Daily Keto + IF Schedule (16:8)

Time Activity
8:00 AM Black coffee + water (start fast)
12:00 PM First meal: Keto omelet + avocado
4:00 PM Keto snack: nuts + cheese + cucumber
7:30 PM Dinner: Chicken thighs + salad + olive oil
8:00 PM Start fast again (no food until next day)

Common Mistakes to Avoid

• Fasting too soon on Day 1 of keto (you may feel weak or dizzy)
• Not eating enough fat to stay full during fasting hours
• Overeating during the eating window
• Breaking fast with carbs (spikes insulin)
• Not drinking enough water or electrolytes
