Choosing the Right Fasting Schedule

1. 16:8 Method: Fast for 16 hours and eat within an 8-hour window.

• Best for CrossFit Athletes: Allows flexibility to train and recover during your eating window.

• Example: Eating window from 12 PM to 8 PM (workout in the late morning or early afternoon).

2. 14:10 Method: Fast for 14 hours and eat within a 10-hour window.

• Good for Beginners: Easier to sustain and fits well with CrossFit schedules.

3. 5:2 Method: Eat normally for 5 days a week and restrict calories to 500–600 on 2 non-consecutive days.

• Considerations: Might work better for rest days rather than intense workout days.


Tips for CrossFit Athletes Doing IF

1. Train During the Eating Window:

• Try to schedule workouts during or near the start of your eating window for better energy and recovery.

• For early morning workouts, consider a small pre-workout snack like BCAAs or a protein shake (if it doesn’t break your fast for your goals).

2. Break Your Fast with a Balanced Post-Workout Meal:

• Include lean protein, healthy fats, and complex carbs to replenish glycogen and aid muscle repair.

• Example: Grilled chicken, quinoa, and avocado, or a protein shake with fruit and almond butter.

3. Listen to Your Body:

• Adjust fasting times if you notice reduced performance or prolonged fatigue.

• Ensure you’re eating enough calories and nutrients to fuel intense CrossFit workouts.

4. Hydrate Strategically:

• Stay hydrated throughout your fast with water, electrolyte supplements, or black coffee.

• Proper hydration is crucial for endurance and recovery during WODs.

5. Use Rest Days for Longer Fasting Periods:

• On less intense training days or rest days, you can extend your fasting window (e.g., a 20:4 schedule) to maximize the metabolic benefits of fasting.



Sample Daily Schedule (16:8 for CrossFit)



• 7:00 AM: Early morning workout (optional pre-workout: black coffee or BCAAs).

• 12:00 PM: Break your fast with a balanced meal (grilled salmon, sweet potato, greens).

• 4:00 PM: Light snack (Greek yogurt, nuts, or a protein bar).

• 7:30 PM: Final meal (chicken stir-fry with brown rice and vegetables).

• 8:00 PM - 12:00 PM: Fasting begins.



Additional Tips
1. Supplements: Consider adding magnesium, omega-3s, or multivitamins to fill any potential nutrient gaps.

2. Progress Tracking: Monitor performance in WODs, energy levels, and body composition to ensure the fasting routine works for you.

3. Adjust for Goals:

• If weight loss is the goal, ensure a calorie deficit during the eating window.

• For strength and performance, prioritize calorie and protein intake during meals.



EXAMPLE: 16:8 Intermittent Fasting Meal Plan
Fasting Window: 8:00 PM – 12:00 PM
Eating Window: 12:00 PM – 8:00 PM

Goal: Replenish glycogen stores, repair muscles, and refuel for the day.

• Grilled Chicken Power Bowl:

• 4 oz grilled chicken breast.

• 1/2 cup cooked quinoa.

• 1 cup steamed broccoli or spinach.

• 1/4 avocado (healthy fats).

• Olive oil and lemon juice for dressing.

• Optional Add-On: 1 piece of fruit (apple or banana).



Snack (Pre-Workout or Midday Snack: 3:30 PM)



Goal: Provide light fuel before your workout.

• Greek Yogurt & Berries:

• 1 cup plain Greek yogurt (high in protein).

• 1/2 cup cooked brown rice or cauliflower rice.

• Low-sodium soy sauce or coconut aminos.

Optional Dessert:

• Dark chocolate square (70% cacao or higher).



Key Tips

1. Calorie Intake: Adjust portion sizes based on your goals (weight loss, maintenance, or performance).

2. Protein Focus: Aim for 1.6–2.2g protein per kg of body weight daily to support muscle repair.

3. Healthy Fats: Include fats from sources like avocado, olive oil, nuts, or seeds for sustained energy.

4. Hydration: Drink 3–4 liters of water daily, especially during fasting hours. Add electrolytes if needed.

5. Meal Prep: Cook meals in bulk to save time and ensure you stick to the plan.


Here are 5 tips to be successful at intermittent fasting (IF):

1. Start Gradually

• Ease into intermittent fasting by gradually increasing your fasting window.

• For example, begin with a 12:12 schedule (12 hours fasting, 12 hours eating) and work toward 16:8 or 18:6.


2. Stay Hydrated
• Drink plenty of water throughout the fasting period to stay hydrated and curb hunger.
• Include black coffee, tea, or herbal teas, as these are typically fasting-friendly and can suppress appetite.

3. Prioritize Nutrient-Dense Meals
• When breaking your fast, focus on whole, nutrient-dense foods.
• Include a balance of lean protein, healthy fats, and complex carbs to keep you full and energized.
• Avoid overeating or indulging in high-sugar or processed foods.

4. Plan Around Your Lifestyle
• Choose a fasting schedule that aligns with your daily routine and workouts.
• For example, if you work out in the morning, try eating your first meal post-workout.
• Ensure your eating window supports social and family commitments to stay consistent.

5. Manage Hunger and Cravings
• Combat hunger by:
• Drinking water or sipping on calorie-free beverages.
• Distracting yourself with activities during fasting hours.
• Eating high-fiber and protein-rich meals during your eating window.
• Hunger usually diminishes after a few days of consistency.
