Ground Beef Lettuce Tacos with Cheese and Avocado

Why This Works for Intermittent Fasting

Ground beef is one of the most nutrient-dense proteins available — rich in zinc, iron, B vitamins, and complete amino acids that support muscle maintenance during extended fasting windows. The combination of beef fat and avocado provides slow-burning energy that keeps you satisfied for four to six hours without triggering another hunger cycle. Using crisp lettuce cups instead of tortillas keeps net carbohydrates near zero, making this equally well-suited to 16:8, 18:6, and OMAD protocols.

Ingredients

For the beef:

• 400 g ground beef (20% fat preferred)
• 1 tbsp ghee or butter
• 1 tsp ground cumin
• 1 tsp smoked paprika
• ½ tsp garlic powder
• ½ tsp onion powder
• ¼ tsp chilli flakes (optional)
• Salt and black pepper to taste

For assembly:

• 8 large iceberg or butter lettuce leaves, cup-shaped
• 1 ripe avocado, sliced or roughly mashed
• 60 g cheddar cheese, grated
• 2 tbsp full-fat sour cream
• Juice of ½ lime
• Fresh coriander (optional)

Instructions

1. Heat ghee or butter in a large skillet over medium-high heat until shimmering.
2. Add the ground beef and break it apart with a wooden spoon. Let it cook undisturbed for 2 minutes to develop some browning on the bottom, then stir and continue cooking.
3. Once the beef is mostly browned (about 6–8 minutes total), tilt the pan and spoon off excess fat if needed, leaving about 1 tablespoon in the pan.
4. Add the cumin, smoked paprika, garlic powder, onion powder, chilli flakes, salt, and black pepper. Stir well to coat the meat and cook for 1–2 minutes more to bloom the spices.
5. Remove from heat. Squeeze the lime juice over the meat and stir to combine.
6. Arrange the lettuce leaves on a board or two plates, shaped like open taco shells.
7. Spoon the beef evenly into each lettuce cup. Top with grated cheddar, avocado, and a small dollop of sour cream.
8. Garnish with fresh coriander if using. Serve immediately while the beef is still warm.

Fasting Compatibility

These tacos fit naturally into a 16:8 or 18:6 eating window as a satisfying main meal. The high fat and protein combination keeps hunger at bay for several hours without spiking insulin. For OMAD, serve alongside a simple green salad with olive oil and a few sliced cucumber rounds to round out the plate.
