Tuna Stuffed Avocado Halves

Why This Works for Intermittent Fasting

Tuna stuffed avocado is one of the most efficient meals you can eat during your eating window. The avocado provides a generous dose of healthy monounsaturated fat and potassium — two nutrients that drop during fasting — while the tuna delivers high-quality protein with near-zero carbohydrate impact. Together they create a meal that is deeply satisfying without causing an insulin spike, meaning you get full without disrupting the metabolic benefits of your fast.

Ingredients

• 2 ripe avocados, halved and pitted
• 2 cans (around 140g each) tuna in olive oil or spring water, drained
• 2 tablespoons full-fat mayonnaise (made with olive oil, not seed oils)
• 1 tablespoon capers, roughly chopped
• 1 tablespoon lemon juice (fresh)
• 1 small celery stalk, finely diced
• 2 teaspoons Dijon mustard
• Salt and freshly ground black pepper to taste
• Fresh dill or flat-leaf parsley, to serve
• Optional: pinch of chilli flakes

Instructions

1. Halve the avocados and remove the pits. If the hollow left by the pit is small, scoop out a little extra flesh and mix it into the tuna filling to create more room.
2. In a bowl, combine the drained tuna, mayonnaise, capers, lemon juice, diced celery, and Dijon mustard. Mix well until combined.
3. Season the tuna mixture generously with salt and freshly ground black pepper. Add chilli flakes if using.
4. Spoon the tuna filling into the hollow of each avocado half, mounding it slightly above the rim.
5. Garnish with fresh dill or parsley and a squeeze of extra lemon if desired.
6. Serve immediately.

Fasting Compatibility

Best for: 16:8, 18:6, OMAD, and any time-restricted eating protocol. This meal is ideal as either the first meal breaking a fast or the sole meal in a shorter eating window. The combination of fat and protein means satiety lasts 4–6 hours, making it well suited for people managing a tight eating window. It is also suitable for ketogenic and carnivore-adjacent protocols.

Notes

• Use tuna in olive oil for a richer texture and added healthy fat
• If making ahead, keep the tuna filling refrigerated and fill the avocado just before eating to prevent browning
• For extra richness, add a tablespoon of full-fat cream cheese to the filling
