For more energy and a sharper mind, here's what I eat at breakfast, lunch and dinner: Sleep doctor

Many of us know the basics of a good night's sleep: Stick to a bedtime routine, put away the screens, and try to get seven to nine hours of rest a night.

But we rarely talk about the things we do during the day that quietly sabotage our sleep. One of the most overlooked is what we eat. Food isn't just fuel. It sends signals to your brain, gut, and circadian system. The nutrients you absorb during the day influence your mood, energy levels, and how well you sleep at night.

As a sleep doctor, I pay close attention to what goes on my plate. Some foods help me stay focused. Others help me wind down. And a few are small, delicious tools that help me fall — and stay — asleep. Here's what I eat every day to boost my energy, sharpen my mind, and easily relax by nighttime. 

For breakfast, I usually have eggs for protein, followed by a small bowl of fruit topped with pumpkin seeds.

Here are other foods you can include to start the day with more energy, focus, and gut support:

• Avocados are rich in healthy fats and magnesium, which helps keep your blood sugar steady and reduces the risk of late-day energy crashes.
• Oats have plenty of complex carbohydrates and tryptophan, which helps make and support serotonin and energy regulation.
• Almonds or pumpkin seeds are great sources of magnesium, which helps regulate stress and supports melatonin production later in the day.
• Yogurt and kefir are fermented foods that support gut health, which is closely linked to mood and sleep via the gut-brain connection.

At lunch, I have meals that support focus and reduce inflammation. Fatty fish, legumes, and fresh vegetables are all part of my routine.

Here are some great lunch options that nourish your brain and support better sleep later on: 

• Fatty fish, especially salmon or sardines, are packed with omega-3s and vitamin D, both of which support mental clarity and better sleep.
• Chickpeas are rich in fiber, B vitamins, and magnesium, all of which contribute to better sleep quality and metabolic health.
• Tomatoes are a top source of lycopene, an antioxidant associated with improved sleep duration and cardiovascular protection.

In the afternoon, I keep things light. If I need something to hold me over until dinner, I might reach for fruit or a handful of seeds or nuts.

These snack options can help stabilize energy and support your body's transition into evening:

• Watermelon is hydrating and rich in lycopene and other antioxidants.
• Grapefruit is a great source of carotenoids, and fiber, which helps supports digestion.
• Pistachios are naturally rich in melatonin and packed with healthy fats and plant protein — a great option to help your body start winding down.
• Dark chocolate, in small amounts, contains serotonin-boosting compounds, antioxidants, and magnesium. I recommend eating it at least three to four hours before bed due to caffeine content.

Dinner is when I focus most on sleep-promoting foods. I usually have protein with legumes.

I also love starting the meal with something tomato-based. In the winter, that's often a warm tomato soup. In the summer, I'll make a chilled gazpacho. After dinner, I always eat a kiwi or, if I can find them, some tart cherries.

Here are some foods that help your body wind down:

• Dark leafy greens, such as spinach or Swiss chard, are rich in magnesium, iron, and folate. These nutrients help regulate the circadian rhythm.
• Whole grains (like quinoa or brown rice) are good sources of complex carbohydrates that support steady energy and help the brain absorb tryptophan more effectively.
• Turkey is high in protein and tryptophan. It's a good alternative animal protein that promotes satiety and can support sleep when eaten in moderation at dinner.
• Tart cherries are one of the few natural sources of melatonin, which improves sleep quality and duration. 
• Kiwis are high in antioxidants and serotonin. Studies show it may help people fall asleep faster and stay asleep longer.
• Milk is a traditional evening choice for a reason. Whether it's whole or reduced fat, it's rich in tryptophan, it supports melatonin production, and it is also high in alpha-lactalbumin, which aids digestion and strengthens your immune system. 

Of course, you should always consult with your physician before making any drastic changes to your diet. You want to make sure that you are doing what is best for you and your health.

When you treat meals as part of your sleep hygiene, you're not just eating to get through the day. You're giving your body what it needs to rest, repair, and show up with more clarity and energy the next day.
