Eating for Energy: High-Protein Snacks that Fight Third-Trimester Fatigue
Key Takeaways
Third-trimester fatigue is often caused by increased blood volume and the baby's rapid growth. Consuming high-protein snacks like Greek yogurt and eggs helps stabilize blood sugar and maintain energy levels. Aim for at least 75 grams of protein daily and snack every two to four hours for optimal support.
Feeling drained during the third trimester? It is completely normal—your body is working harder than ever to support your baby’s rapid growth. The good news? High-protein snacks can help you stay energized, stabilize blood sugar, and curb hunger while aiding your baby’s development. Here is what you need to know:
- Protein is key: Aim for 10g per snack to maintain steady energy and meet your increased nutritional needs.
- Why fatigue happens: Increased blood volume, extra weight, and your baby’s growth demand more energy and nutrients.
- Snack ideas: Greek yogurt, hard-boiled eggs, nut butter sandwiches, hummus with veggies, and cottage cheese are easy, protein-packed options.
- Timing matters: Snack every 2–4 hours to prevent energy dips and keep blood sugar stable.
Preparation is your best friend—batch-cook snacks like hard-boiled eggs or yogurt parfaits and store them for easy access. Eating smart now not only keeps you energized but also supports your recovery and milk supply after birth.
What Causes Third-Trimester Fatigue
Fatigue is incredibly common in the final weeks of pregnancy, with around 90% of women experiencing it. This exhaustion can be traced back to several physical changes your body is undergoing.1
For starters, your heart is working overtime. The increased blood volume needed to support your baby puts extra strain on it, which can leave you feeling drained. On top of that, carrying an additional 20 to 30 pounds puts stress on your joints and muscles, making even simple movements feel more taxing.
Your baby's rapid growth during this stage is another major factor. As they develop organs and tissues, your body redirects a significant amount of energy to support this process. According to UF Health:2
A lot of your body's energy is directed toward supporting a rapidly growing fetus. It's common to feel the need to reduce your activities and your work load.
This growth also increases your nutritional needs. Your body requires a steady supply of amino acids from protein and more iron to produce the red blood cells that carry oxygen to both you and your baby. To meet these demands, you'll need about 450 extra calories every day. If you're not getting enough protein or essential nutrients, your blood sugar levels can fluctuate, leading to energy crashes.
Incorporating protein-packed snacks into your daily routine can help stabilize blood sugar levels and give your body the consistent energy it needs to power through these changes.
High-Protein Snacks to Fight Fatigue
During the third trimester, the right snacks can be a game-changer. Your body needs around 75g of protein daily to support your baby's growing organs and the changes in your own body.3 If you're feeling drained, these five easy, protein-packed snacks can help keep your energy up without adding to your exhaustion.
Greek Yogurt Parfait with Berries and Granola
Greek yogurt is a powerhouse. A 5.3-ounce container of plain Greek yogurt provides 14g of protein, which is twice the amount found in regular yogurt. Layer it with fresh berries like blueberries or strawberries for a boost of fiber and antioxidants. Sprinkle on granola or walnuts for added crunch. Plus, the probiotics in Greek yogurt can help ease pregnancy-related digestive issues.
Stick to plain varieties to avoid added sugars, which can cause blood sugar spikes and energy crashes.
Cottage Cheese on Whole-Grain Toast
Cottage cheese is another high-protein option. A 4-ounce serving of 1% fat cottage cheese delivers 14g of protein with just 81 calories. Spread it on a slice of whole-grain toast for an extra 3.5g of protein and some fiber to support digestion.
For a sweet twist, top it with peach slices and a dash of cinnamon. Prefer savory? Add cherry tomatoes and fresh chives. As registered dietitian Natalie Carroll, RDN, notes:4
Snacks are often better tolerated later in pregnancy, when we often cannot eat a whole meal without feeling too full.
Nut Butter and Banana Sandwich
Peanut butter is not only delicious but also effective for keeping your energy steady. Two tablespoons pack 7.5g of protein along with healthy fats that help slow digestion. Spread it on whole-grain bread, then layer banana slices on top for potassium, which helps maintain fluid balance and may reduce swelling during the third trimester.
Hard-Boiled Eggs with Fruit and Vegetables
Hard-boiled eggs are a simple, grab-and-go snack that is rich in complete protein. One large egg contains 6g of protein and 125mg of choline, which is essential for your baby’s brain development. Pair them with apple slices, baby carrots, or bell pepper strips for added fiber and vitamin C.
Hummus and Vegetable Sticks
Hummus is a great plant-based protein source, with a quarter cup offering 3g of protein along with folate and fiber. Pair it with hydrating veggies like cucumber slices, celery sticks, or bell pepper strips.
| Snack Component | Protein Content | Key Third-Trimester Benefit |
|---|---|---|
| Greek Yogurt (5.3 oz) | 14g | Probiotics for digestion; calcium for bones |
| Cottage Cheese (4 oz) | 14g | High protein-to-calorie ratio; versatile |
| Hard-Boiled Egg (1 large) | 6g | Choline for fetal brain development |
| Peanut Butter (2 tbsp) | 7.5g | Healthy fats for lasting energy |
| Hummus (1/4 cup) | 3g | Plant-based protein and folate |
How to Prepare and Store Snacks
Once you have chosen your high-protein snacks, the next step is making sure they are easy to grab when you need them most. A little preparation and smart storage can save you a ton of time. Dedicate an hour on a Sunday to whip up enough snacks for the week.
Hard-boiled eggs can stay fresh in the fridge for up to a week if kept in their shells. Yogurt parfaits and herb-infused dips last about four days refrigerated. If you are reheating egg or meat-based snacks, make sure they reach an internal temperature of 165°F to keep them safe to eat during pregnancy.
Portioning snacks ahead of time can make all the difference. Divide cottage cheese, Greek yogurt, or hummus into single-serving containers. If you are heading to the hospital, check your hospital bag and pack a small cooler with ice packs to keep everything fresh.
When to Eat Snacks for Steady Energy
To keep your energy steady and your blood sugar stable, try eating a high-protein snack every two to four hours. During the third trimester, adding two to three protein-packed snacks between meals can help meet your nutritional needs and combat fatigue.
Evening snacks are just as important. Before bed, go for slow-digesting proteins like cottage cheese or Greek yogurt to stabilize blood sugar levels overnight and reduce morning fatigue. Cottage cheese is a standout option because it is rich in casein, a protein that releases amino acids slowly while you sleep.
Conclusion
Tackling third-trimester fatigue can be as simple as reaching for high-protein snacks that keep your body fueled and support your baby's development. Protein plays a crucial role in expanding blood volume, aiding uterine growth, and preparing your body for both labor and postpartum recovery.5
In these final weeks, smart snacking becomes more than just a habit—it is an essential part of your prenatal care. Make every choice count by focusing on protein-rich options to keep your energy steady and support your recovery as you prepare to welcome your baby.
