Are blueberries good for weight loss?

Blueberries have a well-deserved spot on the “nutritious and delicious” list. They’re naturally sweet, which can help curb dessert cravings, and they pack fiber, vitamins, and antioxidants into every bite. At just 57 calories per 3/4 cup, they’re low in calories but high in nutrients that help you feel fuller and support a healthy metabolism.

That said, no single food can lead to weight loss. Blueberries can be a great addition to your plan, but they work best when they’re part of an overall eating pattern that includes a variety of whole foods, balanced meals, and mindful portions.

✅ Quick answer

Blueberries are low in calories, full of fiber, and rich in antioxidants—making them a tasty, nutrient-dense choice that can support your weight-loss goals.

✅ Why blueberries can support your goals:

• Low calorie density means more volume – You can enjoy a satisfying portion without eating too many calories, helping you feel full while staying within your calorie goals.
• Fiber helps control hunger – With over 2 grams of fiber per 3/4 cup, blueberries help slow digestion and keep blood sugar stable, reducing in between-meal cravings.
• Antioxidants support metabolism – The anthocyanins that give blueberries their color may help improve how your body processes glucose and fat.

⚠️ Things to be mindful of:

• Natural sugars still count – While the 10 grams of natural sugar per 3/4 cup is better than added sugar, it still contributes to your daily carb intake.
• Easy to overeat – These little berries are so delicious and portable that it’s simple to mindlessly munch through multiple servings.
• Not a complete protein source – You’ll want to pair them with protein-rich foods to create more balanced, satisfying meals and snacks.
