150g of raw blueberries is about 86 calories. That estimate comes from the standard nutrition value for raw blueberries, which is roughly 57 calories per 100g.
If you are logging food for weight loss, macros, or meal planning, the easiest way to be accurate is to weigh the blueberries, check whether they are fresh, frozen, or sweetened, and then use the per-100g value to calculate the total.
1. Start with the standard calorie value
Raw blueberries are commonly listed at about 57 calories per 100 grams. To estimate 150 grams, multiply 57 by 1.5, which gives 85.5 calories. In everyday tracking, that rounds to about 86 calories.
This number is most useful when the blueberries are plain, raw, and unsweetened. If you are using packaged blueberries with added sugar or syrup, the calorie count can be higher, so the label matters more than the fruit estimate.
2. Weigh the portion instead of guessing by volume
Use a kitchen scale if you can. A scale removes the biggest source of error: eyeballing a handful or a cup. Blueberries are small and pack differently depending on how tightly they sit in a bowl, so volume can mislead you.
If you do not have a scale, remember that 150g of blueberries is close to 1 cup for many berries, but cup measurements are still less precise than grams. For calorie tracking, grams are the better choice.
3. Adjust for fresh, frozen, or sweetened blueberries
Fresh and plain frozen blueberries are usually very similar in calories per gram. The main difference shows up when the product contains added sugar, juice, or syrup. Those extras increase the calorie total even if the fruit amount stays the same.
For the most accurate count, read the package and log what is actually in the container. If you are weighing a bowl of thawed berries, drain off excess liquid first if the label suggests doing so.
4. Log the number in a way that fits your goal
For general nutrition tracking, logging 150g as about 86 calories is usually close enough. If you are tracking macros closely, use the grams from your scale and the nutrition label or database entry you trust most.
If your goal is better portion control overall, pairing accurate food tracking with consistent training can help. Fitnit can support workout logging with automatic rep counting for common bodyweight and strength exercises, plus manual input for other workouts, so your activity record stays as organized as your food log.
Tips
- Use grams, not cups, when you want the most accurate calorie count.
- Round 150g of plain blueberries to about 86 calories.
- Check the label for sweetened frozen blueberries, because added sugar changes the total.
- If you track macros, log the exact weight before eating, not after the berries have been mashed or mixed.
- Keep a few common fruit weights saved in your app so you do not recalculate them every time.
