How Many Calories in a Slice of Bread?
Quick Answer
A standard slice of bread contains approximately 70 to 100 calories, depending on the type, thickness, and ingredients used.
Calories in Bread (By Type)
The calorie content varies significantly depending on the bread:
-
White bread (1 slice): ~80 calories
-
Wholemeal bread (1 slice): ~90 calories
-
Brown bread (1 slice): ~85 calories
-
Seeded bread (1 slice): ~100–120 calories
Thicker slices or bakery-style bread can contain even more calories per slice.
Calories in Bread per 100g
Bread contains approximately 240–265 calories per 100g, depending on the variety.
This makes it more calorie-dense than foods like rice or potatoes, but still manageable within a balanced diet.
Nutritional Breakdown of Bread
For a typical slice of white bread:
-
Protein: 2–4g
-
Carbohydrates: 12–15g
-
Fat: 1–2g
Bread is primarily a carbohydrate source, often used for quick and convenient meals.
Why Bread Calories Add Up Quickly
Bread is easy to underestimate because:
-
Most people eat multiple slices at once
-
It is often combined with butter, spreads, or fillings
-
Portion sizes vary widely
For example:
-
2 slices of white bread = ~160 calories
-
Add butter → can exceed 250+ calories
Is Bread Good for Weight Loss?
Bread can still be included in a calorie-controlled diet.
What matters most:
-
Total daily calories
-
Portion size
-
What you pair it with
Wholemeal or higher-fibre breads may help you feel fuller for longer compared to white bread.
Bread vs Other Carbohydrate Foods
Here’s how bread compares per typical serving:
-
Bread (1 slice): ~80–100 calories
-
Rice (100g cooked): ~130 calories
-
Pasta (100g cooked): ~150 calories
Bread is relatively moderate in calories, but easy to overconsume due to portion size.
Types of Bread and Their Impact
Different breads affect both calories and satiety:
-
White bread → lower fibre, less filling
-
Wholemeal bread → more fibre, more filling
-
Seeded bread → higher calories, more fats
Choosing the right type depends on your overall diet and goals.
How Bread Fits Into Your Daily Intake
If your daily calorie target is:
-
1500 calories → 1 slice = ~5–7%
-
2000 calories → 1 slice = ~4–5%
Eating multiple slices can quickly increase total calorie intake.
