Last updated: July 10, 2026
Short answer: one slice of white sandwich bread (about 25 g) hasabout 75 calories, made up of 2.6 g protein, 14 g carbs, and 1 g fat. A slice of whole wheat bread is a touch higher at ~81 caloriesbut adds more protein and fiber. Toasting does not change the calories.
Bread is one of the most-logged foods there is, and the calories are more modest than most people assume — the slice itself is usually 75-81 calories. What pushes a bread-based meal higher is almost always what goes on top or in between: butter, oil, cheese, and spreads. Below are the numbers for common servings so you can log bread accurately.
Bread calories and macros by serving
| Serving | Calories | Protein | Carbs | Fat |
|---|---|---|---|---|
| 1 slice white bread (25 g) | 75 kcal | 2.6 g | 14 g | 1 g |
| 2 slices white bread (50 g) | 150 kcal | 5.2 g | 28 g | 2 g |
| 1 slice whole wheat (28 g) | ~81 kcal | 4 g | — | — |
| 100 g white bread | ~265 kcal | — | — | — |
A slice of white bread carries about 0.8 g of fiber, while whole wheat has roughly 3 g per slice along with more protein — one of the main reasons whole grain bread tends to be more filling. Whole grain versions are also a well-known source of B vitamins and, like many grains, contribute some potassium and iron to your day.
How bread fits your calorie goal
Whether bread helps or hurts your goal comes down to your daily total, not the bread itself. At roughly 75 calories a slice, two slices for a sandwich is about 150 calories before fillings — an easy amount to plan around. Start by finding your target with thecalorie calculator, and if you are losing weight, aim to keep that bread inside a calorie deficit.
For muscle building or higher-protein eating, bread is mostly a carb source — good for energy, but you will want to pair it with a protein like eggs, tuna, or chicken to round out the meal. Whole wheat is the better default because its extra fiber and protein slow digestion and keep you fuller.

Log your bread in seconds
You do not have to weigh every slice. The MyPlate app lets you log bread and everything on it by snapping a photo or scanning the barcode on the loaf, so a sandwich or piece of toast is counted in seconds instead of guessed.

Frequently asked questions
How many calories in one slice of bread?
One slice of white sandwich bread (about 25 g) has roughly 75 calories, with 2.6 g of protein, 14 g of carbs, and 1 g of fat. A slice of whole wheat bread is a little denser at about 81 calories per slice (28 g), but it comes with more protein (around 4 g) and about 3 g of fiber versus under 1 g in white. So "one bread" is usually 75-81 calories depending on the type.
How many calories in two slices of bread for a sandwich?
Two slices of white bread come to about 150 calories (5.2 g protein, 28 g carbs, 2 g fat) before any fillings — that is just the bread. Two slices of whole wheat is closer to 160 calories but adds roughly 6 g of fiber. Remember the calories that really add up in a sandwich are usually the spreads, cheese, and mayo, not the bread itself.
Does toasting bread add calories?
No. Toasting bread does not meaningfully change its calories — a toasted slice of white bread still has about 75 calories. Toasting drives off a little moisture, which is why toast feels lighter and crispier, but the actual energy content stays essentially the same. What changes the number is what you put on the toast, like butter or jam.
Is bread good for weight loss?
Bread can absolutely fit a weight-loss diet — at roughly 75 calories a slice, it is not especially high in calories. What matters is the total: staying in a calorie deficit and watching portions and toppings. Whole wheat bread is the smarter pick because its extra fiber (about 3 g per slice) and protein keep you fuller for longer, which makes it easier to eat less overall.
