Bread Macros: Complete Nutrition Facts & Calories
Reviewed by Sarah Chen, MS, RD
Bread is a dietary staple that’s been unfairly demonized. Yes, it’s carb-dense. No, it won’t ruin your diet when eaten mindfully. The key is understanding bread macros—which vary significantly between types—and tracking accurately.
This guide breaks down bread macros completely: white vs. whole grain, specialty options, sandwich bread vs. bakery bread, and how to make bread fit any nutrition goal.
Bread Macros: Quick Reference
Here’s what you need to know for common bread types.
White Bread (Enriched)
| Serving | Calories | Protein | Carbs | Fat | Fiber |
|---|---|---|---|---|---|
| 1 slice (30g) | 79 | 2.7g | 15g | 1g | 0.6g |
| 2 slices (60g) | 158 | 5.4g | 30g | 2g | 1.2g |
| 100g | 265 | 9g | 49g | 3.2g | 2.4g |
Whole Wheat Bread
| Serving | Calories | Protein | Carbs | Fat | Fiber |
|---|---|---|---|---|---|
| 1 slice (33g) | 81 | 4g | 14g | 1.1g | 2g |
| 2 slices (66g) | 162 | 8g | 28g | 2.2g | 4g |
| 100g | 247 | 12g | 43g | 3.4g | 6g |
Sourdough Bread
| Serving | Calories | Protein | Carbs | Fat | Fiber |
|---|---|---|---|---|---|
| 1 slice (36g) | 90 | 3.5g | 18g | 0.5g | 1g |
| 2 slices (72g) | 180 | 7g | 36g | 1g | 2g |
Low-Carb/Keto Bread
| Serving | Calories | Protein | Net Carbs | Fat | Fiber |
|---|---|---|---|---|---|
| 1 slice (~28g) | 35-50 | 3-5g | 1-4g | 1-3g | 3-5g |
| 2 slices | 70-100 | 6-10g | 2-8g | 2-6g | 6-10g |
Key insight: A sandwich (2 slices) typically adds 150-180 calories and 28-36g carbs. The bread itself is rarely the calorie problem—it’s what goes on and in it.
Bread Types Compared
Per Slice (Average)
| Type | Calories | Protein | Carbs | Fiber | Notes |
|---|---|---|---|---|---|
| White | 79 | 2.7g | 15g | 0.6g | Most common |
| Whole wheat | 81 | 4g | 14g | 2g | More fiber |
| Multigrain | 80 | 3.5g | 15g | 2g | Seeds add nutrition |
| Rye | 83 | 2.7g | 16g | 2g | Distinctive flavor |
| Sourdough | 90 | 3.5g | 18g | 1g | Fermented |
| Pumpernickel | 65 | 2g | 12g | 2g | Dense, dark |
| Brioche | 130 | 3.5g | 15g | 0.5g | Buttery, sweet |
| Ciabatta | 130 | 4g | 25g | 1g | Larger, airier |
| Baguette (2” piece) | 140 | 5g | 28g | 1g | Dense crust |
| Ezekiel/Sprouted | 80 | 4g | 15g | 3g | Sprouted grains |
Why Whole Grain Is Better
White vs. Whole Wheat:
| Factor | White | Whole Wheat | Difference |
|---|---|---|---|
| Calories | 79 | 81 | +2 (negligible) |
| Fiber | 0.6g | 2g | +233% |
| Protein | 2.7g | 4g | +48% |
| Glycemic Index | High (75) | Moderate (69) | Better for blood sugar |
Real benefits of whole grain:
- More fiber = more satiety
- Lower blood sugar spikes
- More vitamins and minerals
- Feeling fuller longer
The catch: Calories are nearly identical. Whole grain isn’t a weight-loss solution—it’s a modest nutritional upgrade.
The Slice Size Problem
Not all slices are created equal:
Slice Weight Variations
| Bread Type | Typical Slice Weight | Calories/Slice |
|---|---|---|
| Thin-sliced | 23-25g | 60-70 |
| Regular | 28-32g | 75-90 |
| Thick-sliced | 38-45g | 100-130 |
| Artisan/bakery | 40-60g | 110-170 |
| Hot dog/burger buns | 45-55g | 120-150 |
| Bagel | 85-110g | 240-300 |
The tracking trap: Logging “1 slice bread” could mean 60 or 130 calories depending on the slice.
Fix: Check your bread’s nutrition label for the specific serving weight, or weigh slices directly.
Low-Carb and Keto Bread Options
For those limiting carbs, several options exist:
Commercial Low-Carb Breads
| Brand | Calories | Net Carbs | Protein | Notes |
|---|---|---|---|---|
| Sola Bread | 35 | 1g | 3g | Widely available |
| Franz Keto | 40 | 0g | 5g | Very low carb |
| Aldi L’Oven Fresh Keto | 40 | 1g | 5g | Budget option |
| Thin Slim Zero Carb | 45 | 0g | 7g | Online mainly |
| Dave’s Killer 21 Grain Thin | 60 | 9g | 5g | Not keto, but lower |
| Carbonaut | 80 | 2g | 7g | Better texture |
Low-Carb Bread Alternatives
| Alternative | Calories | Net Carbs | Notes |
|---|---|---|---|
| Lettuce wrap | 5 | 0.5g | Zero bread texture |
| Cheese wrap | 90 | 0g | Great for keto |
| Egg wrap | 90 | 1g | High protein |
| Cloud bread | 45 | 1g | Light, airy |
| Coconut flour bread | 100 | 3g | Homemade option |
Are Low-Carb Breads Worth It?
Pros:
- 10-15g fewer carbs per slice
- Allow sandwiches on keto
- Satisfies bread cravings
Cons:
- Often more expensive
- Texture can be off (dense, gummy)
- High in fiber (can cause digestive issues)
- Some taste very different from bread
Verdict: If you’re strictly keto and miss sandwiches, they work. For moderate low-carb, regular bread in small portions might satisfy better.
Making Bread Work for Different Diets
Weight Loss/Cutting
Bread isn’t the enemy—portions and toppings are:
The math:
- 2 slices bread = 160 calories
- 2 tbsp butter = 204 calories
- The butter has more calories than the bread!
Cutting-friendly sandwich:
| Ingredient | Calories |
|---|---|
| 2 slices whole wheat | 162 |
| 4 oz turkey breast | 120 |
| Mustard | 5 |
| Lettuce, tomato | 10 |
| Total | 297 |
Calorie traps to avoid:
- Mayo (2 tbsp = 180 cal)
- Cheese (1 slice = 70-110 cal)
- Butter (1 tbsp = 102 cal)
- “Special sauce” (often 100+ cal)
Low-Carb Diet (Non-Keto)
On a moderate low-carb diet (50-100g carbs/day):
| Bread Approach | Carbs |
|---|---|
| 2 slices regular bread | 30g |
| 2 slices low-carb bread | 4-10g |
| 1 slice + open-face | 15g |
| Lettuce wrap | 0.5g |
Strategy: Save bread carbs for when you really want them. One sandwich uses 30g carbs—about 30-50% of a moderate low-carb day.
High-Protein Diet
Regular bread has modest protein (~3g/slice). Boost it:
High-protein sandwich strategies:
| Ingredient | Protein |
|---|---|
| 2 slices Ezekiel bread | 8g |
| 4 oz chicken breast | 35g |
| 1 oz cheese | 7g |
| Total | 50g |
Protein-enhanced breads:
- Ezekiel/Sprouted: 4-5g per slice
- Dave’s Killer: 5g per slice
- P28 Protein Bread: 14g per slice (specialty)
Keto/Strict Low-Carb
Regular bread doesn’t fit strict keto. Options:
- Low-carb breads: 0-4g net carbs per slice
- Alternatives: Lettuce wraps, cheese wraps, cloud bread
- Skip it: Not every meal needs bread
Keto sandwich:
| Ingredient | Calories | Net Carbs |
|---|---|---|
| 2 slices Sola bread | 70 | 2g |
| 3 oz ham | 90 | 1g |
| 1 oz cheese | 110 | 0g |
| Mayo (1 tbsp) | 90 | 0g |
| Total | 360 | 3g |
Specialty Breads Macros
Bakery and Artisan Breads
| Type | Serving | Calories | Carbs |
|---|---|---|---|
| French bread (2” slice) | 40g | 110 | 21g |
| Italian loaf (2” slice) | 40g | 105 | 20g |
| Focaccia (3x3” piece) | 60g | 170 | 26g |
| Ciabatta roll | 85g | 220 | 44g |
| Croissant | 60g | 270 | 26g |
| Pretzel roll | 85g | 230 | 46g |
Breakfast Breads
| Type | Serving | Calories | Carbs | Notes |
|---|---|---|---|---|
| Bagel (medium) | 95g | 270 | 53g | Deceptively calorie-dense |
| English muffin | 57g | 130 | 25g | Better portion control |
| Toast (white) | 30g | 79 | 15g | Same as untoasted |
| Waffle (frozen) | 35g | 95 | 15g | Often lower than expected |
| Pancake (4” diameter) | 40g | 90 | 15g | Similar to bread |
The Bagel Problem
Bagels deserve special attention:
Bagel vs. Bread:
| 2 Slices Bread | 1 Bagel | |
|---|---|---|
| Weight | 60g | 95-110g |
| Calories | 160 | 270-300 |
| Carbs | 30g | 53-58g |
One bagel equals nearly 4 slices of bread. If you love bagels, consider:
- Bagel thins (110 calories)
- Scooping out the middle
- Eating half
- Tracking accurately

Bread Meal Prep Tips
Freezing Bread
Bread freezes extremely well:
- Separate slices with parchment (optional)
- Place in freezer bag, remove air
- Freeze up to 3 months
- Toast directly from frozen
Why freeze: Prevents mold/staleness, allows bulk buying, always available.
Pre-Made Sandwiches
Prep ahead:
- Make sandwiches 1-2 days ahead
- Store in fridge (not freezer)
- Avoid wet ingredients (tomato, lettuce) until eating
- Pack those separately
Storage Guidelines
| Type | Room Temperature | Refrigerator | Freezer |
|---|---|---|---|
| Commercial bread | 5-7 days | Not recommended* | 3 months |
| Homemade bread | 3-4 days | 7 days | 3 months |
| Low-carb bread | Check label | Often required | 2 months |
*Refrigerating bread can make it stale faster (starch retrogradation)
Common Bread Tracking Mistakes
Mistake #1: Ignoring Slice Size Variation
“1 slice bread” can mean 60-130 calories.
Fix: Check your bread’s label for slice weight. Weigh if unsure.
Mistake #2: Forgetting Spreads and Toppings
The bread: 80 calories The butter, mayo, cheese: 300+ calories
Fix: Track EVERYTHING on the bread, not just the bread.
Mistake #3: Underestimating Bakery Bread
That thick artisan slice is probably 120-150 calories, not the 80 you logged.
Fix: Weigh bakery bread or estimate conservatively.
Mistake #4: “Healthy Bread” = Fewer Calories
Whole wheat, multigrain, and “ancient grain” breads have the same (or slightly more) calories as white bread.
Fix: Choose whole grain for fiber and satiety, not calorie savings.
Mistake #5: The Bagel Blind Spot
Treating a bagel like “bread” when it’s 3x the calories.
Fix: Know that one bagel = nearly 4 slices of bread.
The Bottom Line
Bread is a straightforward carb source:
- 79-90 calories per slice — Most regular bread
- 14-18g carbs per slice — Adds up in sandwiches
- 2-4g protein per slice — Modest contribution
- Whole grain advantage: More fiber, not fewer calories
Key tracking rules:
- Check slice weight on YOUR bread’s label
- Track all spreads and toppings
- Bagels = 3-4 slices worth of bread
- Low-carb bread works for keto; not needed otherwise
Bread can fit any diet when portioned and tracked accurately. The villain isn’t bread itself—it’s the butter, mayo, cheese, and oversized portions that often accompany it.
