Bacon Calories Calculator
Bacon calories range from 42 calories per grilled rasher to over 600 kcal per 100g for crispy fried strips. The cooking method, fat content and cut of bacon change the calorie count considerably.
Bacon Nutrition Overview
Bacon is a cured and smoked pork product popular across the USA and UK as a breakfast staple and ingredient in sandwiches, salads and cooked dishes. Calorie content varies significantly by cut (back vs streaky), cooking method (grilled vs fried), and how much fat is rendered during cooking. Grilling removes more fat than frying, making grilled bacon meaningfully lower in calories than fried versions.

Best for fitness goals
For weight loss, choose back bacon over streaky, grill rather than fry, and limit to 2 rashers. For muscle gain, bacon is high in protein (about 12g per 50g serving) but also high in sodium and saturated fat — use it as a flavour addition rather than a primary protein source.
Bacon Calories — Complete Breakdown
Raw bacon is composed of fat, protein and water. When cooked, water is driven off and fat partially renders, concentrating the remaining calories. Crispy bacon has higher calories per gram than lightly cooked bacon because more water has been removed. In the UK, "bacon" typically refers to back bacon (from the loin), which has a leaner profile than American-style streaky bacon (from the belly). This distinction matters for calorie tracking: a UK rasher and a USA bacon strip have quite different calorie profiles.
Bacon Calories by Cut and Cooking Method
| Type | Weight | Calories | Protein | Fat |
|---|---|---|---|---|
| Back bacon rasher (grilled, UK) | 28g | ~48 kcal | 6.3g | 2.4g |
| Streaky bacon strip (cooked, USA) | 8g | ~43 kcal | 3g | 3.3g |
| 2 back rashers (grilled) | 56g | ~96 kcal | 12.6g | 4.8g |
| 3 back rashers (grilled) | 84g | ~145 kcal | 18.9g | 7.2g |
| Streaky bacon, 3 strips (crispy) | 24g | ~129 kcal | 9g | 9.9g |
| Turkey bacon, 2 strips | 30g | ~68 kcal | 7.8g | 3.6g |
| Bacon per 100g (back, grilled) | 100g | ~173 kcal | 22.5g | 8.7g |
Grilled vs Fried Bacon — Calorie Difference
Grilling bacon drains rendered fat away from the meat, resulting in approximately 20–35% fewer calories than frying the same rashers in their own fat or in oil. When you grill bacon on a rack and the fat drips away, a portion that would be 145 kcal fried is closer to 95–110 kcal grilled. For calorie-conscious eating, the grill is the most effective cooking method for reducing bacon calories without eliminating it from the meal.
Bacon in a Weight-Loss Diet
Bacon is not incompatible with a weight-loss diet, but it should be treated as a flavour addition rather than a calorie foundation. Two grilled back rashers add approximately 96 calories and 12.6g protein — a useful protein contribution at a manageable calorie cost. The concern with bacon in a weight-loss context is primarily its companions: a full café breakfast with fried eggs, sausages, beans and toast alongside bacon can total 800–1,200 calories. Managing the rest of the plate is more impactful than eliminating bacon specifically.
Sodium content is also worth considering: one rasher typically contains 350–500mg sodium, and eating 3–4 rashers with other processed items can push sodium intake well above the 2,300mg daily recommendation, which contributes to water retention and temporarily inflated scale weight.
Bacon for Protein Intake
Bacon is a meaningful protein source. Grilled back bacon provides approximately 22g protein per 100g cooked weight, comparable to chicken. However, it also contains significant saturated fat and sodium, which limits how much is advisable as a regular protein source. For gym-focused users tracking protein, bacon works best as an addition to eggs or in a protein-focused meal rather than as the primary protein source. Turkey bacon provides similar protein with approximately 35% fewer calories and lower saturated fat.
Healthy Alternative Tips
🥗 Lower Calorie Alternative: Turkey bacon provides 34 calories per strip (vs ~43 for streaky pork) with similar protein. Sliced prosciutto (2 thin slices, 14g) is another lean alternative at 46 calories with 6g protein and a strong flavour from a small quantity.
💪 Higher Protein Alternative: Canadian bacon (back bacon, lean cut) provides the same rasher-style format with significantly less fat — about 30 calories per slice vs 48 for standard back bacon, with similar protein at 5–6g per slice.
🔄 Smarter Swap: Grill bacon on a wire rack instead of frying. The fat drains away instead of re-absorbing into the meat. This alone reduces a 3-rasher portion from ~180 to ~120 calories — a 33% calorie reduction with no taste compromise.

FAQs
How many calories in a rasher of bacon?
A standard grilled UK back bacon rasher (about 28g cooked) contains approximately 48 calories. Two rashers are ~96 calories. An American streaky bacon strip (8g, crispy) contains 37–45 calories per strip.
How many calories in bacon per 100g?
Grilled back bacon: approximately 173 kcal per 100g. Fried streaky bacon: approximately 540–600 kcal per 100g raw (the high value reflects fat content; note that raw bacon is much heavier than cooked weight).
Is grilled bacon lower in calories than fried?
Yes, grilling on a rack allows fat to drain away, reducing calories by 20–35% compared to frying in its own fat or oil. For a typical 3-rasher portion, this is a difference of approximately 40–60 calories.
Is turkey bacon lower in calories than pork bacon?
Yes — turkey bacon typically contains 30–40% fewer calories than pork bacon. Two strips of turkey bacon run about 60–70 calories vs 85–100 calories for two pork streaky strips. Turkey bacon is also lower in saturated fat.
