About these numbers
Bacon is processed meat at its most calorie-dense — 540 kcal per 100g cooked. Per slice (~43 kcal), it's manageable; per 100g serving, it's a meal's worth of calories. The 2015 IARC classification noted processed meats as Group 1 carcinogens for colorectal cancer — but the absolute risk increase is modest at typical consumption (1-2 servings/week).

Frequently asked questions
- How many calories in bacon?
- 1 slice: 43 kcal. 3 slices: 130 kcal. 4 slices: 173 kcal. Per 100g cooked: 540 kcal. Turkey bacon: 27 kcal per slice — about 1/3 the calories.
- Is bacon bad for you?
- In small amounts, neutral for most adults. Processed meat consumption is associated with higher CVD and colorectal cancer at higher intakes (2+ servings/day). 1-3 slices a few times per week likely fine. The "bacon is poison" framing is overstated; the "bacon is health food" framing is also wrong.
- Turkey bacon vs regular bacon?
- Turkey bacon is 60% lower calorie (~27 kcal/slice vs 43 kcal). Texture and flavor differ; some find turkey bacon unsatisfying. For weight loss, turkey bacon saves meaningful calories. For occasional indulgence, regular bacon is fine in measured portions.
- Bacon for weight loss?
- In measured portions. 3 slices (130 kcal) provides 9g protein at moderate calories — fits cut targets. The trap is "a few slices" turning into 6+ slices (260+ kcal). Count strictly.
