# Really, how many calories are in Bacon?!?

OK, so I am trying to enter my food into a website for logging, because I keep sabotaging my efforts by eating to much. And say this morning I ate 4 slices of bacon. For the hell of it I weighed them on my little food scale. 100g Fine I thought. So I put 100g bacon into the logger and it says 540 calories?! I put in 4 thick slices of bacon and it says 245 calories. What the? So I went and checked another site just to check and the same results came up. Apparently, 4 slices of bacon is not meant to weigh anywhere around 100g. By mine did. SO, is 100g of bacon really 540 calories?

I've encountered the same kind of nonsense. Here is what makes sense to me. Pork is 150 calories per 100 grams. If bacon comes from a pig, then it is pork, and bacon is 150 calories per 100 grams. Often the producer will cure the pork with sugar and other ingredients that can add to the calorie count. So I read the label and I get just the good stuff. If you have brought home some sugar-laden bacon, then you have to increase the calorie count by quite a lot. I think that's where the 245 calories and 540 calories and other wild numbers come from. You have to get the calorie count from the label on the package, because it varies from one kind of bacon to another. The compilers of your calorie-looker-upper probably measured sugared bacon, because that's what "everybody" eats. You can get the same caloric effect, but probably with better flavor, by getting unsugared bacon and pouring maple syrup or honey on it. But I digress. If you get unsugared bacon, figure 4 strips per 100g, or 25g and 40 calories per strip. If the bacon seems especially thin- or thick-sliced, then you can jigger the numbers to suit. I usually make no adjustment, myself, because I'm prone to lying to myself when I fiddle with the numbers. Anyway, finding unsugared bacon can require some exploring, and if you can't find it, then I would say you are better off with a thin-sliced pork chop. Pour molasses on your pork chop if you want to boost the calorie count.

Does it matter? Why not eat to satiation and supplement properly? I wouldn't calorie count. Gary Taubes wrote about Why We Get Fat and showed the type of calorie - fat, protein, and carbohydrate matters. Eat a variety of pastured animal proteins and fats, wild fish (with skin), and ideally local/organic produce, with some nuts. Depending on your situation, if you can tolerate it - you could have raw dairy, or pasteurized grass-fed butter/ghee, nightshades, dark chocolate 80%+.

Well, if you figure that protein is 4 kcal/gram and fat is 9 kcal/gram , one could estimate that cooked bacon would come out at about 5-7 kcal/gram, roughly.

So, I would guess that 100 grams of cooked bacon would equate to roughly 500-700 kcal, depending on the ratio of protein/fat. So, 540 sounds reasonable.

You want the estimate that is for 4 cooked slices, which has a very different profile than an uncooked slice.

I reserve my bacon fat (when I cook it plainly), so when I use that, I add "1 tbsp of bacon grease" as needed.

It really depends on the bacon. Back bacon is much lower in fat and higher in protein than belly bacon, and even with belly bacon is depends on where from the belly it's taken. I buy a thick uncured bacon that doesn't shrink very much when I cook it, which is an indication that it's relatively lean as bacon goes.

Also, some calorie counters may not take into account the amount of fat that gets cooked off, so be sure to check on that. Is there an option to choose cooked or raw bacon? Have you measured the bacon after it's cooked to determine its "cooked" weight? I guarantee it's lower once you've drained off the fat (and stored it to cook with later, of course). So, it they're supplying the calorie count for 100g of cooked bacon, and you're entering its precooked weight, yeah, your numbers are going to be off.

The weight will depend on how much fat you render out of it. Which of course affects the calorie count.

I always go with grams when calculating the numbers. I have a big spreadsheet of the staples I eat that has everything worked out to the gram. Amounts like "1 slice" are useless. If your bacon comes in a package, you could go with the manufacture's label.

With that said though, I think it would be impossible to calculate bacon because the fat/meat ratios vary so much per batch.

Pretty much. WolframAlpha.com say 534 calories. One tablespoon of fat is 120 calories, and bacon is more than half fat, so it will register as pretty high in the calorie department. This doesn't necessarily mean bacon will sabotage all your efforts. Fat and protein are more satiating than other, lower calorie foods, so you may find it easier to meet your calorie target with the bacon rather than without it.

If you're not drinking the fat after you fry your bacon, the calorie count won't be too accurate.
