Does Bacon Break a Fast? The Surprising Truth

Bacon has a controversial reputation in the fasting world. Many believe that eating bacon will instantly break your fast due to its high fat and protein content. But is this really true? The answer is more nuanced than you might think. In this article, we’ll examine the science behind how bacon impacts fasting and help you determine if it can be part of your intermittent fasting plan.

What Happens During Fasting

Before we dive into bacon specifically let’s review what happens in your body when you fast.

During a fast, your body is in a catabolic state. This means it has switched from burning glucose (sugar) to burning fat and ketones for fuel through a process called ketogenesis. To trigger ketogenesis you need to restrict both calories and carbohydrates. Most experts define a true fast as consuming only water, black coffee, and tea.

How Food Impacts Fasting

Any food or drink besides plain water will have some impact on your fasting state Even black coffee and tea stimulate digestion and metabolism to a small degree So the real question isn’t “does this break my fast” but rather “how much does this disrupt my fasted state?”

Foods that produce a significant insulin response tend to disrupt fasting the most. Insulin is the key hormone released when you eat to shuttle nutrients into cells. Spiking insulin moves the body out of its catabolic fat-burning mode.

Protein rich foods like bacon may not raise insulin as much as pure carbohydrates. But they still require digestive enzymes and stimulate metabolic processes. So while bacon may not “break” a fast it likely alters your fasted state to some degree.

Evaluating Bacon in Fasting Diets

Now let’s focus specifically on bacon and how it fits into various fasting protocols:

Intermittent Fasting

During a 16:8 style fast, the goal is to go 16 hours with little or no calories to achieve a long enough fasting window for fat burning benefits. Having a few bites of bacon towards the end of your fast technically breaks the fast. But it likely doesn’t ruin the entire purpose since you’ve already been fasting for 15+ hours.

Most people following 16:8 intermittent fasting don’t stress about having cream in their coffee or a few bites of food towards their fasting window. While this may not be a 100% clean fast, it can still yield substantial benefits.

Alternate Day Fasting

During alternate day fasting, you severely restrict calories one day (<500 calories) then eat freely the next. The goal of the fasting days is to achieve a prolonged fasted state to deplete glycogen stores and promote ketosis. Even a small amount of bacon could interfere with this process by providing protein and fat. It’s best to avoid it until your feeding window.

Extended Fasting

For longer fasts of 24-48 hours, consumption of any protein or fat will break your fasted state. During extended fasting, ketone production peaks at around 2 days for most people. Consuming bacon would halt ketogenesis and reset the clock. It’s best saved until you decide to break your fast.

Keto Diets

On keto, carbs are strictly limited to under 20-50 grams per day to maintain ketosis. Protein is also moderated. Bacon can be incorporated as a fat source but eating too much may suppress ketosis. Limit bacon to 1-2 servings per day and focus on fattier cuts.

The Verdict on Bacon and Fasting Diets

Based on the evidence, here are some guidelines on incorporating bacon into a fasting regimen:

• Bacon should be avoided completely during alternate day and extended fasting windows
• Limit bacon during keto diets and focus on fattier cuts
• For intermittent fasts <24 hours, a few bites of bacon towards the end of your fast is unlikely to negatively impact your results
• For best results across any fasting plan, wait to eat bacon until your feeding window

The most important factor is monitoring your body and results. If you feel bacon is stalling your progress, avoid it during your fasts. But you may be able to incorporate it in moderation, depending on your fasting regimen.

At the end of the day, fasting requires some flexibility and experimentation to find the approach that fits your lifestyle and goals. While bacon does technically break a fast, a little now and then likely won’t sabotage your fat burning efforts. Pay attention to how your body responds and adjust your bacon consumption accordingly.

Fasting Tips for Incorporating Bacon

Here are some tips for working bacon into your intermittent fasting or keto meal plan:

• Choose fattier cuts of bacon. Look for thick sliced, uncured bacon with plenty of fat. This will provide more satiety and fat burning fuel.

• Avoid bacon cured with sugar. Read labels and pick natural bacon without added sugars.

• Eat mindfully and track serving sizes. It’s easy to overeat bacon, so weigh 3-4 strips as a proper serving.

• Pair bacon with fibrous veggies or greens. This increases satiety and balances the meal.

• Bake your bacon. Baking allows the fat to cook out, resulting in crunchier, lower calorie bacon you can crumble on salads.

• Use bacon fat for cooking. Save excess bacon grease to cook your eggs or roast vegetables in.

• Try turkey or vegetarian bacon. For a lower fat option look for turkey or soy-based bacon substitutes.

• Add crumbled bacon as a topping. Use it to garnish Brussels sprouts, baked potatoes, omelets, cheese boards and more.

• Make bacon the star. Crumble it on a taco salad, put it in an omelet or wrap it around scallops or chicken breasts.

• Mix it into dips and sauces. Crumble bacon into your ranch dressing, chip dip or savory smoothies.

With a little creativity, you can work cured pork belly into your intermittent fasting or keto low carb meal plan. Just be mindful of portions and save indulging in bacon for your eating window when possible.

The Takeaway
