Can you have Built Bars on keto? A comprehensive guide

4 min read

With the global protein bar market continuing its rapid expansion, many on a ketogenic diet are curious about whether popular, high-protein snacks like Built Bars can fit into their low-carb lifestyle. While marketed for their high protein and low sugar content, a closer look at the ingredients and net carbs is essential for anyone aiming to maintain ketosis.

Quick Summary

Built Bars can be a viable snack on a ketogenic diet, provided you carefully monitor the net carbs per bar and are aware of the potential effects of sugar alcohols and processed ingredients.

Key Points

  • Check Net Carbs: Most Built Bars have 4-6 grams of net carbs, but always verify the specific flavor's nutrition label to ensure it fits your daily macros.

  • Beware of Sugar Alcohols: While erythritol is generally fine, some flavors may contain maltitol, which can cause blood sugar spikes and digestive issues for sensitive individuals.

  • Not for 'Clean' Keto: Built Bars are a processed food. Those prioritizing whole, unprocessed ingredients may prefer homemade bars or other whole-food snacks.

  • Consider the Puff Bars: Built 'Puff' bars often have added sugars and a different nutritional profile than the standard bars, making them less ideal for strict keto.

  • Occasional Treat, Not Staple: It is best to treat Built Bars as an occasional convenience food rather than a regular staple to maintain ketosis and minimize intake of processed ingredients.

Navigating the Net Carbs and Ingredients

The most critical factor for any ketogenic dieter is the daily carbohydrate limit, typically 20-50 grams, to stay in ketosis. Built Bars are designed with this in mind, often leveraging a net carb calculation that subtracts fiber and sugar alcohols from the total carbohydrates to arrive at a lower, keto-friendly number. Net carbs generally range from 4 to 6 grams per bar for many of their standard flavors. However, not all Built Bar products are created equal. The popular 'Puff' bars, for instance, may contain added sugars and higher carb counts that make them less suitable for a strict keto plan.

Understanding Sugar Alcohols and Their Impact

Built Bars and many other 'keto-friendly' products use sugar alcohols to achieve sweetness without the high carbohydrate load of traditional sugar. The most common in Built Bars are erythritol and sometimes maltitol. Erythritol is generally well-tolerated on keto because it has a glycemic index of zero and is not metabolized by the body. Maltitol, however, can have a more significant impact on blood sugar levels and may cause digestive issues, leading some in the keto community to classify bars containing it as 'dirty keto'. This is a crucial distinction, as a spike in blood sugar from maltitol could potentially knock an individual out of ketosis.

The 'Clean' Keto Perspective

Beyond just the net carb count, many keto practitioners focus on consuming whole, unprocessed foods. From this perspective, protein bars, including Built Bars, are inherently processed and may not align with a 'clean' keto approach. Ingredients like collagen protein, whey protein isolate, glycerin, and natural flavors can be a point of contention for those seeking a diet based on whole foods. This doesn't mean Built Bars are unhealthy, but they may not be the ideal choice for someone prioritizing minimally processed ingredients.

Comparison: Built Bars vs. Other Keto Options

To better understand where Built Bars stand, here's a comparison with other common keto-friendly snacks and bars:

Feature Built Bars Quest Bars Homemade Keto Bars Whole Food Snack (e.g., Nuts)
Net Carbs (approx.) 4–6g 3–5g Varies (often 2–4g) Varies (e.g., 1 oz almonds is ~3g)
Protein Source Whey isolate, collagen Whey isolate, milk protein isolate Varies (e.g., protein powder, collagen) Not applicable
Sweeteners Erythritol, stevia, maltitol (flavor dependent) Erythritol, sucralose Monk fruit, stevia, erythritol Not applicable
Ingredients Processed, some additives Processed, some artificial sweeteners Whole foods, natural sweeteners Minimally processed whole foods
Convenience High (pre-packaged) High (pre-packaged) Low (requires prep time) High (bagged)
Digestive Impact Varies due to sugar alcohols Varies due to sugar alcohols Generally low if using whole foods Generally low

Potential Downsides and Considerations

  • Individual Tolerance: As with any product containing sugar alcohols, individual tolerance can vary dramatically. Some people experience digestive discomfort, gas, or bloating from erythritol or maltitol, especially in larger quantities. A single bar may be fine, but multiple bars could cause issues.
  • Flavor Differences: Not all flavors of Built Bars have the same nutritional profile. It is crucial to check the specific nutrition label for the flavor you are consuming, as total carbohydrates, added sugars, and fiber can differ.
  • Macro Balance: While Built Bars are high in protein, they are not a significant source of the high fat content typically associated with a ketogenic diet. Depending on your other food choices, relying on them too heavily might skew your macro ratio toward protein, which can be converted to glucose through gluconeogenesis if consumed in excess.
  • Highly Processed: If your goal is to eat a 'clean' keto diet with a focus on nutrient-dense, whole foods, a protein bar may not be the best choice. While convenient, these are still processed snacks and should not replace meals or whole-food snacks like nuts, seeds, or avocado.

How to Incorporate Built Bars Responsibly

For those who decide that Built Bars fit into their dietary approach, here are some tips for responsible consumption:

  • Treat as a Treat: View them as an occasional treat or a convenience food rather than a daily staple. This helps control your intake of processed ingredients and sugar alcohols.
  • Use as a Pre or Post-Workout Snack: For those who follow a targeted ketogenic diet (TKD), a small, easily digestible carb source like a Built Bar might be acceptable before or after an intense workout.
  • Monitor Effects: Pay close attention to how your body reacts after eating a Built Bar. If you notice any blood sugar fluctuations or digestive discomfort, you may be sensitive to the ingredients and should seek alternatives.
  • Pair with Fat: Since Built Bars are relatively low in fat, consider pairing one with a high-fat source like a handful of nuts, a keto-friendly shake, or a serving of avocado to better balance your macros.

Conclusion

So, can you have Built Bars on keto? The answer is nuanced. Yes, you can incorporate them, but with a few important caveats. For a less restrictive approach, most standard Built Bar flavors are likely fine in moderation, provided you track your net carbs carefully. For those following a 'cleaner' or more sensitive keto plan, the processed nature and presence of sugar alcohols like maltitol (in some flavors) may be a deal-breaker. The best practice is always to read the nutrition label, understand your individual tolerance for ingredients, and consider Built Bars an occasional convenience rather than a daily necessity.

Frequently Asked Questions

Built Bars can assist with weight loss on keto as they are high in protein, which promotes satiety, and are relatively low in calories (130–180 per bar). However, their effectiveness depends on your overall diet and calorie intake.

Total carbs include all carbohydrates, while net carbs represent the carbs your body actually digests and absorbs. On Built Bars, net carbs are calculated by subtracting dietary fiber and sugar alcohols from the total carbs, as these are not fully digested.

Some individuals are sensitive to sugar alcohols, especially maltitol, which is present in some Built Bar flavors. Overconsumption can lead to digestive discomfort, gas, or bloating.

Built 'Puff' bars are generally less suitable for strict keto. They often contain added sugars and different ingredients compared to the standard Built Bars, potentially making them higher in net carbs.

Excellent whole-food alternatives include nuts and seeds, which provide healthy fats and fiber. You can also make your own homemade keto protein bars using almond flour, coconut oil, and a keto-friendly sweetener.

While low in net carbs, eating a processed bar every day is not recommended for a 'clean' keto diet. It's better to treat them as an occasional convenience and focus on nutrient-dense, whole foods for the majority of your meals.

Always read the nutrition label on the specific bar and flavor you intend to purchase. Look for the lowest possible net carb count and check the ingredients for maltitol or added sugars that might not align with your personal keto standards.
