Are Quest Keto Bars Good for Weight Loss?

Because Quest bars are low in calories, sugar and carbs, they may aid in weight loss. They are also high in protein, fat, and fiber, to help keep you feeling full throughout the day so that you’re less likely to overeat.  Unlike bars with Isomalto-oligosaccharide (IMO) fiber, Quest Bars use Soluble Corn Fiber, which won’t spike insulin or raise blood sugar levels.  

There is no need to feel deprived while dieting or avoid sweets completely.  If you are craving chocolate, enjoying a low carb Quest Keto Bar as a snack could help you avoid feeling that sense of deprivation that often leads to failure.  After all, a healthy lifestyle change should be sustainable and that includes treating yourself from time to time.

Are Quest Keto Bars Healthy?

Some Quest bars contain Isomalto-Oligosaccharides (IMO) ingredient is derived from plant sources. However, the ingredient is added only after a lengthy processing method that results in a thick sticky syrup. IMO is not considered a natural fiber and is harder for your body to digest, causing problems with digestion.  Fortunately, Quest is revising its current recipe.  Their Chocolate Chip Cookie Dough Protein bar uses soluble corn fiber, which is better for digestion and avoiding insulin spikes.

Plus, 17 grams of fiber and 20 grams of protein packed into each bar could cause stomach trouble, cramping, and gas.  You might ask, is the protein you’re getting a high-quality protein?  Quest bars use whey protein isolate and milk protein isolate are not exactly natural sources of protein.  These isolates cannot be efficiently broken down by the body in high concentrations.  If you have a sensitive stomach or suffer from digestive issues, these bars might not work for you.

Research shows that Sucralose increases the chances of cancer and digestive diseases.  However, the amount contained in Quest bars is negligible.

Always check the label to make sure you’re choosing a bar with the best ingredients and weigh the pros and cons of each to see which bar best supports your dietary needs and weight loss goals.
