Gluten-free diets have gained popularity in recent years with many people opting for them as a healthier lifestyle choice.

However, a recent study published in the journal Nutrients suggests that gluten-free diets may actually increase the risk of obesity. This article will explore the research behind this claim and discuss the implications of a gluten-free diet on weight gain.

What is Gluten?

Gluten is a protein found in wheat, rye and barley. It is responsible for giving baked goods their elasticity and chewiness. Gluten-free diets exclude all foods and products that contain gluten.

This means that items such as breads, pastas, crackers, and cereals must be avoided or substituted for gluten-free options.

The Link between Gluten and Obesity

The Nutrients study referenced above found that gluten-free diets may increase the risk of obesity.

The researchers analyzed the diets of over 7000 adults and found that those on a gluten-free diet had higher body mass indexes (BMI) than those who consumed gluten-containing foods. BMIs of those on gluten-free diets were, on average, 2 points higher than those who ate gluten. This translates to an average weight gain of approximately 4.5 kilograms (9.9 pounds) for someone who is 5’6″ tall.

Why Does Gluten-Free Increase Obesity?

One theory behind the link between gluten-free diets and obesity is that gluten-free foods are often higher in calories than their gluten-containing counterparts. Many gluten-free products add extra sugar or fat to improve taste and texture.

Additionally, many gluten-free products have less fiber than their gluten-containing rivals, which can lead to increased hunger and overeating.

Other Concerns with Gluten-Free Diets

In addition to the potential for weight gain, there are other concerns with a gluten-free diet. For example, those who follow a gluten-free diet may miss out on important nutrients found in foods that contain gluten, such as B vitamins, iron, and fiber.

These nutrients are important for maintaining a healthy body and a deficiency can lead to a range of health issues, such as anemia, fatigue, and digestive problems.

Who Should Follow a Gluten-Free Diet?

While gluten-free diets have become increasingly popular, they are not appropriate for everyone. Those with celiac disease, non-celiac gluten sensitivity, or wheat allergies must strictly avoid gluten in their diets.

For these individuals, a gluten-free diet is necessary for maintaining their health. However, for those who do not have a medical reason to avoid gluten, a balanced diet that includes whole grains is recommended.

Conclusion

The research suggests that gluten-free diets may increase the risk of obesity due to higher calorie intake and lower fiber content. Additionally, those on a gluten-free diet may miss out on important nutrients found in foods containing gluten.

While a gluten-free diet is necessary for those with celiac disease or gluten sensitivity, for most people a balanced diet that includes whole grains is recommended for optimal health.
