Matt Damon Says Gluten-Free Diet Helped Him Lose Weight for ‘The Odyssey’
**Weight Loss and Gluten-Free Diets**

Actor Matt Damon credits cutting gluten from his diet with helping him lose weight for his role in director Christopher Nolan's upcoming film "The Odyssey." However, experts caution that there is no scientific evidence to support the claim that a gluten-free diet leads to weight loss.

In an interview, Damon revealed how he achieved his desired physique for the movie. He stated that he made significant changes to his diet by eliminating gluten, which he believes helped him return to his high school weight.

But is cutting gluten really the key to weight loss? According to registered dietitian Shelley Balls, a gluten-free diet may not be necessary or beneficial for most people. "Unless you have celiac disease or non-celiac gluten sensitivity, I don't recommend following a gluten-free diet," she said. "You'll be eliminating potentially healthy foods and spending more money on gluten-free products."

While a gluten-free diet may help decrease the intake of refined grains that can hinder weight loss, there is no scientific evidence to support its use as a weight loss tool. In fact, research suggests that a calorie deficit is still the most effective way to lose weight.

For those living with celiac disease, a gluten-free diet may actually lead to weight gain as the body begins to absorb nutrients more effectively. It's essential to consult with a healthcare professional or registered dietitian before making significant changes to your diet.

Bonnie Taub-Dix, RDN, agrees that Damon's approach worked for him in the short-term, but emphasizes the importance of recognizing that what works for one person may not be suitable for others. "It's essential to consult with a healthcare professional or registered dietitian to create a personalized and balanced dietary plan," she said.

**Healthy Weight Loss Tips** * Consult with a registered dietitian to create a personalized and balanced dietary plan. * Focus on whole, nutrient-dense foods such as fruits, vegetables, lean proteins, and whole grains. * Aim for a calorie deficit through a combination of healthy eating habits and regular physical activity. * Be mindful of refined carbohydrates and processed foods that can hinder weight loss.
