Can Going Gluten-Free Help You Lose Weight?
Cutting out gluten is all the rage—but if you don’t do it right you could end up gaining weight instead. By Melissa Romero

Relatively unknown until the past few years, the gluten-free diet has become increasingly trendy, due in no small part to professional athletes and stars attributing their lean bodies and impressive performances to cutting gluten. And now, thanks to teen performer Miley Cyrus's recent tweet that her skinny figure is due to gluten allergies, many wonder if going gluten-free is an ideal way to lose weight. 

Not quite, says registered dietitian and celiac disease expert Cheryl Harris. Before you trash every loaf of bread and box of pasta in your pantry, know this: Research shows that most people who go gluten-free actually gain a substantial amount of weight. 

The reason someone like Cyrus who has wheat or gluten allergy has lost weight, Harris says, is because "they've cut out large quantities of food or processed food altogether."

"If anyone were to say, 'I'm going to give up all sandwiches and pastries,' then they would absolutely lose weight," she says. "But that has nothing to do with gluten."

People who suffer from celiac disease also tend to lose weight because "patients are unable to absorb nutrients in the food they eat, so they lose weight even when they aren't trying to," says Vanessa Maltin Weisbrod, executive editor of Delight Gluten-Free Magazine

Adds Heather Aitken-Cade of Celiac Family, once they start a gluten-free diet, weight gain occurs as their body heals and is able to absorb nutrients and calories that once passed through. 

Those who truly suffer from gluten or wheat allergies, celiac disease, irritable bowel syndrome, or autoimmune diseases almost always feel better on a balanced, gluten-free diet. But for those who don't have a gluten allergy or celiac disease, Weizbrod warns, "You can't just walk into Whole Foods, buy a ton of gluten-free cakes, cookies, crackers, chips, and treats and consider them diet food."

Those who raid the gluten-free aisles are going about it the wrong way, adds Mint fitness director Vanessa Hailes. "There's the population of diet-crazed individuals who think gluten-free screams 'no carbs!' What they don't realize is that there are still carbs, calories, and sugar in gluten-free products."

They might even end up eating greater quantities of the gluten-free products, "possibly doubling or even tripling their caloric intake, which will prevent weight loss and lead to weight gain," Hailes adds.

But then there are athletes like pro tennis star Novak Djokovic, who switched to a gluten-free diet last year and later won the US Open. He credited his stellar performance to his dietary change, which he made after a nutritionist said he was allergic to gluten. So could eliminating gluten have the same effect for other people?

Athletes may certainly see positive results by going gluten-free, but for the same reasons most people's health improves when they go about it the right way, says Weisbrod: They maintain a balanced, natural diet that excludes processed foods while including vegetables, fresh fruits, fish, meats, and whole grains.

In the end, it doesn't hurt to eliminate gluten from one's diet, but only if it's for the right reasons. Harris reminds those looking to go gluten-free that only 6 percent of the population is gluten-sensitive, and 1 percent suffers from celiac disease. That means 93 percent of the population doesn't necessarily need to give up gluten.

"It may be worth a try," says Harris, "but it's not for everyone."

    I have completely eliminated IBS by going gluten free. I do not find it difficult because I can still enjoy potatoes and rice (in limited quantities) and I feel so much better. I avoid sugar, but have not gone crazy about it.

  • I lost five pounds the first few days on a gluten-free diet and I still drank my tea with sugar. I replaced bread/pasta with potatoes and rice, so I didn't really reduce the amount of carbs I took in, I just didn't eat anything with gluten. This has been a great diet for me. I feel better than I've ever felt, I don't get headaches or stomach aches anymore and I feel like I have more energy. I have kept the weight off without even trying (haven't been to the gym in three months). I even still have a regular Coke every now and then (I know Coke is terrible, I love it anyway). I am now the weight I was when I was 16 and I couldn't be happier.

  • Gluten is an important part of our diet and one should really consider not cutting on anything. It is a matter of balance.

    Why is gluten an important part of our diet? What is your basis for that? Read 'Wheat Belly' and you'll think otherwise. I've lost 5 pounds since I started 2 months ago, and have been losing about .2 pounds a day now (my scale is on .2 increments). Also, I lost the arthritic pain I had in my fingers and knees.

    Some people feel like they have to say something about every thing... Kava, you're out of your realm here. Gluten is not a needed nutrient.
