Food Sensitivities That Can Make You Fat

It's not surprising to hear about Hollywood celebrities on restrictive diets, but lately everyone from Kim Kardashian to Miley Cyrus is coming forward to say not that they won't eat certain foods, but that they can't, due to food sensitivities.  Not to be confused with food allergies, food sensitivities are typically not life-threatening, and sufferers deal with symptoms such as fatigue, headaches, bloating, and GI distress. And in some cases, it can also make you gain weight.

According to nutrition and fitness expert JJ Virgin, co-host of TLC's Freaky Eaters, 70 percent of people have some type of food sensitivity, the most common culprits being dairy, wheat, sugar, corn, soy, peanuts, and eggs. "If a 'sensitive' person were to eat these foods regularly, it would create a reaction that raises insulin and cortisol, both of which make you better at storing fat, especially around the midsection, and it's even harder to burn it off," Virgin says. "This immune reaction also paradoxically makes them crave the very foods that are hurting them thus creating a vicious cycle that is hard to break out of."

The only true way to find out if you have a food sensitivity is an 'elimination diet,' where you cut out these so-called 'troublemaker' foods, and then slowly introduce them back into your diet to see how you react with each one (typically under a doctor's supervision).

These five celebs found out which foods were making them sick—and completely cut them out of their diets!

Celiac Disease: Elisabeth Hasselbeck
Perhaps one of the most vocal on food sensitivities, The View co-host Elisabeth Hasselbeck was so open about her self-diagnosed Celiac Disease (an extreme intolerance for gluten) that she wrote a cookbook on it. Surely other Celiac sufferers like Jennifer Esposito and Emmy Rossum appreciate it!
Dairy, Wheat, and Eggs: Zooey Deschanel
The 32-year old Zooey Deschanel can't stomach dairy, wheat, or eggs. But don't call the New Girl actress insensitive—she reportedly gets 'special' meals delivered to her trailer so no one else has to suffer as a result of her sensitivities.
Gluten Reaction: Miley Cyrus
When teen-star Miley Cyrus seemingly shed all her baby fat, reports surfaced that she may suffer from an eating disorder. In response, Cyrus took to Twitter to dispel rumors and say that her weight loss was actually the result of a lactose and gluten sensitivity.

"Everyone should try no gluten for a week," she tweeted. "The change in your skin, physical, and mental health is amazing!"

Kim Kardashian recently joined Cyrus in the G-free boat, tweeting "Gluten free is the way to be."

Sugar (and More): Gwyneth Paltrow
Life just isn't so sweet for Gwyneth Paltrow. In 2010 the Country Strong actress declared war on sugar and how the entire country should kick our addiction to it, saying "our bodies cannot cope with such an enormous load. [Sugar] gives you an initial high, then you crash, then you crave more, so you consume more sugar. It's this series of highs and lows that provoke unnecessary stress on your adrenals."

She also wrote on her GOOP blog that she took an "in-depth" food sensitivity test, only to learn she also couldn't tolerate dairy, gluten, wheat, corn, or oats. Wonder what Paltrow does eat?

Wheat: Rachel Weisz
Please don't pass the bread basket. Oscar-winning actress Rachel Weisz has publicly stated she can't tolerate wheat, which has been linked to triggering migraines in those who can't digest the grain.
