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).
