It's no huge secret that Demi Lovato has had some serious issues with her weight. The "Heart Attack" singer who battled an eating disorder and went to a treatment facility back in 2010 has since come a long way. Now, she's a more confident woman -- focusing her efforts on her upcoming self-titled CD and her gig on the X Factor. But something tells me this X Factor spot may not be so good for her, after all.

Rumors are swirling that co-judge Simon Cowell wants Demi to drop 20 pounds over the summer. An insider tells Perez Hilton he's very "supportive of her battles" and wants to support her efforts in a "healthy way."

Of course, Simon's camp says this is total bull and he never said anything of the sort. Either way -- can you imagine!? Telling someone who has successfully moved forward from an eating disorder that they need to drop some weight? That's like telling a former alcoholic they should just TRY one sip of wine to see how it tastes.

It doesn't take much to inspire me to whip out a camera and start snapping photos of my loved ones. There is no need for a special occasion or a big holiday to capture fun family memories. But I recently learned that they can be so much more than that. Those cherished images can actually help your doctors diagnose a serious illness. Check out what to look for:

Everyone told me weight would just magically fall off as I got closer to my wedding day, because when you're stressed, "that's just what happens." Um, not so much. It's more like the reverse for me, thanks to hormones, so I've just been hoping my hard workouts provide stress relief (sounds pretty counterintuitive, huh?). But for many women, stress and difficult emotions often lead to involuntary weight loss. Even if they're going through the roughest times of their lives, they might look thinner than ever, and then we commend them. Ridic!

Eva Longoria spoke with Dr. Oz about the months following her divorce from Tony Parker, and she said it was "the time I got the most compliments, because I was so skinny. I was not eating. I was depressed. I was sad. My diet was coffee." Grrrreat.

With just a matter of a couple of weeks before the Big Day, I've come to realize there are two wacky behaviors people assume all brides-to-be are engaging in. The top two: Stressing out about minor details that have yet to come together and starving herself. While I'm totally guilty of the first, the second blows my mind. Why do we almost assume that someone getting married is on an extreme crash diet? And act like that's just a normal part of planning? It's NOT.

Along with all things wedding mania, from sweating over picking the perfect "YES!" dress to having the perfect DIY touches to choosing a photographic theme worthy of Pinterest, has come brideorexia. It's almost like someone snuck it onto that Knot checklist of pre-wedding to-dos: "Finalize vendor payments, stop eating, proofread programs ..." What the heck!? I honestly cannot think of a more dangerous way of preparing for your wedding day.

Amanda Bynes hasn't seemed right in the head for a while now, so it should really come as no surprise that she's been off and running with even more insane tweets. The latest: She's claiming she has an eating disorder and once again threatening to sue "certain blogs and magazines" for saying she has "a mental illness." She wrote: "They take pictures anytime I've gained weight then write a fake story! ... I have an eating disorder so I have a hard time staying thin." Whaaaa?

The only eating disorder that could cause you to have a hard time staying thin I would guess would be compulsive overeating ... or bulimia, which can involve binging and a slowed metabolism. Either way, it's definitely sad that she's dealing with that. And there's evidence that she may be suffering from body dysmorphic disoder, as well ...

Kendall Jenner, the 17-year-old half-sister of Kim, Khloe, and Kourtney Kardashian, says she's tired of being bullied for looking "anorexic." In a recent interview with Harper’s Bazaar Arabia, Kendall says she's frequently taunted for being too skinny -- and it hurts.

Of course it does. Honestly, whether people are teasing you for being too fat or too skinny, they are insulting your appearance and your body -- both of which you have absolutely no control over to a large extent. It’s personal.

Have you heard of the latest trend in eating disorders? It is male anorexia, nicknamed “manorexia”. Honestly, it’s not actually anything new. It's just that it's been brought into the spotlight by the media recently. And it's about time. Maybe now, anorexia will get the attention it deserves and people will start to fully understand this is a serious problem. It’s not just a teen girl trying to fit into a size 0; it can affect anyone, even men.

The name might sound funny but the disorder can easily be fatal. People seem to think that if you add -orexia to anything these days and it simply suggest that people are over indulging in an activity. But manorexia is a devastating disease and the repercussions include the possibility of death.

There has been a recent boom in the gluten-free market, and much of it has to do with an increase in gluten sensitivity and diagnoses of celiac disease. And it's great that stores are offering more of a selection of foods for people with those conditions.

But recently, doctors have been noticing a rise in the number of people going gluten-free as a lifestyle choice -- namely, to lose weight, much like the reasons some decide to stop eating carbs.

Medically, it’s not really a huge deal because gluten isn't something our bodies need to thrive. I equate it to becoming a vegetarian, because we don't need animal flesh, either -- just the protein it provides. The issue lies within the reasoning behind the gluten-free lifestyle; people are going gluten-free to get thin.
