It's an age old tale:

Girl gets hooked on drugs and checks into rehab.  Girl gets clean and gains weight.  Girl loses weight and just can't figure out how to gain it back.  Girl checks back into rehab and rumors spread like wildfire about girl having a gastric bypass surgery reversal.

OK, so maybe it's not age old but it's definitely a tale worth noting.

For all those out there having issues gaining weight, it would be easy for everyone else to say, "Oh, go eat a donut already!"  But sometimes it is just not that easy, so for some healthy tips on how to put weight on safely,

A good rule of thumb is adding 3500 calories to your diet over the course of a week is equivalent to gaining one pound.  (Gaining more than one pound a week can be detrimental to your health.)

Say you are like Nicole and about 5'2" and 25 years old with a small build, an ideal weight should be at or around 108-121 lbs.  This means that ideally you should be eating somewhere around 1600-2000 calories per day, depending on your activity level.  One way to put some pounds on would be to add about 500 calories per day to your daily caloric intake (bringing you to the additional 3500 a week).  The key to safe weight gain is doing it in a healthy way.  For example, you could eat several Krispie Creams and get to your 500 calorie goal rather quickly, but then you may be looking at some health risks down the line (high cholesterol, etc).

Fit's tip:  Raw nuts and fruit juices are a great way to get more calories in a healthy way.

And, like Nicole, always consult your doctor before beginning a new diet.

If you've been to a SoulCycle class, you know what to expect:  a dark room, music on blast, and one happy, chatty instructor who peddles at superhuman speed while you desperately try to keep up.  The new Hulu show Casual knows your struggle;  in it, first-timer Valerie's facial expressions — and off-the-beat pedaling — say it all.  If you've ever been the newbie in an indoor cycling class, you'll be able to relate to this hilarious clip.

When you're a dedicated yogi, it can feel like everything somehow relates back to your practice!  As a brand-new student, you can't even begin to imagine the ways your yoga practice evolves and how it shapes and changes your day-to-day life — even outside the studio.  Here's what you have to look forward to ... or watch out for.

Women spend so much time thinking about their bodies, wishing they were smaller here, larger here, never ever happy with what they've got.  It's time to love your bodies already, because if you don't, hey, there's someone out there who will.  This monologue from The Pete Holmes Show is spot-on, but also NSFW.  Enjoy!
