Working out, eating well, and no results- advice?

Hi all,

First, I apologize if this has already been brought up by someone else, I'm still a bit of a newbie So, basically here's my story. 22 year old student, on the curvy side with most of the unwanted weight in hips and thighs, maintains a pretty healthy diet all year round (tons of fresh veggies like kale, spinach, etc almost every day, high in proteins like chicken breast, tofu, lean beef, good fats like avocado, organic nut butters, and limited carb intake--almost always whole grains, things like steel cut oats, quinoa, whole wheat couscous, etc). I work out 3-4 times a week on a good week (usually strength training with a bit of cardio mixed in, and lots of Jillian Michaels), but usually average out to 2x a week cause of school and work. I've been doing this since August 2012 and have seen absolutely no results (neither in inches or pounds). A friend who's had great success with 4 Hour Body Slow Carb Diet recommended I try that--I've been doing it for 15 days so far (+ working out), and I'm taking Garcinia Camobogia extract and tons of fibre and still no progress, NOT A SINGLE POUND! My calorie intake is 1200-1300.

I know all the "rules" to healthy weight loss, I know all about eating smaller meals more frequently, including good fats, etc, etc. Trust me, I've been researching this stuff for years--and yet nothing seems to be working for me, I'm basically just maintaining my weight.

Is anyone else going through something like this? Anything I'm missing?And on a side note, I've tried upping my calorie intake (for a few months, not just a few weeks, so obviously I wasn't expecting instant results) and no cigar--so eating more clearly isn't going to help. I've also had thyroid levels and blood work done a few weeks ago and it's all good there too.
