I've never had any success with calorie counting. My problem is that it makes me way MORE obsessed with food and I'm always looking for ways to fill in th extra calories or I'm just thinking about food all the time, in general, and then eat more.
I've done somewhat of an exchange plan that a nutritionist gave me but mostly I just try to eat well (lots of veggies, protein, and whole grains, no sugar). I've experimented enough to know when my body feels the fullest+foods that give me more energy. Then again, I've been at this for over 1.5 years so I've had plenty of time to iron out most of the kinks (unfortunately new ones always show up, though!).
Like others mentioned, though, the closer you get to goal the harder it'S going to be to lose. You already have a fairly low body weight for your height so realistically it makes much more sense to focus on inches loss. Actually, if you just worked on heavy weight lifting (and increased your calories some through protein) you might even see changes more quickly in terms of inches (and isn't that what matters most in the long run?

).
I know some really need calorie counting to hold them accountable but I'm not that type of person. For me I just need to avoid trigger foods and eat healthy food and I can pay attention to my hunger/full signals and do fine. Ultimately you have to do what works best for you.
