Have you considered that you may not be eating enough?   Strict calorie restriction can work against you sometimes.

 

I would suggest seeing a dietitian, too, that specializes in sports nutrition.  Could help you figure out the right balance of calories for weight loss and also maintaining your exercise routine (which is really a difficult balance to find).

With all the training you put in, I can almost guarantee you aren't eating enough.

There is a table in the book that suggests a recommended carb intake based on hours/week of training.  I'm not sure how many hours per week you are putting in, but at 11-14 hrs/week, for example, you should be eating 8-9g carbs/kg of body weight (ideal race weight).  So a man whose ideal race weight is 70 kg should be eating 595g of carbs daily, or 2,380 calories worth - of just carbs!

Hipfan, give me a break... I'm sure you're as lean as can be. You're probably very muscular. You do more than just running, right? You do strength work as well, don't you? I think that if you want to be a bit lighter, you'll have to cut down somewhat on the upper body work. Maybe replace with more running? How many hours per week do you run/workout now? Still on the crazy schedule?

I've cut down on the weights, currently running around 70 mpw give or take, and doing about 6-7 gym classes a week though now mostly Power Cycle classes and Cardio Bootcamps. It sure as heck hasn't affected my energy level as I'm hyper as I've ever been and in fact I got 3 new PR's in the month of June as well!

Oski - I have tried to eat a little more, but it really quickly shows up on the scale. A good balance for me is easily under 2000 calories, even on days like last Saturday when I ran 25+ total miles in the Las Vegas heat.

I eat lots and lots of fast food, but don't seem to be running any faster. 

Seriously, I dropped 140 lbs.  in 2012 and have kept it off by counting calories via Lose it!.   Treating the depression that caused me to pack on the pounds made taking the weight off much easier.  I must be approaching an ideal weight as I'm still losing, but very very slowly.

When it comes to diet, I eat almost anything and everything.  I travel too much for work, and eat way too many meals in restaurants.  With very little control over the preparation of my food, I have found the key to my success seems to be portion control.  Running has given me the mental acuity to log the food in Lose It and live a calorically limited life. Running has also given me a caloric buffer.  Oh and I also gave up diet soda completely, and that was a heck of a monkey.  The only time I drink coke is with a finisher's medal around my neck from a half marathon or longer or with Jack Daniels while sitting in the first class cabin of American Airlines.
