Help me lose weight!

Hey wow, you are motivated, that is awesome.

Questions for you: Do you wear a heart rate monitor? Does your trainer switch up your workout at all or is it always the same? Are you overweight and trying to lose or are you average weight trying to tone?

These can help us figure out some ways to help.

Sounds like you're on the right track to me. Try taking measurements instead of weighing yourself. Sometimes weight is a tricky thing because you could be losing fat, and gaining muscle.

I found that when I limited my calorie intake that rigidly, I either gained weight or stayed the same. My nutritionist said I had put my body into starvation mode and that I wouldn't see any weight loss if I continued. Sure enough, I added about 250 calories to my diet to make about 1900 on the weekdays and 2400 on the weekends (my long run is on Saturday - sometimes up to 3 hours) and I saw drastic improvement. Think about it, if you're limited to 1500 calories, and you run for an hour, you burn approximately 700 calories, you're asking your body to live on 800 calories a day. You've put yourself into starvation mode!

WOW! Thanks for all of the great input!

I am not wearing a heart monitor and use the one that is on the treadmill which I know isn't completely accurate. Would that be advisable?

My trainer changes my weight training regimine every 2 weeks. I pretty much do the same cardio (30 minutes of the elliptical cycle and on the treadmill - 5 min warm-up, 10 minute run, 10 minute intervals, 5 min cool-down) throughout the week.

I'm trying to lose weight and tone. The interesting thing is that I did have a fitness evaluation done and though my BMI categorizes me as "overweight" at 27, my body fat content is 24% which is "healthy" and "fit" for women (that's what the evaluation itself said). My body style is "athletic" and its really impossible for me to be super skinny.

I was thinking the problem could be my calorie intake so thanks for pointing that out. I was anorexic for 4 years (10 years ago) and so I've always had a love/hate relationship with food. I was in the habit of using a food journal before and maybe I should do that again. Any suggestions on how many calories I should be taking on? I've gone to a couple of websites and asked people, but I get different answers. Any more suggestions would be great!

A few things.

1.) I would definitely get a heart rate monitor. You're body may be getting used to your cardio routine and this way you can see if you're actually getting your heart rate up or not. That being said, maybe try doing 30 mins on the bike, or 15 mins rowing and 15 mins on stair stepper... give your muscles a little variety and see if that helps.

2.) Check out the fit calculator to see some calorie options. Like leeegirl said about starvation mode, you may actually have not been consuming enough calories to burn fat and build muscle.

3.) BMI's are funny like that -- They are just loose guidelines for people looking to see where they sit, but they are not the end all be all to your body. A body fat evaluation is much more thorough since it differentiates between the weight of muscle mass and that of the fat mass while BMIs just lump all masses into one figure.
