At that height and weight, it seems you're "overweight", but nowhere near "obese". As has been pointed out, 25 pounds in that time is a highly aggressive goal for anyone. It would help if you weighed 250 now. If you've had thyroid problems in the past and always struggled with your weight, it would be a herculian effort to attain that goal.
You may have to consider the possibility that losing those 25 is going to take you a year, regardless of any extra difficulty with trying to do marathon training at the same time. Three months is just way too soon.
I'm not saying "don't try". But ... you have an extremely aggressive and unrealistic goal. Don't beat yourself up if it doesn't happen.

I am 45 years old. 5'4" and 157 pounds. I have been running for several years and as of last fall, I had ran 9 half marathons in 24 months. I have followed several training programs for both distance and speed training depending on which race I am currently training for, usually either a quick 10km run or a half marathon. I also have an under active thyroid so struggle with any weight loss. I have lots of muscle mass in my legs and tend to carry my weight in the front. I did allow myself to go over my calories on the day of my 19km run by at least 200. Not sure if this is enough extra but I do suppliment with an extra protein shake after most runs that are over 10km in distance. I can adjust my weight loss goal somewhat, but I am still very determined to lose a reasonable amount of weight before my race. Not only for my mental running stamina, but also for my knees! Thanks for all the helpful responses so far!
Hate to tell you but not only is it hard to lose weight in marathon training, often times people gain. I went through it last year and there were days when I was ready to eat the sofa - very strong physical hunger. I was very lucky that I was able to maintain my weight but know that with intense training you need to fuel for success.
Just wondering - what's your running background? I'd like to be sure that we are encouraging good habits both in training and in diet.

Why do you think you need to lose 25 pounds before your marathon? What is your running experience? Have you been losing weight already? How much and over what time frame?
I agree with the concerns in this thread that 25lbs is an (overly?) ambitious goal in this timeframe.
And training for a marathon places a lot of demands on your body, and requires a lot of resources - both in terms of energy, and free protein to keep up with all the little repair jobs. Running a large calorie deficit to lose weight that fast is likely to compromise your training. I'd recommend focussing on one goal (weight loss or training) rathe rthan both simultaneously.
But in answer to your actual question, Spark will take care of all the math for you. Work out how many calories you are burning through exercise in a typical week. Then update your Spark Exercise Goals (accessible from the LH side of the Start page) to reflect that figure, and Spark will recommend a intake consistent with your needs. My advice would tod also update your target rate of weight loss to something more consistent with your training goals (eg. 0.5 lbs per week).
I agree with both Jen and Heather. 25 pounds in 3 months is a huge aggressive weight loss goal for anyone, and if you're capable of running a marathon, probably far too fast for your body.
And endurance running and weight loss just don't mix well. It is best to focus on one or the other.

It can be very difficult to lose weight while training for a marathon, especially at the rate you're hoping for. The problem is that you need to eat enough to fuel your training needs, but if you don't cut calories enough, you won't lose weight. My advice would be to focus on maintaining your weight while training, and then once the race is over you can go back into weight loss mode again.
Hope that helps,

Update your fitness goals here on Sparkpeople to include the approximate calorie burn you're spending each week, and make sure you have a reasonable goal set up. You can safely attempt to lose about 3% of your remaining weight loss goal weekly. You don't have your weight listed, so 25 lbs in 3 months may be too aggressive for you. That's 1.5-2 lbs per week, doable if you're over 200 lbs, but very difficult if you're less than that.
What's your current weight/height?
That will ensure you get the fuel you need to power your workouts. Marathoners should also not avoid carbs; carbs are the body's preferred fuels for endurance events like that.

I am currently training for my first marathon and trying to lose about 25 pounds before my race in 3 months. I worry that my allowed calories for the day is not enough for all the running I am doing (approximately 30 miles a week). How do I know if I am getting enough nutrition?
