Runners ONLY....

When I started out I couldn't even run for a minute on the treamill before I wanted to take a walk break. Now, I can run for 30+ min and do so 3-4 times a week and I have registered for a few races this year. I lost my first 15lbs by circuit training and logging my food. I got into running as my main form of exercise I dropped another 15lbs gradually. I'm hoping to lose another 5-10lb by tightening up my diet, running longer distances and adding more strength training. Good luck!

Must agree with the lady above, I do not lose weight running. Been vigorously training for a half marathon and only lost maybe 3 pounds over 12 weeks, and it fluctuates a ton because I retain loads of water after a long run.

Running is WONDERFUL and I would never kick it out of a healthy lifestyle but distance running probably is not going to inspire tons of weight loss in someone who is already about a healthy weight. Keep up the running but add in lots of strength training!

I've lost 55 pounds from running only and eating better.

I gained 12 pounds when I was training for a marathon. Running long distances makes me HANGRY. I love running. (Or slogging in my case... slow jogging). But I'm cutting back on the distance for a little while so I can lose weight. I'm doing more weight lifting and yoga. I still run probably 14-20 miles per week, but that's way less than the 35+ miles I was doing each week during training. After I've lost weight and feel like I'm capable of maintaining it while training, I'll do another marathon. Until then I'll stick with 5Ks and fun runs.

Initially, 30 lbs but since I've started training for races nothing really. I've found that for me personally, it only helps in weight loss if its a light short run, say 30 mins combined with a light training plan like Jillian Michaels Ripped in 30. Its great for maintaining though.

Good luck!

Running is my main exercise, but I also strength train at least 3 times per week. Anywho...I've lost almost 10 pounds in just under a month.

Id say running keeps the weight off, burns so many calories I can eat well that day, and I would venture to say slims the legs and torso, thats from my experience not a science lab on rats ( for the benefit of the miserable trolls on these forums)

I lost about 33 lbs. since beginning running which is before MFP days -- then I gained some back most likely due to adding in some strength training following StrongLifts 4x4 -- at present I am only doing running again following a 1/2 marathon training program and have again started slowly losing a few pounds.

It depends. Weight loss is cals in vs cals out. Any workout that burns calories has to be compared with what your body takes in vs what you expend in your daily activities including any exercise.

Running can be tricky because if you get into "races" and running competitively you may not be able to lose due to having to take in enough to keep your body healthy and ready to train. if you are running for fun then you will lose whatever you are in the deficit of.
if you have a calorie deficit of 500 each day (eat 1500 and burn 2000) then you'll lose a pound a week. I did find running (as it pertains to me and many) to be the highest calorie burning activity in the shortest amount of time though.

That being said when i started running more competitively (for PRs <personal records> not like winning for money) and around race time i am in full maintenance mode as you need to fuel your body to perform the best it can under extreme circumstances and some of my friends who have trained for marathons have gained due to eating more to fuel themselves. It all comes down to cals IMHO.

all that being said i love running and find it to be the best calorie burner for me :-) I hope to keep running for many many years and hope to do my first marathon this fall after doing another Tough Mudder in June.

Running is a great form of exercise and I think you can lose weight by changing workout intensity by adding interval training into your regimine. But I would agree with the others that it's really best to incorporate strength training into your program which gets increasingly important as we age. The other cautionary advice is that the accumulated pounding from running over time increases the risk of injury, especially if that's all you do.

So keep on truckin' but also spend some time on building overall body strength...
