Running for Weigh Loss?

That's great and you will normally see some results fairly fast. Of course running is only part of the equation. You need a calorie deficit. so running can burn quite a bit of calories helping you have that deficit. Realistically it is safe to target 1-2 pounds a week. 40-50 minutes 4 times a week is great. I would get a heart rate monitor and keep inside your targeted heart rate. It can motivate to move faster and sometimes tells when to slow down too. I would also not do only running. Strength training is important too. Muscle burns more calories than fat so adding muscle will naturally make you burn more calories.

Changes in your body... Almost immediate sense of feeling better attitude. 1 week to feel more energy and drive, 2 weeks to feel smaller and drop some pounds. But this may be different for everyone and the key is to keep it up. It takes several weeks to build a habit, but in time it becomes a way of life rather than a diet or exercise plan. After a month or tow you do it just because it is what you do and you feel good doing it. Then the pounds are not even in the front of your mind anymore. It may take 6 months or even a year to reach the final goal, but as long as you are improving and ultimately start to enjoy your running, then that is most important thing.

I'm only down 13lbs but I'm down over 24 inches in just 3 weeks! Running has made all the difference for me. When I first started with c25k a few weeks ago I was barely able to clear 1 mile at the end of the 30 minute workout. Now I do the 30 minutes workout, and then speed walk/jog for another 30 minutes almost daily. I can now do about 6 miles everyday in an hour. I really recommend speed walking for an additional 30 minutes after your regular run. It's made all the difference in building up my endurance for longer/farther runs.

As for noticing a difference in my body.. Honestly? One week after I started adding the 30 minutes of speed walking/jogging to the end of my runs I noticed a big difference in the firmness of my legs, a loss of some of my cellulite on the back of my thighs, and my energy levels were through the roof.

Wow that's great! I've been procrastinating starting my C25K app for a while, but you just might have motivated me to get started sooner than later!

I have lost around 5kg since I started running in May. It's fairly consistent with the goal my calories are set for me to lose at. So, running has helped there in combination with eating appropriately. I think it has helped the weight to finally start coming off the mid section more than other exercises, like cycling, where your stomach is tucked away.
Definitely a combo of running, lifting heavy weights, trying to get my steps up on the fitbit on non-run days, getting the right amount of calories and not abusing the burn from runs as a free for all, has helped me lose consistently and things to start looking how I want them to.
