If you're very obese, walking can burn a fair amount of calories. If you're closer to a healthy weight, it won't burn many at all - I burn about 200 calories walking at a steady brisk pace for an hour - probably more like 180, to be honest.
Weight loss is about calories - you have to burn more than you consume, period.
Walking, like anything else, can vary in intensity. I was in a similar place as OP (5'4 and 160 pounds) and dropped to 115 over about 7 months. I cut out most processed foods and other junk food, but did not count calories or cut out meals or snacks, and I walked for about an hour every day. i've kept the weight off for about 18 months and I eat a lot (2000+ calories/day), so I really don't think I am burning <200 calories per walk. Maybe PP weighs 90 pounds or something.
I do find it easier to stay in a consistent fat burning zone for most of an hour by walking on the treadmill. I usually maintain a pace of 4.3 mph and an incline of 10 for about 4 miles with a brief warm up and cool down, and usually one or two laps of slow jogging (like 6.5 or 7 mph). I had to work up to this a little bit, but even when I was starting out, I didn't have trouble with a 4mph pace and a 5 or 6 incline. I am often drenched in sweat when I'm done. I have not had any joint injuries though - it's possible that this would be too much with a bad knee.
I am also older (late 40s), so my kids and their tempting snacks were gone before I really attempted to do something about my weight. That definitely made it easier for me to clean up my diet.
I'm 130lbs at 5'3". Tracking walking with my Garmin, I burn about 55 calories/mile. 200 calories in an hour at a fast pace with some stairs is a good estimate, if a little high.
I lost about 60lbs and have kept it off for almost 9 years. Walking is a good start, but higher intensity exercise was critical to getting my heart rate up to get not only a higher calorie burn with exercise, but also a surge in my overall metabolism.
Walking is great for the reasons mentioned above, but I think for most people it just isn't enough to burn many calories.
btw, walking uphill on the treadmill at 4.3mph, with a 10 incline, for 4 miles is awesome!! Bravo--that's badass!
OP, incline/uphill walking is great and will burn more calories. If you do it on a treadmill, please be sure to not hold on to the machine. I find uphill to be ok on my knees, but holding on will torture your back (with zero benefit). Start slow and steady with what you can do with good form, and gradually increase the intensity.
