i walk everyday for 30 min for 3 times (so that makes 90 min

I'd suggest getting a heart-rate monitor. Start tracking your exertion and calories burned during these walking sessions. Maybe your not burning as many calories over calories consumed, like you think you might be by walking. Gotta get that heart-rate up and bust a sweat. Losing weight takes effort.
The body is constructed with muscle memory. It starts to remember routine. What could be happening is you've been walking the same routine for years. Your body has adjusted. Its time to shake things up.

If you've already been walking like this for several years now, and only recently starting eating healthier, then I don't think you should really be counting it as exercise. Meaning, it's part of your daily routine, so you should adjust whatever you put for your type of lifestyle....for example moderately active or active. That's going to have an effect on how many calories you should be consuming each day which could mean you need more calories than 1400 (the more active you are, the more fuel you need).

In addition, your body burns calories even when sleeping. I believe around 500-600 calories per sleep period. But you don't count that as exercise. We walk around at work all day long or do light activity in the office or whatever. Your burning calories. But exercise is defined as the following....

"The Surgeon General of the United States defines exercise as physical activity that involves planned, structured, and repetitive bodily movements in order to improve or maintain physical fitness. As an element of health, exercise involves both strength training of the muscles and cardiovascular fitness, with stretching activities for flexibility. Most research on physical activity for fitness stresses the intensity and regularity of exercise as key elements. Typical exercise activities include fast walking, running, cycling, swimming, or aerobics classes. The latest Centers for Disease Control and Prevention report, in conjunction with the American Council on Sports Medicine, recommends that all adults perform 30 or more minutes a day of moderate-intensity activity for 5–7 days per week. The National Institutes of Health Consensus Development Conference Statement on Physical Activity and Cardiovascular Health identifies inactivity as a major public health problem in the United States. They have recommended exercise regimens 5–7 days a week for people who are already active, and such leisure activities as gardening, walking, using stairs instead of an elevator, cleaning house and recreational pursuits etc., for people who are largely sedentary."

Walking everyday, is good activity. Especially if your coming off an injury or haven't exercised in quite some time, working your way to a heavier workout. Maybe if your age or condition doesn't allow one to take on physical or laboring activity. But walking honestly, is bare minimum. Also, one would have to take diet, weight and health into this equation.

Looks like you have a pretty small to medium sized dog. Not sure what kinda pace your dog can keep up. But maybe try jogging alongside of them. Dogs, especially young ones, have more energy then they know what to do with. Try running with them. I'd be willing to bet you'd be challenged to keep up with them. I see people in my neighborhood running, biking and this one guy actually rides his motorcycle around the block with his dog running alongside. Its pretty comical, but hey you gotta do what you gotta do. The only thing worse than an unhealthy human, is an unhealthy, overweight dog.

I guess maybe walking isn't enough but I have to walk my dog so maybe besides walking every day, I should do something more. Honestly I don't really shed a drop of sweat when I walk my dog so I know walking is easy work out for me. Oh well.... gotta find another way!!

I wouldn't say that walking isn't enough. My main source of exercise is walking and boy am I doing well (my butt and hips are shaping up quite nicely). I also have dogs (all 20 pounds and below) and I'll tell you one thing about walking the dogs--the intensity just isn't there. A dog walk is 3.0 - 4.0 mph (depending upon the energy of your dog) and, depending upon your fitness level, you may be ready to up the intensity.

You could look up a couple of walking websites (www.thewalkingsite.com is one of them) to see what they suggest. I just know that walking can be a great workout. I'm working on getting up to a 5.0 mph speed and am thinking about walking in a 5K race.

A great way to gauge your intensity is to get a heart rate monitor (if you don't already have one). My hubby recently gave me a "running computer" HRM for my birthday. At first I was a little embarrassed by wearing a "running" computer HRM for my walking workouts :embarassed: , but it's absolutely awesome!!! I can track laps, speed, calories burned, etc.! :happy:

A final thought about walking being a workout and helping you to lose weight: look up pictures of racewalkers online--they look just as fit as marathoners!

Cheers to you, :drinker:
