No, brisk walking for 45 mins a day would make you more fit, but it is unlikely to do much to help you lose belly fat.  Belly fat and love handles that develop during middle age are the first signs of metabolic syndrome.  This kind of fat resists reduction by even a combination of exercise and diet.  This is because as we age, the level of testosterone (in men), estrogen (in women), and human growth hormone (in both men and women) progressively decline.  These hormones are essential for maintaining lean muscle mass and strong bones.  Without adequate levels of these hormones, muscle cells would shrink in size, and fat cells would increase in size.  Weight lifting can help increase the production of testosterone and human growth hormone levels to help improve lean muscle mass.  But after a certain age, even weight lifting can only go so far.  That is why even professional body builders will start to lose their edge after the age of about 45, no matter how hard they train.

Having said this, I think you can still reduce abdominal fat to a greater or lesser extent using a combination of low-glycemic diet (even if you are not a diabetic), aerobic exercise of adequate intensity (walk or run until you sweat), and weight lifting geared towards building muscle mass.  And of course, there is an easy way.  Hormone replacement therapy and the use of diet drugs can easily help you lose belly fat, but their use need to be supervised by a medical doctor.  Please visit the Weight Loss Health Tips page on my website http://www.best4health.net for more information.

Brisk walking will help, but it's only one part of the things that you need to be doing.  The others are: reduced calorie diet, whole body functional strength training to build muscle, and ab/core training.

As far as your walking goes, you should do intervals.  If you have hills available to walk in, that makes it easy to do. In an interval training workout, you alternate between periods of hard exercise and easy exercise. For example, after your warm-up, you'll pick up the pace to high intensity for 30-60 seconds and then bring the intensity down to a cool-down pace for 1-2 minutes. You'll repeat that cycle 6-10 times total for a massive fat burning and metabolism boosting effect. This is a real quick workout that takes only 20-30 minutes. Researchers believe that interval training triggers the body to release adrenaline, a hormone that tells the body to burn stored fat — which is often found in the stomach area.

i have a belly fat not so big but something i'd love to get rid of... i "earned" it due to long hours at my computer and less movement. so i started brisk walks after my work. i'll get down few stations before my apartment and then walk.. so  from my own experience i didn't really lose belly fat but i noticed that it helps me control my weight... so the verdict is... it needs more exercises than brisk walks to lose belly fat... ab exercises, jogging.

I might add that one of the most important things sisto modify your diet to lose weight. Eat more broccoli, cabbage and cauliflower with healthy fats like virgin organic coconut oil and extra virgin olive oil along with protein.
