Walking makes me perspire. I know before that I lost weight when I was trying to make 10,000 steps a day. On my way to work, I can have 5000 steps already and going home from work, I have 5000 steps again. I lost weight but during that time, I was trying to drink 8 glasses of water a day that is why I think drinking water has something to do with losing weight also. If you cannot have or do some exercise due to your busy time, you can do brisk walking. If you cannot do it, just walk on your way to wherever you go. 10000 steps a day will help you lose an inch of your belly fats. It will make you lose some fats in belly, legs and back. Also, it can promote good heart rate just like jogging but on a slower slide. If you cannot afford to take a diet and exercise, you should walk.
