Walking does help with weight loss. According to the Mayo Clinic, walking generally does not result in significant weight loss on its own and should be combined with a reduction in calories to be most effective.
To create more of a calorie burn while walking, consider increasing speed or intensity. Recent study results published in Health show that women who increase their speed in three out of five walks per week lost six times the abdominal fat of women who walked at a slower pace.
WebMD suggests that walkers monitor their heart rates in order to target a good speed for weight loss. To maximize calorie burn exercise within the aerobic zone, which falls between 70 and 75 percent of a person's maximum heart rate.
