A pound of body fat equates to approximately 3500 calories. So if you have a diet deficit of 500 calories (meaning that you burn 500 calories more than you eat each day) you would lose approximately one pound per week.

Your weight and the distance you walk determine the energy calories burned while walking. Walking speed matters less than distance and weight. A rule of thumb is 100 calories per mile are burned for a 180-pound person and 65 calories per mile for a 120-pound person.

A pound of fat equals 3500 calories. To lose 1 pound a week you will need to burn 3500 more calories than you eat that week. Losing one pound of fat a week is a sensible goal, but it requires burning 500 more calories per day than you eat.

The weight loss does not only depends on the workouts and walking, It is also affected by many other factors like, calories intake, calories burn etc,

30 lbs is nothing if you walk 10 km everyday, you can burn 300-400 calories which is not even enough for weight loss.

Loosing weight is not an easy task for our body. Loosing 30 lb is depend upon the how much effort you have been making to loose the weight. You are doing very intense workout then you will easily lose your weight in very less time.
