Ancient Nubia occupied the territory beyond, or upriver, the first cataract while Ancient Egypt occupied the lands below, or downriver, of the first cataract. Historians have come to divide Nubia itself into sub regions with Lower Nubia comprising the lands between the first and second cataract and Upper Nubia being the regions beyond the second cataract.
How You Burn Calories. Your weight x distance = energy used walking. Time does not matter as much as distance. If you speed up to walking a mile in 13 minutes or less, you will be burning more calories per mile. But for most beginning walkers, it is best to increase the distance before working on speed. A simple rule of thumb is 100 calories per mile for a 180 pound person.
1 Mile walked = 100 calories burned. 1 Pound = 3500 calories. 2 Pound weight loss per week = 7000 cal, or a 500 cal deficit per day. 1 Pound weight loss per week just by walking = 5 extra miles walked per day-or 7,500 extra steps (in addition to the distance that you are currently covering while maintaining weight). Pound weight loss per week with diet changes and walking combined = 2.5 extra miles walked per day (3750 extra steps), and 250 calories less consumed per day, for a total daily caloric deficit of 500 calories.
