If you've been following a 1,300-calorie-per-day diet but have lost no weight, it's possible that you're actually eating much more than you expected. This is very common, because if you're not accurately weighing or logging your food, you might underestimate what you're consuming.

He explained that "muscle is more dense than fat, so an identical volume of it will weigh more than fat." Exercise physiologist Krissi Williford, MS, CPT, of Xcite Fitness, agreed and said even though your muscle mass weighs more than your fat, "it takes up less space, which is why you look leaner and more toned."

Most rough estimates revolve around 100 calories burned per mile for a 180-pound person. How many miles are 10,000 steps? On average, 10,000 steps are going to come out to be roughly 5 miles.
