Duh!!!! Have you ever tried to keep up with a tall person on a walk? You are taking 1.5 to 2 steps for each one they take! This one of those things you intuitively know but science has to prove it to you! 🙂 Now if you are short and have a higher BMI you will be on fire!!!
ScienceDaily (2010-11-14) — Why do tall people burn less energy per kilogram when walking than shorter ones do, and how much energy does walking require? These are basic questions that doctors, trainers, fitness buffs and weight-watchers would all like to have answered, and now researchers from Texas have derived a fundamental equation to calculate how much energy walkers use, based simply on height and weight, which has direct applications across all walks of life.
