Every single time someone says "I eat the same as them" it's been shown to be self-reported, and therefore not verifiable in the least, including this current study. There's a show called "Secret Eaters", you should really check it out. People lie, to themselves included, about how much they eat and how much they exercise. Add to this a 4ft woman will not have the same BMR as a 6ft man, and there's no reason to go searching for some external influence. There are psychological issues, to be sure, but except for rare exceptions (like Crohn's and extreme outliers, ie, not common) people of the same height and weight are within 200-300Kcal of each other BMR wise (source: http://examine.com/faq/does-metabolism-vary-between-two-people/ http://examine.com/faq/does-metabolism-vary-between-two-peop...)
