Pontzer's findings have huge implications for our attitudes to exercise, diet and public health' Mark Webster, Sunday Times A myth-busting tour of the body's hidden foundations from a pioneering evolutionary biologist 'Public health strategies stubbornly cling to the simplistic armchair engineer's view of metabolism, hurting efforts to combat obesity, diabetes, heart disease, cancer, and the other diseases that are most likely to kill us' Herman Pontzer's ground-breaking research has revealed how, contrary to received wisdom, exercise does not increase our metabolism.
