This month, researchers at the Scripps Institute in Florida found that mice injected with a protein called REV-ERB underwent physiological changes usually associated with exercise, including increased metabolic rates and weight loss. The scientists suggested that we are therefore closer than ever before to creating a pill that provides all the benefits of exercise. Many support the time-saving benefits of such a pill, as well as the obvious health advantages, but many have concerns about its effect on fitness and sports industries, as well as its effect on one’s discipline and work habits.
