[O]nly 3.5 percent of Americans between the ages of 18 and 59 get 150 minutes a week of moderate activity, yet about 1/3 of American adults have a BMI of < 25. Even if you assume that all of that 3.5 percent is “normal weight” and “underweight” people [protip: don’t!] the vast majority of thin people do not get the recommended minimum amount of exercise–let alone hardcore-fitness-nut amounts of exercise.
I’ve been told all my life that I’m fat because I don’t exercise “enough” But if only 3.5% of American adults exercise “enough” to maintain health, maybe we fatties are exercising too much? Or, y’know, maybe setpoint is real and weight is largely inherited?
