We’ve discussed this on one of the “fat” threads that brian was posting on.
The note that skinny people are not always healthy jibes with what I’ve witnessed among our friends, relatives, and acquaintances.
Many skinny people, especially women, manage to stay thin by cutting out vital foods (nutrients), smoking lots of cigarettes, taking “speedy” diet pills and supplements, drinking coffee non-stop, etc. Very few people, especially middle-aged women with children, can live a healthy lifestyle and still come out looking like Angelina Jolie (brian’s stated model of what women should look like, though I think she looks unhealthy).
Even the men we know who look “fit” have very unhealthy diets and lifestyles; they live on protein powders and weird supplements, don’t eat fruits or vegetables, etc. Then, they spend countless hours bulking up at the gym, staring at themselves in the mirror, and end up with all kinds of joint, muscle, or other tissue damage. Not sure why anyone would think that’s “healthy.”
