I exercise and try to avoid trans fat and keep my saturated fat intake within sight of the recommended daily allowances. Sometimes I pig out and eat a pizza or something that I don't usually eat and it's OK because I quickly burn off excess calories. However, if I stop exercising for a week, then I start to feel bad, and I might feel bloated or even get headaches, and this prompts me to start back up again. I know my health would become poor if I stopped exercising altogether.
It hasn't helped my social skills. If anything, it's made them worse and it has taken me a long time to get accustomed to the difference in how I look. I get a lot of stares and I'm not sure how to interpret this and it makes me feel weird even though it's probably a good thing. I don't care. I will still keep doing it.
But for some, it's possible that a difficulty with reading people might originate from receiving mostly negative cues and having to tune them out to stay sane, rather than an intrinsic inability to read people. People may treat you badly if you can't read their cues. Then again, you may be bad at reading cues if there's nothing good or pleasurable to interpret. In that case, if exercise makes you look better, then you may start getting positive cues and your social skills may improve when it becomes pleasurable to read other peoples' nonverbal signals.
