Once I figured out what was wrong with me, fixed my diet and got in shape, the way people treated me in general shifted dramatically towards positive. Rather than starting from a unreceptive low with everyone new, I started with a positive welcoming reception. People would just defacto trust me and assign me positive traits just for being good looking.
It's mind blowing to me how there is so much focus on whatever -ism, but no one talks about "looksism". Regardless of your gender or race, if you look good, people will default treat you well. If you look bad, every encounter is an uphill battle.
