I am fat because I was rejected when I had six pack and vains in every place possible (lean as a mother fucker).
I was called ugly by women.
Later I thought ok, maybe it was women at my area, and lost weight again (I didn't go to ripped level this time, just regular weight)
Guess what, they were rude as fuck as before.
Now I am around 20kg overweight because I give no fucks anymore. It's actually hard to lose weight and hard to gain weight. The weight mostly tries to stay the same.
I've done water fasts and lost around 10kg in a month and also done binges and gained 10kg/ month
Both are something you have to try to gain.
