For motivation - one thing that may help is this.

If you're slender to normal weight nowadays (and by normal, I mean normal as of maybe 50 years ago, and not the "average" weight of people nowadays) - you are honestly one of a rare few. The vast majority of people are overweight or obese.

Simply being slender and healthy looking gives you a huge boost. It's like a superpower. People respect and trust you more. They will think you have it together.

Despite the fat-acceptance propaganda, this is true.
