I might be an outcast here with my response, but honestly it's the truth.
Being overweight for most of my life, my main motivation at the time was to lose weight so I could wear all the cute clothes my friends wore, but I could never fit into. This was mainly in college, I had super thin roommates who would could buy anything they wanted, and that became my main motivation, but I also never managed to lose more than 10lbs.
Last year when I was in grad school, I went to crossfit with one of my friends wanting to see what it was about and realized how completely out of shape I was. Yes, I could do the elliptical for an hour with resistance but it was nothing compared to the strength training they do. I also had my body fat percentage checked, it was so high it scared me. A few months later I went to the doc and my blood test came out so bad he contemplated putting me on medication (in my early 20s!), and a few months later I didn't qualify for health insurance through my dad's plan. I was legit scared that I was doing some major damage to my body.
Trying to lose weight for "clothes" never seemed to work for me, I was looking for quick fixes without making appropriate changes. While my motivation started from materialistic things it quickly turned into more of health kick and that's when I started to actually lose weight in a way I could sustain. This is the first time in my life that I have been in the 170s (since high school!) without gaining it back in a week or two.
Anyway, sorry that was much longer than expected, but this was a great question to ask
