I never cared about weight while I was in school. Anyway, no need to mention a detailed life story here. In short I gained weight- got knee problems wanted to lose weight. And since I was over 30yrs, it wasn't easy to get off the weight quickly as I did in my 20s. I didn't want to invest in Gym memberships or personal trainers, So I Googled all about it, here's what I did to reach my optimal weight.
