I would love to read about that one. I personally think that the reason one becomes fat could be many things. It's not always like the common stereotype that people said. For example, I am someone who eat less but having a slow metabolism is a problem itself.
Friends asked me to eat more (since I have always use fitnesspal)but the more I eat even, just the baseline for my body to function, I would gain weight quite easily. I also have stress and sleep problem which all of my doctors told me it contributes to my weight gain. And no, they are not stupid(I read the comment earlier). Like me, I think too much and that leads to stress, and for me, stress is a factor that leads me to weight gain. And well, looking forward to what you have to say about weight and all that.
