Thank you all for your replies! It means a lot to me that you took your time to write.

Ellemm - I think you're right, I am focusing way too much on dieting rather that just have a healthy lifestyle, but I still look chubby, and I have a lot of fat around my waist and exercising does not help I definitely don't want to end up being one of those girls obsessed about the way they look, so I'm working on boosting my self-esteem.

Anne - Thank you for sharing the article, seems really interesting!

orchid - well, I'm drinking a bit more milk now, but it's skim milk and I only drink it in the morning. I try to exercise as often as I can, but sometimes I just don't feel motivated enough.

I'll keep you updated on how this is going, and thank you all again for your thoughtful words.
