Am I going about this in the right way?

I am trying to loose some weight. I am female, 5'6", and I weigh 190. I am trying to loose 20 more pounds. I am doing this for myself and for my Fiance. This is what I have been doing for the past week...Run a mile every morning, then 25-30 min on the elyptical, then about an hour of yoga and/or Zumba ...all in one day. I have been eating about 1000 calories a day. I would eat more if I were hungry, im simply not hungry... I have also been smoking (hookah) to curve some midnight snacking moods. haha. Am I doing this correctly? My good friend told me that I need to be eating more. but idk, i feel that would just set me back in trying to loose weight.

I am doing this mainly for myself...however my fiance has been in bootcamp for about three months now and he has told me that he has lost about 20 pounds (he was a bit of a chubster when he left..but he was perfect for me...) and so that is just making me want to loose the excess weight I have so I can be healthier and try to keep him attracted..or more attracted to me.

I am not worried about him going after other women, I know he loves me and no one would change that. no matter how sexy. he is very loyal as am I. : ) please help by letting me know what you think about the plan I set.

thank you
