I urge you to listen to what
oneofthose is saying because it's exactly right.
What you need to also consider is that by getting rid of food in your stomach, or skipping meals, it will slow down your metabolism which actually makes it a hell of a lot easier to gain weight, especially if you're prone to it from the beginning.
I've been through all this, hated the way I looked and thought I was too fat and started to starve myself and throw up when I binged. The first time was easier because starving myself didn't seem to feel as painful (you know...the hunger pains) I had a lot of trouble purging though (lets just say...it's not my strong point...how morbid..lol).
the first time, my mum almost sent me to a clinic, but I started to eat again for fear of that. The second time was worse, I starved and overexercised. I managed to hide it from everyone until it became really bad, but as my relationship of 4 years ended...I started to eat again. The third time was probably the most weight I've lost. I was in a bad relationship and went back to overexercising and starving. I even went as far as to keep a log of every single thing I ate and it's calorie content. I was surviving on under 500 calories and over 3 hours of exercise a day.
Each time I did this it was not pretty. I looked gaunt, sick, ugly, and extremely tired. I also gained weight extremely quickly once I tried to eat normally...or even after starving myself for a little while and then eating again...your body goes into starvation mode and all you'll be doing is storing fat every time you eat.
I'm not going to lie though....if you starve...you will loose weight...but it will be muscle weight that goes first. I found this out the hard way...as my 'jiggly bits' became a whole lot more jiggly and wouldn't 'un-jiggle' themselves no matter how much exercise I did.
If you want to loose weight....go Vegetarian or Vegan! just being on that diet alone will make you loose weight (without exercise...100% positive of this considering i've been lazy for a while now...lol)
It might seem easier to just purge....but I guarantee you it will only make things harder. Actually my sister is a perfect example as her problem was more extreme than mine. She was bulimic and actually managed to get down to an extremely low weight...but looked incredibly sick. She now has a lot of stomach problems and managed to gain quite a bit more weight when she started eating healthier again. It's taken her a long time to work off the weight...she's still slogging it out at the gym and has recently gone Vegan as she's seen how effortless it is to lose weight this way and still be healthy (and eat a lot!).
oh crap...I've written a small novel as usual...lol...it's just a topic that is close to my heart and something I've found an alternate solution to that keeps me healthy and conscious of what I'm putting into my body.
