I know where you're coming from. 18 months ago I weighed the same as you, and up until then was consistently unsuccessful in losing weight and hit rock-bottom emotionally and physically before I somehow summoned the strength to change.
To answer your question (and a few unspoken ones!
"Where do I start?":
Start at your mouth.
* Eat plain healthy foods that don't have added fat, sugar or salt (that's pretty much anything that looks like it came off a tree or grew out of the ground or off a fish or skinny cow).
* Eat less than you need to eat to maintain your weight.
* Do some exercise. Anything, like walking around the block or climbing up and down stairs.
"When do I start?":
* Don't start "Tomorrow". Tomorrow never comes.
* Don't wait until you feel "inspired" or "confident" or when the planets align and it "feels right".
* Just start right now and don't stop.
"Who is going to help me?"
No one can can lose weight for you. You're responsible for the decisions you take on what you eat and when and how you exercise. Any advice, empathy and encouragement you get from here and other sources around you are only effective if you are making positive decisions at the same time.
"Where can I find out what the best way to lose weight is?"
Many years worth of medical studies and experiments have produced a clear set of guidelines:
* A person has to eat less food energy than he or she needs to maintain a stable weight. That's the only way to reliably and consistently "burn fat".
* Exercise - it assists weight-loss by maintaining muscle tone and bulk - weight-loss uses muscle tissue, exercise rebuilds muscle tissue, muscle usage expends energy and promotes weight-loss.
* Maintain nutritional levels when eating less food - by eating food with a higher nutritional value than before.
* It appears that the aim of many of the PCOS-related weight-loss strategies is to address the insulin resistance issue - a low-GI diet plus regular exercise seems to be the generally accepted method. I'm sure you doctor would have provided you with the info on this.
All the hundreds of fancy diets and techniques and systems are based around those points above. They are varied to suite the different motivational, nutritional and lifestyle needs of people. Some will have slightly different results, but in the long run the results are the same - a healthy, happy person.
"Where do I find more information?"
Here in the Weightloss web site:http://www.weightloss.com.au/diy-weight ... ogram.html
The very first sentence on that page reads,
"Most of us want to lose weight but many of us don't know where to start."
It has a simple plan that can be tailored to your own needs. Having a goal-oriented plan is important - without one all you'll do is flounder around getting nowhere.
There are plenty of useful articles here as well. For example, one on "eating behaviour":http://www.weightloss.com.au/articles/w ... viour.html
That's about all I can think of for the moment. Hopefully it's given you something to go on.
