Hi there!
I'd like some stats before handing out more detailed calorie advice.. how tall you are, how much you weigh at the moment...
If you're supposed to be eating 2,000 calories, but then only eating 1,000 and burning off 500 from exercise alone then it's no wonder you aren't losing weight! Your body is holding onto everything it can get for dear life. Most people need around about at least 1,200 calories to be healthy. And that's just for the smallest of us.
Burning fat efficiently has got to start with eating
enough. Starving yourself is harming your health.
You can do this, you can lose weight & be healthy.
Best of success!
