a little over two pounds a week is a pretty healthy aim...

 
"How can I Lose 1 pound of body weight per week?"

 
One pound of body fat is equal to about 3500 calories. So to lose 1 pound of weight per week, you need to eat 500 calories/day LESS than you burn.

But it's not a good idea to lose weight simply by cutting calories. As well as decreasing calories you should increase your daily physical exercise. This helps to burn calories and build more lean tissue which in turn burns more calories.

 
You would have to eat 1000 calories LESS per day then you burn. You might tend to get a little hungry, so stock up on vegetables and drink lots of water.
