If a person is 17 and weighs 200 lbs with little activity and cuts down to 500 calories per day how much will they lose in a month?

This would be totally dependant upon your metabolism, body shape, gender, and general mentality.

I would really not suggest this change in diet, mainly due to the fact that your body will go into panic mode and try to cling on to every last ounce of fat that you give it, meaning that you will not infact lose much weight, and any you do lose, will most probably return immediately you take your diet back up to the normal calorie intact of between 1500-2000 if you are a woman, and 2000-2500 if you are a man.

Please stay safe & sensible with your diet, and try to get some help to lose weight safely from your doctor or local diet club. They will probably sugest, increasing exercise, reducing sugars and fats and increasing your intake of protein, fruits and vegetables!

Hope this helps!
