advice please
 

i am rite on the border of 1800 and 1600 cals should i go with the higher or lower????

On the border according to what? There are a lot of online calculators to help you figure out how many calories you should have. Maybe try a few of them and pick something in the middle?

I use fitday. A couple others I have heard of are livestrong and loseit. Do a google search.

I aim to eat between 1600 and 1800 every day. I don't aim for 1 number, or the other, I just aim to get between the 2, some days it's 1610, and some days it's 1780. It seems to be working for me, for now at least.

I agree about the range. I lost most of my weight in '09 then gained some back with injury and stress. I'm back to losing and heading to a new final goal. The first time, I really stayed in a tight range of 1200 to 1300. I had fixed meals, steady routine days of work and life, and massive commitment. Now, I'm more 1300-1450. I also know my exercise burning rates are a bit higher with heavier weights and lots of extra walking. I may have to reduce the calories down to 1200-1300 soon if I see a plateau forming. So far, I'm on track: 1 pound or so a week and 12 weeks to go.
