Should I lessen my calorie allowance as I lose weight?

As I lose pounds, should I recalculate how many calories I can have? I'd assume I'd need to eat less at 186 lbs than I would at 189. Or should I just stick to the calorie amount I started at until I hit my goal weight?

Yes, you have to adjust it down, but it's not much.  I would recalculate after losing about 10 pounds or so. 

Actually, if you enter your info on here, it will adjust it for you every time you input your weight. 

Cool! I did not know it did that! Thanks :)

Your energy needs will not change much if you're only 10lbs lighter.  When I lost 50+ lbs I think my calorie intake reduced by 100 from start to finish.
