TweetIf my math is right, you are just over 200 lbs, right? There are some general rules of thumb out there but they differe for everone. Fore example is goes something like this:
Weight (lbs) x 10 to lose weight
Weight x 12 to maintain
Weight x 15 to gain weight
So, I'm about 250 so to lose I would take in 2,500 calls, to maintain I would take in 3,000 and to gain I would take in 3,750. Of course, these are very rough numbers and not exact for everyone. I had my basal metabolic rate calculated by a RD once and she said I was at 2,800. So, that ment my body burned 2,800 cals just doing nothing. I was more active then but I'm bigger now so I really don't know where my BMR is now. If your BF is 18.5% is a pretty good assumption that you have a normal metabolism. It's not too slow and it's not fast so this formula may work for you. Try eating 2,000 cals a day and see if you drop weight. If you lose more than 2 lbs a week, or one kg a week, then raise the cals. If you lose too fast you will lose muscle and that won't help your overall BF composition.
