Many say that if you aint a seasoned lifter (newbie) doing a (40-30-30) program can help you lose fat and gain muscle at the same time, yet as you become more and more experienced this becomes harder to do.

By cutting they usually cut back the carbs to no higher than about 50. A key to this idea is no carbs after 6pm or sometime early.

Follow Body-For-Life if you are still somewhat new to the scene. It worked for me. The book can be found at amazon.com.
Good beginner info.

Oh yeah....to bulk, eat everything in site.
You will bloat up, but you will be strong.
Then it is usually followed by a cutting cycle to trim down the extra fat gained during the bulking cycle.
If I were you I would cut first (leaner you are=bigger you look!).

Generally, people using AS especially if they're bulking are eating as much as possible so the steroids can convert food etc to muscle. If you were on roids you would probably not restrict your diet that much unless you were in a cutting cycle.

Personally, I've done the 12 week program and had good results. I still eat 6 meals a day on most days. It's just a good habit to get into. Even though I'm bulking right now, so the meals are not all small.

Assuming you are a man, 19% body fat is a little high depending on your age. If I were you I would try to cut up, by doing resistance training and intense cardio 4 - 5 days per week. It's a personal choice for you to decide when to start bulking.

When you've reach you've reach your body fat % goal, and weight goal. Then, it's time to start something new, like perhaps, bulking. Most BB's bulk in the winter and cut in the spring and try to maintain through the summer. Serious body builders only shred for competitions, otherwise they're trying to get bigger and bigger. Once you've learned how to cut effectively, you can always cut. It's always more difficult to bulk, because it require getting stronger, developing bulking weight training programs, and eating around the clock, which is quite expensive and time consuming.
