Be ready for solid bulk weight - lean muscle comes slowly but surely. To lose weight, eat less, still as often, consuming the majority of your calories early in the day. Though contrary to popular opinion, many doctors and top bodybuilders I've conferred with agree. Don't let them be a substitute for a meal or become a habit. Good snacks are fruits or vegetables, low fat muffins, protein energy bars, nonfat yogurt, whole wheat bagels, cottage cheese, etc.
Excessive sugar plays havoc with our insulin metabolism and leads to fatigue and fat storage.
Eat a small easily digested meal 30-60 minutes before you train. With complex carbohydrates in your system, you'll train harder, longer and with more enthusiasm. You won't experience low blood sugar jitters or dizziness - you will experience a great muscle pump and probably get that last rep. After a long day's work, protein shakes and BCAA's are the kings. It's also a good time to restock your creatine stores.
