The general rule for protien consumption/absorption is 1.5-2.0 grams per pound of body weight. This will keep you from being hungry, cuts cravings and keeps higher levels of nitrogen in your muscles. You should take a minimum of 3 shakes in a day. Right when you wake up, post workout and just before bed. I drink 4-6 a day and actually cut to 4 shakes when trying to drop weight. If your working out hard, this much protien will do nothing but help you. If your drinking shakes and sitting on a couch your wrong! You will put on spare tire weight if your not burning the extra calories. BSN is good stuff, but I feel whey is whey and casein is casein. Whey burns super fast in your system where as casein stays with you longer. Clear as mud? No gym today for me.
