NIce Loss and Congratulations!!!!! Not a GYM expert, but if you are meeting your daily protein needs even without a protein shake, then you are PROBABLY using mostly fat...my doctor tells me no one burns 100% of stored fat, that even in a good scenario it will only be 65-80% stored fat. (Hope i don't set off a BIG debate with that statement...LOL) I wish you a weekend filled with healthy choices AND affirming people!!!!
