I have a question regarding breakfast (or the lack of it).
Some fitness gurus like Ori Hofmekler - founder of the Warrior’s diet- argue that exercising on an empty stomach while fasting or before eating breakfast will result in greater fat loss, endurance and muscle growth.
Others - like Tim Ferriss- claim that eating breakfast first thing in the morning and exercising some time afterwards is the best way to build muscles and lose weight.
I don’t have a full answer for you (and would be interested to see one also), only some comparative studies of protein and carb consumption before compared to after working out.
“One study on 6 healthy and untrained volunteers, an essential amino acid (EAA) solution of 6g taken alongside 35g carbohydrate in a fasted state was significantly more effective in improving muscle protein synthesis (as measured by phenylalanine incorporation) when taken immediately before when compared to immediately after.”
"Pre-loading some protein, if in a fasted state, may be better than consuming it after a workout with little to no pertinent need to consume the protein immediately after the workout. "
