Is it possible that if my protein intake is high it causes that I'm tired, sluggish??{and why??} what do you think, is here possibility?? I'm 5'6'108 and I consume daily between 120-130g protein. Is it OK by diet??
High protein dieting keeps my energy levels up when low carbing it.
I usually bump my protein right up when I take carbs under 150g a day (at 280lbs) and shoot for 400g plus.
I am usually only tired because I should be - ie, 2 hours of cardio, busy day, lifting session etc, which is why there is eph and caffine in the world
It may be worth trying to take up your protein level a little, it really depends on the rest of your diet. I find sat fats make me tired and sluggish as hell so I have those non existent as possible.
Protein will not make you tired. However... you need to supplement that protein with water. Protein will leech water from your system. Protein raises uric acid levels in the blood that your body is forced to flush out. Net result: your body becomes dehydrated.
Drink 3/4 to 1 gallon every day. Coffee, sodas, etc. don't count. I'm talking pure water. I'd suggest you pick up a nalgene bottle (search amazon for "nalgene") and drink 3-4 bottlefulls throughout the day. I drink 32 oz in the morning, 32 oz at work, 32 at the gym, and another 64 in the evening.
