Heres mine for example..this is me trying to add mass..
10am: 12 jumbo eggwhites (1 yolk) 1.5 cup oatmeal
12pm: 9oz chicken breast, 12 oz sweet potato
2:30pm: 9oz chicken breast, 1.5 cup oatmeal
5pm: 10oz tilapia, 12 oz sweet potato
7:30pm: 12 jumbo eggwhites, 1.5 cup oatmeal
9:30 (pwo shake) 60g whey, 60g dextrose
11:00pm 8oz chicken, 1 cup oats
Sumthin like that
And no, I do not sit around and eat every 15 minutes. I keep this same diet when I am working...and presently I am away from my apt for 5-6 hours during this..I bring my food with me.
Saying, "I can't get any bigger than 150lbs" is a crutch.
I have a friend that was your height and 150 and we got him to 190. Still natural as well....took about 2 years.
