You've certainly not made it up buddy as I've heard it before and remembered the amount that the article you link to refers to as the most common.

Defo trial and error. I'm not convinced that 6 meals per day is better than 3 double size ones. Also don't forget that different types of protein are digested/absorbed at different rates. It gets very indepth and for hibbybuilders such as us we would not be seeing any difference!

As for getting fat, keep the carbs low to moderate and you will be fine. Getting fat then lower carbs. Protein will not be stored as fat, providing you are taking it clean. A shake with water for example as apposed to a beef burger! Keep it simple for we are not at a level where getting anal over shit is not of any benefit to us at all! Just confuses stuff and takes the fun out of what is supposed to be a fun hobby!
