Q

What are the hormonal effects of having high body fat during a bulk?

A

Having high body fat negatively impacts your hormonal environment, primarily through increased insulin resistance and elevated estrogen levels. Insulin resistance reduces the effectiveness of caloric surpluses for muscle protein synthesis, while higher estrogen levels can hinder lean mass accrual. Additionally, lower testosterone levels at higher body fat percentages further diminish the anabolic response to training.

This is one answer. The complete system — the psychology, the biology, and the method — is in the book.
