Trust in Father to direct my heart.  Do not do things to purposefully hurt myself.  [Extremely ascetic practices can do so...including fasting.  And fasting can be destructive.]  Try to remember and apply all the lessons and knowledge and Wisdom Father has provided.  Do not allow doubt to be cast upon the Truth of matters which are solid.  [Doing so means to be willing to step off of the Truth, which I will have none of, and to be unstable or uncertain, indecisive.  If I make a decision and believe and know something as true in my heart, I must stick to it.]  James 1:8

By trying to consider why I should even allow myself to enjoy food, even in moderate amounts, or in a way that is reasonable and okay, I delve into territory that belongs to Father.  There are limits that must be heeded and realized.  Those limits aren't there to harm, but to help.
