Understanding Leptin

I was reading over Berardi’s hungry hormones articles and am a bit confused.

High leptin = low testosterone, and vice versa. ok got that

but increase calories (esp carbs) increases leptin.

fasting decreases leptin ( so would that increase T.

It seems that keeping calories constant without any fasting periods keeps leptin to high?

but than you don’t want to have it downregulate and get to low? so???

I am confused by this whole array of leptin.

Can Anyone cut to the chase?
