Leptin is a hormone produced by the bodies fat cells. It exerts its effects in the hypothalamus in the brain (which controls hunger levels). It is used by the body to regulate bodyfat storage and metabolism. Release of leptin is a signal to stop requesting calories (shut off hunger). Constant overeating causes a constant release of leptin. Over time this can and will cause sensitivity issues to leptin (as with anything detected by the body to be in overabundance). If the signal is not well received then the body will continue to remain in storage mode (hunger) and conserve calories (lower BMR).
There is no need for concern when the diet is structured properly. Nutrient timing is actually more beneficial IMO regarding this topic. You are essentially giving the body what it needs when it needs it so that you are partitioning nutrients in a preferable manor towards our goals. We should do as much as we can to optimize nutrient partitioning. This means that we are building muscle and keeping fat low (obviously). We are creating a constant need for calories by training and giving it what it needs for repair and growth AT THAT TIME (which is why carbs are not uniform throughout the day). This predominantly sends our calories towards muscular repair and not towards fat. More muscle = higher BMR = furthering the effect. Lower bodyfat levels will have your leptin levels low and your hunger high (body senses need for fat so does not release the "satiety hormone" aka leptin). CREATING hunger is our goal, but we must at the same time direct nutrients where we want them.
