Now it has been recognised that the findings from 1994 where an oversimplification. Leptin is also produced by the stomach and placenta and receptors for this hormone are found  in many tissues. However, in terms of weight regulation the size and quantity of the fat cells are utterly important: more and larger fat cells produce more leptin. Leptin then signals through receptors in the hypothalamus, which is the control centre for our hormones in the brain, to restrict energy intake, i.e. appetite. Therefore, if this mechanism does not work due to a genetic defect or most commonly due to leptin resistance, caused commonly by years of yo-yo dieting or eating the wrong composition of foods, this causes the hypothalamus to change the body's natural Set Point, which may result in obesity or difficulty in loosing weight.  

Most of us are born with an optimum Set Point, which naturally maintains our genetic ideal weight. This is easily brought out of balance through inadequate and crash dieting and if the human body does not receive the correct type, composition and amount of nutrients within one day. Hence, the Set Point must be reset to its original setting, through a carefully customised and monitored approach, which is what the Set Point Diet stands for.

The Set Point diet cannot be compared with any other diet, as it is does not only calorie count and it does not exclude any important food groups. Every diet plan is tailor-made by Claudia Louch for each patient depending on a full health-check up including comprehensive laboratory blood tests.
