This is primarily done by altering neurotransmitters in the brain. It belongs to a group of medications called serotonin-norepinephrine reuptake inhibitors (SNRIs). It affects chemicals in the brain that influence weight maintenance, approved by inhibiting reuptake of serotonin, norepinephrine and dopamine in a ratio (1:5:16). To keep you from getting too angry or gorging on the food that turns into fat.

This means it prevents the uptake of norepinephrine, serotonin and dopamine through inhibiting presynaptic neurons that convey them thus resulting in a greater abundance of these neurotransmitters in synaptic clefts (space between neuron cells). Therefore, the use of sibutramine after eating results in much lower than usual consumption and absence from additional calories that eventually clog up that is exactly how obesity occurs.
