Obesity has become a public health problem concerned by people around the world.According to the theory of energy balance and the TCM visceral manifestation theory of the physiological functions of the middle energizer，we probed into the reasons for obesity and discussed the intervention measures and treatment methods in daily life.The mechanism，role，and unique value of invigorating middle energizer in losing weight were described from the TCM visceral manifestation theory.The similarities of theoretical cognition between traditional Chinese medicine and Western medicine were explored to provide a theoretical basis for understanding and treating obesity.According to the TCM visceral manifestation theory and the concept of health preservation，middle energizer is the pivot of human energy metabolism.People can activate the spleen for eliminating dampness through a balanced diet，sooth the liver and invigorate the spleen by physical exercise，maintain the thin constitution by regulating emotions and promoting the functions of gallbladder and stomach.Accordingly，the middle energizer can keep the normal function of transportation and regulates the ascending and descending of qi.Then，the metabolism of phlegm，dampness，and fat is moderate，and zang-fu organs keep harmonious，with balanced energy metabolism，which facilitates weight control.In clinical practice，we can yield twice the result with half the effort by soothing the liver and invigorating the spleen，eliminating dampness and resolving phlegm，and harmonizing the stomach and promoting gallbladder secretion according to the actual conditions of patients combined with regulation of diet，exercise，and emotions.
