Nutrition state elevation method and nutrition state elevation system calculating areas of the muscle region image and the fat region image

Provided is a nutrition state elevation method including: performing training based on a plurality of abdominal medical images for training, a plurality of muscle region labeling data and a plurality of fat region labeling data to generate a muscle segmentation model and a fat segmentation model; performing training based on a plurality of muscle region areas for training, a plurality of fat region areas for training and a plurality of prognostic nutrition index categories for training to generate an index classification model; segmenting a to-be-analyzed abdominal medical image into a muscle region image and a fat region image by using the muscle segmentation model and the fat segmentation model; calculating areas of the muscle region image and the fat region image; and using the indes classification model, for a muscle region area and a fat region area, to generate an index classification result indicative of one of the plurality of prognostic nutrition index categories by using the index classification mod
