Abstract

During diets, people basically try to change their living habits to lose weight, such as restricting caloric intake and increasing energy consumption through exercise and activity. This could truly be considered a hostile act against corpulence in modern society. For many women in particular, the act of dieting is essentially wishful thinking in their daily lives, and selecting easy diet food would seem to be an obvious way to achieve this wish. However, while the diet effect must be clear when selecting better diet products, there have been no findings on diet effect that consider the effects of age. In this study, we used product evaluation, sex, age, height, body weight before use, body weight after use, duration of use, and other factors in data from the T. M. Community Co., Ltd. (TMC) review site “Diet Cafe,” which specializes in diet products. We analyzed the changes in the diet effect with age by applying the wavelet interpolation model to the change in body weight and the percentage change in body weight in subjects aged from the 10s to 60s. In addition, with the curves describing the amount and percentage of the change in body weight, we investigated the inflection point (critical point) in the diet effect with age by deriving velocity curves as differentials. The WIM was applied to the age-related changes in the size of the diet effect, and the identification of the age of 30 as a critical point in the diet effect from the behavior of the velocity curve may be considered a finding derived for the first time. The slowing of the velocity then becomes consistent about 10 years after the critical point, at around the age of 40, from which it may be proposed that the age of 40 is a true transition phase for women.
