This article describes the results of pre-project analysis of the subject area and proved the feasibility of automating the calculation of the nutritional value of the food diary for a healthy and fulfilling life. It is proved the relevancy of training programs automation service development considering the physiological features of the person. The existing similar software products are considered. The structure of functions of the developed service is given. The purpose of the work is automatization of keeping food and training diary, the interaction of users and trainers, as well as further development in order to implement the program in schools and universities. Tasks: development of a web application of food and training diary, which will help to automatize the process of forming the user's diet and plan the training program. However, the implementation of multi-functional web applications requires a systematic approach, which involves the definition of the necessary tools and technologies. Cost, speed and quality are the main criteria for creating and selecting tools and technologies for development. Therefore, an important task is to create a set of tools that speed up the development process without significantly reducing reliability and security. Research methods: theoretical analysis and generalization of scientific and methodological information sources and documentary materials, the survey of specialists, the study of video materials of competitive activity, testing, methods of mathematical statistics. The following results were obtained: a multifunctional web application was developed; electronic service that allows the athlete to identify the physiological characteristics of his body, to determine the required level of daily calorie intake and, based on the set purpose, to form a training program, to determine the diet and daily routine. Conclusions: the scientific novelty of the results is the following: it was created a cross-functional diary that stores the necessary information about the progress of training and food, helps to create the training program and to systematize sports activities. The given list of service functions will allow to fully demonstrate its competitive advantages, as well as to solve the problem of automatization the user's diet formation process and training program composition, considering his physiological characteristics, lifestyle and daily routine
