Abstract: An electronic device for managing a health plan comprises an electronic display and a processor configured to maintain a meal plan to be displayed on the electronic display. The meal plan has a plurality of meals as guidance for a user to consume during a day. The processor is further configured to switch a meal of the plurality of meals with a specific meal offered by a specific entity. The specific meal can have substantially the same nutritional characteristics as the meal being switched out. A computer-readable medium including instructions stored thereon, that when executed by a processor may cause the processor to manage a meal database. A related method for managing a health management system is disclosed that includes switching the meal from the meal plan with a specific meal from the one or more specific meals.

Abstract: Methods and systems of establishing a program to maximize weight loss include determining an energy deficiency and an exercise regimen for a particular female individual based on an increased concentration or level of at least one ovarian hormone, such as an oestrogen or progesterone. The increased concentration of the at least one ovarian hormone may be determined by calculating a phase of a menstrual cycle of the female subject. The daily energy deficiency may be calculated and an exercise regimen determined based on the phase of the menstrual cycle. By decreasing the daily energy deficiency and increasing the exercise regimen while the concentration of at least one ovarian hormone is increased, weight loss (i.e., fat loss) may be maximized.
