A method of modulating an individual's weight generates a randomized daily caloric intake value based on an individual's body composition and metabolic rates and the individual's specific weight management goals, including weight loss, weight gain, or weight control and eliminates the individual's foreknowledge of future daily caloric or nutritional intake goals. Once the individual's base metabolic rate is determined, a series of categories, each having a different daily caloric intake value, is calculated to provide a range of daily caloric intake values. A random or pseudorandom sequence of the categories is generated over a block of days during which the individual's weight is to be modulated. The category or its corresponding daily caloric intake value of a particular day is not revealed to the individual more than about 24 hours before a particular day.
