A computer implemented method for interactive weight management that includes generating a number of sub-goal weights g0, g1, . . . gn based on a current weight Cw, a desired weight loss amount (ΔW), a desired weight Dw, a curve tension r, and a timeframe (τ) in which the weight loss amount (ΔW) is to be achieved, wherein the timeframe (τ) includes a number (n) of time periods that each correspond with a pair of successive ones of the sub-goal weights g0, g1, . . . gn. The method includes sending the sub-goal weights g0, g1, . . . gn and the number (n) of time periods to a weight measuring device that is associated with a user. Based on the condition Wa1>gi
