RDS Calculator
Introduction
Significant health benefits are associated with modest weight loss of 5-10% of bodyweight. Weight loss success should therefore be considered when a 5-10% weight loss target is achieved and maintained.
The Re-Defining Success (RDS) Calculator is a useful tool to calculate a target body weight following a 5% and 10% weight loss from present weight. Once appropriate weight and waist reduction targets have been calculated, the RDS Calculator can be used to print a personalised change plan and weight management progress record.
The recommendation for a healthy rate of weight loss is 0.5-1kg (1-2lb) per week. The RDS calculator uses this recommendation to suggest an appropriate and realistic timeframe to reach 5% and your 10% weight loss targets.
