The amount of weight lost depends on a number of factors including starting weight, activity levels, compliance with the program etc.
As a guide from the more than 14,000 people who have participated in Healthy Weight For Life programs, it is expected that if the program is followed consistently, you should see at least a 5% reduction in your starting weight by the end of week six and be approaching an 8% reduction by the end of the program.
However, success relies on consistency and perseverance and the exact amount of weight lost varies between participants.
