What is healthy weight loss? It's natural for anyone trying to lose weight to want to lose it very quickly. But evidence shows that people who lose weight gradually and steadily (about 1 to 2 pounds per week) are more successful at keeping weight off. Healthy weight loss isn't just about a diet or program. It's about an ongoing lifestyle that includes long-term changes in daily eating and exercise habits.
Indeed, as with any diet the early losses tend to be greater as much of this is simply water weight being lost. On average it would seem that a stone (14lbs) can be lost in the first 5-8 weeks of eating the 5:2 way, depending on factors such as your starting size/BMI and activity level.Following this initial loss our statistics show that the rate of weight loss slows down to a steady 1lb per week on average.hose with more weight to lose may find they can keep losing 1.5-2lbs a week for some time longer before slowing down and those with less to lose may well find it a struggle to even lose 1lb a week.
