I think I was really lucky and by sheer luck decided to take up running and it toned my body as I lost the weight, so I went slightly saggy for a week or two but then the running toned that section up and it just kep working 😉
When I increased the distances I was cheating a bit some days my total calory intake. Was around 1,200 and I ran off 1,500 so I had days where I hand a negative intake 😉 they helped the diet.
