Are they related? Well, yes and no. People think that because they age, they automatically have a slower metabolism than when they were younger. Well yes, your metabolism does slow as you get older, but not for the reasons most believe. It does not just slow because you get older, but instead because you stop moving as much.
Many people suffer with cellulite. These are the cottage cheese-like dimples that are usually most evident in the hip, bum and thigh area. What I always recommend is to do two weeks on a detox diet and then make BIG changes to your training routine. Individuals who train intensely for short periods (anaerobic) tend to have fewer problems with cellulite than most.
