Yes, it will decrease as cellulite is due to a layer of fat so the less fat = less cellulite. However, skinny people get it too so you need to do leg toning exercises, drink lots of water and use a body brush on your legs everyday (brush upwards in a circular motion) to break the fat down. I need to start doing this, but I'm a lazy heif. Caffeine is suppose to be bad for cellulite, so cutting down on that could help, yet I don't see why like the other reasons.
