I haven't seen any correlation in my own efforts, but that doesn't mean there isn't one.
It's hard, though, to know how you might be able to kick start more of a loss without knowing more about your age, weight, and what you mean by not losing much, etc. Try out this calculator for a look what kind of losses you can expect based on all those factors:

Also, it might be a matter of the specific foods you are eating. High sodium can result in water retention. Some people lose more slowly on a carb-heavy diet, whereas others are less impacted by carbs. Others here may be able to offer some specific help and suggestions if you post a few days worth of your food intake.
