One paradox of overeating, and the negative impact of such, is that it can be caused by either negative influences or positive ones. One person may overeat to compensate for loneliness, stress, etc. Another, or even the same person, may find themselves overeating at parties or other happy times primarily because of the availabilty of the food. No matter the reason, overeating causes obesity as well as many other health issues. More research is needed to study the relationship between moods and overeating.
(Note that "between" should be used for two terms, not three. If you have three, the word would be "among.")
