The importance of a healthy diet cannot be stressed upon enough! Whoever said "You become what you eat" knew what he/she was saying! Include everything in your diet - do not totally leave out a particular kind of food because it is fattening or 'less healthy'. Everything is good in moderation. Feel like having a burger and fries ever! (Unless of course, if you don't LIKE burgers and fries!) But 'being strict' with yourself is not a very nice thing to do!
Emotional eating is really not something to be scared of tackling. Neither is it something that should upset you! Have faith in your ability to deal with life, and you will be able to wriggle yourself out of the clutches of emotional eating.
