Emotional eating happens to quite a few people, at one point or another in their lives. You're to be commended for recognizing it and trying to get it under control. Good for you. (Believe me, I know -- there's nothing like chocolate when you're having a stressful day!! )
I always had a hearty appetite, but, not to long after my divorce I started dating a very nice and very funny lady. The problem was that food was her focus. All our activities centered around food. I put a lot of weight on rapidly. I knew that this was an unhealthy situation for me, so we broke up.
(much longer story that I won't bore anyone with) Since then I have been able to continue to lose weight in a slow, orderly fashion. Over the last 5 years I have shed 85 pounds and still have a large chunk (literally) to shed.
Doctors started to get concerned about my weight loss. Not because it wasn't good to lose weight, but, with my health issues they were concerned that it was related to that. I assured them that in spite of not working really hard at losing, it was deliberate and involved eating the same stuff, but, in much smaller quantities and walking, golfing, walking, golfing and more walking and golf. I allow myself a Hershey's Dark Chocolate Candy Bar daily. One of my only real motivations to do good the rest of the day.
I also have a theory that we, as a society consume way too much water. People are drinking gallons a day, but, they don't urinate gallons a day. That water goes someplace. Where it goes is it expands existing cell to hold the water and even creates new ones. Water weight is a real thing. Back in the day when we worked the fields in the hot sun all day, water was essential, but, even then they didn't consume as much as we "office workers" do and we don't usually even break a sweat. Now don't get overly excited about my comments, it is just my opinion, but, to me it makes a ton of sense. It's a wonder we don't drown ourselves internally.
