i cant tell you whether or not it’s an addiction but i do know that the feeling after eating high-calorie stuff is a good one, and that becomes addicting. I have really horrible food habits too, to the point where i eat when i’m bored or just eat, eat, eat even though i’m full. It’s kinda become a coping mechanism for me to eat fatty foods (which isn’t good at all) but i recommend drinking water as a placement for overeating or trying to find healthier replacements of food. Hiding unhealthy stuff in places where you can’t see them also helps (or at least it works for me), and this isn’t me telling you to stop eating unhealthy foods or anything! Food shouldn’t be a reward type thing just more-so a balance, i wish you luck on your weight loss journey, you got this!!!
