Stress eating happens for most of us, given the right circumstances. Even people who don't usually struggle with overeating turn to food when they're overwhelmed, overworked, or overtired. It's complicated, because when you're stressed, you don't have a lot of extra bandwidth to problem solve -- and your willpower and discipline are probably in short supply, too.
Start doing the things that make you happy now. Don't wait for that magical day when you fit into a certain dress size or are satisfied with the number on the scales to book your holiday to the beach or buy that little black dress. Live like you have already reached your goal, you will be happy and it will be much easier to achieve.
Rather than asking yourself if a food is low-fat, low-carb or low-calorie, try asking yourself: Am I truly physically hungry? What sounds delicious to me right now? Is eating this food being loving to my body? What seems like a sane, moderate amount? Is this what I would serve someone else who does not diet or overeat?
