What kind of eater are you? Are you a "it's ok to eat like this I am on vacation", or "I already ate poorly today so I will continue eating this way all day, and start back on track tomorrow", or "I am not hungry but that looks so good- I am going to eat it."
The type of eater we are shouldn't change because we are happy, sad, it's Saturday, we are on vacation, or any other emotional, non- physical reason. Physical hunger and fullness are important feelings to get reaquainted with this year. I call it the Intuitive Eating diet, it's not a diet at all, it's just becoming acquainted to your physical cues of hunger and fullness and not letting any of your emotional cues of hunger or fullness get in the way. Eating when we are truly hungry and stopping when we are full helps maintain body weight and not result in weight gain. It sounds so easy, so obvious but if you eat intuitively you should not gain weight. So, eat when your body is hungry and stop when your body is full. You know your body best, don't make it starve or make it feel too full. Find the "just right" and eat to that point all the time this year.
