dont get discouraged. Though there are plateaus, the scale is not budging for a reason and i am sure that you know what those reasons are. Its okay tomorrow is another day. But you have to have a plan. If you dont already do so, start by writing down everything you eat. It can sound cliche, but it is cliche for a reason because it flat out works. Almost everything has a calorie count (except celery) and that one serving of something might actually be 2 or 3.
My other piece of advice would be to change up some of the foods that you are eating. Hit the grocery store and maybe try 2-4 new foods. When i get in a food rut, i find that the same amount of food doesnt fill me up anymore and I go back for seconds. But when I try a new recipe or food, I am in a "taste tester" mode and full way sooner.
Lastly, remember the reason you started losing weight in the first place. that reason could have changed over time, but its good to know why you started. So whenever things get tough (and sometimes they have to before they get better), you know there is a bigger picture, not just one photograph. You will begin to rethink that scoop of ice cream or slice of pizza and the scale will go down. We promise
