Great work on your progress! I will tell you giving up junk food is SO HARD, I was LITERALLY eating fast food 9+ times a WEEK, one time I went to my bank statement and highlited all of my transactions at McDonalds for one month and I had 63 flipping purchases.... IN A MONTH!!!!
Now I just make sure I don't get hungry, because when I am hungry I reach for the first convenient thing and if I don't have a meal or snack with me, the fastest thing to get is something from the drivethrough. Now when I go to school I bring 1/4 cup nuts in a baggie, a banana, and 1/2 cup high fiber cereal to snack on throughout the day, and I always plan what I am going to have for lunch before I get hunger pangs so that I don't give in and levitate to those "golden arches!"
It is really hard, but trust me it gets so much easier. What I found works is just staying away from fast food places at all, to me I cannot even get a Wendy's side salad because I will be tempted and get a frosty too. Now I go to wholefoods if I don't have a lunch with me and get a sandwich with a bunch of grilled veggies, lean meat, and mushrooms, and I always make sure I have a water bottle on hand.
Anyway, I hope this helps you! If you have any questions or need advice or just someone to talk to feel free to message me or stop by my diary
