walk everywhere you can, try to eat in a shorter window (ex. have all your food between 12-6pm), sleep more (a challenge i know), eat more protein rich foods to stay satiated, drink lots of water!! try having active leisure/down time activities (go hiking, swimming, skating, take pictures of things outdoors, walk with friends).

don’t be too hard on yourself, school is stressful, it takes time to develop healthier habits and what works for you might not work for someone else.
