Hi all

So I am 30 lbs in on my journey to 100+ lbs lost. I feel like I am hitting a plateau and am looking for some advice on how to modify my diet and exercise to continue to weight loss.
My diet currently consists of 2 protein shakes (1 for breakfast, 1 for lunch), 2-3 healthy snacks throughout the day, and 1 well-balanced dinner everyday. My calorie intake ends up being around ~1500-1700 daily. FIRST, before anyone discredits the shakes, I really enjoy having the structure and an ultimate go-to meal. It has been working very well so far and I am not hungry throughout the day. I have a very crazy schedule so I like the convenience.
I go to the gym 5-6 days a week (depending on work schedule) and burn anywhere from 600-1000 calories between primarily cardio and weight-lifting.
Any suggestions from people who have struggled with this when getting to a certain point? I feel that I could use a change in either my diet, exercise, or both to keep me making the progress I have been getting used to seeing. Any help would be appreciated!
