My advice is to drink lots of water (at least 3-4 L a day) and get some psyllium in your diet; switch to a vegan protein, cut out cows' milk altogether, and stay away from soy milk as an alternative. Coconut milk and almond milk are pretty good alternatives imo.
For your workout I think another day of squats and some dead-lifts will help a lot. I also think you should add another day of cardio even if its walking on the treadmill at a low-moderate level for an hour, followed by 30 minutes of a combination of core workouts, jumping exercises (skipping, squat jumps, ski jumps, etc...), and push-up variations.
Finally for your actual workout plan I would super-set your isolated movements to make better use of your time and get your muscular cardio up.
Good luck on your journey
