3 month check up I hit my 60% mark but now having a hard time getting past 60-62 lbs. Any advice

Can you share a little more info about what you are doing? How many calories/carbs/grams of protein are you getting? Are you getting your 64 oz of fluid? What does your exercise look like? What do *you* think is causing you not to lose as much or as fast as you want? And what does your weight loss picture really look like now? Have you stopped completely or just had a little slow down? Not a lot to go on in your post for any of us to give advice . . .

Calories 600-900, I walk 3-4 miles a day. Fluids vary. I try. Protein I don't get the 60 grams. 50 is usually good for me. I weigh less in morning by 2 lbs but through the day I put that back on. So bounce from 168-170 daily.

You aren't even hitting 60 grams of protein? That's a real problem. I was easily at 100 grams at 3 months out. You should definitely work on protein and water and worry about everything else after you are on track with those two.
