Honestly? My suggestion would be to contact your weight loss team and ask them to delay submitting for approval with your insurance for another month. That will give you the chance to adjust to a diet that will get your weight down below where you started off and start some exercise.
While I was still waiting to meet my reqs, my diet was one 30g protein shake at 9am, a 20g protein bar at noon, a cottage cheese cup/low-sugar greek yogurt/another protein shake or bar at 4pm, and then 5oz of lean protein and 5oz of veggies at 7pm. I'd generally end up between 1000-1200 calories. For exercise, I would just walk outside for about 30-45 minutes since the gym was not an option.
Couple that kind of a diet and routine with delaying submitting to insurance for 4 weeks and you should get back below where you started.
