Time for some tough love... brace yourself.
If you want this surgery, you need to put your foot down and force yourself to stop what you're doing. You were given a few more weeks to show that you CAN make the necessary changes in your eating behaviors that will lead to success with the sleeve... and you're gaining... again?
I get it, I had a few false starts when I was getting ready to do the pre-op diet (clearly you're also an emotional eater if the stress from this is driving you to eat more), but at some point I hit that wall where I knew I had to suck it up and just do it or I was going to run out of time.
You have ALREADY run out of time... all you have left is a couple of weeks before your final nut appointment and then all the documentation will go to the insurance company. They're going to review your file and will make a determination based on how confident they are in your ability to be successful with this surgery.
If they see that you've done nothing but gain when you're supposed to be losing, the first thing they're going to think is "If we dole out the cash for this guy to get the surgery and he eats more than he should post-op, we're going to have to dole out MORE cash to pay for the complications from a leak."
THEY WILL REJECT YOU IF YOU DON'T LOSE WEIGHT!!!
What's more important, instant gratification from eating or getting this surgery? What's going to help you more?
You need to sit that tempter tantrum throwing kid in your head down and tell him no, he can NOT have that hamburger, french fries, pizza, whatever right now. Someday he will be able to again (in smaller quantities), but NOT RIGHT NOW.
I don't know what else can be said to help, except to tell you how I lost the weight pre-op. This is what I eat religiously for a month leading up to surgery, I lost 20lbs. You could probably drop 10 in a week or two if you haven't lost anything yet:
Breakfast: Unjury Chocolate Splendor protein shake (2 scoops in water)
Lunch: 5oz/slices of chicken (deli) and 2-3oz of cheese (cheddar, mozzarella, colby jack)
Afternoon snack: Unjury Chocolate Splendor protein shake (2 scoops in water)
Dinner: 5-6oz of meat and 1-2cups of veg (usually broccoli)
Dessert: Sugar free jello or popsicles
1.) Get yourself a reusable watter bottle (Nalgene makes good ones) and keep it with you at all times...monitor your intake and make sure you're hitting 64oz minimum every day.
2.) If you don't like regular water, try Crystal Light, Mio, Propel Zero (grape is my favorite). Keep packets and your water bottle with you at all times and drink NOTHING ELSE.
3.) Pick up a couple of Blender Bottles or Shaker Cups for your protein shakes... these are your friends and will be for quite some time if you're approved.
4.) Sign up on MyFitnessPal.com and log everything that passes your lips. Keep your carb count under 30g/day and your calories under 1200/day (don't worry about the other values).
If you can follow this starting now, you might actually drop some weight before your final appointment.
