My advice? Go back to basics of your "forever plan".
Eat ONLY the amount of volume they tell you per meal. If you can eat only 3 meals per day and meet your protein needs do so--cut out the snacking!!! Clean your pantry, fridge, freezer out. Recommit to your new body! You deserve this! Quit cheating, break up with your old ways again, kick the crap to the curb!!!!
Weigh yourself daily.
Plan your meals, and log every bit in a fitness app like MFP.
Exercise daily.
Eat to your rules and get in the amount of protein your doc and RD told you to eat daily and make sure you are taking your vitamins. You might also call your surgeon to see him/her and get a referral to your RD for a new plan to combat this.
1. Eat 2-4oz of lean dense protein per meal.
2. Eat 1-2oz of al dente veggies per meal.
3. Eat a little healthy fat with every meal (1tsp of evoo or avocado oil or butter OR 1oz of avocado OR 1/2oz nuts)
4. No drinking 15 minutes before a meal or at least 1hour after.
Get enough sleep each night.
Try to deep breath and get stress relieving things on board.
Congrats on your losses so far and on recognizing the need to get back to being serious about health!
