Congratulations on your wedding - I'm sure you looked beautiful. I am an exceptional yo-yo dieter myself. When I do brief mental calculations, I'll bet I've gained and lost 600 pounds over the years. For most of my adult life, I have been battling with the same 20-30 pounds over and over, and it's not getting any easier as I get older
Everyone says we need a plan, and we need to stick with it. Do you count calories or follow a specific diet? For myself, tracking everything I eat has always worked (when I'm not too lazy to write it down, and when I do it, it does work). I also find that eating a lower carb diet really helps. When I throw in processed carbs and sugar, my cravings go out of control. I would write down what your daily plans are for the day (Breakfast, lunch, dinner and snacks), and don't let hubby convince you that Burger King is alright.
Exercise is also very important. The endorphins and seratonin and dopamine that are released when we exercise not only make us feel better but also help keep cravings in check. I think a lot of us try to overexercise - more is not necessarily better, but we should try for 30 minutes six day per week. Oh, and not just cardio - weight train 2-3 days per week.
I have a hubby who isn't very supportive, either. He is a very dedicated weightlifter, and has mastered the art of mindful eating. I cannot do that - once I eat a piece of candy, my day is blown. After our many years together, I feel he has given up hope on my ability to ever permanently succeed.
But, I know we can do it! We are works in progress, but with persistance, we can succeed!
