Beach, LOTS of us have issues with carbs - even whole grain ones. I can't help but think that you may be one of them. You mentioned that you've lost before on low carbs, hmmm, this kinda tells me I think you may want to experiment with giving them up again - and yes you LOVE your carbs, but maybe you need to decide which you would love MORE - the carbs - or the slim, trim, fit you.
I too LOVED my carbs, loved em' to pieces and in fact didn't think I could live without them. But the price became too high for me. It was no longer what I valued MOST. I wanted it. I wanted that slim, trim, active, fit, normal weight me. I wanted to give myself the best chance at the longest life with the highest quality of life. So I decided to give them up for the most part.
And guess what? I don't miss them. Nope. After a few tough weeks, they became a distant memory. And I no longer craved them or desired them. It was no longer an issue. It just became something I don't do anymore. And I'm fine. Perfectly fine. No regrets. I'm too busy enjoying the heck out of my life.
I do have grains on rare occasions now, but always with the knowledge that my weight WILL go up and that I WILL most likely stir up my wants for them once more. That is my decision and we'll see what I decide in the future.
I will tell you this - the anticipation of having to do something is usually much worse than the actual event. I would be shocked if you did not find this to be true in this particular instance.
If you want what you do not have, you must do what you have not done.
Another quote I love - you'll never achieve extraordinary results by taking ordinary measures.
