When it comes to RTM and beyond, don't worry about it for now - by the time you reach it, you will be a very different person! The voice that says things like "will I be able to keep it off, I worry about maintaining, I don't like healthy food" etc is just your inner "fat" voice that doesn't want to let go and tells you these things. You can and will like healthy foods, you just have to learn to like them along the journey
Stick to the diet, and that voice will get quieter each week.
I never thought I would be a fan of "healthy" food, Uni was great for me as it was an excuse to eat all the crap I loved! BUT, 24 weeks later, and now I look at a lot of the things I used to eat and feel sick; looking at healthier foods is great, they look more appealing, smell great and knowing that they are good for you is a bonus too!
Your tastes will change while you do LL; think of it as "resetting" them after all the mass-sygar-and-fat warping they have been through. Once you are fully underway with Ketosis, and not feeling the hunger, you will learn to really *listen* to your body and what it tells you it wants instead of your head dictating all the time; and I tell you, your body will never EVER tell you it wants crap like we all used to eat, that is 100% in your head.
I think the start of LL is the hardest for many reasons, not least because we are (on some level or other) afraid of the changes ahead of us, and as much as we want to change and lose the weight, the reasons we gained the weight in the first place are still present, and give you all these doubts.
It sounds strange to say it, but really, while in the abstinance stage, you have to ignore your own thoughts and just *get on* with it. Only you can decide to put something in your mouth, and no matter what the voices might say, you don't need to do that.
Yes, a bit hypocritical of me to say that after my lapses last week, but it's true, WE are in control of ourselves, no-one else! And life wil continue, fat or thin, with or without doing LL; the difference is all up to you
