Please don't set yourself up with an unsustainable lifestyle. Life is about flexibility and adapting yourself to the moment, not trying to bend every moment to conform to you.
You have found something that works for you (and that is GREAT!!), but you can't live in fear of deviating from it a bit every now and then.
Think about it, you are worrying over a couple of strawberries and a piece of cake that you might eat
months from now. Your body is not suddenly unable to handle a teeny bit sugar or non-plan carbs. You have lived your whole life consuming them, and while you might not have felt the best, and was at a weight you didn't like, it's not like you were at death's door or anything.
I do IF, and I do it pretty religiously. (I know you do too
) My family knows my eating window, etc,
but I leave a space in there for real life to happen. I give myself 'get out of jail free' cards of sorts, and can randomly have a couple days a month where I don't follow the eating window.
A few weeks ago my pregnant SIL was having a really tough day and just wanted to set down and eat lunch somewhere. I didn't say "no, I don't eat till 4pm and you know it", I just realized it was an important moment and relaxed and enjoyed my lunch. Could I have said, 'no you eat, I'll go with you and drink unsweet tea'? Yes, I could have, but my diet is only part of my life, and I refuse to allow it to take over my life and make everything else conform to it.
I have to live and you do too.
Let's face it, our families and loved ones have to put up with a lot when we are on these diets. Sometimes it's important to do little things that show them we care for
them too. It's not just about them supporting us, it's about us showing them that we love and care for them too, and recognizing how much they put up with. Sometimes that requires us showing them that we are willing to break our little absolutes, just because they are
so important.
One strawberry. One piece of cake. One lunch with less than perfect ingredients. These are all so abstract and small within the overall view of things.
You've dieted like you have to give yourself CONTROL of your life, NOT to lose control by living in fear of the smallest things. You have earned that.
Live life to the fullest, and enjoy every moment!
