A part of recovery for myself was realising that the body is always burning energy no matter what you are doing. I felt like I could only justify eating something - even if that something was still extremely little - if I had been active and done something physically. But also I felt like I could only justify and be somewhat ok eating chocolate or anything other than a safe food because I needed to gain weight. I thought, once I reached my goal weight I could never eat any of those "treat" foods again.
That was not the case. I.e i can still eat any types of food, but all foods in balance and moderation and it's the same for you. Food needs to be eaten everyday no matter what you do.
You may lay in bed sleeping all day but your body will still burn a whole lot of energy keeping you alive I. E your BMR which for most people is around 1200-1400 which is the energy amount your body used just to keep you alive. I.e energy to your organs so they can keep working. So even if you do absaloutly nothing you still need to eat. And then of course if you just do basic things like go to work/school, do the dishes, food shop, cook food, take out the rubbish all of that adds up and most people burn around 1800-2200 just by going about their day. Of course calorie requirement is so different for everyone, for example if you have been eating very restrictive your body will have adapted to that and won't expend as much energy doing things because it doesn't feel safe enough to do that. But also I don't want you to go about your day just thinking about burning calories or doing 110 things each day to burn more. I made that mistake in the past as well, I would constantly be doing things because I thought just sitting still wouldn't burn calories... but yes it does.
Of course this post can be taken in the wrong way, I don't want you to focus on burning calories or that every movement is thought of calories burnt. More that I want to make you aware that even if you do absaloutly nothing you still need to eat. And even if you don't need to gain weight you still need to eat. Everyone needs to eat. Of course different portions and different amounts based on many factors but you don't have to eat just salad and cucumber because you are a normal weight or because you haven't been active. Your body needs daily fuel.
I think following hunger and fullness is the best and that is what will lead to balance, for example Somedays you are more hungry and some days less but there is a long term balance. However if those signals aren't working as they should then sometimes you just need to make yourself eat even if you don't feel hungry just because your body needs energy!!!
You don't need to earn food. You don't need to compensate for not being active. You need to find a balance with food and most importantly change your thoughts regarding food and intake!!!
