Your right, it may not be for you. There are tons of reasons why your metabolism cannot tolerate going an extended amount of time without food. Most of us stick to it because it’s the easiest for us and our metabolism. If your getting Shakey or having adrenaline spikes from skipping a meal that’s a very clear reason you should not be intermittent fasting.
Just curious. I didn’t see you mention exercise anywhere in your post. Are you doing anything like that, cardio or walking, lifting weights? I know a big part of my IF results had a lot to do with me also starting an exercise routine. Anyway, just a thought.
If after sticking with it for a while you still haven’t adjusted, then time-restricted eating may not be the method of weight-loss best for you. Every diet is a means to the end of achieving a calorie deficit through /r/cico and different people prefer different methods. IF helped me a lot, but plenty of people lose weight without it. You could do keto, you could eat primarily high volume whole foods, you could do more cardio, you could track your calories (my personal recommendation) and then eat whatever allows you to feel good whilst hitting your goals.
It can take some trial and error to find what helps you keep a calorie deficit while keeping your sanity. IF is an excellent tool for lots of people, but it isn’t magic; and it’s okay if it’s not the method that works best for you.
Did you gradually get to OMAD or did you jump in? Maybe you need to adapt to fasting over time. For some, it’s easier if you start with a 12 hour fast, then as you adapt, lengthen the fasting time by 30 minutes to and hour at a time, gradually getting to OMAD. Some people need to eat earlier in the day and fast later in the day. Also, nothing wrong with opening your window with a small snack and eating your official meal later in the window. OMAD does not have to be one plate full of food. Some people need two meals a day for awhile first.
