IF only works if you are in a caloric deficit. So if it’s not longer working then you aren’t anymore.
do not concern yourself with what you watch says you burn. not accurate.
I’d start tracking what you eat with consistency and accuracy for a couple weeks to a month. see what your maintenance calories are and then you drop them by a couple hundred to start and see if things move again.
eat as many meals as a day that works best for you.
eat adequate protein and fiber.
might be a touch Low on fiber. you should have at least 30 grams fiber a day.
The avocado, chia seeds and strawberries and banana has some but I doubt it’s enough.
Also what’s your goal? hard to say if this is good with a goal in mind.
Are you allergic to other nuts? or too expensive?
Maybe have a shake in the morning with a bunch of stuff in it and save the overnight oats for second breakfast.
it’s your day/week as a whole that matters. not single meals.
you need to be in a caloric surplus. one meal won’t do that.
so whatever your targets are for the day. hit those, and if you are gaining weight then you are in a good place.
I would download a tracker app. I like carbon diet app because it will give you appropriate targets to aim for and it has a built in coach you need to check in with.
I would start with a maintenance goal and go with that for a bit. you might see some body composition changes there.
also you need to resistance train with progressive overload.
you should rely on calorie deficit for fat burn. not exercise.
excercise for health, muscle retention or growth etc.
