I used to be morbidly obese and am slim.
May I make a suggestion?
I would try and really thoroughly add up my calories for a day. I'm not suggesting living like this, because life's too short, but just do it absolutely meticulously for one day and see what numbers you come up with.
Reading your posts, the 16:8 is fine, the steps are fine, but the food intake for the day you listed is a lot more food than I'd eat in a day to lose or even maintain, tbh.
With your lunch you also ate a bowl of porridge.
With your curry, you ate rice and naan.
If I'm maintaining my weight I don't weigh and measure food, I try to be pretty relaxed about what I'm eating, but I have in the back of my mind, that I need to be moderate in my choices rather than go overboard.
So If i'm having a curry, I would have a portion of rice OR a naan. Not both at the same time. Because that is the same as eating a sandwich AND a bag of chips at the same meal. Which is delicious but a lot of food and I can't eat like that very often without gaining weight.
And if I am trying to lose, I would still have the curry and if I felt like a naan, I'd look up the Kcals, weight it and eat 85g of it, which is about half a big one. This is about 280 Kcals. If I eat the whole big one, it would be 500+ kcals, which is too much for me when added up with the calories in the curry itself. Next time I wanted a naan, I probably wouldn't weigh it as I'd know if I have half a big one that's about right when I'm trying to lose weight.
Trying to eat a 'cleaner' diet is good because you get more food for your calories, (1 bar of a kit kat is more calories than a whole punnet of raspberries which would take me 10x as long to eat, for example), and I think if you are eating lots of protein and good veggies it does help you to crave the crap less BUT 'eating clean' ie only eating the good stuff is deadly, in my experience, as I can't keep it up and its just a binge waiting to happen. Trying to eat moderately, feeding your body good stuff with some more indulgent treaty food factored in is sustainable in the way that 'regime's' of any kind are not.
