Hi Jen
Well done on breaking through plateau- it's a great feeling isn't it?!!
It sure is! Awesome feeling!

I hope it keeps going strong for a while .. at least to get me into the 360's

That's my next goal: 369 lb.
Sounds like the fasting is going well too - sometimes we just need to change things up a bit to encourage the body to use the fat. I like Fung's analogy about the fridge/freezer and how the body will always go for the fridge which makes total sense.
Keep seeing how you go with this new routine and give yourself a while to get used to it. I found the psychological aspect of not eating the hardest part - especially when nudging toward the 23rd hour but we can break through that mindset. Definitely doing low carb is the perfect partner with IF.
On my 18:6 fasting days I eat at 8:30 AM (shortly after I wake up) and then at around 1PM.
On my 23:1 fasting days I eat breakfast at 9 AM (about 800 calories 10g carbs 50g protein) and that's it for the day.
So the 8 hours of sleep before the breaking of fast actually helps me out quite a bit--makes 23 hour fasts easy. And I feel great all afternoon up until I go to bed. In ketosis, and fasting state.. happily burning fatty acids and keytones. No hunger at all. If I do get a little hunger, I drink water. Or make a cuppa. Or mug of coffee. Or a cup of homemade chicken broth (keep it frozen in baggies in the fridge). Those always do the trick for me.
Also, skipping dinner works out great for me because my boyfriend works from like 4PM to 2AM. So we get to eat breakfast and/or lunch together every day -- homemade healthy whole food meals. He's losing weight as a side effect of my diet.
I actually feel liberated from food and don't even think about it. Last thing I ever ever think of is a refined carb of any sort.. if I do end up snacking on something (which I don't when I fast) is blueberries maybe with some heavy cream. But like only 10-15 blueberries or so.
Please don't worry too much about the calories. Like Fung said, weightloss is about lowering the insulin and we need to aim for foods that have minimal insulin impact.
I don't worry about calories at all. I use an app that tracks everything I eat: all the carbs & protein grams (which I am concerned about). And it gives me the calories as well. I have eaten without looking at total calories and it is always usually right around my goal calorie limit due to satiety alone. So I am all good there.. not starving myself.. never feel hungry. No worries. I feel better tracking my calories to make sure I don't overdo it. Also, remember I'm fasting on ketogenic diet.. so calorie restriction can't hurt me. And if I do absolutely feel hungrier for some reason a particular day, I will eat an extra couple hundred calories above my usual, with no worries at all. Again, the main thing I'm tracking is carbs & protein, which are very important to track.
You can do this. We can do this!
Keep going xxxx
Yes we can. Keep goin' as well!
