The evidence is clear that long term calorie restriction, most notably extreme calorie restriction, will cause you to lose weight intially (in most individuals) but then yes your metabolism will compensate and you’ll just gain the weight back typically. This is on display with shows like “the biggest loser”. They exercise and calorie restrict with success, but almost all of them are back to their weight a year later. I would say though even Dr Fung, who is a huge proponent of disregarding calories, says the metabolically unhealthy like he deals with should not be eating excess fat due to their impaired leptin signaling. A healthy person will store some fat, increase leptin to stop storing and burn the rest by increasing metabolism. This is why some could eat 5,000 calories and not gain weight. But the metabolic unhealthy person is leptin resistant and will continue to fill fat stores and remain in a slow metabolic state. He is pretty clear that these people shouldn’t just be snacking fat bombs all day. I would also add that he actually says these people need to eat less but to accomplish this by fasting, which doesn’t seem to have the same metabolism slowing effect of long term calorie deficit eating. The takeaway for me is the protocol is very different for a lean, metabolically healthy person and an obese, metabolically unhealthy person like Dr Fung works with.
I'm stuck! Please advise
I just wanted to point out that dark green vegetables definitely contain protein. So you can get protein from there.
The metrics that you are following aren’t necessary. They are just helpful to keep you on track.
Really all you need to do is stay active and put as much time as possible between each time that you eat. Hopefully minimizing that to once a day or maybe twice a day. However you manage to do that, has very little effect on the short term. As you get there, your body will adjust and you will realize things that you should or shouldn’t eat for your specific goal. If you eat late at night and have lots of breads for instance, you’ll probably be pretty hungry by midday. — and many other little facets that you will learn as you go. If you screw up one day and need o eat 3-4 times. That’s fine, as long as you get back to your schedule within a couple days.
People also aren’t really talking about the bodies natural cycles, which happen each season. At these times, your appetite will increase significantly and you shouldn’t be doing ketosis. —- the act of growth comes only one way; through expansion and contraction. In every micro and macro level. So you need to get out of it every once in awhile too. Ketosis is contraction.
Experiment with what you’re doing and don’t go too crazy on the food and you won’t gain back the pounds. Just keep your goal in mind and stay active.
Physical activity is nearly more important than ketosis.
I agree with your last point about physical activity and it’s importance as it pertains to an already pretty fit individual. A person suffering from metabolic issues and obesity probably needs the keto diet more, but exercise and it’s importance can get overlooked. The same things we love about Keto ie body composition improvements, consistent energy, mental clarity, motivation, etc are all the same benefits of physical activity. As far as cyclical keto, this is on my list of things to explore in the future, as I’m not someone using therapeutic ketosis and my metabolism is fine. I admit that I don’t know enough about it to have an honest opinion, but I’ve read about it some and will be experimenting with it for sure. I like the unique perspective.
You should be able to find recipes for pork belly without skin, just not this one because the crispy skin is part of the thrill of eating it. I’ve googled several versions of the Chinese crispy pork recipe, and the variations are interesting in how they achieve crispy skin, but the consensus seems to be boil it first, add the rub (keep it away from the skin), refrigerate over night (or longer) to dry out the skin, puncture the skin many times, roast until the crispy skin is golden brown. If its done correctly the skin should be crunchy but not hard enough to break teeth! One lady drove wooden skewers through the meat to not only hold the shape but it was also an indicator for her to tell that the meat was cooked properly. If she couldn’t remove them easily it needed more cooking time, quite clever I thought. Good luck with your search for Pork Belly with skin on!
I lost sixty pounds from going keto, and the only exercise I get is from jumping to conclusions. Dr. Phinney talks about exercise as something to do if you enjoy it, not for weight loss or for metabolic health.
As for satiety signaling, I found it kicking in once I was 6-8 weeks on a low-carb diet. Up till that point I was eating quite a bit of food at each meal, which was how I ate my high-carb diet. But what did I know? All the stuff I had read said to eat to satiety. Then, one day, I was halfway through lunch and just had to stop. It was a truly weird moment: there was food on my plate, my belly wasn’t nearly stuffed full yet, and yet I knew I was done eating. So completely different from eating carbohydrate! Then I realized that was what real satiety felt like!
I suspect that what was going on was that up till that point my body needed all the energy I could give it, and it took those weeks for the needed healing to take place and for the body to decide that setting a limit on my food intake was now desirable. I have since learned to really trust that my body knows what it is doing and stop worrying. I have days now and again when I find myself really hungry and I wonder if I am overeating, but I never seem to gain any weight at those times. So perhaps my body does know after all, lol! 
I found out what satiety was all about yesterday when I nearly demolished 1 Kg of Pork Belly (it was damn good), I could have kept going but common sense prevailed in the end and there’s still some left in the fridge. On the scales this morning and what did I find? Yup 0.8 kg up on yesterday mornings weigh-in. So I don’t think eating until you cannot eat anymore is such a great idea if your bag is also to lose weight.
I know I’m carrying that pork belly still and hopefully I’ll get rid of it soon but that just shows how quickly you can gain weight when your average daily loss is only 0.22kg. I think we need to eat more fat yes but not in such large quantities or based on whether or not you feel full. I’m a glutton so if you let me eat the whole pig, I’ll do my best to accommodate. 
Back on track this morning, only lost one day as a result of the over-eating, so its not a total train smash. Lesson learned. Reminder to self, don’t eat like a pig. 
Eating the pig is the easy part. Pork belly is an excellent way to get some fat, really soft and pretty easy to digest. That Chinese recipe was great, only I should have salted the skin more cause the skin wasn’t as crisp as it should have been. I think I’ll bake it with a layer of coarse salt next time before I crisp it up. Went well with soup the next day too!
