Bro, I don't agree with any of that!
It's simple, but difficult in it's simplicity. You are told to avoid low-GI carbs, so I find myself avoiding things like lasagne or risotos because of the pasta and rice respectively - you can't, or rather you shouldn't, eat them even on your backload.
Firstly, white rice is a fantastic carb source for a backload. Pasta less so, but...
Secondly, it doesn't matter! If you fancy having a pasta meal, a backload is the PERFECT time for it. Is it optimal? No, but you're talking about a couple of percent difference to your daily outcome.
You should be trying to make this diet work for you, rather than restricting what you can have in your "cheat" portion of the day. Don't have brown rice/pasta, but don't worry about everything else. Even bread is ok.
This means you start eating things like 'pack of sausages' with maybe the additional side of broccoli. 'Cooked meals' and recipies have somewhat gone out of the window. I think that's a bit crap, but it's what it encourages you to do. It's also quite hard not to become obsessive about it for fear of putting yourself through the nauseating preparation stage again.
C'mon man! There are thousands of meals you can cook. All you've done is default to the meals you normally turn to when you're cutting.
Low carb:
- salad with meat <---- that should be enough variety there anyway, most dressings are low carb too
- meaty soup
- stew
- meat and veg (this is where you live, but what about the other veg and meats!)
- chicken with avocado with olive oil and a splash of lemon
- tuna mayo
High carb:
- curry with loads of rice
- ANYTHING with loads of rice
- pasta meals
- anything high carb you've been craving
...in fact, this is too easy for me to carry on listing
You are making this WAY too difficult. Tbh you're massively setting yourself up to get sick of the diet.
It would be INCREDIBLY hard to mess with your system enough to need to do the prep phase again. We're talking eating carbs all day for a week, probably more.
Other massive negative - my concentration still doesn't seem to be operating at 100%, although I've taken measures to limit this and I'm coping better. Really it's not surprising, you are probably going to function mentally better with some carbs in you.
As I've said to you, this is false. If you're completely carb depleted, as in the prep phase, then maybe. But your body should be coping because you should be eating enough fats.
Other potential negative - not sure on the long term effects with regards to the pancreas / diebetes. I just can't imagine it being good for you in the long term considering the stress you are putting on your body, even if it is intermittant.
CBL is going to be better for your pancreas than most other things. Why? You're dealing with 1 insulin spike per day. Yes, it's a big spike, but compare this to the bad scenario of lots of spikes throughout the day, and not letting your levels return to baseline ever.
But the results speak for itself. The fat has flown off, not sure if I've gained any strength but that's not my goal. I have never had such rapid fat loss before.
But yes, it is extremely effective.
You've already done the hard part (and it is very hard!) and are seeing good results, so now you need to be minimising difficult bits.
