I disagree wholeheartedly. Carb ups are not carb ups but an excuse to eat carbs .. the end result is what matters. Being in shape.
Whe you stay on zero carbs a few weeks the body starts working like a machine if you know your nutrition. Burns fat efficiently and it's a powerful detoxifier.
Carbing up overstimulates the pancreas, fucks you up a for a little while, confuses the body etc... you need the same thing day in and day out then the body regulates intself as far as fat burning is concerned.
Dude you talk down to people a lot. And most of the time they deserve it, but now you're talking out of your ass.
I don't know how they do things in Romania, but here in the American scientific community you better be able to back up the things you claim. There is tons of evidence out there that going on keto for too long and you will find yourself eating 1,500 cal or less per day and still not making progress this is totally fucked.
So very well educated people studied this and found that too long on keto and your body shuts down important hormones namely leptin, insulin, and ghrelin thus halting fat loss. Way too complex for me to explain.
Read "The Carbnite Solution" by Kiefer. This man knows the actual science behind what he claims and can back it up..Unlike you.
Dude honestly you got lean one time, and I attribute that mostly to drugs and a low cal diet...You weren't anywhere near shredded stage shape either..So please stop acting like you're some fucking expert guru on all things because you got to 6% bodyfat once in your skinny-fat Romanian lifetime...There are people who eat 500g of carbs a day and stay leaner than you, at your leanest, year round...
