zigzag diet routines

hey folkes

Im sure a lot of you know the so called abcd diet which stands for a 14 day calorie deficit followed by a similir surplus

there are also other similar routines which suggest a shorter period of 3 days cutting 1/day maintenance/bulking - others say such periods maybe to short to be effective and let the body adapt to it in the way it should

have any of you experiences with such approches?
I've tried them all. In addition, I've put in a lot of years looking into the physiology behind them.

In the end, there is very little if any support for them.

A better approach is to use periods of normalization, rather than drastic jumps from one end of the specrum to the other. Short periods of refeeding such as with a CKD (e.g. UD 2.0) are a slightly different situation and don't pose the same problems and a diet strategy such as ABCD, etc.
but ckd has kind of drastic jumps in it even if the refeeds are used to refill glucogen storages?

so you say that drastic jumpes should be avoided, but a switch between calori-deficit and maintenance may work

but what about the periodlengths? does it really matther for your body if the periods are shorter or longer - can it switch that quickly?
