This is the most important week we have worked towards. This is the central "pivot" within the 17-week cycle. During this week maximum autophagy will be achieved. Here we intensify restrictions to its fullest potentiall by applying a maximum 7 day water fast, combined with electrolytes and vitamins to support the body in this cleansing mission. The body will stabilize, balance out any excess, get into deep microbiome cleanse and cellular cleanse. 7 days of water, teas and coffee while keeping activities moderately high.

This week happens after a previous 8 weeks of restrictive preparation. The change from week 8 into this week 9 should feel quite smooth. The body is already in ketosis and the microbiome already in a recompositioning process.

Microbiome: as now close to zero calorie enter the previously favored bacteria will have a head start  in survival compared to the previously starved bacteria. The point is to flush out as much as possible of 'bad' bacteria.

Body composition: You will experience a drop of several kg during this week. Very important to understand several kg are just lost water and poop. Fat and other tissue is going to be somewhere between 2-4kg (the rest is temporary weight loss). The body will use as much fat as it can. And the exercising (VILPAs mostly, as well as the 1 weight lifting) will signal to the body to preserve as much healthy tissue as possible, so the body will focus on getting rid of old tissue in a targeted way.
