How it fits the protocol
Inside the fasting window. As a morning ritual.
01
Breakfast skip
First thing in the morning — the shake bridges the 4– 6 hour gap between waking and the eating window. Especially useful in 16:8 patients who can't push past 11am unaided.
02
Coffee replacement
Whisked into espresso it becomes the morning ritual itself. Patients who 'need their coffee' get a fasting- compatible version that respects their habit.
03
Not during 5-day FMD
The Fasting Shake is NOT included in the 5-day FMD kit — those macros are calibrated. Use the shake exclusively for daily IF days between cycles.
What's in the scoop
One 20 g scoop. 200 kcal.Fat-led, fibre-rich, protein-capped.
The shake shares its macro philosophy with the Fasting Bar — fat-forward, protein-capped — but the liquid format works better for morning routines, patients who can't tolerate solid food first thing, or anyone already attached to a hot drink ritual.
PER 2 CAPS
5 g
MCT powder
Coconut-derived C8/C10
Medium-chain triglycerides convert directly to ketones in the liver without spiking insulin. The active ingredient in the shake — what makes it sustain a fast rather than break it.
PER 2 CAPS
—
Cocoa or vanilla flavour
Natural sources only
Cocoa (Dark Chocolate, Coffee & Cocoa) or Madagascar vanilla. No artificial flavourings, no sucralose, no stevia. The shake tastes like the food it's named after.
PER 2 CAPS
4 g
Inulin + acacia fibre
Chicory root + acacia
Soluble fibres smooth the small glucose response and feed the post-FMD microbiome. Same family of prebiotics used in L-Biome — the synergy is intentional.
PER 2 CAPS
3 g
3 g plant protein
Pea protein isolate
Capped at 3 g for exactly the same reason as the Fasting Bar — high enough to round the texture, low enough to keep IGF-1 / mTOR pathways quiet during the fast.
Macro split · per 20 g scoop
60% fat. 8% carbs.
