The model represents health as a pizza whose layers depend on one another. The crust is digestion and hydration: nutrients cannot support the body if they are not broken down, absorbed, and transported. The sauce is better nutrition, evaluated through four pillars—quantity, quality, timing, and balance—rather than a single diet rule. The cheese is lifestyle, including stress, breathing, joy, movement, and recovery. Optional medications, supplements, and targeted tactics sit above those layers like toppings. The mechanism is sequencing: improve the load-bearing systems first, then personalize the other layers and add tools only where they solve an identified need. A good topping cannot rescue a poor crust, sauce, and cheese.
Origin
Ashley Koff uses the analogy of a pizza to explain the layered system in her book Your Best Shot: crust, sauce, cheese, then optional toppings.
Core principles
- 01Build on digestion and hydration first
- 02Assess nutrition by quantity, quality, timing, and balance
- 03Match lifestyle choices to the body's needs
- 04Treat medications and supplements as optional toppings, not foundations
How to run it
- 1
Repair the crust
Assess whether digestion can break food down and whether hydration can move water and nutrients where needed. Address obvious digestive and hydration barriers first.
Pro tip Look beyond water intake to whether the body retains and uses it.
Watch out Healthy food still fails if nutrients are not absorbed.
- 2
Balance the sauce
Review nutrition through quantity, quality, timing, and balance. Personalize eating windows and pit stops rather than imposing a universal schedule.
Pro tip Test whether earlier eating and regular fueling improve function.
- 3
Choose the cheese
Match movement, recovery, stress regulation, breathing, and joy to the person's current state. More exertion is not always the missing input.
Pro tip Distinguish a need for stimulation from a need for recovery.
Watch out A fixed exercise target can hide an otherwise sedentary day.
- 4
Add only useful toppings
Use medications, supplements, tests, or devices when they address a defined gap and can be evaluated. Keep them optional and subordinate to the foundation.
Watch out Do not let a tool become a pass for ignoring the other layers.
In the wild
A person using a GLP-1 also assesses digestion, maintains appropriate nutrition, supports muscle, and regulates stress rather than relying on appetite suppression alone.
→ The medication functions as one tool in a broader weight-health plan instead of the whole plan.
Someone shifts a noon-to-8 p.m. eating window earlier, adds regular daytime fueling, and observes energy, hunger, and digestion.
→ Meal timing becomes personalized to body response rather than dictated by a fasting label.
Common mistakes
Starting with toppings
Medication, supplements, or isolated hacks cannot compensate for weak digestion, hydration, nutrition, and lifestyle foundations.
Using one-size-fits-all timing
A standard eating window may conflict with an individual's energy and fueling needs.
Equating exercise with movement
One scheduled workout does not replace regular movement or the recovery needed after hard exertion.
Is it for you?
Best for
People building a personalized weight-health plan with or without GLP-1 medication.
Not ideal for
Anyone seeking a universal diet prescription or a single intervention that bypasses assessment.
From the transcript
“So, I use the analogy of making a pizza. So, everybody gets a pizza. There's a crust, there's sauce, there's cheese, and there's toppings.”
“the reality is the crust is digestion and hydration.”
“The cheese are your lifestyle choices. Stress, breathing, joy, um you know, we want to make sure that we're moving our bodies.”
