The GAPS Spectrum

The GAPS Spectrum

The GAPS (Gut and Psychology Syndrome) protocol is not a one-size-fits-all model. Recognizing that each person has different needs, sensitivities, and conditions, Dr. Natasha Campbell-McBride developed 6 variations of the protocol, forming a spectrum that ranges from the most restrictive to the most flexible.

The 6 Variations

1. Introduction GAPS

The most structured and gradual version, divided into 6 progressive phases. It is the most well-known and documented version of the protocol.

Who it is for:

• People with moderate digestive problems
• Autism, ADHD, depression, anxiety
• Food allergies and intolerances
• Eczema, psoriasis, and other skin conditions
• People who want to follow the protocol in a complete and systematic way

2. Full GAPS

For people with less severe symptoms who can skip the introductory phases and go directly to the full GAPS diet.

Who it is for:

• Severe constipation (introductory phases may worsen it)
• People who already have a good dietary foundation
• Those seeking health maintenance rather than intensive treatment

3. No-Plant GAPS

Completely eliminates all vegetables and plant-based foods, focusing exclusively on animal-sourced foods.

Who it is for:

• Severe Crohn's disease
• Ulcerative colitis
• Severe reactions to fiber and vegetables
• People who cannot tolerate any plant food

4. No-Dairy GAPS

Eliminates all dairy, including fermented dairy.

Who it is for:

• Proven casein allergy
• Severe dairy intolerance that persists even with fermented products
• Severe autoimmune conditions

5. Ketogenic GAPS

Combines GAPS principles with ketogenic macronutrient ratios (high fat, very low carbohydrate).

Who it is for:

• Epilepsy
• Neurological conditions (Alzheimer's, Parkinson's)
• Cancer (as complementary therapy)
• Severe insulin resistance

6. More-Plant GAPS

A version with greater emphasis on vegetables and less on animal proteins, while maintaining the protocol's principles.

Who it is for:

• People with good digestion who tolerate vegetables well
• Maintenance phase after gut healing
• Those who prefer a diet with more plant variety

How to Choose

The choice of variation depends on:

• Severity of symptoms: more severe symptoms generally require more restrictive versions
• Type of condition: neurological conditions may benefit more from the ketogenic version
• Individual tolerance: observing which foods cause reactions
• Professional guidance: a certified GAPS practitioner can help with the choice

Flexibility Is Key

The GAPS spectrum is not rigid. A person may start on one variation and migrate to another as their health improves or as they discover their specific needs. The protocol is a tool, and like any tool, it should be adapted to the job that needs to be done.

There is no perfect diet for everyone. The GAPS spectrum recognizes this individuality and offers options so that each person can find the path that works for them.
