Meal Planning by PHS in Human Design: Eat According to Your Design

What Is PHS and Why Does It Matter?

Primary Health System (PHS) is part of your bodygraph's Variable that determines the ideal way of eating for your body. PHS doesn't tell you WHAT to eat (that's nutrition science), but HOW to eat — in what environment, at what time, in what state.

There are 6 PHS types (determinations), each with a left (active) and right (passive) tonality.

6 PHS Determinations

1. Appetite

Your body knows what it needs:

• Left: eat what you want, when you want — your appetite is correct
• Right: wait until appetite comes naturally; don't eat "on schedule"
• Practice: keep an appetite diary; notice what your body responds to

2. Taste

Taste buds are your main guide:

• Left: eat what tastes best right now
• Right: let tastes come to you; don't actively seek them
• Practice: eat slowly; focus on the taste of each bite

3. Thirst

Liquids play a key role:

• Left: drink plenty of liquid with meals
• Right: liquid foods — soups, smoothies, juices — are your ideal
• Practice: experiment with liquid-to-solid food ratios

4. Touch

Food texture matters:

• Left: choose food by texture — crunchy, soft, creamy
• Right: pay attention to temperature — hot or cold?
• Practice: notice which texture brings the most satisfaction

5. Sound

Acoustic environment during meals is critical:

• Left: eat with music, conversation, sounds — stimulating background
• Right: eat in silence or with very soft sounds
• Practice: compare how food digests in silence vs. with music

6. Light

Lighting during meals affects digestion:

• Left: bright natural lighting during meals
• Right: dim or indirect lighting
• Practice: try breakfast by the window vs. in a dark room

PHS and Type

• Generator — eat when there's sacral response to food, not "because it's time"
• Projector — smaller portions but higher quality; don't eat "socially"
• Manifestor — eat by impulse, not by schedule
• Reflector — experiment with different routines throughout the month

General Principles

• Eat alone or with the right people — others' auras affect digestion
• Avoid eating under stress — stress = poor digestion
• Observe for 3 months — your body needs time to adapt to the new regime

Practical Steps

1. Calculate your bodygraph — identify your PHS determination
2. For one week, record HOW you eat (environment, time, company)
3. Implement one recommendation from your determination
4. Observe digestion, energy, and well-being
