The Six Pillars of Health
Dr. Kyle Gillett's foundational framework: six lifestyle pillars, diet, exercise, sleep, stress, sunlight and spirit, that he argues are more powerful than any medication or supplement, with diet and exercise leading.
Before any hormone or supplement talk, Kyle Gillett (a physician dual board-certified in family and obesity medicine) anchors health on six lifestyle pillars: diet, exercise, sleep, stress optimization, sunlight, and spirit. He is clear that diet and exercise are the two most powerful, and that these foundations outperform any pill. His other key idea is the law of diminishing returns: a little, done consistently over years, beats a lot done briefly then abandoned. It is a deliberately unglamorous, foundations-first framework, with annual bloodwork to track how you are actually doing.
Why it works▼
Eat a whole-food diet that fits you
Diet is one of the two most powerful pillars for hormones and health.
Train, with resistance work as a priority
Resistance training is especially powerful for hormone and metabolic health.
Protect consistent, quality sleep
Sleep underpins hormones, recovery and mitochondrial function.
Optimise (not eliminate) stress
Chronic stress disrupts hormones and wellbeing.
Get outdoors and natural light
Light and time outdoors support sleep, mood and hormones.
Cultivate purpose and meaning
Gillett considers purpose and meaning integral to whole-person health.
Track bloodwork; favour consistency
Tracking guides adjustments, and consistency is what compounds.
- Anyone wanting a foundations-first framework
- People tempted to chase supplements before basics
- Those optimising hormones naturally
- Anyone who values consistency over intensity
- These are general lifestyle foundations, not a substitute for medical care; bloodwork should be interpreted with a clinician, not self-diagnosed
- Individualise it: not everyone needs caloric restriction, and the right diet and training vary by person
- The 'spirit' pillar is framed broadly as purpose and meaning; take what fits your own life and beliefs
- Educational only, not medical advice
