Summary
Registered nutritional therapist Dr. Sarah Bayliss joins coach Allan to discuss her book, Do Nourish: How to Eat for Resilience. Bayliss runs a private practice specializing in metabolic health, energy management, and stress resilience, working with clients one to one and designing group programs and workshops. She started her career in marketing in London and, after coming close to burnout, moved out of the city to restart her career in health.
Bayliss frames nutrition as one of the biggest inputs into our resilience, using the analogy of a bucket that both fills with life’s demands and needs to be replenished so we can cope with what life throws at us. She argues that food is information, sending signals that tell the body it is safe and nourished or that it is not, and encourages people to eat more intentionally rather than treating food as mere fuel.
The conversation covers eight modern health challenges, the five pillars of nourishment, and a six-week implementation process for adjusting one pillar at a time. Bayliss also makes the case for keeping a food diary and taking time to cook as ways to take back control of your health.

Key Takeaways
- Resilience is not about working harder or longer hours; it is about being able to cope with and respond positively to what life throws at you, and nutrition is one of the biggest inputs that builds that capacity.
- Food is information: every time you eat, the food either builds your health or takes it away, and metabolism is a system constantly assessing your environment (food, sleep, movement, light) to keep you safe.
- Modern health is undermined by challenges including changed eating habits, the rise of ultra-processed foods, declining food quality from depleted soils and pesticides, being overfed and undernourished, too little time outdoors and natural light, and too much blue light at night.
- The five pillars of nourishment, in order of priority, are protein, healthy fats, non-starchy vegetables (fiber), polyphenols, and complex carbohydrates; the goal is to include these in every meal.
- Protein is a structural, repair macronutrient rather than a fuel; it builds the brain, immune system, and enzymes, helps stabilize hunger and blood sugar, and is commonly under-consumed.
- There is a food hierarchy: prioritize the essential nutrients the body cannot make (essential amino acids in protein, omega-3 fatty acids in fats), get fiber and polyphenols in, and treat complex carbohydrates as the least essential and last part of the plate, since carbs are the food people most often overeat.
- Keeping a food diary brings attention to autopilot eating behaviors and reveals insights (such as how much sugar you actually consume), enabling small, realistic tweaks rather than judgment.
- Taking time to cook, even just fifteen to twenty minutes, and batch cooking (cook once to eat twice) lets you take back control of your health instead of putting it in someone else’s hands, and can be made an activity of joy.
- Bookmark your day: get morning light through your eyes to set your circadian rhythm and eat a good breakfast, then wind down in darkness away from screens to sleep well, and the middle of the day tends to work itself out.
