Summary
On episode 287 of 40+ Fitness, Coach Allan sits down with Ori Hofmekler, author of The Seven Principles of Stress, whose military background in Israel drove his interest in the science of stress and resilience.
Ori’s central point is that stress isn’t the enemy: the right kind of intermittent stress (fasting, exercise, even certain foods) trains the body to become more resilient, while chronic stress and excess energy intake do the opposite.
The conversation covers his seven principles of stress, why synthetic antioxidant supplements can work against you, and why elite endurance athletes chasing performance often don’t live as long as people who train for resilience.

Key Takeaways
- Low-level stress exposure builds resilience to high-level stress. This is the basic hormesis principle behind training of any kind, from lifting weights to vaccination. You have to build tolerance gradually rather than jumping to a level your body isn’t ready for.
- Maximum resiliency comes from combining nutritional and physical stress. Exercising while fasted maximizes the adaptive benefit compared to doing either one alone.
- Energy deficit, not surplus, drives adaptation. Ori’s fourth principle: it’s the depletion of energy, not an abundance of it, that triggers the body to improve. Excess energy intake has been shown to shorten lifespan across species, while energy deficit can extend it.
- Stress has to be intermittent, never chronic, to help you. Nothing in the body is built to tolerate a constant stressor. If a stress can’t be made intermittent, Ori says it should be avoided.
- Synthetic antioxidant supplements can work against you. Exercise and mild oxidative stress trigger the body to produce its own antioxidant enzymes (glutathione peroxidase, catalase, SOD). High-dose synthetic antioxidant supplements can shut down that natural defense system instead of supporting it.
- Aging is more stress-related than age-related. Ori’s three principles to slow aging: eat less and introduce stress-mimicking nutrients found in whole foods; avoid substances (starting with sugar in all its forms) that blunt the stress-response system; and exercise regularly, ideally while fasted.
- Chasing athletic performance is not the same as building a body built to last. Ori points to data showing competitive endurance athletes often don’t live longer than sedentary people, because training purely to score overextends the stress threshold instead of building resilience.
- Fat adaptation takes about four consecutive days. Shifting from carbohydrate to fat as a primary fuel source takes roughly four days of consistent low-carb eating to maximize, according to Ori. Bailing back to carbs after one hard day means the body never gets the chance to adapt.
“It is the energy deficit that you cause on your body that trigger your body to adapt and improve.”
