I am 40 years old, 5'11, fairly strong but also carrying a lot of fat. What are the most impactful things I can do in regards to sleep, supplements, activities, etc. to increase testosterone, decrease cortisol, and be healthier to lose weight and get in the best shape of my life


To improve testosterone levels, decrease cortisol, lose weight, and get into the best shape, consider the following recommendations from the Huberman Lab:

  1. Optimize Sleep: Sleep is a foundational factor that indirectly affects testosterone levels. Ensure you get adequate, quality sleep 1.

  2. Manage Stress: Chronic stress should be kept to a minimum as it indirectly affects hormones 1.

  3. Exercise: Engage in resistance training and balance it with caloric restriction to address weight loss and hormone health. Long training sessions can be counterproductive, so train hard but not too long 2.

  4. Diet: Consistently adhere to healthy eating habits and consider caloric restriction to manage weight effectively 2.

  5. Supplements:

    • Tongat Ali: Taking 400 milligrams of Tongat Ali per day may reduce sex hormone binding globulin and increase testosterone levels. It tends to work better after continuous use over a few months. It should be taken early in the day due to its stimulant effect 3.

      Optimizing Testosterone

      Andrew Huberman shares insights on optimizing testosterone levels, including the use of Tongat ali and Phdogia agrestis supplements. He also discusses the importance of sleep, managing stress, and effective training methods.

    • Phdogia Agrestis: Acts as a luteinizing hormone mimic, stimulating the testes to produce more testosterone 3.
  6. Lifestyle Interventions:

    • Diet and exercise are crucial, with resistance training being particularly beneficial for hormone health.
    • Manage stress, which plays a role in cortisol levels.
    • Prioritize sleep and establish a consistent sleep pattern.
    • Get regular sunlight exposure for overall well-being.
    • Maintain spiritual health, which can deeply influence your mental and physical state.

Finally, while incorporating supplements, ensure that any significant changes in lifestyle or supplement use are discussed with a healthcare professional to manage any potential impacts 4.

To optimize for the long-term, uncover and address the root causes of any health challenges, rather than relying solely on supplements or quick fixes. Implement the aforementioned adjustments gradually to establish effective and sustainable health habits.
