What is the recommended protein intake?
Sources:
and other experts on the discuss various protein intake recommendations, emphasizing its importance for muscle health and metabolic function:
-
General Recommendation:
- Aim for at least 1 gram of protein per pound of body weight per day 1.
-
For Older Adults:
- Older individuals or those over 50-60 years might require 40-50 grams of protein per meal to stimulate muscle protein synthesis effectively 2.
-
Specific Recommendations by Experts:
- highlights 1.6 grams per kilogram of body weight, which is about 0.7 grams per pound, combined with exercise for effective muscle maintenance and fat loss 3.
- For women, especially those approaching or in menopause, protein intake can be particularly crucial, and recommendations might be slightly higher, aiming for 1.5 to 1.7 grams per kilogram of lean body mass 4.
- suggests staying above 1 gram per pound of body weight to avoid complications with protein quality, type, and timing 5.
In summary, a baseline of 1 gram per pound of body weight, with adjustments for older adults and specific populations, has been recommended to support muscle health and metabolic functions.

What are techniques to reduce chronic stress reactions?
Sources:
To reduce chronic stress reactions, and other experts on the recommend various techniques:
-
Breathing Exercises:
-
Physical Practices:
-
Mindfulness and Meditation:
-
Cognitive Strategies:
- Top-down Strategies: These include raising awareness and shifting mindsets to use stress positively. Awareness and cognitive reframing can help release stress 6.
-
Environmental Changes:
- Creating a calming environment, such as a designated safe space with comforting cues like photographs, smells, or music, can help mitigate stress by providing mental relief 6.
-
Social Connection:
- Maintaining meaningful social connections is one of the most effective ways to manage long-term stress. Real-life connections provide significant stress relief compared to online interactions 7.
-
Radical Acceptance:
- Accepting situations that cannot be changed can free up mental space and reduce chronic stress. This involves regularly practicing radical acceptance to prevent overthinking and reduce mental burden 8.
Incorporating some or all of these techniques into daily routines can help manage and reduce chronic stress effectively.

What about therapeutic hypothermia?
Sources:
Therapeutic hypothermia involves cooling the body or brain to help protect against neurological damage, particularly in cases of stroke, cardiac arrest, and neonatal brain injuries.
-
Effects on Metabolism and Electrical Activity:
- Mild hypothermia (reducing brain and body temperature from 37°C to about 33°C) can protect the brain by quieting neural electrical activity and slowing metabolism 1.
- It blocks detrimental pathways such as the release of excitatory amino acids (e.g., glutamate), calcium influx, and inflammation. This multifactorial approach reduces neural damage after incidents like strokes 1.
-
Cardiac Arrest and Neonatal Hypoxia:
- Studies have shown that cooling patients between 32-34°C after cardiac arrest leads to better neurological outcomes due to reduced global ischemia (lack of blood flow to the brain) 1.
- Neonates with hypoxic-ischemic injury (lack of blood flow to the brain during birth) also benefit from cooling, as evidenced by better cognitive outcomes in follow-up studies several years later 1.
-
Long-term Health Benefits:
- Regular cold exposure, such as winter swimming, has been shown to improve insulin sensitivity, lower blood pressure, and reduce heart rate. These benefits contribute to better overall metabolic health and reduced inflammation 2.
- Improved stress response and increased comfort in cold environments are additional long-term effects of repeated cold exposure 2.
Overall, therapeutic hypothermia and regular, controlled cold exposure can significantly enhance neurological and metabolic health, particularly when initiated immediately following neurological distress events.

Does lack of oxegen to brain for possibly 18 minutes -causing extensive damage in a 37 year old female have many instances of recovery?
Sources:
Recovery from a prolonged lack of oxygen to the brain, such as 18 minutes, is challenging due to the extensive damage and high risk of severe neurological impairment. However, there are instances and methods that have shown some promise:
-
Therapeutic Hypothermia:
- Gary Steinberg explains that mild hypothermia, reducing body temperature from 37°C to 33°C, can protect the brain by blocking detrimental pathways like glutamate release, calcium influx, and inflammation. This approach has proven beneficial even after cases of global ischemia (lack of blood flow to the brain), such as cardiac arrest or strokes, leading to better neurological outcomes if applied quickly 1.
-
Cardiac Arrest and Neonatal Hypoxia:
- Studies have indicated that cooling patients between 32-34°C after cardiac arrest leads to significantly better neurological outcomes. Similarly, cooling neonates who suffer from hypoxic-ischemic injury at birth results in better cognitive outcomes years later 1.
-
Hyperbaric Oxygen Therapy (HBO):
- Though not universally endorsed, Peter Attia mentions the emerging use of hyperbaric oxygen immediately following traumatic brain injuries. While he remains skeptical about some hyperbaric claims due to poor study designs, further rigorous investigation could potentially validate its efficacy in brain recovery 2.
Recovery from such severe damage remains uncertain and challenging. However, these methods show potential, especially if applied promptly and appropriately. Each case is unique, and individual outcomes can vary widely.
