“Another study suggests that intermittent fasting combined with exercise training increased serum ketone levels, increased the number of mitochondria in muscle cells, and improved endurance. In this clip, Dr. Mark Mattson describes how fasting and exercise work together to promote brain health.”

“As a starting point, Dr. Attia suggests people consume just enough protein to maintain and grow muscle mass. The oral glucose tolerance test, which monitors glucose and insulin levels, can be used to determine carbohydrate limits.”

“Future research will need to compare different collagen types, doses, and delivery formats, and determine whether these changes translate into meaningful improvements in daily function or long-term health. In this clip, Dr. Luc van Loon discusses collagen's effects on muscle, cartilage, peptide absorption, and potential skin and joint benefits.”

“In athletes, skeletal muscle is constantly being remodeled and may serve as a source of glucogenic amino acids. In this clip, Dr. Dominic D'Agostino describes how gluconeogenesis fills an important role during ketosis to maintain a basal level of glucose.”

“Participants completed one hour of cycling at 65 percent of their maximum aerobic capacity on one day and rested the next day. The researchers collected biopsies from the participants' thigh muscle after they had rested and 15 minutes after they exercised.”

“Notably, a small group of endurance athletes who developed an overtraining syndrome involving muscle damage and persistent fatigue showed shorter muscle telomeres, highlighting the importance of sufficient recovery.”

“Those repeated interruptions may keep muscles more responsive to insulin throughout the day, and potentially even into the next, in a way that one short moderate-intensity exercise session cannot reproduce.”

“Exercise is essential in preventing age-related physical and mental decline. Sarcopenia, the loss of skeletal muscle tissue with age, is one of the most important causes of functional decline and loss of independence in older adults.”

“Exercise promotes the release of insulin-like growth factor-1 and its downstream targets, growth hormone and brain-derived neurotrophic factor, to drive muscle and neuron growth. Sauna use increases these factors, too, and when used post-exercise, may have a synergistic effect to improve cardiovascular, musculoskeletal, and neurological health.”

“For example, exercise increases muscle growth. However, this growth only occurs following a period of rest, during which new mitochondria are produced. Switching between challenge and rest is critical for the body to reap the benefits of mild stress such as fasting.”
