“One of the mechanisms behind the beneficial effects of exercise is its ability to induce autophagy in skeletal muscle and, potentially, other organs. In this clip, Dr. Guido Kroemer describes the anti-diabetes and anti-obesity effects of exercise-induced autophagy.”

“The physical activity guidelines and estimates on how much activity we need are heavily based on self-reported activity, which is useful but imperfect: people remember going for a run, but they forget the short, intense bursts in daily life like sprinting up stairs, chasing kids, and running to catch a bus.”

“Wearable-device research in more than 25,000 adults who reported no structured exercise linked about three one- to two-minute vigorous bouts per day with substantially lower all-cause, cardiovascular, and cancer mortality.”

“Exercise can improve blood pressure, insulin sensitivity, triglycerides, and fitness, but someone with high ApoB or LDL may still need targeted diet changes and clinician-guided lipid-lowering treatment. Mood is another major benefit.”

“When produced during exercise (especially high intensity workouts like cycling, which shifts metabolism toward glycolysis to more quickly meet the high energetic demands), lactate switches on more than 600 genes involved in muscle adaptation, stimulates mitochondrial biogenesis – the process of making new mitochondria – and promotes protein synthesis, which is essential for muscle growth.”

“The body has elegant mechanisms that allow it to utilize non-carbohydrate substrates to generate glucose. Gluconeogenesis is a metabolic pathway in which the liver produces glucose from non-carbohydrate substrates including glucogenic amino acids (from protein) and glycerol (from lipids).”

“In a randomized crossover study of 18 young men with overweight or obesity, ten three-minute walking or squat breaks spaced every 45 minutes across 8.5 hours lowered post-meal glucose exposure more than uninterrupted sitting or one continuous 30-minute walk.”

“In more than 25,000 adults who reported no leisure-time exercise, a median of three one- or two-minute bouts per day was associated with 38 to 40 percent lower all-cause and cancer mortality and 48 to 49 percent lower cardiovascular mortality compared with no VILPA.”

“Standard metabolic screening still relies on validated laboratory measures such as A1c, fasting plasma glucose, or a two-hour glucose value after a standardized oral glucose tolerance test. Skin changes or unexpected glucose patterns can therefore be useful prompts for a clinical evaluation.”

“In eight young men, seven days of 1,000 milligrams of NR per day changed selected muscle NAD metabolites but did not alter substrate use, mitochondrial respiration, or signaling involved in adaptation to one hour of endurance exercise.”
