Creator perspective · FuelDr. Thompson explains that biopsies must be very targeted to get the tissue of interest, because even sampling an area that looks like a tumor may not capture cancer cells — but once tissue is obtained, stains can reveal genetic predisposition and whether the tissue will respond to one drug over another.

Creator perspective · FuelWhen Intuitive Surgical robots came out, they democratized the field — taking mediocre surgeons and making them excellent while excellent surgeons stayed excellent. A truly exceptional surgeon is probably better without the robot, and the robot may even make them worse.

Creator perspective · FuelDr. Thompson explains mechanisms behind processed-food overeating: people eating food in a wrapper are inclined to eat more of it; processed foods are easier to digest, produce bigger glucose spikes, and have a lower thermogenic effect of food; and they are probably not doing great for your microbiome because there's less fiber in them.
The microbiome claim is hedged ('probably').

Report · FuelDr. Sara Gottfried states that women having the most perimenopause/menopause symptoms, such as hot flashes, night sweats, and difficulty sleeping, are the ones with the most significant cerebral hypometabolism.

Creator perspective · FuelDr. Sara Gottfried notes that oral contraceptives and other forms of contraception can mask what your normal menstrual cycle is, leaving you with no idea what the normal cycle is. She also observes that menstrual cycles are often not regular in terms of duration when the cycle first sets in for many women.

Report · FuelDr. Sara Gottfried reports that oral contraceptives make the hypothalamic pituitary adrenal axis more rigid, reducing the ability to adapt cortisol production, and can also affect thyroid function.

Report · FuelDr. Sara Gottfried recommends a menu of stress-relief tools: holotropic breathwork, yoga (she became a certified yoga teacher in her 30s and finds it very effective for many people), meditation (which she says has a strong scientific basis), and connection-oriented practices including sex, orgasm, connection, and feeling heard, seen, and loved.

Creator perspective · FuelLactate has historically been thought of as a waste product produced when cells can't burn fuel due to lack of oxygen — the cause of the exercise 'burn' — but Rutter describes it as one of the mediators of the cell's building decision in resource allocation.

Creator perspective · FuelMuch research energy over the last 10–15 years has gone into blocking cancer cells' resource allocation toward building new cells, but this is difficult because resistance develops easily — a cancer cell can mutate and rewire its metabolism to build the same thing a different way.

Report · FuelGlucose is the preferred fuel source for most every cell. Neurons are particularly fond of consuming glucose to make their ATP, which puts a stringent demand on the body to keep glucose available; they are very adept at taking in glucose, burning it, and making ATP from it. The ability of neurons to consume fatty acids is limited — traditionally thought to be close to zero, though that is being questioned. The brain can thrive on ketones, so carbohydrates are not strictly essential.
The claim that carbohydrates are not essential is stated with low confidence; the neuronal fatty acid question is explicitly open

Creator perspective · FuelMPC is the first step toward one destination of pyruvate: it pulls pyruvate into the mitochondria so it gets used there rather than in the cytosol. This framing has driven much of Rutter's subsequent work on the implications of MPC function.

Report · FuelIf glucose is too low, you die within minutes — not seconds — most importantly because the brain requires some glucose to keep functioning. High blood glucose is also damaging, but that damage occurs over years; a person can live with diabetes for years before succumbing to it.

Anecdote · FuelDr. Thompson describes that a couple of years into practice the problem persisted: FNAs (fine needle aspirations) often yielded no answer. Patients wouldn't want major surgery to have their pancreas removed without an answer, then their cancer worsened, and by the time a diagnosis was made it was too late to treat and help them.

Creator perspective · FuelDr. Chris Thompson explains that testing metabolic flexibility is harder because you have to do a breath study looking at gas exchange. The respiratory exchange ratio is a volume of carbon dioxide divided by a volume of oxygen, based on the first law of thermodynamics. Carbohydrates have an equal number of carbon and oxygen, so they don't require much oxygen to burn, while burning fat requires more oxygen. A ratio of about 0.7 means you're burning fats; a ratio of 1 means you're burning carbs, with intermediate values in between. Athletes use this testing to optimize performance.

Report · FuelDr. Thompson describes Sheila Sherlock's London lab — famous for founding the field of hepatology — where subjects were given a set amount of glucose intravenously and insulin was measured, then the same amount orally produced much more insulin; this was coined the incretin effect. The researchers didn't know if taste was involved but attributed the effect to incretin from the duodenum based on the 1930s study.
