The energy balance model and carbohydrate-insulin model of obesity are not mutually exclusive — a 2024 Nature Metabolism perspective paper co-authored by adversaries Kevin Hall and David Ludwig found large zones of agreement, with the core unresolved question being whether overeating precedes fat deposition or the reverse.

Where fat is stored matters far more than total fat mass: 5 kg of visceral or ectopic fat in the liver, muscle, or pancreas carries higher metabolic risk than 50 kg of subcutaneous peripheral fat — making BMI and total body weight poor proxies for disease risk.
3
For muscle building or preservation, dietary protein should be at least 1.6 g/kg body weight and there is no demonstrated benefit above 2.2 g/kg; during active calorie restriction the percentage of calories from protein must rise sharply (often 20–30%+) to spare lean mass.

GLP-1 and dual GIP/GLP-1 agonists can achieve bariatric-surgery-level weight loss but require indefinite use — stopping returns patients to their prior weight trajectory — and real-world compliance is poor even without cost barriers.

Protein intake for muscle hypertrophy: 1.6 g/kg floor, 2.2 g/kg ceiling
WhatTarget dietary protein between 1.6 and 2.2 grams per kilogram of body weight per day when the goal is building or maintaining muscle mass.
WhenDaily, distributed across meals. The 2.2 g/kg upper bound represents the saturation point for muscle protein synthesis — calories above this threshold are oxidized or stored as fat.
Dose1.6 g/kg minimum for hypertrophy stimulus; 2.2–2.3 g/kg ceiling. No added benefit has been demonstrated above 2.2 g/kg in studies measuring muscle protein synthesis across different feeding and exercise conditions.
For whomAnyone aiming to build muscle mass. For older adults with anabolic resistance, the effective dose may shift toward the upper end to achieve the same synthesis response.
WhyMuscle protein synthesis responds linearly to protein intake up to a plateau; flooding beyond the ceiling does not further stimulate synthesis and adds unnecessary caloric load. Both Magkos and Lyon converge on this range despite Magkos eating only ~1.3 g/kg personally — because he accounts for his high total caloric intake from extreme endurance training.
CaveatsNo downside to protein intakes up to this range in healthy individuals without kidney disease. The percentage of calories from protein must be interpreted alongside total caloric intake — Magkos at 10% protein but 3,500 kcal/day achieves ~90 g protein, which is adequate for his 70 kg body weight at maintenance.
Lyon notes that expressing protein as a percent of calories can be misleading: Magkos at 10% protein on 3,500 kcal/day (~90 g, ~1.3 g/kg) meets needs only because of his high total intake and endurance-heavy activity. Someone eating 1,500 kcal/day at the same percentage would be severely protein-deficient. The practical prescription is always in absolute grams per kg, not percent of calories.
Mechanism
Insulin halts muscle protein breakdown after resistance exercise. Dietary amino acids then drive net protein synthesis positive. The combination of halted breakdown plus elevated synthesis creates the net gain. Aging blunts the anabolic signaling at any given protein dose — hence the recommendation to lean toward the higher end of the range in older adults.
I think that you should go upper of 1.6 but definitely no I don't think there's any need for more than 2.2 2.3 I think that that's where it you saturate the system.
Protein percentage during calorie restriction must increase sharply
WhatWhen actively restricting calories for weight loss, increase protein's share of total calories to 20–30% or higher, rather than maintaining the same absolute protein intake you had at maintenance calories.
WhenDuring any active calorie-restriction phase for fat loss.
DoseVLCD (very-low-calorie diet) commercial products now target ~50% of calories from protein at 800 kcal/day — the evidence rationale behind protein-sparing modified fasts (PSMF).
For whomAnyone pursuing weight loss through calorie restriction, particularly older adults, those using GLP-1 agonists, and anyone concerned about lean mass preservation.
WhyAs total caloric intake falls, the competing energy demands of carbohydrate and fat oxidation compete with protein for caloric 'space.' Maintaining the same gram target while eating fewer calories automatically raises protein's percentage; failing to do so risks using dietary protein for energy rather than lean mass preservation.
CaveatsThis is a percentage argument not an absolute-more argument: someone eating 3,500 kcal/day needs 10% protein; someone eating 1,000 kcal/day needs 20–30% protein to achieve the same absolute gram target.
The protein-sparing modified fast concept dates back to the 1970s and is the theoretical basis for modern VLCD products. Magkos notes that current commercial VLCD products (e.g., those available in Europe) are already formulated at ~50% protein from a 800 kcal/day base precisely for this reason. Lyon adds a clinical caveat: one-meal-a-day approaches, whatever their population-level neutrality, are contraindicated for muscle-protective goals in older adults and anyone in active resistance training.
The person who is active in calorie restriction and eating 1,000 calories a day to lose weight the percent protein should be 20 or 30.
Also said
“All the now commercial VLCD products know the very low energy diet products like... all these now are about 50% protein right because you eat only 800 calories a day then protein is the most important nutrient to match.”— Real-world application: commercial medical weight-management products have already operationalized this principle.
Resistance training prioritized over endurance for aging and functional capacity
WhatFor adults whose primary goal is healthy aging and functional independence, weight lifting and resistance training should be the primary exercise modality — more important than steady-state cardio.
WhenLifelong, with increasing priority from middle age onward.
DoseMagkos personally lifts 2–3 days per week alongside high endurance volume. He advocates that the aging population prioritize lifting even at the expense of cardio volume if time is limited.
For whomAll adults, but highest priority for those 50+ or anyone motivated primarily by longevity and independence rather than cardiovascular fitness.
WhyFunctional independence — the ability to perform activities of daily life independently in old age — is driven by muscle mass, strength, and power, which are primarily preserved through resistance training. Endurance burns more calories acutely but has less functional-capacity return for the typical aging adult.
CaveatsEndurance exercise is not irrelevant — it is essential for VO2max and cardiovascular health. But if forced to choose, resistance training has the stronger claim on functional aging. HIIT is an efficient way to hit both targets when time is scarce.
Magkos uses the framing 'functional independence' deliberately: the goal is not cosmetic or even metabolic, but the ability to age with autonomy. He notes that from a pure caloric-burn perspective, endurance dominates — running an hour burns ~500 calories (roughly a slice of pizza), while a resistance session burns far less. But the chronic structural adaptation to resistance training — preserved muscle mass and strength — pays dividends across decades that a caloric calculation in any single session does not capture.
Mechanism
Resistance training signals muscle protein synthesis through mechanical strain and hormonal responses (IGF-1, testosterone). Regular loading prevents sarcopenia, the age-related loss of muscle mass averaging ~1% per year after age 30 that accelerates after 60. Preserved muscle mass maintains resting metabolic rate, insulin sensitivity, and capacity for all physical activities.
For aging I would say I would put more emphasis on lifting and resistance training rather than endurance training because this is mostly what you need to maintain your functional capacity.
Avoid using BMI or scale weight as the primary treatment target for obesity
WhatReframe obesity treatment away from the scale and toward metabolic health markers, fat distribution, and functional capacity. BMI and total weight are poor proxies for disease risk.
WhenAt the outset of any obesity treatment plan, and when evaluating treatment success.
For whomClinicians treating obesity; individuals in self-directed weight management; anyone interpreting their own health status from scale weight alone.
WhyThe WHO definition of obesity is 'excess fat accumulation that may impair health' — if excess fat is not impairing health, there is no clinical problem. Metabolic markers, visceral fat estimates, and functional measures are better endpoints than weight alone.
CaveatsThis does not mean obesity is benign — MHO is a transient state that becomes metabolically unhealthy with age. The point is that treatment should target the health consequences, not a number on the scale.
Magkos frames this powerfully: 'Would we care about obesity if it were not for the increased risk of disease? No. Obesity would not even be considered by the World Health Organization.' This reframing has implications for clinical communication — telling a patient their weight is a problem is less actionable than telling them their visceral fat is driving insulin resistance and that specific interventions can reverse it without requiring a particular scale number.
Would we care about obesity if it were not for the increased risk of disease? No. Obesity would not even be considered by the WHO because obesity is defined as the amount of excess fat accumulation that may impair health.
Accept individual dietary variability: find the dietary pattern you can maintain for life
WhatStop searching for the one optimal diet. The characteristics of a healthy diet are known (adequate protein, mostly whole foods, plenty of vegetables, controlled energy density); the challenge is finding the specific pattern within those parameters that is sustainable for you as an individual.
WhenOngoing; reframe every dietary 'failure' as data about your personal feasibility envelope.
For whomAnyone with a history of cycling through diets. Especially useful framing for people who conclude they 'failed' a diet rather than that the diet failed to match their life.
WhyDiet is not like a drug that targets one pathway — food contains millions of compounds interacting across every physiological pathway simultaneously. Individual responses to the same dietary intervention vary enormously, and compliance is the single biggest predictor of outcome beyond the first few months.
CaveatsIndividual variation does not excuse extreme diets with known toxicities. The latitude is within a space bounded by adequate protein, sufficient micronutrient density, and energy appropriate to goals.
Magkos gives himself as the example: 70% carbohydrate, 10% protein, 20% fat — a distribution that would be alarming by protein-maximalist standards but works for a 70 kg man running and lifting heavily on 3,500 kcal/day who has found this pattern effortlessly maintainable for years. He explicitly says this would not work for Lyon, who does better on higher protein. The message: use an expert to identify your common errors, then experiment within a safe parameter space. Trial and error is the mechanism, not a sign of confusion.
There is no ideal diet there's no perfect diet and when I say that to people most people get sad and disappointed but I try to give it a positive spin in what sense that there is so many degrees of freedom for you to go out choose experiment and find out the diet that works for you.
GLP-1/dual agonist therapy: effective for weight loss but requires indefinite use
WhatGLP-1 agonists (semaglutide) and dual GIP/GLP-1 agonists (tirzepatide) produce bariatric-surgery-equivalent weight loss but require indefinite use — stopping them returns patients to their prior weight trajectory within months.
WhenAs a medical treatment for obesity when lifestyle interventions have failed; requires physician management and ideally concurrent resistance training and high protein intake to minimize lean mass loss.
DoseIndefinite — not a course of treatment but a maintenance medication, analogous to antihypertensives.
For whomAdults with obesity and metabolic comorbidities when lifestyle interventions alone have been insufficient.
WhyThese agents do not cure the underlying biology of obesity; they suppress appetite via GLP-1 receptor agonism. When withdrawn, the body's defended weight set-point reasserts. Real-world compliance is poor even for motivated patients, and cost/insurance barriers further limit access.
CaveatsReal-world compliance even in motivated patients is low. At a global scale (1.8 billion people with excess weight), universal insurance coverage of these medications would destabilize national healthcare economies. The cost-effectiveness argument only closes if the cardiovascular and metabolic disease prevention benefits are factored in at a population level.
Magkos notes that dual agonists like tirzepatide are already producing weight losses that were previously only achievable with bariatric surgery. This is genuinely new clinical territory. The behavioral evidence suggests patients who respond most rapidly in the first 1–2 months are most likely to sustain results — which may be partially biological. The lean mass concern with GLP-1 agents is real and is precisely where the body composition measurement limitation matters most: if we cannot accurately track muscle loss on these drugs, we may be creating a new epidemic of sarcopenia in people who lose 20–30 kg without concurrent resistance training and protein optimization.
You need to get these drugs forever meaning that if you stop taking these drugs you go back to your initial weight trajectory.
Exercise for weight management: do what you will actually do
WhatThe most beneficial exercise modality is the one an individual will consistently perform. Running, cycling, swimming, lifting, walking the dog — all produce health benefits when done regularly. Do not wait for the 'optimal' exercise type; start with what is accessible and enjoyable.
WhenDaily or near-daily; any movement is better than none.
DoseRunning an hour at moderate-high pace burns ~500 calories. Resistance training burns less acutely but provides structural muscle adaptation that compounds over years.
For whomEveryone, with modality matched to individual capacity, preference, and injury history. For older adults: priority to resistance training. For those short on time: HIIT reaches biological ceiling faster but does not raise it above what longer-duration training would achieve.
WhyExercise's primary weight management value is not its acute caloric burn (a single slice of pizza = one hour of running). Its primary value is behavioral and structural: it creates a positive feedback loop of mindset, dietary attention, and sustainable healthy living, plus long-term preservation of muscle mass and metabolic rate.
CaveatsYou cannot out-exercise a bad diet, and you cannot eat your way out of being sedentary — both are required. Exercise burns far fewer calories than popular perception suggests.
Magkos gives the '500 calories = one hour running = one slice of pizza' framing not to discourage exercise but to reset expectations about why exercise matters for weight. The real mechanism is the behavioral and structural cascade: people who exercise tend to make better dietary choices, sleep better, and feel more capable of the self-regulation that weight management requires. He is personally a high-volume endurance athlete who also lifts 2–3 days per week and cycles to work — his physical activity is spread throughout the entire day rather than concentrated in a single block.
What is the best exercise? Well it's the one you do. That's very simple the answer to that question. It doesn't matter if you lift if you run if you cycle if you swim as long as you do something.
Protein intake for aging adults: offset anabolic resistance by increasing dose
WhatOlder adults exhibit 'anabolic resistance' — a blunted muscle protein synthesis response to the same protein dose that would drive adequate synthesis in younger adults. Counteract this by consuming more protein at each meal to overcome the threshold.
WhenFrom approximately age 50 onward; accelerating priority after 60.
DoseLean toward the upper range of protein intake (toward 2.0–2.2 g/kg) rather than the lower range. Per-meal protein dose may need to be higher than in younger adults to achieve the same synthesis stimulus.
For whomAdults over 50, anyone with sarcopenia or at risk of sarcopenia, patients on GLP-1 agonists where muscle wasting risk is elevated.
WhyInsulin's anti-catabolic role remains intact in aging, but the anabolic side (leucine-triggered mTORC1 activation, IGF-1 sensitivity) is blunted. A larger amino acid bolus is needed to achieve the same net synthesis signal.
Magkos frames the solution as 'flooding the system a little bit more' — the same biological response is achievable in older adults, it simply requires a higher dose to trigger it. This has practical meal-design implications: a 30 g protein portion that satisfies a 30-year-old's synthesis needs may need to become 40–45 g in a 65-year-old. The distribution strategy (protein spread across meals rather than concentrated in one) does not change this ceiling but does affect net daily synthesis by providing more stimulation windows.
Mechanism
Aging associates with reduced mTORC1 sensitivity to leucine, higher splanchnic amino acid extraction, and reduced muscle capillarization that slows amino acid delivery. The net effect is that more dietary protein must be ingested to achieve the same intramuscular leucine concentration that triggers full synthesis activation.
Aging has been associated with a little bit of an anabolic resistance as we call it meaning that for the same amount of protein people who are older they do not respond very robustly in terms of muscle protein synthesis — what you can do to circumvent that problem is to feed them a little bit more protein so if you flood the system a little bit more then you get the same response.

2024 Nature Metabolism consensus paper: energy balance and carbohydrate-insulin models share more than they fight about
~8 min
A NovoAIS Foundation workshop convened ~16 researchers from opposing camps — including Kevin Hall and David Ludwig — in Copenhagen in late 2023. The resulting perspective (Magkos et al., Nature Metabolism, August 2024) mapped the mechanistic overlap between both models and identified the remaining genuine disagreements.
Why this matters: The paper is the first time researchers from both hard camps co-authored a shared summary. Its existence signals more productive territory: collaborative study designs rather than tribal press releases.
Background
Both models agree on normal energy-intake regulation mechanisms; they disagree on causal direction — does positive energy balance precede fat deposition (energy balance model) or does altered peripheral fuel partitioning force overfeeding (carbohydrate-insulin model)?
Magkos took on the task of synthesizing the workshop because he considers himself relatively neutral — able to understand arguments on both sides. Writing the paper took many months and countless drafts because all ~16 co-authors had to agree on specific wording, not just meaning. The key distinction: in the energy balance model, the brain is tricked by the food environment into not sensing how much is eaten; in the carbohydrate-insulin model, the brain correctly perceives that insufficient energy is available (because calories are trapped as fat) and drives eating to compensate. By the end of the workshop, researchers who arrived barely willing to share a breakfast table were designing collaborative study protocols together.
We had a lot of interesting discussion some of them were more heated than others there was a lot of agreement much more much more much more disagreement.
Also said
“Even though they acknowledge that there is a possibility that you know I may be wrong or something else may be happening you know they went back home and they're still believing what they believe.”— Illustrates that consensus on framing does not mean paradigm shift — but the collaborative study designs spawned are the more important outcome.
Visceral and ectopic fat — not total fat — drive metabolic disease risk
~55 min
A person with BMI 40–50 (50 kg excess fat) can be metabolically healthier than someone with normal BMI who has accumulated just 5 kg of visceral fat or 200 g of fat in the liver. The location, not volume, of fat storage is the dominant metabolic risk factor.
Why this matters: Directly undermines BMI as a clinical screening tool and reframes obesity treatment goals away from the scale toward fat distribution and metabolic biomarkers.
Background
Visceral fat and ectopic fat (intrahepatic, intramuscular, intrapancreatic) impair the function of the organs in which they reside — they are metabolically active in ways subcutaneous fat largely is not.
Genetics, diet composition, and exercise habits all influence where excess fat is deposited, but mechanisms are not fully understood. This is why two people on identical diets can have wildly different metabolic outcomes. Lyon challenged Magkos on 'metabolically healthy obesity' (MHO), arguing it is time-limited — younger individuals can mask complications for years, but MHO prevalence shrinks almost linearly with age even without weight gain. Magkos agreed: MHO is not a permanent condition, it's a temporary one that becomes increasingly unstable over time.
You can have a person with obesity right in a BMI of 40 or 50 so you can have 50 kilograms of extra fat in your body but that doesn't necessarily tell you much as if you accumulate only let's say 5 kilograms as visceral adipose tissue or 200 grams of fat in your liver.
Also said
“These individuals tend to be younger right and we know for a fact that as we age the chances that we are staying metabolically healthy are diminishing almost linearly even if your weight does not increase.”— Confirms that metabolically healthy obesity is a transient phenotype, not a stable state — reframes it as a countdown, not a classification.
Rapid initial weight loss predicts long-term success — not failure
~1 h 02 min
Counter to the conventional warning that rapid weight loss leads to worse outcomes, multiple RCTs (Look AHEAD, HASD, others) show that people who lose weight fastest in the first 1–2 months maintain the most weight loss years later. After 1 month of weight stabilization at the new lower body weight, composition differences between fast and slow losers largely disappear.
Why this matters: Contradicts the widely-repeated advice that 'slow and steady' protects lean mass. Rapid initial response may reflect favorable biology, not unsustainable restriction.
Background
The confound in prior studies measuring composition differences between fast and slow losers is water flux — many apparent lean mass differences measured at the end of a restriction phase normalize once the body stabilizes at the new weight.
The two most robust predictors of long-term weight loss success are: (1) compliance with the diet and (2) initial rate of weight loss. Compliance is easily explained by motivation in the early weeks, but the biological element of rapid response is independent of compliance and predicts outcomes 4–8 years later — a finding that has appeared consistently across several large trials. Magkos emphasizes this is all without medication; the GLP-1 era introduces a different dynamic where rapid pharmacological weight loss may not carry the same biological signal.
People who for some reason lose weight initially at a faster rate are those who are more successful in long-term weight loss whether it's biological whether it's something else we do not know the mechanisms but this observation comes again and again that rapid initial weight loss predicts longer success.
Body composition measurement tools are insufficiently precise to detect true muscle loss in weight loss studies
~1 h 18 min
The gold standard for muscle mass quantification is whole-body CT or MRI, which is prohibitively expensive in large trials. Most weight-loss studies use bioelectrical impedance (BIA) or DXA — neither of which can isolate skeletal muscle from other lean mass, leading to systematic underestimation of muscle's role in metabolic outcomes.
Why this matters: The field may be consistently underpowered to detect the very muscle-centric outcomes that matter most for longevity and metabolic health — a methodological gap with clinical consequence.
Background
DXA outputs fat mass and lean mass (everything non-fat, non-water, non-bone) but cannot distinguish muscle from organ mass, connective tissue, or intramuscular fat. BIA uses tissue conductivity as a proxy and is further degraded by hydration status.
Lyon argues this has been a 'huge disservice' — that failure to accurately measure muscle mass has allowed clinical obesity trials to under-report and under-weight the significance of muscle loss during weight loss interventions. Magkos agrees on the methodological limitation but notes that obesity trials historically have not been muscle-centric in their design; allocating resources for whole-body CT/MRI was simply not in scope. The next generation of studies, particularly those examining GLP-1 effects on body composition, may force the field to upgrade its measurement standards because the magnitude of lean mass loss on semaglutide is clinically significant.
The majority of studies I would say that focus on the treatment of obesity they are not so muscle-centric to put it this way.
Also said
“If you really want to be very specific about muscle you would probably have to resolve to methods including either CT like computer tomography or magnetic resonance imaging and you would have to do it at the whole body level.”— Sets the gold standard explicitly — and explains why it almost never appears in nutrition research.
Breakfast timing myths: observational data on breakfast and body weight is reverse causal
~2 h 10 min
Population studies show breakfast-skippers are more obese — but when habitual breakfast-skippers are randomized to eat breakfast, they gain weight, not lose it. Separately, when calorie intake is equated and meal frequency is randomized (one large meal vs. six smaller meals), there are no differences in weight or body composition outcomes.
Why this matters: Two common prescriptions — 'eat breakfast to lose weight' and 'graze through the day for better metabolism' — fail controlled tests, even though their epidemiological signals look compelling.
Background
Confounding explains the epidemiology: breakfast-skippers are a self-selected group with other behavioral and metabolic characteristics associated with higher BMI. Forcing the habit on people without those characteristics reverses the effect.
Magkos is himself a habitual breakfast-skipper who gains weight when forced to eat breakfast in studies. He uses this as a personal illustration of how observational nutrition findings can be entirely uninformative — or directionally wrong — for individuals. The meal frequency finding (one meal vs. six meals, same total calories) has been replicated repeatedly; when total intake is controlled, distribution across the day does not independently affect body composition. The practical message: these factors likely matter for some people with specific biological profiles, but neither breakfast timing nor meal frequency is a universal lever for weight management.
If you take people who are habitual not breakfast eaters like myself and you put them in a study and you tell them now start eating breakfast we gain weight we don't lose weight.
Also said
“When we randomize them on one month to eat one meal all calories of the day in one meal versus spread out in six meals we do not see any differences.”— Controlled evidence that meal frequency, when calories are held constant, does not independently drive body composition.
Environmental contaminants as an underappreciated obesity driver — basal metabolic rate has been declining since 1910
~22 min
Evidence suggests human basal metabolic rate has been declining since 1910, well before the obesogenic food environment. Environmental contaminants (pesticides, endocrine disruptors) are a plausible contributing factor — illustrated by a military dog that gained extreme weight rapidly after pesticide exposure without any change in food intake.
Why this matters: Most obesity discourse focuses on calories and macros; a metabolic-rate decline predating processed food suggests the environment-contaminant pathway may be underweighted in the causal chain.
Background
This is one of the 'other models' briefly surfaced at the Copenhagen workshop but not the focus of the main debate. Magkos flags it as plausible but understudied.
The dog anecdote is striking: same food, same owner, dramatic rapid obesity onset attributable to pesticide exposure on a golf course — along with vision loss in one eye. Magkos uses it to illustrate that multiple causal pathways can operate simultaneously and that for any given individual, the dominant driver may be different from the population average. The declining basal metabolic rate signal suggests something physiological was already changing before ultra-processed food scaled, which neither the energy balance nor the carbohydrate-insulin model cleanly explains.
There is evidence that the basal metabolic rate of humans has been decreasing over the past 100 years, which is much prior to the emergence of the obesogenic environment as we call it today.

Lines worth pulling out — contrarian, specific, or perfectly phrased
6 items
You can have a person with obesity right in a BMI of 40 or 50 so you can have 50 kilograms of extra fat in your body but that doesn't necessarily tell you much as if you accumulate only let's say 5 kilograms as visceral adipose tissue or 200 grams of fat in your liver.
Single most actionable reframe in the episode: fat location matters vastly more than fat quantity, and BMI is the wrong measurement.
Would we care about obesity if it were not for the increased risk of disease? No. Obesity would not even be considered by the World Health Organization because obesity is defined as the amount of excess fat accumulation that may impair health.
Forces a complete reframing: the target of treatment is not weight, it is health impairment. This shifts the goalposts and the success criteria.
You cannot out-exercise a bad diet in the same way that you cannot eat your way out of being sedentary.
Symmetric framing of a common asymmetric misconception — most people believe the first half but not the second half, which is equally true and actionable.
Rapid initial weight loss predicts longer success... this observation comes again and again that rapid initial weight loss predicts longer success.
Directly contradicts the dominant slow-and-steady narrative with multi-trial evidence. Reframes early success as biology, not unsustainable behavior.
There is no ideal diet there's no perfect diet and when I say that to people most people get sad and disappointed but I try to give it a positive spin in what sense that there is so many degrees of freedom for you to go out choose experiment and find out the diet that works for you.
Unusually honest concession from a full professor — and psychologically liberating rather than nihilistic because it frames degrees of freedom as an opportunity.
Science is a science of uncertainty — when we say in science and in our research that something is happening we always say that with a certain level of being uncertain which means that it might not always happen this way and it might not always happen for everybody in the same way.
The epistemological frame Magkos applies to every claim in the episode — and a direct corrective to the absolutism that characterizes most public nutrition discourse.
