Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

Partially SupportedEight Sleep users report falling asleep 32% faster, reducing sleep interruptions by 40%, and experiencing more restful sleep.

Partially SupportedMany participants from 'The Biggest Loser' regained weight with persistent metabolic suppression six years later.

Partially SupportedThe body appears to homeostatically maintain total energy expenditure within a narrow band.

Not SupportedCarbohydrates, including grain-based ones, are not the primary problem for human health and do not necessarily create insulin resistance or metabolic dysfunction.

Well SupportedIncreasing protein and fiber intake can lead to greater satiety on fewer calories.

Partially SupportedWeight loss requires considering calorie sources, physiological impacts, and non-exercise activity thermogenesis, not just calories in and calories out.

Partially SupportedIf health issues persist after adopting a whole-food diet, further investigation into specific food compounds like lectins that may trigger biological responses or gut problems is warranted.

Partially SupportedA species-appropriate diet for humans is one obtained through hunting and gathering, with a preference for hunting.

Partially SupportedThe Hadza people have low prevalence of hypertension, elevated fasting glucose, type 2 diabetes, and stable body weight throughout adulthood.

Partially SupportedStandard mattresses can absorb body heat, leading to night sweats and restlessness that disrupt the circadian rhythm.

Partially SupportedHigh fructose corn syrup has a similar fructose to glucose ratio as honey.

Partially SupportedThe consumption of honey, sucrose, and high fructose corn syrup produces similar metabolic effects in both glucose-tolerant and glucose-intolerant individuals.

Partially SupportedThe Hadza diet can derive 15% or more of its energy from honey and sugars, indicating it is not a low-carbohydrate diet.

Partially SupportedRegenerative agriculture sequesters carbon into the soil and improves mycorrhizal fungal networks.

Well SupportedSoybean oil can affect hypothalamic gene expression, oxytocinergic expression, and potentially lead to obesity.

Partially SupportedThe Hadza people's bows have draw weights of around 70-80 pounds, equivalent to a one-arm pull-up for individuals of their stature.

Partially SupportedAn animal-based diet consisting of meat, organs, and the least toxic plant foods is part of 'the remembering' of human origins.

Partially SupportedThe development of hunting and gathering around 2-2.5 million years ago provided a flexible lifestyle that allowed early Homo species to find food anywhere.

Partially SupportedWhen physical activity is reduced, the body may expend calories on inflammation, stress reactivity, or higher reproductive hormones.

Partially SupportedDietary quality is the most significant factor for metabolic health and weight loss.

Partially SupportedWeight loss is primarily achieved through diet, not excessive exercise.

Partially SupportedThe hunting and foraging strategy involves high levels of moderate to vigorous physical activity, supporting the evolutionary medicine model for the relationship between MVPA and cardiovascular health.

Partially SupportedAdulterated honey may not yield the same metabolic results as pure honey.

Partially SupportedThe body down-regulates other functions to maintain total energy expenditure within a constrained range, even with increased physical activity.

Partially SupportedThere are many selections of food that can support human health, and within these, individuals may react differently to certain whole foods from an immune perspective.

Partially SupportedDiet intervention alone resulted in indistinguishable weight loss compared to diet plus exercise in overweight/obese Boston policemen.

Partially SupportedProcessed foods may negatively impact hypothalamic function, gene transcription, and hormone secretion.

Partially SupportedCalorie quality may affect calorie expenditure by influencing hypothalamic regulation of satiety.

Partially SupportedSugar consumed as honey may not be problematic due to its natural composition, unlike sucrose or high-fructose corn syrup.

Not SupportedThe 'Biggest Loser' approach to weight loss is ineffective because the body reduces energy expenditure, making it harder to achieve an energy deficit.

Partially SupportedEating foods found in nature in ratios consistent with natural patterns is foundational for human health.

Partially SupportedDiets tend to fail because people do not like them, citing flavor and lack of fullness as reasons for non-adherence.

Not SupportedThe paleo diet interpretation that all ancestral diets were exclusively meat-based is not supported by anthropological data.

Partially SupportedKetogenic and very low-carbohydrate diets do not appear to significantly alter resting metabolic rates compared to high-carbohydrate diets.

Partially SupportedHuman metabolic rates are approximately 20% higher than those of chimpanzees, even after accounting for body size, composition, and activity levels.

Partially SupportedTotal daily energy expenditure in Hadza hunter-gatherers is the same as in populations in the US and Europe, despite higher activity levels.

Partially SupportedHumans appear to be evolutionarily programmed to burn 2500-3000 calories per day.

Partially SupportedUgali consumption by the Datoga did not appear to cause obesity or significant metabolic health issues.

Partially SupportedConsumption of red meat and ruminant meat by populations like the Hadza does not appear to negatively impact cardiovascular health.

Partially SupportedThe quality and oxidation state of fats, along with substances co-occurring with sugar, are critical for obesity research.

Partially SupportedExercise is not the primary method for humans to lose weight, although movement is essential for human well-being.

Partially SupportedExercise is necessary for maintaining weight loss after an initial weight loss period achieved through diet.

Partially SupportedVeganism and keto are not the only ways to achieve a healthy diet; other approaches can also be effective.

Partially SupportedIn a typical hunter-gatherer physiology, calories are primarily spent on physical activity.

Not SupportedThe common advice 'eat less, move more' is ineffective for improving dietary quality and overall health.

Partially SupportedPrioritizing whole foods over processed foods helps individuals find a sustainable and enjoyable diet.

Partially SupportedBody temperature affects circadian rhythm and sleep quality.

Not SupportedThe 'Biggest Loser' show models a detrimental approach to weight loss.

Partially SupportedUgali does not appear to cause significant metabolic health issues or immediate diabetes in the studied population.

Partially SupportedExercise acts as a regulatory mechanism by consuming calories that would otherwise be spent on detrimental processes like inflammation.

Partially SupportedThe hypothalamus plays a role in metabolic changes during perceived starvation, signaling the body to reduce metabolic rate.
