✓Well SupportedContinuous glucose monitors (CGMs) provide insight into dietary impacts on glucose, with most learning occurring within 30-90 days.✓Well SupportedProtein is highly satiating and has a higher thermic effect than carbohydrates.✓Well SupportedContinuous Glucose Monitors (CGMs) are likely only needed for 2-4 weeks to collect useful data on individual food responses because these responses are generally repeatable.◐Partially SupportedA postprandial blood sugar reading of 150 mg/dL is not a concern for individuals with consistently low fasting insulin (<3 micro IU/mL) and healthy metabolic markers.Well Supported

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

A Mean Amplitude of Glycemic Excursions (MAGE) limit of 50 or 60 may be acceptable for very low-risk individuals.

◐Partially SupportedPlain boiled potatoes are highly satiating, likely due to their texture and the difficulty in consuming large quantities.

◐Partially SupportedProcessed carbohydrates, such as ground and boiled grains, cause a larger blood sugar spike compared to whole, cooked grains.

◐Partially SupportedThe energy-based model proposed by Kevin Hall is the most accurate model of energy metabolism and obesity currently.

◐Partially SupportedFocusing on body composition, movement, and diet quality may mitigate negative impacts associated with blood sugar levels.

◐Partially SupportedA postprandial blood sugar spike to 150 mg/dL is not a concern in individuals with fasting insulin below 3 micro IU/mL.

◐Partially SupportedLarge and frequent blood sugar spikes negatively impact long-term health, potentially contributing to atherosclerosis risk, diabetes risk, and affecting endothelial function, blood-brain barrier function, and brain cells.

◐Partially SupportedStearic acid may affect mitochondrial function, fusion, and beta-oxidation, as suggested by studies in vegans.

◐Partially SupportedShort-term mechanistic studies on specific nutrients do not necessarily predict long-term outcomes such as satiety, total calorie intake, body composition, or long-term health.

◐Partially SupportedDipeptidyl peptidase-4 (DPP-4) inhibitors were associated with improved cognitive function in older individuals, alongside weight loss and improved body composition.

◐Partially SupportedBelieving a food will cause a blood sugar spike can lead to a larger spike.
