Well SupportedStearic acid ingestion increases circulating C18 triglycerides and activates mitochondrial beta-oxidation.Well SupportedStearic acid, enriched in animal foods and absent in plant foods, signals the body to burn fat, and its deprivation leads to fragmented mitochondria.Well SupportedDietary stearic acid regulates mitochondrial function in humans, with stearic acid deprivation leading to decreased mitochondrial activation and fragmentation.Well SupportedDietary stearic acid reduced visceral adipose tissue by 70% and increased lean body mass in rats compared to oleic and linoleic acid diets.Well Supported

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

Animal fats, particularly stearic acid found in suet, are nutritious and can be supplemented.

Well SupportedThe supplement 'Fire Starter' from Heart & Soil Supplements, made from high stearic acid tallow, may lead to fat loss, increased energy, and improved exercise capacity.

Well SupportedStearic acid enrichment in the diet protected against type 2 diabetes progression in mice.

Well SupportedDietary stearic acid reduced visceral adipose tissue and was associated with reduced metastatic tumor burden in athymic nude mice.

Partially SupportedBeef kidney fat (suet) contains approximately 33% stearic acid, while beef intramuscular fat contains about 23% stearic acid.

Partially SupportedAnimal studies on fructose metabolism are not directly applicable to humans due to significant biochemical differences.

Partially SupportedSaturated fats, such as lauric, myristic, palmitic, and stearic acids, have no double bonds between carbon atoms.

Partially SupportedMice fed a diet high in stearic acid and starch had the least body weight and kidney fat compared to mice fed other fat compositions.

Partially SupportedLinoleic acid is unstable due to its multiple double bonds, making it prone to oxidation.

Partially SupportedStearic acid, prevalent in animal fat, suet, and cacao butter, may have an anti-metastatic effect in breast cancer.

Partially SupportedDietary stearate may inhibit breast cancer cell proliferation and reduce tumor burden.

Partially SupportedConsuming tallow pills before social events with junk food can improve satiety and provide energy.

Partially SupportedStearic acid causes increased programmed cell death in pre-adipocytes, leading to a loss of visceral adipose tissue cells.

Partially SupportedTo return to an optimal metabolic state and change tissue composition, linoleic acid levels must be reduced to low single digits.

Partially SupportedLinoleic acid may signal the body to gain fat by allowing adipocytes to expand, while saturated fats, particularly stearic acid, signal fat cells to shrink.

Partially SupportedEvolutionarily, stearic acid is predominantly found in animal foods, particularly suet.

Partially SupportedHardened Soil is developing a high stearic acid tallow product called 'Fire Starter'.

Not SupportedA low-fat vegan diet led to mitochondrial fragmentation.

Partially SupportedSaturated fats like stearic acid may affect brain satiety centers, contributing to feeling full.

Partially SupportedThe double bonds in fatty acids like linoleic acid affect the FADH2 to NADH ratio during beta-oxidation, influencing ROS production.

Partially SupportedThe 'Croissant Diet' high in stearic acid butter and flour led to 7kg weight loss in two months.

Partially SupportedFollowing a low-stearic acid vegan diet for two days decreased blood stearic acid levels in humans.

Partially SupportedA subject on a strict carnivore diet primarily consisting of pork, chicken, and fish was unable to lose weight and experienced rapid hunger.

Partially SupportedA low linoleic acid diet is part of Paul Saladino's experimentation, aiming for 5.3% linoleic acid in red blood cells.

Not SupportedDiabetic mice fed oleic acid and chow diets exhibited decreased insulin responsiveness and disorganized islet cells compared to those fed stearic acid.

Partially SupportedLinoleic acid is found in nuts and seeds, which may have been consumed in the fall to gain fat for winter survival.

Partially SupportedInsulin resistance in adipocytes may be related to linoleic acid signaling fat cells to grow while stearic acid signals them not to grow or to shrink.

Limited ResearchOlive oil may increase visceral fat in mouse models.

Partially SupportedIncreased reactive oxygen species production can lead to cells turning off insulin signaling.

Partially SupportedHigh stearic acid levels, such as 19%, in blood work are desirable.

Partially SupportedVisceral fat is related to metastasis and decreased survival.

Partially SupportedLow palmitic acid levels may indicate insulin sensitivity and metabolic health.

Partially SupportedIncreasing stearic acid intake and reducing linoleic acid sources can lead to weight loss after other diets failed.

Partially SupportedConsuming stearic acid can improve the absorption of other supplements.

Not SupportedVegan diets are low in stearic acid, which is considered detrimental.
