A ketogenic diet (KD) is a normocaloric diet composed by high fat (80-90%), low carbohydrate, and low protein consumption that induces fasting-like effects. KD increases ketone body (KBs) production and its concentration in the blood, providing the brain an alternative energy supply that enhances oxidative mitochondrial metabolism. In addition to its profound impact on neuro-metabolism and bioenergetics, the neuroprotective effect of specific polyunsaturated fatty acids and KBs involves pleiotropic mechanisms, such as the modulation of neuronal membrane excitability, inflammation, or reactive oxygen species production...

BACKGROUND: The use of bulls rather than steers for beef production offers some considerable advantages, however, the eating quality of bull beef is an issue of marketing concern. This study assessed the physico-chemical characteristics of young Holstein-Friesian (HF) bull and steer beef. Steer carcasses were suspended by the Achilles tendon (AS) and by Pelvic suspension (PS). RESULTS: HF Steer beef had higher redness, yellowness, and chroma values, while bulls had higher ultimate pH and darker muscle...

Long-chain fatty acids (LCFA) are known to activate brown and beige adipocytes. However, very little is known about the effects of the number and the position of double bonds in LCFA with the same length on brown fat-specific gene expression. To determine the specificity of LCFA in the regulation of these genes in different adipocyte models, fully differentiated 10T1/2, 3T3-L1, murine, or porcine primary adipocytes (obtained from the subcutaneous fat pad of C57BL/6 mice or Landrace × Yorkshire × Duroc crossbred piglets) were treated with 50 μM of the following 18-carbon fatty acids: stearic acid (STA; 18:0), oleic acid (OLA; 18:1, Δ9), linoleic acid (LNA; 18:2, Δ9,12), α-linolenic acid (ALA; 18:3, Δ9,12,15), γ-linolenic acid (GLA; 18:3, Δ6,9,12), or pinolenic acid (PLA; 18:3, Δ5,9,12) for 24 h with or without 4-h norepinephrine (NE) treatment...

Intramuscular fat (IMF) content and composition are considered crucial indicators of porcine meat quality. However, the molecular mechanism of porcine IMF development is still mostly unclear. Recently, new evidence suggested that microRNA (miRNAs) play important roles in porcine intramuscular adipogenesis. Previously, microRNA-125a-5p (miR-125a-5p) was identified as an important regulator of adipogenesis. In the present study, we found that the expression of miR-125a-5p is dynamically regulated during porcine intramuscular preadipocytes differentiation and that its expression levels in different porcine muscle tissues were negatively involved with IMF content...

Thirty six male goats grazing Caatinga native pasture were randomly assigned to 4 concentrate supplementation levels (0, 5, 10 and 15g/kg of body weight) and slaughtered after 120days. Longissimus muscle meat lipids were extracted and fractionated into neutral (NL) and polar (PL) lipids. Supplementation of grazing goats increased linearly (P<0.05) intramuscular fat (1 to 1.5% of meat) and NL (0.3 to 1% of meat) but decreased linearly (P=0.044) the PL (0.66 to 0.50% of meat). On NL, supplementation increased linearly (P=0...

Omega-3 polyunsaturated fatty acids (n-3 PUFAs) have been reported to improve insulin sensitivity and glucose homeostasis in animal models of insulin resistance, but the involved mechanisms still remain unresolved. In this study, we evaluated the effects of fish oil (FO), a source of n-3 PUFAs, on obesity, insulin resistance and muscle mitochondrial function in mice fed a high-fat diet (HFD). C57Bl/6 male mice, 8 weeks old, were divided into four groups: control diet (C), high-fat diet (H), C+FO (CFO) and H+FO (HFO)...

Polyunsaturated fatty acids (PUFA) have important signalling roles in the hypothalamus, a region of the brain that regulates whole-body energy homeostasis. While evidence suggests that high PUFA intake can impact hypothalamic activity, the underlying molecular mechanisms regulated by essential dietary n-6 and n-3 PUFA (i.e., linoleic acid and α-linolenic acid, respectively) remain poorly described in this brain region. To differentiate the roles of essential dietary PUFA on hypothalamic function, we fed male rats high-fat diets (35% kcal/d) containing either safflower (linoleic acid) or flaxseed (α-linolenic acid) oil for 2 months...

The aim of present study was to investigate the effect of different dietary oils and the dietary energy restriction on the activity of enzymes participating in the process of arachidonic acid synthesis and on fatty acid profile in serum. It was also evaluated how diet modification affects the weight of animals and weight of the specific organs: liver, kidney and spleen. Wistar male rats were divided into 6 groups according to the diet fed (control, sunflower oil, olive oil, rapeseed oil, fish oil and a group of dietary energy restriction - DER group)...

PURPOSE OF REVIEW: Maternal lipid metabolism greatly changes during pregnancy and we review in this article how they influence fetal adiposity and growth under non-diabetic and gestational diabetic conditions. RECENT FINDINGS: In pregnant women without diabetes (control), maternal glycemia correlates with neonatal glycemia, neonatal body weight and fat mass. In pregnant women with gestational diabetes mellitus (GDM), maternal glucose correlates with neither neonatal glycemia, neonatal birth weight nor fat mass, but maternal triacylglycerols (TAG), non-esterified fatty acids (NEFA) and glycerol do correlate with birth weight and neonatal adiposity...

OBJECTIVE: Regulation of fatty acid (FA) metabolism is central to adipocyte dysfunction during diet-induced obesity (DIO). Long-chain acyl-CoA synthetase-4 (ACSL4) has been hypothesized to modulate the metabolic fates of polyunsaturated FA (PUFA), including arachidonic acid (AA), but the in vivo actions of ACSL4 are unknown. The purpose of our studies was to determine the in vivo role of adipocyte ACSL4 in regulating obesity-associated adipocyte dysfunction. METHODS: We developed a novel mouse model with adipocyte-specific ablation of ACSL4 (Ad-KO) using loxP Cre recombinase technology...

We recently demonstrated that the prevalence of dysglycemia was high among hospitalized elderly people who were fed a low fat diet (27.7% of energy) and was positively associated with plasma 16:1n-7, an indicator of de novo lipogenesis (DNL). Fatty acids in the DNL pathway have been shown to be associated with a higher risk of metabolic syndrome (MetS). The purpose of this study was to investigate the potential beneficial effects of fat enrichment (up to 34.1%en) of the hospital diet in 111 patients (30 men and 81 women, 84 ± 7 years) during 6 weeks...

Obesity is a major driver of metabolic diseases such as nonalcoholic fatty liver disease, certain cancers, and insulin resistance. However, there are no effective drugs to treat obesity. Betaine is a nontoxic, chemically stable and naturally occurring molecule. This study shows that dietary betaine supplementation significantly inhibits the white fat production in a high-fat diet (HFD)-induced obese mice. This might be due to betaine preventing the formation of new white fat (WAT), and guiding the original WAT to burn through stimulated mitochondrial biogenesis and promoting browning of WAT...
