Carnitine and Fat Oxidation [PDF]

, 2013
Fat and carbohydrate are the primary fuel sources for mitochondrial ATP production in human skeletal muscle during endurance exercise. However, fat exhibits a relatively low maximal rate of oxidation in vivo, which begins to decline at around 65% of maximal oxygen consumption (VO₂max) when muscle glycogen becomes the major fuel.

Effect of Fat Mass Localization on Fat Oxidation During Endurance Exercise in Women

Frontiers in Physiology, 2020
Independent of total body fat mass, predominant upper body fat mass distribution is strongly associated with cardio-metabolic comorbidities. However, the mechanisms underlying fat mass localization are not fully understood.

β-Hydroxybutyrate Oxidation in Exercise Is Impaired by Low-Carbohydrate and High-Fat Availability

Frontiers in Medicine, 2021
Purpose: In this study, we determined ketone oxidation rates in athletes under metabolic conditions of high and low carbohydrate (CHO) and fat availability.Methods: Six healthy male athletes completed 1 h of bicycle ergometer exercise at 75% maximal ...

The effects of Montmorency tart cherry juice supplementation and FATMAX exercise on fat oxidation rates and cardio-metabolic markers in healthy humans [PDF]

, 2018
Montmorency tart cherries (Prunus cerasus L.) are rich in anthocyanins, compounds capable of augmenting fat oxidation and regulating metabolic dysfunction.

Opposing activity changes in AMP deaminase and AMP-activated protein kinase in the hibernating ground squirrel. [PDF]

PLoS ONE, 2015
Hibernating animals develop fatty liver when active in summertime and undergo a switch to a fat oxidation state in the winter. We hypothesized that this switch might be determined by AMP and the dominance of opposing effects: metabolism through AMP ...

Impact of phenylketonuria type meal on appetite, thermic effect of feeding and postprandial fat oxidation [PDF]

, 2018
Background: Dietary management of phenylketonuria (PKU) requires the replacement of natural protein-containing foods with special low protein foods.

Oxidized fats in foods

Current Opinion in Clinical Nutrition and Metabolic Care, 2003
Lipid oxidation is the cause of important deteriorative changes in chemical, sensory and nutritional food properties. In particular, the question of whether oxidized fats in the diet may be detrimental to health is nowadays of the upmost concern, but finding an answer is not easy and requires careful consideration of different aspects of lipid ...

p66Shc-generated Oxidative Signal Promotes Fat Accumulation [PDF]

Journal of Biological Chemistry, 2008
Reactive oxygen species (ROS) and insulin signaling in the adipose tissue are critical determinants of aging and age-associated diseases. It is not clear, however, if they represent independent factors or they are mechanistically linked. We investigated the effects of ROS on insulin signaling using as model system the p66(Shc)-null mice.

High dietary fat intake increases fat oxidation and reduces skeletal muscle mitochondrial respiration in trained humans. [PDF]

, 2018
High-fat, low-carbohydrate (CHO) diets increase whole-body rates of fat oxidation and down-regulate CHO metabolism. We measured substrate utilization and skeletal muscle mitochondrial respiration to determine whether these adaptations are driven by high ...
