FASTER data on fatty
acid oxidation rate The Crossover Point: The Crossover Point Hypothesis was developed and studied by George Brooks et.al.
The mean fatty
acid oxidation rate was OVER twice the rate of the high carbohydrate cohort (1.54 gm / min vs. 0.67 gm / min).

As a summary, based on numerous studies, if your goal is to increase mitochondrial density and as a result increase the
rate of fatty
acid oxidation or fat loss, focus your training program around strength training and HIIT, and eat a diet which is rich in protein and low - glycemic carbs.
Essential fatty
acids (Omega - 3 and Omega - 6) increase
oxidation rate, increase metabolic
rate, increase energy levels and increase stamina.
Aside from studies on obese mice, limited research has also shown reduced blood pressure, increased fat burning and increased fatty
acid oxidation later in the fast, and increased metabolic
rate due to the release of epinephrine and norepinephrine (again, later in the fasting period).
More specifically, these
acids have the ability to increase the
rate of fat burning by stimulating the activity of enzymes in the liver involved in fat breakdown and
oxidation and diminishing the activity of enzymes that promote fat storage, which leads to an improved fatty
acid and glucose metabolism.
Studies in rodents have additionally described post-treatment elevations in the
rate of fatty
acid oxidation within both the liver and skeletal muscle of mice maintained on IER (100 % ER / alternate days).13 In a comparison of CER (40 % ER / day) and IER (100 % ER / alternate days), the authors of this 20 - week study noted a doubling in the Î ² - hydroxybutyrate levels (a marker of mitochondrial fatty
acid oxidation) in IER - fed mice which was not present in the CER group.15 Both IER and CER interventions led to comparable reductions in fasting levels of glucose and insulin.
The lowest
rate of fat
oxidation in a LCD subject was 1.1 grams / minute which is higher than what the current published literature suggests is possible with one subject actually recording a
rate of 1.8 grams / minute of fatty
acid oxidation!
• widespread effects on circulation, muscles and sugar metabolism • raised heart
rate • increased heart output • increased
rate and depth of breathing • increased metabolic
rate • increased force of muscular contraction • delayed muscular fatigue • reduced blood flow to bladder (muscular walls relax and sphincters contract) • reduced blood flow to intestines • increased blood pressure • increased sugar (glucose) in the blood • increased break - down of glucose for energy *, especially in muscle cells • increased free fatty
acids in the blood * • more
oxidation of fatty
acids to produce energy * • more ATP (the cells» primary energy compound) produced * • blood vessels constrict
South African researchers conducted a review on MCTs for performance enhancement in 1998 and concluded, «In the search for strategies to improve athletic performance, recent interest has focused on several nutritional procedures which may theoretically promote FA [fatty
acid]
oxidation, attenuate the
rate of muscle glycogen depletion and improve exercise capacity... At present, there is insufficient scientific evidence to recommend that athletes either ingest fat, in the form of MCTs, during exercise...» 163
According to the biochemistry of fatty
acid oxidation, transport is the
RATE LIMITING STEP for
oxidation of long chain fatty
acids.
In addition, the high
rate of amino
acid catabolism allows for a readily available source of energy via direct
oxidation or as a substrate for hepatic gluconeogenesis.
