What is Sesamin?
Sesamin is a naturally occurring lignan
that is present in pure sesame oil. For your information, a lignan is
broadly considered an antioxidant that is present in unfiltered and unrefined
seeds of sesame, pumpkin and flax as well as many other foods. Besides
being a strong antioxidant, sesamin has shown great promise as a lipid
oxidizer as well as to support anti-inflammatory action. Its main mechanism
for fatty acid oxidation (fat burning) is triggered by the enzyme known
as PPAR-alpha. PPAR-alpha (Peroxisome Proliferator-Activator Receptor
Alpha) is documented to exist in muscle, the liver and adipose tissue
(fat). Sesamin being a strong activator of this enzyme (PPAR-alpha) is
therefore involved in the oxidation of fatty acids while simultaneously
decreasing lipogenesis. In other words, PPAR-alpha activation is directly correlated with
increasing fat burning in muscle tissue. Which is a good thing!!!
Sesamin and Insulin Sensitivity
Due to sesamin’s strong beta-oxidizing properties the substance can also
affect leptin levels and thus restores insulin sensitivity
in obese rodents†. Insulin sensitivity is often impaired in those whose
body fat levels exceed 15% and higher. In more simple terms, by providing
the necessary substrate; sesamin is believed to act as a thermostat of
sorts that can regulate leptin as well as insulin levels from within the
body keeping both in optimal balance.
Sesamin and Ketosis
Sesamin is a welcomed addition for those who are on ketogenic diets as
it is known to increase ketone production thereby sparing lean muscle
tissue. Ketogenesis (or the formation of ketones)
becomes a major fuel factor on low carb (Atkins) diets as the brain cannot
be driven by fatty acids and thereby relies on glucose first..and ketones
second. So essentially, without Sesamin in your diet, the body will tap
into muscle tissue for its ketone needs since carbohydrates are
kept very low on Atkins or other prominent diets such as South Beach etc.
In Closing
Sesamin is an excellent addition for anybody’s workout regimen, not only
to increase fat burning, but also for its overall anti-oxidant and nutrient
partioning properties. Some of the later research†† even points out that
Sesamin shows great promise in the lowering of LDL (bad) cholesterol while
simultaneously increasing HDL (good) cholesterol levels in humans. **
