Sesamin For Fat Loss

[The Anonymizer]

Bye, Bye Fatty. Hello Sesamin!

Houseman @ MuscleNexus

When one diets to lose fat, it is relatively easy to lose those first 5-10 pounds of fat. After that initial stage of fat loss, the body begins to make it harder to lose more fat and easier to regain fat by reducing the concentrations of "fat-burning" enzymes and up-regulating the "fat storage" enzymes. These changes in enzyme activity play a big role in the cessation of fat loss and lack of progress experienced by dieters. The body wants to function in a specific range of body fat referred to as the body's "set point." The body functions optimally at its set point level of body fat and therefore attempts to keep its fat storages at this set point.

In an attempt to override the bodies desire to keep its fat storage near its set point, dieters often take weight loss supplements, such as thermogenics. The problem with most weight loss supplements is they do nothing to override the body's desire to stop fat loss and merely provide a means to boost one's metabolism for a short while. While such supplement may help one lose a little more fat, they are only a short-term solution for dieters. Thermogenics, such as ephedrine, aid in fat loss by causing fat cells to release fatty acids. The body has a fixed capacity for fat loss and if enzyme activity has been shifted to promote fat storage over fat oxidation, releasing fatty acids from fat cells will be of little use if they cannot be oxidized.

In order to successfully lose fat, one must create a stimulus that tells the body to burn more fat and to stop storing/trying to store fat. Sesamin, a lignan found in sesame seeds, has been shown to do just that-make the body oxidize more fat and increase its capacity to do so while decreasing the storage of fat.

Sesamin and the Peroxisome Proliferator-Activated Receptors (PPAR)
Sesamin is a lignan isolated from sesame seeds. A lignan is a molecule that combines with another entity acting as an "activator." In the case of sesamin, it binds to and activates a receptor called Peroxisome Proliferator-Activator Receptor Alpha (PPARalpha). The PPAR receptor family is divided into three subgroups: alpha, delta, and gamma. PPARalpha is highly expressed in muscle, the liver, kidneys, and heart and is involved in the regulation of lipid metabolism, specifically the transcription of the genes involved in the beta-oxidation (burning) of fatty acids and lipogenesis. Activation of PPARalpha increases gene expression of the fatty acid oxidation enzymes and decreases gene expression of lipogenic enzymes. Sesamin has been shown to be a potent PPARalpha activator [1].

Sesamin, Mitochondria, Peroxisomes, and Beta-Oxidation
Fat can be oxidized in the mitochondria and the peroxisomes of cells, the majority of this oxidation occurring in skeletal muscle cells and the liver. PPARalpha activation by sesamin increases fat oxidation in mitochondria and peroxisomes by increasing the expression of enzymes involved in beta-oxidation of fatty acids [9].

Of vital important, Sesamin increases the expression of the mitochondrial enzyme carnitine palmitoyl transferase (CPT)[9]. CPT, the rate-limiting enzyme in beta-oxidation of fatty acids in skeletal muscle and liver cell mitochondria, is found on the outer membrane of mitochondria and carries fatty acids across the membrane into the mitochondria by binding to them. Increasing the expression of CPT will allow more fatty acids to be transported into the mitochondria where they can be oxidized.

Sesamin's ability to cause an increase in fatty acid oxidation in both the mitochondria and peroxisomes is important because mitochondria can only oxidize short-chain to long-chain-fatty-acids while peroxisomes can shorten fatty acids of all lengths, including very-long-chain-fatty-acids (VLCFA). As its name suggests, Peroxisome Proliferator-Activator Receptor cause the creation of additional peroxisomes. More peroxisomes means more fat can be oxidized.

PPARalpha activation also increases uncoupling-proteins (UCPs). UCPs decrease the efficiency of mitochondria, which means an increase in UCPs would increase the calories needed to produce the same amount of energy as before, this is known as "calorie wasting." "Wasting" calories would lead to a greater caloric expenditure and therefore fat loss.

Through increasing the expression of the enzymes involved in beta-oxidation and increasing UCPs, PPARalpha activation by sesamin will increase the rate and capacity at which cells can burn fat.

Sesamin and Lipogenesis
In addition to increasing the oxidation of fat, Sesamin supplementation has also been shown to decrease lipogenesis (fat storage) by decreasing lipogenic enzymes in the liver. Sesamin has been shown to decrease lipogenic the gene expression of sterol regulatory element binding protein-1 (SREBP-1), acetyl-CoA carboxylase, and fatty acid synthase, among other lipogenic enzymes [10], which means less fat is esterifized in the liver and therefore less fat is stored in adipose tissue (fat cells). So Sesamin works in two ways to make you lean (and keep you lean): increasing fat oxidation and decreasing fat storage.

Sesamin and Ketogenesis
Ketogenesis occurs when fatty acid oxidation is increased to a point where the liver cannot metabolize off the fatty acids for energy. Excess acetyl-CoA (which can be created from fat, glucose, or amino acid metabolism) is converted to ketones in the liver and released into the bloodstream to be used by other tissues (specifically the brain). Ketogenesis is very important during low carb diets because the brain cannot use fatty acids for fuel, it can only use glucose. When glucose is low, the brain will turn to ketones for its energy. Sesamin has been shown to increase ketone production (11). Increasing ketone production should have protein-sparing effect as less amino acids will be needed to create ketones. This means your muscle mass will be spared while dieting.

Health Benefits of Sesamin
In addition to increasing fat oxidation and decreasing lipogensis, Sesamin supplementation also has many health benefits. Sesamin has been shown to be antihypertensive [3], an antioxidant itself and increase the recycling of vitamin E [4], provide liver protection against alcohol and improve liver function [5], decrease cholesterol levels [6], while increasing high density lipoprotein (HDL aka "good cholesterol") levels [7], and is an anti-inflammatory [8]. These health benefits alone make Sesamin supplementation a wise decision.

Sesamin "Point-Blank" Summary
Sesamin supplementation will prime your body to oxidize fat and not store it. Sesamine supplementation should also help spare muscle mass while dieting and has MANY positive health benefits.

Anon have you personally tried using sesamin? i am going to pick some up that is sold by axis. theres not only has sesamin but also includes EFA's

no, havent tried it but i'm seriously thinking about it now

I have used several kinds including the AXIS. Right now im using the Controled Labs Version called SesaGlow, Works just as good. This stack is what i got going on right now for keeping fat gains low on my bulk.

Sesamin (SesaGlow)at 4 grams a day
CLA (PrimaForce)at 9 Grams a day
Fish oil 7 grams a day
Lean Green (PrimaForce) 6 pills a day.

Works GREAT!

I use Sesamin as a staple in my diet now as the price as seem to drop in the past year or so.

Yes Sesamin is now one of my daily supplements as well. Sesamax by axio is a good product, along with Sesapure by Anafit. After using for 6 weeks I did appear leaner. Also another benefit that doesn't get as much attention is Sesamin's effect on liver health. I noticed this drastically while drinking...take 2 sesamin pills before going out and 2 once the night is over and your hangover will be drasticalyl reduced/gone.
Just my .02

Yea, i have noticed this works as well. I dont drink too much but when i do i dont get effect as much as some of my friends that dont workout take sups.
