<p>PUFAs have multiple double carbon bonds which are at risk of converting to trans fat when processed at high temperatures for a substantial amount of time. SFAs do not have any double carbon bonds so they are not at risk of being converted to trans fat. MUFAs only have a single double carbon bond so the risk of converting to trans fat is very minimal.</p>

<p>An increased fat intake can improve the endogenous production of anabolic hormones and also possibly by alter muscle cell membrane functioning.</p>
<p>Women’s metabolisms are more protein- and glucose-sparing than men’s in comparison and so they preferentially oxidize fat for fuel/energy (fat is the generally preferred energy substrate). Dietary fat can also be more satiating in women than men. An increase in dietary fat can also help in greater estrogen production which is beneficial for women.</p>
<p>It is not how much testosterone per se that someone has but rather the amount of androgen receptors which predicts how much muscle mass someone can gain. An individual can have as much testosterone as someone else, but if the other person has more androgen receptors, then that individual likely has a greater propensity for building for muscle. The other person may also have a stronger affinity for the receptor, a higher amount of unbound testosterone, or less antagonistic activity on the androgen receptor.</p>
<p>AAS users do not benefit from anabolic hormonal benefits that increased fat intake provides to natural trainees as they are already providing themselves with amounts of exogenous testosterone that are above and beyond what the body can produce naturally.</p>

<p>Chylomicrons are lipoproteins that transport dietary fat metabolites after their digestion and absorption. They are effectively taxi drivers for fats.</p>
<p>No. The small intestine can digest up to 600 g of triacylglycerols with 95% efficiency.</p>
<p>Short- and medium-chain fatty acids are transported directly to the liver from the small intestine.<br><br>Long-chain fatty acids must first be packaged into chylomicrons before being transported to the tissues that need them (e.g., muscle and adipose tissue).</p>

<p>BF% is generally determined by how full a person’s adipocytes are, not the number of adipocytes. After adolescence, the number of adipocytes a person has stays relatively constant and would only materially increase if the person experienced significant fat gain (adipogenesis).</p>

<p>Testosterone acts on androgen receptors, and this information is passed to the muscle cell cores which give instructions to synthesize muscle proteins (genomic effect). Testosterone also aids in the formation of new satellite cells which contribute to myonuclear addition. Without myonuclear addition (increase in muscle cell nuclei) muscle growth is inherently limited as each nucelus as a limited transcriptional capacity.</p>

<p>liver<br>lipoproteins</p>
<p>LDL cholesterol is seen as bad due to the capacity of its load of cholesterol and other lipids to clog up your blood vessels. However, LDLs are vital for lipid metabolism in the body. LDLs are just lipid transporters in the body so they are not inherently unhealthy. </p>

<p><span style="color: rgb(255, 255, 255)">If your diet doesn’t contain much cholesterol, your intestines will increase their absorption to compensate. If that is not enough, your body will produce its own cholesterol. If your diet contains excessive amounts of cholesterol: (i) your body will reduce its absorption, (ii) the liver will decrease its synthesis, and (iii) the cholesterol excretion rate increases. Therefore, for most people, how much cholesterol you eat doesn’t have much effect on how much cholesterol in your blood.</span></p><p></p>
