Now, back on topic,
for many here building muscle is not a priority however for me and a few of the male member here building muscle is important. A big hormonal factor for building muscle is testosterone (yes for us ladies as well) one dietary factor in this is fat intake.
Ladies - The ovaries produce both testosterone and estrogen. testosterone is released into your bloodstream by the ovaries and adrenal glands.
PUFA (Polyunsaturated fatty acids) like canola oil, soy bean oil, sunflower seed oil etc suppress testosterone production as well as suppressing thyroid hormones.
PUFA have long sensitive carbon-carbon chains in their structure. This makes the fatty-acids very unstable when in contact with oxygen, heat, and light, causing them to literally go rancid inside the body through a process called “lipid peroxidation”. This creating free radical and eventually oxidative damage in the cells.
The suppression of thyroid hormone is not good for your weight loss efforts.
