The much-maligned saturated fats—which Americans are trying to avoid—are not the cause of our modern diseases. In fact, they play many important roles in the body chemistry:
1. Saturated fatty acids constitute at least 50% of the cell membranes. They are what gives our cells necessary stiffness and integrity.
2. They play a vital role in the health of our bones. For calcium to be effectively incorporated into the skeletal structure, at least 50% of the dietary fats should be saturated
3. They lower Lp(a), a substance in the blood that indicates proneness to heart disease.39 They protect the liver from alcohol and other toxins, such as Tylenol
4. They enhance the immune system
5. They are needed for the proper utilization of essential fatty acids.
Elongated omega-3 fatty acids are better retained in the tissues when the diet is rich in saturated fats.
6. Saturated 18-carbon stearic acid and 16-carbon palmitic acid are the preferred foods for the heart, which is why the fat around the heart muscle is highly saturated. The heart draws on this reserve of fat in times of stress.
7. Short- and medium-chain saturated fatty acids have important antimicrobial properties. They protect us against harmful microorganisms in the digestive tract.

To add, Mozaffarin in his journal paper,if I understand correctly,stated that through his study, diet of low fat(mostly saturated)/high carb results in higher triglyceride and lower HDL,while maintaining LDL level.Whereas diet composing of high fat/low carb results in lower triglyceride level,higher HDL and lower LDL level.The lower consumption of carb may be related to the lowering of triglyceride(insulin-triglyceride production relations),what interest me the most is on the level of HDL and LDL from the total consumption of saturated fat.Will be loking for more info on cholesterol build-up in relations to saturated fat consumption.
And for a better read,might want to try read this:

4Rings:
while you're on low carb/high fat diet,how's your re-feed period?or its 24/7 low carb/high fat diet for you?Dave Palumbo, Par Deus and some other,do include a refeed period after a set timeframe to replenish glycogen level(it can go as high as 800g-1200g carbs on the refeed day).Wanna know,is it really important?As in keto diet,we're using ketones instead of glycogen as fuel source,then why do we still need to bother on replenishing glycogen?Hope you can help to shed some light on this.Thanks
