Hi Susan,
amazing that this is what works for you.But then you have very complicated adrenal problems..... :(

If you are lurking here, older, bit obese, too high bloodglucose and cholesterol then I hope that you do some serious research yourself and talk to a dokter before you adopt Susans way of coping with your health problems.Moving as little as possible and eating saturated fat is the worst advice possible for a member of the obesity tsunami with T2.At least that is what science thinks at the moment.Which may change tomorrow....

This is from Mary Enig, PhD, lipids researcher:


All the articles are about 20 years old.We have newer insights today. Pubmed does not know a "Mary Enig" .There is only 1 comment of her in Pubmed which is a comment on the only article of Gary Taubes.....


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:


There are no essential saturated fats, if your body NEEDS them they can be made from all kind of things.

BUT
if you are obese than your body tries to save your life but pulling all those Mc Burgers from your blood and stores it in pure panic in all kinds of places where it should not be.


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.


Ok
the heart runs on fat, like your other muscles.That fat is stored in the muscle and does no harm to the bloodflow.Athletes, long distance runners, nomadic tribes in Africa are very lean, very active AND have a lot of fat in their muscles.It is the natural energy store.Evolution designed us in that way.Those people can run/hunt for days without eating.They USE the energy that their body stored for them.Their fat is burned to provide the energy.No heart problems...

BUT
if you are obes and in a constant overfed state than fat clogs the heart arteries....Which is something different.If you are physical active and not obese than the fat in your muscles, heart and legs, is BURNED.If you are overfed than the fuel store of fat is never used and cases trouble.

Short- and medium-chain saturated fatty acids have important antimicrobial properties. They protect us against harmful microorganisms in the digestive tract.

Actually i's the otherway around : good nutrition => good bacteria in your gut which both produce SCFA AND protect us from harmfull micro organisms

Here is a bit newer one :

CONCLUSIONS

Brachial artery testing revealed an inverse correlation between flow-mediated vasodilatation and intake of saturated fat.Tech speak... More butter, lard, coconut more problems with your heart .... :(

High saturated fat intake may adversely impact lipids and endothelial function during weight maintenance. As such, popular diets such as Atkins may be less advantageous for CHD risk reduction when compared to the Ornish and South Beach diets once weight loss has been achieved. The findings support additional study, especially in subjects with or at increased risk of CHD, in order to further explore the potential clinical implications of popular diets during long-term maintenance.

Comparative effects of three popular diets on lipids, endothelial function, and C-reactive protein during weight maintenance.

Although popular diets focus on weight loss and their favorable biochemical and physiological effects, fewer investigations have evaluated the biological impact of these diets during weight maintenance. To study this issue, three popular diets-Atkins, South Beach, and Ornish-were tested in a randomized and counterbalanced crossover study between January and December 2006. Participants completed each of the three 4-week isocaloric dietary intervention phases followed by a 4-week washout period. They were weighed weekly and caloric adjustments made if weight change exceeded 1 kg. At the completion of each dietary phase, 3-day food records were analyzed, fasting blood sampled, and brachial artery reactivity testing performed. Eighteen adults completed all three isocaloric dietary phases. During the South Beach and Ornish maintenance phase, there were significant reductions in low-density lipoprotein cholesterol (11.8%; P=0.01, 16.6%; P=0.0006, respectively) compared to prediet baseline. In addition, in contrast to the Atkins maintenance phase, significant reductions in low-density lipoprotein cholesterol and apolipoprotein B levels were observed after the South Beach (P=0.003, P=0.05; repeated measures analyses of variance) and Ornish maintenance phases (P=0.0004, P=0.006, repeated measures analyses of variance). Brachial artery testing revealed an inverse correlation between flow-mediated vasodilatation and intake of saturated fat (r=-0.33; P=0.016). These data suggest that during weight maintenance, less favorable biological effects are observed during a simulated, high-fat Atkins diet when compared to the South Beach and Ornish diet. The findings support additional study in subjects with visceral obesity and the metabolic syndrome, in whom an increased risk of coronary disease at baseline may be accentuated with chronic consumption of a diet that exhibits unfavorable effects on lipids and endothelial function.
