Here’s a question I’m looking at via a comparison of the following diets:
1. Optimal Nutrition (Homo Optimus by Jan Kwasniewski)2. Atkins3. The Schwarzbein Principle II (let’s say TSP)4. Ron Rosedale’s recs (metabolic medicine doc whose transcribed talk on”Insulin and its Metabolic Effects” is on Mercola’s site)
All are in the same ballpark as far as recognizing the need for healthyfats including saturated fats, and all recommend relatively low-carbs. Thediscrepancy I’m trying to tease out and explore is the issue of how muchsat fat, for whom, and when.
The ON diet recs high sat fat and says that people shift over tofat-burning usually fairly quickly, younger people especially. His recsseem simpler than the others, at least as they’re laid out in his book,whereas in his clinic he individualizes more.
Atkins also says you can plunge right in with the fat rec, as far as I’ve seen.
TSP, by comparison, outlines four different metabolic types. She uses theparameters of insulin sensitivity/resistance and adrenal health/burnout, sothose combine for 4 different types. While she says we need sat fat in thediet, she recs that the two insulin resistant types minimize the amount ofsat fat during the transition phase of the program.
She stresses that for some people, that transition stage can take even upto a few years to go through before the metabolism has shifted tofat-burning and the sat fat can finally be utilized for energy and not bestored as fat. (ON also describes this as a rebuilding phase, but doesn’tdiscuss the time frame).
So for those who are already insulin resistant, TSP says it would be astress on the metabolism that is already storing fat, to be dealing withmore sat fat at that time. Then once the metabolic damage has healed, theywould increase their sat fats up to a maintenance level.
TSP outlines a therapeutic diet for that particular transition period tohelp take people from insulin resistance back to insulin sensitivity, andthat diet is quite low in sat fat although it contains mono and good PUFAs(I don’t agree completely with her choices of veg oils, but that’s not theissue here).
So her approach is markedly different from the other two which seem to sayjust go ahead with the sat fats and everything will come out in the wash.
Ron Rosedale takes the same approach as TSP, limiting sat fat while aperson is insulin resistant. Some quotes:
hyperinsulinemic or overweight, I want them on a low saturated fat diet.Because most of the fat they are storing is saturated fat. When theirinsulin goes down and they are able to start releasing triglycerides toburn as fat, what they are going to be releasing mostly is saturated fat.So you don’t want to take anymore orally.<<
from the moment you were born, but we don’t, we are dealing with animbalance here that we are trying to correct as rapidly as we can.You have plenty of saturated fat. Most of us here have enough saturated fatto last the rest of our life. Truthfully. Your cell membranes require abalance of saturated and poly-unsaturated fat, and it is that balance thatdetermines the fluidity. As I mentioned, your cells can become over-fluidif they don’t have any saturated fat.Saturated fat is a hard fat. We can get the fats from foods to come mostlyfrom nuts. Nuts are a great food because it is mostly mono-unsaturated.Your primary energy source ideally would come mostly from mono-unsaturatedfat. It’s a good compromise. It is not an essential fat, but it is a morefluid fat. Your body can utilize it very well as an energy source.<<
I’m tending to go with him and TSP on this issue, even according to ON’smessage that you shouldn’t “mix fuels” (high [tag]carbs[/tag] with high fat). Becausewhen you’re insulin resistant, even if you’ve started a low-carb diet, yourmetabolic processes are still geared toward sugar burning not fat burning.So that’s a special condition that seems to call for a special temporarymeasure. And if temporary for you really means a year or two, as opposed toa week or two for a youngster, this could be a significant issue.
I can see going easy on the sat fat temporarily, but also it occurs to methat eating a lot of fats is what mainly helps people overcome their carbcravings, and it’s hard to get the amount of fats that will accomplish thatwithout much sat fat. Maybe a person in that situation can do the high fatsfor a few days or a week at first just to get over that hump, and then cutback for the duration of their transition period.
Then there’s the question of the insulin resistant person who isunderweight, how do they prevent further weight loss with this approach.My guess is that TSP would say that the weight isn’t an issue at thatstage, that the metabolism has to be healed first before the weight cannormalize.
I think the main overriding issue here is finding out what are the specialneeds of a damaged metabolism. Looking at traditional diets may not beenough of a guide in this area, since traditional people were maintainingtheir already healthy metabolism, not challenged to heal one that’s beendamaged over years. So how do we get from where we are now, to a baselinelevel of health that then puts our dietary needs more on a par with theirs.
I may not be able to respond to many replies here, but I’d reallyappreciate some discussion on this.
