NOTICE OF DISCLOSURE: http://cmp.ly/3
In Episode 11 of “Jimmy Moore Presents: Ask The Low-Carb Experts,” we welcome nutritional health researcher and associate professor of kinesiology at the University of Connecticut Dr. Jeff Volek. He is widely regarded and respected as one of the world’s renowned experts in exercise, nutrition, weight loss and low-carb diets today. He is the author of a number of popular books addressing these subjects, including Men’s Health TNT Diet, co-author of The New Atkins For A New You with Dr. Stephen Phinney and Dr. Eric Westman, The Art and Science of Low Carbohydrate Living in 2011 with Dr. Phinney and the forthcoming The Art and Science of Low Carbohydrate Performance (which I’ll be sharing more about very soon!).
I interviewed Dr. Volek a few years back in Episode 236 of “The Livin’ La Vida Low-Carb Show” podcast and I’ve personally heard him lecture at various obesity conferences over the years. He will be joining us on The 5th Annual Low-Carb Cruise in May 2012, but we were pleased to have him with us in this episode to discuss a subject he has studied thoroughly over the past few years. Saturated fat is arguably the most misunderstood and maligned real food in the history of mankind and Dr. Volek is THE expert who can answer any and all questions about how it impacts you metabolically. We were privileged to have him here addressing this very important topic and we appreciated having the expertise of Dr. Jeff Volek joining us on ATLCX answering listener questions about anything and everything to do with saturated health in EPISODE 11 on March 29, 2012.
Listen to Dr. Jeff Volek address the topic “Saturated Fat Is Good For You?”: Learn why saturated fat was vilified in Gary Taubes’ books Nutrients you consume in food “don’t act in isolation” You can’t just talk about saturated fat without carbohydrate too Saturated fats are “non-essential” and make it on its own Carbohydrates get converted into saturated fat in the body The consistent message that saturated fat is “unhealthy” His November 2007 study in Lipids on saturated fat He thought he was going to “change the world” with his research Low-carbers who ate more saturated fat had lower blood saturated fat Low saturated fat dieters had more blood saturated fat His follow-up study that fed the subjects isocalorically The same results happened with blood saturated fat levels A “well-formulated low-carb diet” uses fat for fuel Low-carb inhibits saturated fat and increases burned saturated fat The unpublished research that measures saturated fat in tissues There’s less accumulation of saturated fat because it’s being used Saturated fat can’t be harmful if it’s turning to CO2 and water If it’s possible to get too much saturated fat in your diet Determining how much carbohydrate is “too much” for you is key Accumulation of saturated fat is a manifestation of too many carbs High blood saturates increase risk of heart disease and diabetes Cholesterol is probably not worth looking at for heart health The primary function of saturated fat on a low-carb diet is fuel A low-carb diet is quite effective at raising HDL cholesterol It’s extremely difficult to raise this “stubborn lipoprotein” The study comparing eggs vs. egg substitutes observing HDL Dietary cholesterol may be key part of improving lipid numbers There’s a strong genetic component associated with HDL Exercise and fish oil are “fairly weak” at raising HDL Low-carb diets are more consistent at raising HDL than anything Whether saturated fat is good for you or just not bad If you’re eating high-carb, then you should cut saturated fat On low-carb, there’s no concern consuming saturated fat Eating “copious amounts” of saturated fat is essential for fuel Saturated fat is satisfying, satiating and sustainable Burning fat for fuel gives you “quite the reserve” of fuel If you miss a meal when fat-adapted, you’re “not in a crisis” Dave Aspry’s Bulletproof Coffee with grass-fed butter Monounsaturated fat would be great fats on a low-carb diet, too Fat in animal products have as much or more monounsaturated fat From evolutionary perspective, we should mimic fat content in nature Mixing saturated with monounsaturated fat is ideal You can get a high-oleic safflower oil that’s lower in omega-6 If there is a distinction between the kinds of carbohydrates Quality of carbohydrates is important on a variety of levels But you can’t ignore the quantity which is “more important” There are people who can tolerate a higher carbohydrate intake Be careful consuming fructose (which is “highly lipogenic”) Consume high-water content fruits like berries instead There are people who promote low-GI diets that don’t promote low-carb There’s evidence that saturated fat in the body is “harmful” Not “you are what you eat” but “you are what you save from what you eat” Saturated fat is not benign if it accumulates in the body Dietary saturated fat on a low-carb diet is indeed benign Dietary carbs have a more dominant role in saturated fat in the body Not sure if there is a connection between low-carb and hair loss Well-formulated low-carb diets are anti-inflammatory The impact of saturated fat on Lp(a) and LDL particle size External changes tend to have “little impact” on Lp(a) He’s seen a positive change in Lp(a) on low-carb diets LDL cholesterol has many different sizes (small, medium, large) Research implicates that small, dense LDL particle are the worst Low-carb “very very consistently” increases the LDL particle size It’s also “very intimately tied to the triglyceride levels” The NMR Lipoprofile or VAP Test will measure LDL particles If consuming saturated fat like coconut oil increases body heat The thermogenic effect usually happens with alcohol and protein Fat tends to have lowest thermogenic effect of the macronutrients The medium chain triglycerides in coconut oil may be the culprit The “metabolic advantage” of low-carb diets needs to be studied Whether a high saturated fat diet can lower arterial plaque There’s no research that has been conducted on this question It’s “questionable” drugs or low-fat regresses arterial plaque If you have plaque now, a low-carb diet would be “reasonable” His research looking at vascular function on a low-carb diet Whether saturated fat can become rancid or not Saturated fat is “fairly stable” compared with polyunsaturated fat Flax seed oil needs to be refrigerated and away from light Why the body converts excess protein to make glucose There are cells in the body with “an obligate need for glucose” If you eat a ketogenic low-carb diet, then ketones can fuel brain Over half the brain’s energy supply can come from ketone bodies Requirement for gluconeogenesis goes way down when keto-adapted There’s no concern that you break down muscle mass on low-carb High-protein diet can be “counterproductive” from GNG/insulin effect You won’t reach the level of ketosis needed on “halfway low-carb” What are the “healthy fats” promoted by the health “experts” On a low-fat diet, you have to eat the polyunsaturated fats On a low-carbohydrate diet, 65%+ fat is consumed Healthy fats on low-carb are saturated and monounsaturated fats Why polyunsaturated fats on a low-carb diet are a bad idea Avoiding soybean, safflower, corn and peanut oils is best Choose olive oil, coconut oil, and butter when eating low-carb If you can afford it, go with grass-fed meats when possible There’s not a lot of data on toxin levels with feeding methods Particle size tests “are not routinely done” in doctor’s offices The various technologies used to measure cholesterol particles His research has seen “trends are very consistent” on all tests A good surrogate for LDL particle size is triglyceride/HDL ratio How to convince engineers about the healthy saturated fat message Meta-analysis research looking at saturated fat and heart disease America has reduced saturated fat and replaced with carbohydrate This has INCREASED the risk for coronary heart disease There are individual diets that need to match up with genomes The role that microbiota in the gut are playing in obesity Looking at how people respond to various levels of carbohydrates Whether reducing saturated fat and calories will lower body fat There’s no reason to lower saturated fat in your diet There’s no reason you can’t gain weight on low-carb with excess calories What role saturated fat plays in lowering T3 levels He’s seen “no change in thyroid levels” in his low-carb studies 10: ‘All Things Thyroid (Thyroid 101)’ | Chris Kresser His research hasn’t looked at the full thyroid panel The composition of cell membranes is “very important” Having the right proportion of fats in the cells is critical Convincing evidence that fats play a role in insulin sensitivity Dietary saturated fat and muscle membrane saturated fat not same He wrote The Art And Science book for physicians
