Blood lipids tend to worsen with age due to declining liver function and LDL receptor activity. The single most important action: request an NMR lipoprofile test from your doctor to differentiate LDL particle sizes - not just total cholesterol. Small LDL particles (LDLC) pose the greatest heart disease risk. While hit cardio shows the best results for lowering LDL, strength training remains crucial for most people to build metabolic capacity first.
Episode Overview
This episode dives deep into understanding and improving cholesterol levels and blood lipids, particularly as we age. The hosts discuss why standard cholesterol tests don't tell the full story and emphasize the importance of getting advanced testing that shows LDL particle size. They cover the hierarchy of interventions - from appropriate exercise selection to dietary changes (reducing saturated fats, increasing fiber) to powerful supplements like red yeast rice extract. A major theme is balancing what research shows works best (like HIIT cardio for LDL) with what's actually appropriate for individual fitness levels and long-term sustainability.
Key Insights
Standard cholesterol tests miss critical information
Total cholesterol and basic HDL/LDL numbers don't tell the full story. The size and type of LDL particles matter more than the total amount. Small, dense LDL particles (LDLC) are significantly more dangerous for heart disease risk than large LDL particles. You need to specifically request an NMR lipoprofile test to get this particle differentiation.
Blood lipids worsen naturally with age
As we get older, liver function changes and LDL receptor activity decreases, meaning LDL circulates in the blood longer rather than getting utilized. This is why cholesterol levels tend to climb in midlife even if diet and exercise habits haven't changed. Genetics also play a major role - some people are highly sensitive to dietary changes while others aren't.
Exercise type matters, but appropriateness matters more
While HIIT cardio shows the best results for improving LDL levels in research, it's inappropriate for most deconditioned people over 50. Strength training should be the foundation first, building muscle and metabolic capacity. Low-risk cardio like elliptical or biking can be gradually introduced before progressing to higher-intensity intervals over months.
Saturated fat response is highly individual
About 20% of people (a significant minority) are highly responsive to saturated fat intake - it dramatically affects their blood lipids. For these individuals, replacing saturated fats with olive oil, nuts, and grass-fed/grass-finished meat makes a substantial difference. The other 80% see minimal impact from saturated fat changes, making this highly genetic and individual.
Fiber acts as a cholesterol cleanup system
Increasing dietary fiber, particularly supplemental psyllium husk, helps bind bile acids and increase LDL receptor activity. This helps your body better utilize cholesterol and sweep excess out of the system. Fiber also helps remove microplastics and other toxins, acting as a natural cleaning mechanism.
Red yeast rice is a natural statin with proven results
Red yeast rice extract contains monacolin K, which is chemically identical to lovastatin (a pharmaceutical statin). It shows measurable improvements in blood lipids and can be purchased as a supplement. One of the hosts dropped total cholesterol from 280 to 200 using it, demonstrating its effectiveness for genetically predisposed individuals.
The new protein recommendations are a game-changer
The USDA flipped the food pyramid and doubled protein recommendations from 0.8g to 1.2-1.6g per kilogram of body weight. For a 200lb person, this means going from 72g to 140g of protein daily. This change supports muscle metabolism and overall health, though optimal levels for active individuals building muscle are even higher (around 200g for that same 200lb person).
Notable Quotes
"Unless it's really really high, total cholesterol doesn't say a ton. HDL and LDL will tell us more and then you can look at the type of LDL which will tell you even more."
"Calorie deficit fixes a lot. That's why you'll get those carnivore diet people - 'Look at my blood lipids, how much better they got. Saturated fat's not bad.' Lower calories. You went in a massive deficit. That made a big difference."
"Being weak will predict mortality better than lipids that don't look so great. A strength test is actually one of the best predictors of all cause mortality."
"When I fall off the wagon of consistency and making my meals, the first thing that happens is protein automatically gets cut almost in half when I just eat whatever I feel."
"The difference between eating 140 grams of protein and eating 200 grams - 140 is great, it's fine, there's nothing wrong, it's actually good. But if you go to 200, the difference you'll see in muscle performance and recovery is astounding."
Action Items
-
1
Request advanced cholesterol testing
Next time you get blood work, specifically ask your doctor for an NMR lipoprofile test that differentiates LDL particle sizes. Don't settle for just total cholesterol, HDL, and LDL numbers - you need to know if you have small dense LDL particles (LDLC) which are the most dangerous type.

2
Build strength foundation before adding intense cardio
If you're over 50 and deconditioned, prioritize strength training 3-4x per week for 30-40 minutes. After 1-2 months of building a base, add 10-12 minutes of low-risk cardio (elliptical or bike) with brief intensity bursts at the end of strength sessions, 2-3x per week maximum. Only progress to true HIIT once you've built adequate fitness.

3
Test your saturated fat sensitivity
If your blood lipids are elevated despite healthy habits, try replacing saturated fats with olive oil and nuts for 8-12 weeks, then retest. Switch to grass-fed, grass-finished meat (like from Butcher Box) which has a better fatty acid profile. About 20% of people will see dramatic improvements from this change alone.

4
Increase protein to match new recommendations and add fiber
Aim for 1.2-1.6g of protein per kilogram of body weight (140g for a 200lb person) as the new baseline, going higher (200g) if actively building muscle. Add supplemental psyllium husk fiber to help bind bile acids, increase LDL receptor activity, and sweep cholesterol from your system. Consider citrus bergamot or red yeast rice extract if dietary changes aren't enough.
