Full Description
In this episode of the Physical Activity Researcher Podcast, Dr. Olli Tikkanen continues his insightful conversation with Dr. Richie Kirwan, a lecturer in nutrition and exercise physiology at Liverpool John Moores University. Dr. Kirwan delves into the intricate relationship between muscle mass, blood lipids, and cardiovascular health.
Dr. Kirwan explains the significance of ApoB, a protein that plays a crucial role in carrying cholesterol through the bloodstream. He discusses how resistance exercise can influence ApoB levels and improve the overall lipid profile, highlighting early research findings that suggest a positive impact of increased muscle mass on cardiovascular risk factors.
The episode explores how resistance exercise might lower ApoB by affecting molecules like PCSK9, which is involved in LDL cholesterol recycling. Dr. Kirwan emphasizes the need for further research to fully understand these mechanisms and their practical implications for improving heart health.
Dr. Kirwan also addresses the broader impact of muscle mass and strength on cardiometabolic health, suggesting that higher levels of physical activity and muscle mass are associated with better health outcomes. He encourages listeners to maintain an active lifestyle, combining both cardiovascular and resistance exercises for optimal benefits.
Join us to learn more about the crucial role of muscle mass in lipid metabolism and cardiovascular health, and gain practical advice on incorporating strength training into your fitness routine for long-term heart health benefits.

It could be interesting look at the MR study and its relation to lipid-energy-model. Smaller vldl could just be faster delivery mechanism of the LEM. LEM and LMHR hyper-response might be tied to those genes could suggest there is pleiotropy on those gene's impact on APOB studies and mortality/ASCVD.
Exercise is about increasing blood flow. Lipids are NOT implicated in CVD. Nobody can explain HOW cholesterol creates plaques. But many people states these associations. Imthink you need to read dr Gregory Sloop on CVD and blood flow, he has a scientific explanation like no one. Lipids improve with exercise but this is an indirect benefit which i necer really care.
I'm 41 years old. I had an MR Venography of the abdomen and pelvis with and without contrast for POTS (Postural Othostatic Tachycardia Syndrome) and chronic venous insufficiency in the legs (verified by ultrasounds showing reflux).
Under liver, they noted "Mild hepatic steatosis. Multiple hepatic hemangiomas." Is there something that I can do to head off that hepatic steatosis? I've been active for all of my life, never drank, never smoked, never took drugs, etc. I've lifted weights and done cardio since my early teenage years. Obviously, eat lots of protein, most of which is baked chicken and such. I'm very muscular for being only 5'8 and 160 pounds. Any thoughts on how to keep these fat levels in my body down?
Adjust Diet: Focus on reducing refined carbs and increase intake of healthy fats like omega-3s and unsaturated fats.
Maintain Activity: Continue with cardio and strength training, and consider adding more daily physical activity or HIIT.
Monitor Body Fat: Keep an eye on body fat percentage, especially around the abdomen, and adjust diet or exercise as needed.
Regular Check-Ups: Schedule follow-up tests with your healthcare provider to monitor liver health and fat levels.
Consult Experts: Consider seeing a hepatologist or dietitian for personalized advice and be cautious with medications or supplements.

what is the reason for not calling HDL a good cholesterol? Is it because it is not actually cholesterol?
Without being an expert on this, I would assume giving label "good" is too simplistic. Human body and it's physiological processes are usually pretty complex.
