  • Dr. Seyfried also has a conversational video talking about the paper https://www.youtube.com/watch?v=Pl5Nt3WrV5E

    summerizer

    In this video, Professor Seyfried discusses his recent paper that challenges long-standing assumptions in cancer treatment, specifically focusing on the Warburg hypothesis. He argues that many contemporary theories about cancer are based on misinterpretations of data from influential scientists like Otto Warburg and Sydney Weinhouse. Seyfried emphasizes that cancer is primarily a metabolic disease, driven by energy dysregulation instead of traditional genetic mutations. He introduces new insights into the role of mitochondrial function and the necessity of fermentable fuels like glucose and glutamine in cancer cell metabolism.

    Key Points

    Cancer Misunderstandings

    Professor Seyfried outlines how modern cancer treatment theories derive from incorrect interpretations of ancient data, particularly misrepresenting the energy metabolism of cancer cells. He argues that this has led the cancer research field astray for decades.

    Warburg Hypothesis Re-evaluated

    Seyfried discusses the Warburg hypothesis, which posited cancer as a disorder of energy metabolism due to insufficient oxidative phosphorylation. He explains how earlier interpretations of data failed to acknowledge other forms of ATP production in cancer cells.

    Oxygen Consumption vs ATP Production

    The video highlights Seyfried’s findings that oxygen consumption does not accurately correlate with ATP production in cancer cells, as opposed to normal cells where oxygen consumption is an effective marker. This distinction is crucial for understanding cancer metabolism.

    Mitigating Cancer Growth with Fuel Restrictions

    Seyfried suggests a paradigm shift in cancer treatment—removing glucose and glutamine as energy sources—since these fuels drive cancer cell growth. He proposes ketogenic metabolic therapy as a more viable approach for managing cancer.

    Mitochondrial Function in Cancer

    The discussion emphasizes that cancer cells exhibit mitochondrial dysfunction, leading to altered energy production mechanisms and excessive lactic acid and lipid droplet accumulation. These abnormalities are signals of compromised oxidative phosphorylation capabilities.

    Demand for New Cancer Treatment Models

    Finally, Seyfried calls for a review of cancer treatment strategies based on understanding its metabolic origins rather than purely genetic approaches, asserting the need to develop management techniques that address the metabolic dysfunctions of tumors.








  • Substituting dietary saturated for monounsaturated fat impairs insulin sensitivity

    Thank you for the reference, it was a interesting read. This study has the Saturated fat group at 50% saturated fat, and 50% unsaturated fats, its not a very clean signal. I’m not sure why the SAFA group had a reduced response to a GTT, it warrants further study.

    Since the study you reference is from 2001, there are more recent studies that reference it.

    Saturated Fatty Acid Intake and Risk of Type 2 Diabetes: An Updated Systematic Review and Dose–Response Meta-Analysis of Cohort Studies

    There was evidence of publication bias among studies on dietary total SFAs and T2DM. Our results indicated no significant association between dietary total SFA and risk of T2DM.

    Some of the experimental studies support the notion that dietary fats, and SFAs in particular, are associated with the development of insulin resistance and type 2 diabetes mellitus (T2DM) (2–5). On the other hand, the majority of more recent cohort studies have indicated no association between dietary SFAs and the incidence of T2DM

    The linear dose–response meta-analysis of the main 13 studies showed no linear association between increasing intake of SFAs and T2DM risk (HR: 0.93; 95% CI: 0.84, 1.03). From 13 cohort studies regarding the association between total SFAs and T2DM risk, 7 studies (5–7, 9, 31, 33, 34) reported sufficient data for the nonlinear doseresponse analyses. There was no evidence of a U- or J-shaped association between total SFA intake and risk of T2DM (Pnonlinearity = 0.153; n = 7; Figure 3). Supplemental Figure 5 presents the results for publication bias. Overall, there was evidence of publication bias with the Egger test (P = 0.032).

    Her story in the nutritional class touches me deeply, the advice they were given is opposite of what she should be doing.

    Through the process of elimination she discovered keto wasn’t enough, and she had some level of oxalate sensitivity

    Since she spent most of her life at low or no fat, it took her a month to get her gall bladder back into shape.




  • #3 some sites don’t allow the + so you’re screwed

    Having your own domain name is great here! Plus a catch all address

    Q@starfleet.ufp

    But maybe you get spam at starfleet.ufp, so subdomains to the rescue, they NEVER get random spam, so you can have

    b.sisko@ds9.station.starfleet.ufp or any other address you want at @ds9.station.starfleet.ufp and have it go to your catchall address.

    Some email services, like fastmail, will let you automatically respond to emails to your catchall from the address they sent mail to. So you will always respond as b.sisko@ds9.station.starfleet.ufp if someone mails you at that address. its nifty. Good enough for the great link
