Environmental Factors Trump Genetics in Obesity Epidemic
TL;DR
- Framing obesity primarily as a genetic disease is preposterous and insulting, as environmental factors and lifestyle choices have dramatically shifted societal obesity rates over recent decades, not genetics.
- Attributing over 50% of obesity to genetics and only 15% to diet and exercise is a harmful narrative that removes patient agency and promotes medication-first approaches.
- Resistance training is crucial for body recomposition by increasing metabolically healthy tissue, thereby raising resting metabolic rate, which is a significant factor in caloric expenditure.
- Prioritizing protein intake in midlife is essential not only for muscle building but also for satiety, compensating for declining natural GLP-1 levels and supporting appetite regulation.
- While genetic predispositions exist, the modern obesogenic environment, characterized by readily available processed foods, rancid oils, and endocrine-disrupting chemicals, plays a far more significant role for most individuals.
- Medications like Ozempic can be helpful tools to exit an obese state, but they do not replace the fundamental need for developing life skills in eating and movement.
- Epigenetic changes, as observed in historical famines, demonstrate how severe environmental stress can create multi-generational predispositions to obesity, highlighting the impact of external factors.
Deep Dive
The prevailing narrative that obesity is primarily a genetic disease is scientifically questionable and disempowering, particularly for women in midlife. While genetic predispositions exist, they are significantly outweighed by environmental factors and lifestyle choices, making diet and exercise the primary tools for managing weight and health, not just medication.
The argument that obesity is a genetic "first disease" is flawed because it implies a passive role for the individual, suggesting that medication is the sole or primary solution and that lifestyle interventions are futile. This perspective ignores historical data showing lower obesity rates in societies with less environmental and dietary "obesogenicity." Genetics do not change significantly over short periods, but the modern environment--characterized by readily available processed foods, rapid consumption, and exposure to endocrine-disrupting chemicals--has created an "obesogenic" landscape. This environment interacts with our genes epigenetically, increasing the propensity for weight gain. For instance, historical famines have demonstrated multi-generational epigenetic shifts that predispose offspring to store more adipose tissue.
Furthermore, framing obesity as purely genetic removes agency from individuals, particularly women in perimenopause and menopause, who may already be experiencing hormonal shifts that affect metabolism and body composition. While these hormonal changes are real, they do not negate the fundamental principles of energy balance. The emphasis should remain on building metabolically healthy tissue through resistance training, which increases resting metabolic rate, and prioritizing protein intake for satiety and muscle preservation. These lifestyle habits are crucial for long-term health and should be the foundation, even when pharmacological aids like GLP-1 agonists are used. The "hack" mentality that seeks shortcuts through medication without addressing fundamental lifestyle habits is ultimately unsustainable and fails to build the necessary life skills for health management.
Action Items
- Audit messaging: Analyze 3-5 online posts promoting genetic causes of obesity to identify and counter misinformation.
- Create educational content: Develop 2-3 short explainers on epigenetics and environmental factors influencing weight for public dissemination.
- Implement resistance training protocol: For 5-10 clients, integrate resistance training to build muscle and increase resting metabolic rate.
- Track protein intake: For 3-5 individuals, monitor daily protein consumption to ensure adequate intake for satiety and muscle maintenance.
- Evaluate personal environment: Assess personal living and eating environments for 2-3 obesogenic factors and identify mitigation strategies.
Key Quotes
"if it's a genetic disease well then she can't do anything right she just has to take the medication but she can sit on the couch and eat all the foods that she wants and there's no solution for that there's nothing that she can actually do because the medication is the first and primary mode of treatment so i'm just going to call bullshit here okay"
Dr. Stephanie argues that framing obesity as a purely genetic disease is problematic because it implies a lack of personal agency. She believes this perspective suggests that individuals have no control over their health and must rely solely on medication, which she finds to be a "bullshit" notion.
"however this idea that obesity is a genetic first disease is not only preposterous it's also insulting all you have to do is look at society 20 years 30 years 50 years ago and you know 100 years ago if you want to put a little bit more time around it and you know that the societies were not generally obese they were typically quite not you might make the argument of fit but like there was it wasn't an obese a obesogenic society people were not obese there"
Dr. Stephanie asserts that the notion of obesity being primarily genetic is both absurd and offensive. She supports this by pointing to historical societal data, indicating that obesity was not as prevalent in the past, suggesting that environmental factors, not genetics, are more likely culprits for the current "obesogenic society."
"what has changed is the epigenetics the environment in which our genes live in right so we live in this like wally that you know the disney movie wally we live in this sort of wally type of world now where everything is available to us at our fingertips right we can order food and it's at our door in 30 minutes we can order whatever we want from amazon or whatever whatever right we go to fast food and we have fast food on our plate within you know minutes"
Dr. Stephanie explains that while genetics are static, epigenetics--the environment influencing gene expression--have changed drastically. She likens our current environment to the world in the movie WALL-E, where convenience and immediate access to food and goods have created an environment that promotes less healthy lifestyles.
"but with obesity it's a little different if we look at obesity as a genetic disease then but we are essentially saying that this can the first line of treatment for it is medication aka glp1s gip1s you know the ozempics the mounjaros the trulicity etc the other problem which is related to a medication first approach is that we are taking power away from the patient to actually affect and control her destiny right"
Dr. Stephanie contends that treating obesity as a genetic disease implies medication is the primary solution, like with conditions such as sickle cell anemia. She argues that this "medication-first" approach strips individuals of their power to influence their health outcomes through their own actions.
"i don't care about i mean i care about feelings but in this case i don't care about feelings this is the truth you can use the pharmacology to help you get out of a bad situation of course you can but you need to develop life skills and lifestyle habits"
Dr. Stephanie states that while she acknowledges feelings, her focus is on the truth regarding obesity. She believes that while medications can be helpful tools to escape difficult health situations, they are not a substitute for developing essential life skills and sustainable lifestyle habits.
"the paradox of life is that right it's like nothing worth having is usually easy and if it you know you've given up something something has been sacrificed in order for it to be easy and this is the hack part of biohacking that just drives me insane you cannot shortcut like ozempic is not going to lift the weights for you ozempic is not going to build your plate for you it's going to make you not want to eat a lot of things on your plate and this is why you absolutely must give your muscles a mechanical stimulus in order to prevent yourself from losing the muscle mass that we that it's been shown shown to do if you're not if you're not weight training and prioritizing protein"
Dr. Stephanie highlights the paradox that valuable achievements are rarely easy, and shortcuts often involve sacrifice. She criticizes the "biohacking" mentality that seeks to bypass effort, emphasizing that medications like Ozempic cannot replace the necessity of physical activity, such as weight training, for muscle maintenance and overall health.
