Global obesity rates are climbing at an alarming rate, with over 1 billion men and 1.11 billion women classified as overweight or obese as of 2021. China, India and the U.S. continue to account for the largest share of the world’s overweight population, each housing hundreds of millions of affected individuals.
Obesity is far more than a cosmetic concern. It’s a leading driver of metabolic disease, including Type 2 diabetes, cardiovascular disease and obesity-related cancers. The latest research sheds light on why modern lifestyles are fueling this epidemic and, more importantly, what must be done to stop it.
Current Public Health Strategies Have Failed
Public health strategies have failed to slow this crisis. Without a radical shift in understanding the root causes of metabolic dysfunction, obesity will continue to spiral out of control.
• Global obesity rates have skyrocketed over the past three decades — According to a study in The Lancet, between 1990 and 2021, obesity prevalence in men increased by an astounding 155%, while women saw a 105% increase. The trend is not slowing down. By 2050, an estimated 3.8 billion adults — more than half the global adult population — will be overweight or obese.1
• Obesity is spreading faster in developing regions than ever before — Historically, obesity was most prevalent in high-income nations like the U.S., but the most dramatic increases are now occurring in Africa and Asia. The study found that sub-Saharan Africa is expected to see a staggering 254.8% rise in overweight and obese individuals by 2050, with Nigeria alone forecasted to have 141 million affected adults.
• Some regions are already seeing obesity rates exceeding 80% of the population — Countries in Oceania, North Africa and the Middle East are experiencing the highest rates, with some surpassing an 80% obesity prevalence among adults. This suggests that, in these regions, being overweight is becoming the norm rather than the exception.
The Health and Economic Consequences of Obesity Are Devastating
In 2021 alone, obesity contributed to 3.71 million deaths and was responsible for 129 million disability-adjusted life years, a measure of lost health and productivity due to disease. This places obesity among the top global health threats, alongside smoking and high blood pressure. The Lancet study predicts that if obesity trends continue, more than 1.31 billion people worldwide will develop diabetes by 2050.2
• Obesity-related cancers are expected to surge — The study estimates that by 2070, over 2 million new cancer cases per year will be directly linked to obesity, accounting for about 7% of all cancers worldwide. This highlights the importance of addressing obesity not just as a metabolic issue, but as a central factor in cancer prevention.3
• Obesity is a multi-trillion-dollar crisis — In 2019, obesity-related health care costs ranged from $3.19 billion in low-income countries to a staggering $1.33 trillion in high-income nations. By 2035, the global economic burden of obesity is projected to reach $4 trillion, accounting for a 2.9% reduction in worldwide gross domestic product.
Childhood Obesity Is Rising Fast, Leading to Lifelong Health Risks
A separate study in The Lancet found that obesity rates among children and adolescents have also risen sharply, setting them up for a lifetime of chronic health problems.4
• Obesity-related diseases will affect future generations more severely — The earlier someone becomes obese, the longer their body is exposed to metabolic dysfunction, inflammation and hormonal imbalances. This prolonged exposure increases the likelihood of developing conditions like Type 2 diabetes, high blood pressure and even obesity-related cancers at younger ages than ever before.
• Obesity is cutting lifespans shorter across the globe — The study found that obesity is now one of the leading risk factors for premature death, even in young adulthood. The combination of metabolic dysfunction, systemic inflammation and organ strain caused by excess body fat significantly increases the risk of dying from conditions like heart disease, stroke and diabetes-related complications.
• Public health efforts have failed to curb childhood obesity — Despite decades of awareness campaigns and school-based nutrition programs, childhood obesity rates continue to rise. The study suggests that current interventions are not addressing the root causes — namely, ultraprocessed foods and a growing dependence on screen-based entertainment that discourages physical activity.
The Food Industry’s Role in the Global Obesity Epidemic
Research highlights how multinational food companies have aggressively marketed ultraprocessed foods, sugary beverages and seed oil-laden snacks to populations worldwide. These products, which are cheaper and more convenient than whole foods, have become dietary staples, fueling the obesity crisis.5
• Aggressive marketing strategies target vulnerable populations — Many of these companies specifically target children, low-income communities and developing nations with their advertising. This has led to a cultural shift where ultraprocessed foods are not just common but normalized as everyday dietary staples, despite their well-documented health risks.
• Government policies have failed to regulate unhealthy food marketing — While some countries have implemented taxes on sugary drinks and front-of-package warning labels, the study found that these efforts have been largely ineffective in reversing obesity trends. Without stricter regulations on food marketing, particularly to children, obesity rates are likely to continue climbing.
A Guide to Restoring Your Metabolic Health by Avoiding the Four E’s
If you’re struggling with weight gain or metabolic issues, you need to look beyond the usual advice of eating less and moving more. The obesity epidemic isn’t about willpower — it’s about biology. Your cells are not producing energy efficiently, and that’s what’s driving fat storage, cravings and fatigue.
The good news? You can take back control by addressing the root causes of metabolic dysfunction. At the core of the obesity crisis are four primary cellular energy disruptors that are decimating your ability to burn energy efficiently — the Four E’s:
• Excess linoleic acid (LA), found in vegetable oils
• Estrogen and endocrine-disrupting chemicals (EDCs)
• Electromagnetic fields (EMFs)
• Endotoxins (produced by pathogenic gut bacteria)
These factors work together to poison your mitochondria — the energy powerhouses of your cells. This decimates your cellular energy production, harming your gut health in the process. As detailed in my book, “Your Guide to Cellular Health: Unlocking the Science of Longevity and Joy,” fix these, and your body will start functioning as it should. Here’s how to do it:
1. Eliminate seed oils to reduce linoleic acid intake — Seed oils are everywhere — restaurant food, processed snacks, salad dressings and even “healthy” organic products. These oils, rich in LA, damage your mitochondria. If your mitochondria aren’t working properly, your body struggles to burn fat efficiently, resulting in increased fat storage. To reduce your LA intake:
• Remove industrial seed oils from your diet. This means cutting out canola, soybean, sunflower, safflower, corn and grapeseed oils.
• Replace these with grass fed butter, ghee and tallow for better metabolic function.
• Avoid chicken and pork, as they are high in LA.
• Cook at home as much as possible — restaurants almost always use seed oils, even in expensive meals.
• Read ingredient labels. Even “healthy” foods like almond butter, hummus and organic chips often contain hidden seed oils.
2. Minimize exposure to estrogen and endocrine disruptors — Excess estrogen isn’t just a problem for women — it affects men too. Estrogen dominance is nearly as dangerous as excessive LA intake when it comes to destroying your mitochondrial function. EDCs like xenoestrogens mimic estrogen and are hidden in plastics, tap water, personal care products and even cash register receipts. To minimize your exposure:
• Ditch plastic — Store food in glass containers, don’t heat food in plastic, and use stainless steel or glass water bottles.
• Minimize exposure to synthetic estrogens — This includes those found in estrogen replacement therapy (including bioidentical estrogen) and oral contraceptives.
• Optimize progesterone levels — Natural progesterone balances estrogen and helps support metabolism and thyroid health.
3. Reduce EMF exposure to protect cellular energy — EMFs from Wi-Fi and cellphones disrupt your mitochondrial function by increasing intracellular calcium levels. This creates oxidative stress, slowing down metabolism and damaging your cells over time. To lower your exposure:
• Keep your phone on airplane mode when not in use, especially at night.
• Turn off Wi-Fi while sleeping and keep electronic devices out of your bedroom. Your body does most of its healing during sleep, and EMFs interfere with that process.
• Use wired internet instead of Wi-Fi when possible, and avoid Bluetooth devices like wireless earbuds, which continuously emit EMFs close to your brain.
• Spend time grounding in nature. Walking barefoot on natural surfaces like grass, sand or soil helps balance your body’s electrical charge and reduces oxidative stress.
4. Heal your gut to lower endotoxin exposure — Your gut microbiome plays a massive role in your metabolic health. When your gut is imbalanced, the excess of disease-causing bacteria produce endotoxins — harmful compounds that disrupt mitochondrial function. To restore gut health:
• Avoid high-fiber foods if you have gut issues. If your gut is unhealthy, fiber will feed harmful bacteria and produce endotoxin.
• Instead, focus on easy-to-digest carbs like whole fruits and white rice.
• Once your gut feels better, add veggies, whole grains and starches. These fuel your beneficial gut microbes, allowing them to produce short-chain fatty acids like butyrate that strengthen your gut barrier.
The Bottom Line
You don’t need another diet or exercise plan — you need to fix what’s disrupting your cellular energy production. When your mitochondria work properly, weight loss becomes effortless, cravings disappear and your body starts functioning the way it was designed to.
By eliminating the Four E’s, you give your body the tools it needs to restore balance and regain control over its metabolism. Start with one step at a time, and remember, this isn’t about short-term fixes. It’s about reclaiming your health for the long run.
FAQs About Obesity
Q: Why are obesity rates increasing so rapidly worldwide?
A: Obesity rates have skyrocketed due to a combination of factors, including widespread consumption of ultraprocessed foods, excessive intake of seed oils, declining physical activity and increasing exposure to environmental toxins like xenoestrogens and EMFs. People are also gaining weight earlier in life, which means they’re exposed to the health risks of obesity for a longer period.
Q: How does obesity impact health beyond just weight gain?
A: Obesity significantly increases the risk of serious metabolic diseases, including Type 2 diabetes, heart disease and obesity-linked cancers. It also contributes to systemic inflammation and hormonal imbalances, making it harder to lose weight and leading to chronic health conditions that shorten lifespan.
Q: What role do seed oils and processed foods play in the obesity crisis?
A: Industrial seed oils — such as canola, soybean and sunflower oils — are rich in linoleic acid, which damages mitochondria and disrupts your cellular energy. Combined with exposure to environmental toxins, this drives metabolic dysfunction and weight gain.
Q: How does obesity affect the economy and health care systems?
A: Obesity-related diseases are one of the biggest financial burdens on health care systems, with global costs projected to reach $4 trillion by 2035. Obesity also leads to increased rates of disability, lost productivity and higher rates of premature death, making it a major economic crisis worldwide.
Q: What can be done to restore metabolic health and prevent obesity?
A: Addressing the root causes of obesity is key. Eliminating seed oils, reducing exposure to synthetic estrogens and EMFs and healing gut health to lower endotoxin exposure all help restore proper mitochondrial function and metabolic balance. These changes allow your body to efficiently burn fat, regulate hormones and maintain a healthy weight long-term.
