The display window of a neighborhood bakery, filled with thick layers of cream and colorful pastries, is often irresistibly tempting. For some people, however, it is far more than an appealing sight—it is the battleground of an exhausting internal struggle. Inside their minds, a persistent voice constantly urges them to eat, whispering feelings of hunger that do not truly exist. This psychological phenomenon is known as food noise, a relentless cycle of food cravings that has become one of the greatest challenges in the global obesity crisis.
For decades, society has been quick to blame excess body fat on personal failure. People living with obesity have often been labeled as lazy, gluttonous, or lacking the willpower to maintain a healthy diet. Modern science, however, is beginning to dismantle these harsh stereotypes. In the in-depth video essay “The Ozempic Truth No One Wants To Say” on the Viva Longevity! YouTube channel, narrator Chris explains that obesity is, in fact, a complex chronic disease. Its primary drivers are not weak self-control or a lack of discipline, but biological disruptions rooted in modern culture and the surrounding food environment.
The roots of the problem can be understood through the epidemiological concept known as the web of causation. This framework illustrates how modern environments have become saturated with highly addictive foods that interfere with the brain’s natural satiety signals. The food industry has deliberately engineered ultra-processed products to be exceptionally difficult for humans to resist.
Chris illustrates this through behavioral experiments conducted by Professor Kenny. When laboratory rats were fed only natural foods that aligned with their evolutionary diet, they ate only when hungry and stopped naturally once satisfied, maintaining healthy body weights.
Everything changed when Professor Kenny introduced a slice of cheesecake into their enclosure. The rats immediately became compulsive eaters, consuming the cheesecake uncontrollably until they developed obesity within just a few days. The most striking finding came after the cheesecake was removed and healthy food was reintroduced. Rather than returning to their natural diet, the rats refused to eat and nearly starved to death. They had become addicted to artificially engineered flavors. Chris argues that modern humans now live in a similarly aggressive food environment, where ultra-processed foods continuously bombard the brain with irresistible temptations.
This unhealthy environment is further compounded by the erosion of healthy food traditions. Yet the strongest metabolic protection actually begins in early childhood. Nutrition expert Dr. Federica Amati explains that children experience a “golden window” during which their gut microbiome is established. That microbiome later influences taste preferences and food cravings throughout adulthood. Countries with strong traditional food cultures and well-established healthy school lunch programs have consistently demonstrated significantly lower obesity rates.
The Cultural Factor
Culture also plays a decisive role. For example, Asian Americans live in the same fast-food environment as the rest of the United States population. Nevertheless, their obesity rate remains around 18%, substantially lower than the U.S. national average of 42%. Countries such as Japan, France, and Spain likewise maintain relatively low obesity rates because their populations continue to embrace traditional eating habits centered on whole foods consumed slowly and communally.
When modern environments have already disrupted human biology, GLP-1 medications such as Ozempic and Wegovy have emerged as powerful treatment options. These drugs function almost like an advanced spam filter for the brain, dramatically reducing the constant stream of food noise experienced by many patients.
This has created a curious cultural paradox in several developed countries. Many people remain deeply skeptical about the minor side effects of vaccines while enthusiastically embracing injectable weight-loss medications.
Yet despite their remarkable effectiveness, these drugs also carry genuine health risks. Medical data indicate approximately a 2% risk of gallbladder disease among users. There is also a rare risk of Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION), a condition that may cause permanent blindness, affecting roughly 2 out of every 10,000 users. The condition is believed to result from significant drops in nighttime blood pressure that reduce blood flow to the optic nerve. Other potential complications include pancreatitis, which carries a mortality rate of up to 10%, as well as substantial muscle loss if patients fail to combine treatment with regular resistance training.
One of the most persistent claims surrounding these medications is that patients must continue taking them for life to prevent regaining lost weight. Fortunately, large-scale medical data from Epic Research, involving approximately 140,000 patients, challenge that assumption.
After tracking patients for two years following discontinuation of Semaglutide, researchers found that only 23% regained all of the weight they had lost. Meanwhile, 15% successfully maintained their weight, 16% continued losing weight, and 26% actually achieved even greater weight loss after stopping the medication.
These findings suggest that dependence on injectable medications is not inevitable. The key is to use these drugs as a temporary bridge toward rebuilding a healthier emotional relationship with food—not as a license to continue unhealthy eating habits.
A practical example comes from Dr. Bean, a family physician who reduced his weight from 310 pounds (approximately 140 kilograms) to 160 pounds (approximately 76 kilograms) and has successfully maintained that weight for 24 years without medication. His strategy centered on radically transforming his home environment by eliminating ultra-processed snacks, walking every day, and committing to a diet based on whole, natural foods.***
