The United States is home to more obese people than any other country in the world. According to the Centers for Disease Control, the vast majority of American adults are either overweight (32.5%) or obese (39.8%) .
Fewer than just 3 out of 10 Americans could be considered healthy or underweight.
If obesity were an infectious disease, it would be a pandemic worse than flu, worse than AIDS, worse than malaria, worse than pneumonia. In fact, the new medical term for a constellation of risk factors related to obesity is metabolic disease, and it results in a plethora of deadly consequences such as:
high blood pressure
Type 2 diabetes
In addition to the loss of health and quality of life, the financial costs are staggering. Obesity-related healthcare expenditures in the United States exceeded $340B in 2013, and have continued to grow since.
Perhaps it is no surprise that the US weight loss industry is growing fast, too. Americans spent over $72B trying to slim down in 2018 -- and yet they're still getting fatter. In addition to extreme cases, some people undergo gastric bypass surgery to reroute food around the stomach, interrupting digestion, curbing appetite, and forcing caloric deficit in an effort to reduce fat.
Morozko thinks there is a better, simpler way--and the key is understanding "baby fat."
Human babies are born about 15% fat (by body mass) -- fatter than any other mammalian species. Moreover, they are endowed at birth with what is called brown adipose tissues (BAT), or brown fat, that plays a special role in keeping the human infant warm. The brown fat cells are packed with additional mitochondria organelles for burning lipids stored by white fat cells in a process called thermogenesis.
As human children grow, they typically lose brown fat cells, which is a process we all understand as "growing out of it". Some famous celebrities were fat children who grew up to be thin, fit adults. For example, Jerry O'Connell played the fat kid in the 1986 movie Stand by Me when he was 11 years old. Ten years later, he was almost unrecognizable as the athletic college quarterback in Jerry Maguire.
Morozko Forge CEO Thomas P Seager, as a child in the 1970's. Seager was a 9lb baby, who became a fat child, and obese Daddy, until he dropped almost 50 lbs.
Nevertheless, O'Connell's experience is exceptional.
Most people lose brown fat, only to gain white fat. In fact, brown fat is so rare in adult Americans that until new techniques for its detection were developed 10 years ago, medical scientists thought adults didn't have any brown fat at all.
Then, in 2009 researchers discovered that small reserves of brown fat at the back of neck exist in all of us. Turns out the adult human body both keeps a small amount of brown fat from infancy, and retains the capacity to recruit more.
Higher levels of brown fat are associated with decreased incidence of metabolic disease, lower BMI, increased bone health, and possibly even longer life spans, so it's no wonder medicine has taken an interest. It seems possible that the human body itself may be capable of doing what modern medicine has thus far been unable to -- find a cure for the obesity epidemic -- because unlike white fat, which stores energy, the purpose of brown fat is to burn it.
And the best way to retain or recruit brown fat is by deliberate cold exposure.
Being only ten years since the re-discovery of brown fat in adults, the science is still in its infancy and there is a lot that remains to be studied. For example, brown fat can also be activated by catecholamines, which are stress hormones released during the sympathetic nervous system’s “fight or flight” response. This is particularly interesting to ice bathers, given that both stimuli -- cold exposure and acute stress response -- are present in the ice bathing experience.
This could mean that ice bathing could be doubly effective at activating and generating brown fat and, thus, doubly effective as a therapy for fat loss. Despite the billions of dollars invested in the fight against metabolic diseases, modern medicine isn't any closer to finding a magic pill or surgical treatment that will permit constant thermal comfort and modern diets and lifestyle without deleterious metabolic effects. Ong, et al (2018) suggests that science needs a new, uniform cold exposure protocol to better understand the effects of cold exposure and how brown fat can be harnessed to develop treatment protocols for obesity.
Morozko isn't waiting for the pharmaceutical industry to encapsulate cold exposure in a pill. Our experiences of weight loss, health restoration, and metabolic regulation have been so profound that we will continue to experiment with our own protocols for cold exposure, diet, fasting, and metabolic regulation that have proven to give positive results.
