Diabetes Epidemic Grows as Global Temperatures Rise

Global Warming Linked to Diabetes Epidemic: Reduction in Brown Fat Activity Blamed in Study

Significant increases in glucose intolerance leading to a diabetes epidemic is correlated to global warming according to a new research paper. Global warming causing decreased brown adipose tissue activity is leading to increasing cases of diabetes: a metabolic disease that results from the body becoming glucose intolerant.1)

Analyzing years of worldwide data showing climate change and the number of diabetes cases, scientists have seen a strong link between the number of cases of diabetes diagnosed each time average temperatures increased by 1 degree. Based on prior studies of brown fat activation showing exposure to mild cold is a potential therapy for diabetes, researchers concluded that: “[O]ur data are consistent with the hypothesis that a decrease in BAT activity with increas- ing environmental temperature may deteriorate glucose metabolism and increase the incidence of diabetes.”

Obesity, a factor in the cause of type 2 diabetes,  also rose in relation to increases in temperature with a 0.173% increase in obesity cases with each single degree of temperature increase. Diabetes, related to the body’s increased resistance to insulin, grew by 3.1% per 10,000 people each time the climate warmed by 1 degree celsius. Data was drawn from sources covering the years 1996 through 2013.

Weight Loss Vest: Top 5 Facts

Top 5 Facts About Weight Loss Vest Research

What studies say about cooling vests and brown fat weight loss

COMMENTARY

A brown fat weight loss vest must use mild cold

A weight loss vest cooling vest using ice packs or any cooling packs cold enough to trigger shivering are not going to properly activate brown fat to increase your metabolism and burn more calories. Brown adipose tissue uses a process called “non-shivering thermogenesis.” Non-shivering thermogenesis is the body’s natural response to mild cold. Very cold temperatures cause shivering which is a short-term and entirely different reaction by the body where rapid muscle contractions generate heat. The point where your body’s response shifts from non-shivering to shivering thermogenesis varies by individual, but is around 58 degrees Fahrenheit. Cooling vests for brown fat weight loss should not use ice cold cooling packs of thirty degrees Fahrenheit. Ice cold cooling vests and packs also create a danger of skin damage and burns from freezing. Activation of brown fat using non-shivering thermogenesis is best with special phase change material (PCM) cooling packs that can be designed to have a melting point at or around 60 degrees Fahrenheit.

A weight loss vest should cover more body surface area

Using a cooling vest for brown adipose tissue stimulation is simply a more practical solution for what you can accomplish either by being outside in mild cold temperatures or being in a mild cold room kept at or around 60 degrees Fahrenheit. Naturally the more surface area that a cooling vest covers on the body the more closely it simulates being in a cold environment. Check the size of the cooling packs that are held by any weight loss cooling vest product. Calculate the total area the cooling packs will cover to compare how effective the cooling vest may be for brown fat activation.

 Brown fat cooling packs should be designed to make full body contact

How does a cooling vest work? Cooling packs against your body act like a heat sink. There is a thermal exchange between your body and the cooling pack. While the cooling pack is colder than your body it draws heat away from your body and cools your body. So the more direct body contact made by your cooling pack, the better the performance. Ideally, flexible cooling packs with a flat surface are used that conform to the body and are held in place by a well designed vest using compression to hold the packs firmly to the body.

A longer lasting weight loss vest is better

Studies of brown fat cooling have all used mild cold exposure but for varying lengths of time and temperature. Cooling vests that have been used for scientific research to date have been chilled water circulation vests that require connection by tubes to a chiller. Time periods for the water circulation vests have been no more than a couple of hours. So the longer a cooling pack stays cold in a cooling vest for brown fat, the longer your cold exposure and logically the effectiveness. A cooling vest designed to allow easy removal of warm packs and replacement with cold spares can allow extended mild cold exposure.

A weight loss vest for brown fat should be designed for comfort and exercise

Of all considerations, comfort and freedom of movement for exercise and long wear time is key to gaining the benefits of brown fat cooling. Encouraging regular use and convenience is essential. While no studies have explored the combination of exercise and cooling to date, having an athletic cooling vest design to allow exercise in the cold should provide the most effective health benefit. The key is to hold the cooling packs tight to your body and keeping them from bouncing and moving during exercise.

While these are the five key factors in purchasing a cooling product for brown fat health benefits, keep in mind others are important such as: style, fit, quality, warranty, and value for your money.  Do your own research about what makes a real product that is a true cool fat burner and study the truth about freezing your fat off.

Brown Fat Diabetes Cooling Research: Major Positive Glucose Uptake Boost

Brown Fat Diabetes Cooling Study of Cold Acclimation Shows Profound Increase in Insulin Sensitivity in Only 10 Days

A recent study of brown fat diabetes evaluating the promise of cooling as a therapy for people with type 2 diabetes published on nature.com added to mounting evidence of major benefits. People with type 2 diabetes participating in the study of brown fat cooling showed better improvement in their insulin sensitivity than seen in the currently most recommended therapy of long term exercise for diabetes. “Insulin sensitivity was markedly increased after cold acclimation as indicated by on average a 43% increase in the glucose infusion rate….”

After just 10 days of cold acclimation people in the study with type 2 diabetes showed very significant positive impact on both whole-body and skeletal muscle sensitivity to insulin. As a result glucose uptake is markedly improved leading the researchers to conclude that brown fat cooling is a valid new way to improve the metabolic health of people with diabetes.

The method of cold acclimation to study the area of brown fat diabetes cooling therapy was remarkably simple and short. Eight overweight males were included in the study which originally was intended to include eleven to obtain valid results. During the study of the initial eight subjects the results on insulin sensitivity from cold acclimation of brown adipose tissue (brown fat) were so significant that the study was shortened with the approval of an external research monitoring board. During the ten day cold acclimation test, the study subjects were in a room kept at 14-15 degrees centigrade with exposure times increased starting with 2 hours on day 1, 4 hours on day 2, and 6 hours on days 3-10. Patients in the study used their normal medications for type 2 diabetes, ate standardized meals at the same time and were told not to exercise.

Exciting opportunities for brown fat diabetes cooling therapies are opened up by this key study, with a cooling vest for brown fat weight loss and diabetes treatment being one that is convenient. The combination of both brown fat cooling and exercise for diabetes treatment is another exciting concept: one that Dr. George King, head of research at Joslin Diabetes Center is already exploring at the Harvard Medical School institution’s headquarters where a “Joslin Coolout” workout in a cool room has started.

Benefits of Cold: Brown Fat Weight Loss

Health Benefits of Being Cold: The ATLANTIC Jan/Feb 2015 Issue

The Atlantic’s “FAT Nation” Cover

Many new research studies are examining the benefits of stimulating brown fat, the common name for brown adipose tissue, using the natural method of cold exposure. Ice vest or cooling vest products have started to appear on the market that are promising brown fat weight loss. The author tried out an ice vest that holds cooling packs and found that brown fat weight loss using a cooling vest “…carries some unlikely promise.”

A fascinating example of how mild cold exposure combined with exercise requires a massive calorie intake is the often cited example of Olympic gold medalist, swimmer Michael Phelps. In his training leading up to his record medal run, Phelps reported that he was eating 12,000 calories a day. This is many times the average daily need and even thousands more than other elite athletes training for other sports. A former NASA scientist who has studied the effects of cold on the body concluded that Phelps being exposed for hours-on-end in cold water during training was burning extra calories through brown fat activation. That same scientist started a routine of cold showers and long walks in the cold without a shirt losing 26.7 pounds in six weeks. It is a simple concept that cold exposure causes the bodies’ need to turn on brown adipose tissue and even convert white fat into beige fat to maintain core temperature leading to brown fat weight loss.

Could obesity be caused less by a lack of exercise and more by a combination of overeating and chronic lack of cold exposure in our controlled temperature indoor environments? Some experts have proposed that this is true and caused by what they call a “metabolic winter.” Human evolution for millions of years was subject to the forces of food scarcity and cold. Modern lifestyles with central heating and air conditioning are very new, a matter of seconds, on an evolutionary timeline. Not only are we as humans experiencing the effects of this change, but you can see the same problem with the pets we keep indoors.

Thankfully, it is mild cold that actually triggers the non-shivering thermogenesis response by the body that increases the volume and activity of brown fat and even converts the bodies’ bad white fat into calorie consuming beige fat. That will make it possible for a cooling vest that is a comfortable temperature instead of ice cold effective and widely used for brown fat weight loss.

Brown Fat Activated by Cold

Today an exciting new study of the effect of room temperatures on brown fat cold exposure was  presented in Chicago at a meeting of the International Society of Endocrinology.

“Our research points to a simple and practical brown fat activating and growing strategy in humans through temperature exposure modulation. We show that long-term minimal manipulation of overnight ambient temperature — well within the range found in climate-controlled buildings — was able to modulate brown fat activity in humans. Mild cold exposure stimulated brown fat activity while mild warm exposure suppressed it. Brown fat increase was accompanied by improvement in insulin sensitivity and energy burning rate after food,” said Paul Lee, MD, PhD, former research fellow at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) of the National Institutes of Health (NIH).

Brown fat cold exposure with even small changes in room temperatures over the long term will have a beneficial health affect. Temperature changes directly effect the amount of brown fat and the activity of brown fat, which in turn has an important benefit on energy expenditure and metabolism in people. The study concluded that brown fat could be harnessed by simple ambient temperature adjustments making cooling an effective tool to combat obesity, diabetes and related disorders.

The flaw with this and other papers about brown fat cold exposure is that they ignore the practical limitations of people adjusting their thermostats down to sixty degrees. In northern climates during the cold months, this may be possible. But turning your air conditioning down in a home or business to the sixties is unaffordable and not very “green.” The solution may be in portable cooling. Brown fat activation with a cooling vest for weight loss and treatment of diabetes and other metabolic diseases will be a much more practical method, and has already been shown to work.
