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 Cooling Vest to Treat Childhood Obesity: Door Opens to Research

Research Opens Door to Study of Brown Fat Cooling Vest in Children

Childhood Obesity Crisis

As you can see in the above graph, Childhood obesity is perhaps the greatest health crisis facing the United States and the world. Recently published research which included the use of a brown fat cooling vest to activate brown adipose tissue, showed that less expensive, non-invasive readings of skin and core temperature may be used to study the effect mild cold exposure has on brown fat activity which could lead to the study of brown fat cooling for childhood obesity.1)1 To date measurement has involved radiation exposure using an MRI or PET scan, which would rule out studies involving children even though safe mild cold exposure using a cooling vest is a potentially safe, non-pharmaceutical treatment for childhood obesity and related metabolic disorders such as diabetes.

Brown adipose tissue (brown fat or BAT) has always played an important role in maintaining a steady state body temperature in mammals and has been newly discovered to have a role in people. Because BAT studies have shown the potential path towards new treatments for obesity and related metabolic disease like diabetes, new ways to research human BAT activity that are less expensive and invasive can lead to breakthroughs for our health. The most exciting opportunity is to open the door to studying the impact of mild cold exposure using a brown fat cooling vest for children that is safe, effective, and simple to use at an affordable cost.

Study Method Included Brown Fat Cooling Vest for Mild Cold

A trial was conducted that included 18 men who were divided into two groups. Using known PET and MRI methods of measurement, but adding measurements of skin temperature and body core temperature, the groups were 10 who already had pronounced BAT activity and 8 who had little to no BAT activity. Exposing these volunteers to mild cold using a combination of room temperature controls, liquid cooling vests and blankets, allowed the scientist to determine if skin and core temperature measurements could be used instead of PET and MRI methods.

Results of the study provided further proof that mild cold exposure triggers a response in brown fat in humans to maintain core body temperature just like any mammal. There was a strong correlation between the volume of brown fat in person and response to cold. Most significant was the finding that “…the significant correlation between the cold induced change in core and supraclavicular [skin temperature at the collar bone] temperature suggest those two measures as a potential [measure] of BAT activity.”

These safer, non-invasive, non-radiation, easier to perform and less expensive measurements of brown fat can open the door to the study of the effectiveness of treatments for obesity include the safe use of mild cooling with a brown fat cooling vest for children. This would provide an option in the near term to help fight the childhood obesity epidemic.

Brown Fat Cooling and Exercise

Brown Fat Cooling During Your Workout: A Hot Fitness Trend?

Combining exercise with brown fat cooling may accelerate metabolism

brown fat cooling

Cool workouts could be the next hot fitness trend

A leading researcher who authored a book on diet and lifestyle changes to manage diabetes has encouraged using a cold exercise room for brown fat cooling. Dr. George King, the head of research at the Joslin Diabetes Center at Harvard Medical School in Boston, has started a “Joslin Coolout” exercise program that has people working out in a room chilled to t60 degree range. The idea is to create brown fat cooling during exercise to combine the metabolic benefits of brown fat activation by cooling with the benefits of exercise. Dr. King is the author of “The Diabetes Reset” which has a 12 week plan incorporating 8 changes to your diet and life to prevent diabetes including brown fat cooling in a cool room or wearing a cooling vest for weight loss.

The concept of a cool workout to improve weight loss has already spread to a boutique fitness studio in Boston near the Joslin Center. A fitness class is offered in the basement studio with the thermostat set at 62 degrees, and is already popular with people who will try anything to burn some additional calories.  Dr. King is quoted as supporting the double benefit of exercise and brown fat cooling: “Not only do use up the calories from the workout itself, but you can also activate the brown fat, which burns up calories and generates heat.”  “Cool workouts could be the next hot fitness trend,” Weintraub, USA Today 8/2/15.

it is not clear to what extent the combination of cold exercise and brown fat cooling can boost metabolism, but future studies can research the benefits of brown fat cooling vests, exercising in a cool room, and turning down your thermostat at home. But it is clear that a leading expert believes that mild cold and its role in stimulating brown adipose tissue will lead to promising health benefits in controlling obesity and diabetes.
