Keep in mind, that it is not killing the hair follicle! And that THE HAIR WILL GROW BACK better than ever because you're consuming such great quality protein!
And also keep in mind, that as we age we lose 10-15% of our hair anyways! But I know we like to keep our long full locks don't we!?!
Keep up the good work, and know that you're burning hormonal fat!  |
I'd be interested in reading the study or literature that supports that brown fat loss is the cause. I haven't been able to find that yet.

Hey Linden!
Yes, brown fat is considered GOOD fat. It is found in highest ratios in babies and in thin people.
Brown fat is only recently being learned about and studied in adults. Brown fat really has had a great deal of research done and remarkable findings reported since 2004. Even this year there has been significant scientific journal reports done.
Brown fat location is determined by our hormones estrogen and testosterone. It can contain hormones of both kinds and it is "activated" by both the adrenaline hormones and the thyroid hormones.
The main purpose of brown fat is, essential for survival, the controlling of body temperature. This reason is key to why babies have so much brown fat. It may also be key to why those who are thin have larger ratios of brown fat. Another benefit of brown fat is that it stimulates burning of fat for energy WHEN IT IS ACTIVATED. Having brown fat and having activated brown fat are two different things. Most people who are fat have brown fat but, it may not be activated. When brown fat is activated on a regular basis it has been determined to help the body maintain an ideal weight.
The body has 2 "colors" of fat. White and Brown fat are different in purpose. White fat stores energy and Brown fat releases energy. It actually has the color of "brown" because it is so dense in mitochondria. Brown fat also contains a special enzyme which allows it to release energy from food calories in a direct process.
Brown fat is also found around organs like the liver, kidneys and heart. It is now being determined that this fat is what protects those organs by maintaining an appropriate body temperature. It is found in greatest concentrations in an adults chest and neck but, in greatest concentrations in neck and back in babies.
According to some scientific studies done in 2008, brown fat is only activated when someone feels more than a little cold.
In general, research is in agreement that white fat (especially visceral aka abdominal) is the bad fat that it is important to eliminate. Brown fat is a healthy and protective form of fat that scientist are trying to learn how to increase in people to help in eliminating and controlling obesity.
In the articles and studies I have read, I have found that people do store excess hormones in fat but, I haven't found that it is in brown fat. I have seen more notes that it is white fat. Also, the fat when burned can release many hormones, estrogen and testosterone included, and can create their own hormones.
I have found no study that specifically says burning brown fat causes hair loss but, I have found that having excess hormones of androgen, testosterone and/or, estrogen can cause estrogenic or androgenic forms of alopecia to occur. This can be temporary as it is the result of a temporary change in the hormone levels.
Hair loss can also be caused simply by a rapid change in the body, trauma, surgery, illness, pregnancy, etc. These causes bring about a rapid change and are followed by a return to what was "normal before" with in about a year of the end of the process that set off the rapid loss. I have found several reports indicating this is a common symptom following gastric bypass, or rapid weight loss (especially where more than 20 pounds is lost in a month).
"April 12, 2009: baby fat, that soft, cuddly fat that we so admire in infants, does not go away entirely when we reach adulthood. Recent studies show that this fat, known in medical terms as brown fat, survives into adulthood.
Studies have shown that brown fat is different from white fat. Whereas white fat stores calories, brown fat burns them. In fact, brown fat burns a large amount of calories. According to the study's author C. Ronald Kahn, MD, “Brown fat is filled with mitochondria, which are the part of the cell that burns energy.” Dr. Kahn is the head of the section on obesity and hormone at the Joslin Diabetes Center located in Boston, Massachusetts.
Brown fat's fat burning mechanism is activated by the cold. This fat helps keep infants warm; they don't have the shivering body effect that grownups have that automatically comes into play when it is cold. Shivering helps keep adults warm.
Although adults do not need brown fat to insulate them against the cold, the cold nevertheless activates it. Studies have shown that temperatures as mild as 61 degrees fahrenheit will stimulate brown fat. “It’s been estimated that as little as 50 grams can burn up to 20 percent of the calories taken in by a lean person if it’s maximally stimulated,” says Kahn.
Thin people and those with lower glucose levels have a greater amount of brown fat than heavy people."
