The fat that helps you lose weight, brown or brown fat

If you think that fat is the number one public enemy, you are in serious error. Fat is necessary to fulfill various physiological functions and, in addition, we have a type of fat, brown or brown, which if activated will help us stay in our healthy weight.

Fat mass is the most variable component in body composition, whether several individuals are compared, if a person’s changes throughout life are considered or differentiated between male or female sexes.

The fat in our body has different and important functions:

  • Synthesize lipids from surpluses of HC or proteins.
  • Respond to hormonal and nervous stimuli.
  • Secrete your own hormones (leptin, TNF-Alpha, adiponectin).
  • Energy reservoir.
  • Cushion bumps.
  • They support other organs.
  • Adult stem cells (the new era of adipose tissue).

When there is an excess of fat, an increase in the number and size of adipocytes the situation becomes pathological resulting in overweight and obesity. Obesity is characterized by an excess of fat mass that affects the health and well-being of people. The risks associated with excess fat are due, in part, to the location of the fat, rather than the total amount. Today it is postulated that the causes and metabolic consequences of regional fat distribution have particular clinical importance.


Two main types of adipose tissue can be distinguished with different roles in energy metabolism:

  • White or yellow adipose tissue . White adipose tissue contains adipocytes with a single lipid drop (unilocular) and is the main type present in human adults. White adipose tissue is distributed throughout the body, located in the subcutaneous region, around the viscera (visceral adipose tissue).
  • Brown or brown adipose tissue (multilocular) . Named for the large number of mitochondria that presents that gives it that color. The location of brown adipose tissue is more diffuse and in fact its presence in adults is minimal. Brown adipose tissue is found in small fragments around the neck (nape), the armpits (paravertebral and supraclavicular area), the kidneys (periadrenal zone) and around the large vessels of the trunk. To work it needs a lot of energy, so it burns more calories.

The histological differences between white and brown adipose tissue determine different metabolic functions for each of them, with brown adipose tissue being the main one involved in heat production (thermogenesis/thermoregulation). What follows is that the burning of calories will be increased if there is a greater amount of this type of brown fat.

Brown adipose tissue, a survival mechanism?

Babies have a greater amount of brown fat or brown fat tissue than adults. This is due, in theory, to the fact that babies cannot move or have the ability to shiver to warm up, therefore a greater presence of brown adipose tissue autoregulates their body heat thanks to thermogenesis/thermoregulation.

Computed tomography and magnetic resonance.

If we take into account, in addition, the great public health problem that constitutes obesity today, we understand the growing interest that current science and medicine have in the knowledge of the anatomical, topographic and functional distribution of adipose tissue.

Recent advances in the methodology for studying the distribution of adipose tissue, mainly computerized tomography and magnetic resonance imaging, in its various modalities, provide us with the necessary tools to evaluate the true impact of fat compartmentalization on metabolic risk factors. .

The findings obtained and observed with these methods can help to design better preventive and intervention therapeutic strategies directed towards regional fat deposits and their metabolic implications.

“Brown adipose tissue can be metabolically very important in humans, and the fact that it is reduced in adults, although still present in most people who are overweight or obese, may be essential for the treatment of obesity.”

Muscle fat

The study of muscle fat, considered today as the new fatty compartment, includes fat deposits located between skeletal or extracellular muscle fibers, as well as lipids located within skeletal or intracellular muscle fibers. Its importance lies not only in its size, similar to visceral fat, but in its possible pathophysiological implications.

”The study of adipose tissue acquires special relevance when referring to the obese individual. The improvement of the methods of assessment of body composition has made it possible to measure fat in non-adipose tissue sites such as muscle or liver, constituting the so-called * ectopic fat ”.

* Ectopic fat. Before an excess of body fat it can get to infiltrate the muscle. This could lead the body to suffer resistance to the action of insulin that is the prelude to diabetes. Ectopic fat is a deposit of fat outside the usual place that triggers a series of metabolic disorders that predispose to suffer from diseases associated with metabolic syndrome: central obesity, diabetes, dyslipidemia or hypertension.

How to activate brown or brown fat? 5 tips to raise the levels.

  • Do not go hungry, eat in an orderly, healthy and in sufficient quantity.
  • Eat an apple every day. It seems that in the skin of this fruit is the mystery, there is a large amount of ursolic acid, a compound that would positively affect creating brown fat.
  • Practice physical activity. The sport helps to lower and control the weight but also increases the levels of irisin, a hormone that facilitates the conversion of white fat to brown fat.
  • Have a little cold. When it is cold the fats are mobilized, energy is burned that is transformed into heat.
  • Stimulates the production of melatonin. Melatonin regulates sleep cycles. There are studies in rats that indicate their influence on the creation of brown fat.
