Adipose tissue is a type of connective tissue; the basic building material are adipocytes, i.e. fat cells and other types of cells- extracellular matrix (vascular fraction: preadipocytes, fibroblasts, capillary endothelial cells, macrophages and stem cells).
Adipose tissue is the main energy reserve in every human body.
Fat tissue in the body:
energy source and storage;
protection- cushioning of internal organs;
thermal isolation.
Correct amount of body fat
in women it is 20-25%, in men 10-20%.
They occur in the human body
3 types of adipose tissue; these are:
white adipose tissue (WAT);
brown adipose tissue (BAT);
pink adipose tissue (forms from subcutaneous fat tissue in pregnant women and during breastfeeding).
Additionally, there are beige adipocytes, cells considered to be a transitional form between white and brown adipose tissue cells.
Fat tissue reduction is influenced by:
caloric content of the diet- consuming fewer kilocalories than the total metabolic rate (CPM), i.e. achieving an energy deficit;
diet (complete carbohydrates, healthy fats, protein rich products; limiting flour, sugar and salt);
fat cell size- the release of fatty acids from adipose tissue is easier when fat cells are large. The smaller the fat cell, the more difficult it is to burn fat;
type of fat stored in adipose tissue- saturated fatty acids are harder to burn than unsaturated fatty acids;
stress level (cortisol)- in the case of increased levels of the stress hormone, fat burning may be hindered;
insulin sensitivity- a small increase in insulin concentration inhibits fat tissue burning by up to 90% (inhibits the release of fatty acids from the interior of adipose tissue);
physical activity (strength training, interval training, cardio);
hydrating the body (at least 30ml/kg body weight);
proper amount of sleep (7-10 hours a day);
supplementation.
Stages of burning fat tissue in the body:
mobilisation;
lipolysis (release of fatty acids from the interior of adipose tissue; fat is broken down into glycerol and free fatty acids, then transported through the blood to muscle cells and other tissues, where it can be used as an energy source);
oxidation (during the reaction with oxygen, fatty acids are broken down into energy that the body will use, as well as water and carbon dioxide, and then are excreted from the body through the lungs and kidneys).
Supplements and nutrients helpful in reducing body fat:
ginger: increases thermogenesis and increases metabolic processes;
cinnamon: increases thermogenesis and regulates insulin levels in the blood;
curcumin: reduces leptin resistance and limits the growth of fat cells;
vitamin C: helps dissolve and digest fats in the body, i.e. accelerates fat burning, which results in faster metabolism;
apple cider vinegar: supports digestion and regulates blood pressure; inhibits the absorption of fats from food in the body and removes their deposits;
coffee: accelerates metabolism, supports thermogenesis;
green tea: contains ECGC- catechine, which has the ability to stimulate fat oxidation. Flavonols contained in green tea limit the activity of the enzyme that controls the process of accumulating spare fat in adipose tissue. Increases thermogenesis;
chili peppers and cayenne pepper: accelerate metabolism and fat burning, stimulate thermogenesis processes;
oolong tea: contains caffeine and catechins, which increase the metabolic rate and support fat loss;
guarana: supports thermogenesis, improves metabolism;
synephrine and octopamine (bitter orange extract): stimulates fat mobilization and increases the metabolic rate. It has thermogenic, lipolytic and catabolic effects;
l-carnitine: helps convert fat into energy and supports the process of fatty acid degradation;
cla: increases lipolysis and reduces the accumulation of fatty acids in adipose tissue.
Regulation of insulin levels in the blood, i.e. inhibiting sudden bursts of appetite.
Thermogenesis is a set of metabolic and physiological processes that occur to maintain a constant body temperature. If these processes are intensified, the body must cool down and return to a constant temperature, which causes the metabolism to run at higher speeds and burn fat tissue faster. It is the transformation of energy accumulated in the form of fat tissue into thermal energy.
Leptin resistance, i.e. insensitivity of body cells to leptin. This is an appetite regulating hormone that sends a signal to the brain that the stomach is full.
The fat burning process is complex and regulated by many factors, such as:
nutrition/ diet, hormone levels, physical activity, hydration, sleep and supplementation, as well as general body condition; therefore, the speed and effectiveness of fat reduction varies depending on the organism.
