Fat deposits are small excess pockets of fat that form adipose tissue. These can be located in very specific parts of the body or spread over broader areas, such as the thighs or arms.
Adipose tissue is made up of adipocytes, which are eight times larger than regular cells and responsible for fat synthesis and storage to provide the body with energy. The number of adipocytes is fixed after adolescence, and their size adapts to the body’s needs. When fat intake is lower than energy requirements, they shrink. Conversely, when fat intake exceeds energy needs, they expand, sometimes up to ten times their original size, leading to excess fat deposits.
These fat deposits can settle in several areas of the body, such as :
- Thighs
- Buttocks
- Abdomen
- Saddlebags
- Inner knees
- Neck
- Chin
Several factors contribute to fat deposits. Weight gain, associated with a sedentary lifestyle and an overly rich diet, is the primary cause. However, hereditary predispositions can favor fat storage in some individuals. Hormonal imbalances and fluctuations, such as during puberty, pregnancy, and menopause, also play a significant role.
