Obesity is a complex phenomenon that evolves in phases and has many possible explanations. Obesity evolves in two phases. The dynamic phase (or phase of constitution) is characterized by an increase in weight. It results from a break in the balance between the energy provided by the food and that expended by the body, that is to say food excess and / or decrease in expenditure. The static phase, also called “maintenance phase” during which the weight remains high.
There are two stages: During the first, the fat cells are filled with fat because of surplus calorie intake, it is called hypertrophic obesity. He is followed by hyperplasic obesity. At this stage, the fat cells, after having hypertrophied, multiply.
How is fat stored under the skin?
A malfunction of brown adipose tissue, probably of genetic origin, promotes weight gain.
Brown adipose tissue is usually responsible for energy expenditure induced by food intake and the energy expenditure induced to fight against the cold.
The root cause of obesity and overweight is an energy imbalance between calories consumed and spent.
Indeed, we are witnessing:
- Greater consumption of high-calorie foods high in fats and sugars but low in vitamins, minerals and other micronutrients
- A decline in physical exercise due to the increasingly sedentary nature of many forms of work, changing modes of transportation and urbanization.
This imbalance is the consequence of various factors:
- Genetic factors: 70% of obese have, at least, a parent in the same situation. Genetic abnormalities lead to a decrease in the expenditure at rest and physical exertion, a decrease in energy expenditure after meals and a particular distribution of adipose tissue or fat mass.
- Dietary factors: an excess of caloric intake, especially from fatty and sugary foods, compared to the needs of the body, leads to obesity. In addition, eating disorders (nibbling, food compulsions for certain foods, bulimia) are also involved in weight gain.
- Psychological factors: in case of great distress or stress, there is compensation by food, especially comforting foods with high caloric content.
- A food intake disorder: molecules responsible for transmitting messages in the brain, neuromediators, are involved in the regulation of food intake. Some stimulate it, others inhibit it. They are partly involved in the occurrence of eating disorders.
- The insufficiency of daily energy expenditure: the absence of daily physical exercises and too much sedentarily (fixation in front of the screens in particular) lead to a reduction of the energetic expenses and an unfavorable imbalance compared to the food contributions.
You dream of the flat bellies of the models on the cover of a magazine or the pretty abs of your running mate. After a pregnancy, a diet where with age, the skin of the belly falls, a detail that both women and men. We would like to be comfortable in our pretty bikini or shirtless at the beach during the summer, everything is possible thanks to the Abdominoplasty surgery in India.
Also called Tummy Tuck, this is a surgical procedure that involves removing excess skin and fat that weighs down the belly. This plastic surgery deals with the relaxation of the belly skin. The intervention is not the same for all, it varies depending on the relaxation and the amount of skin and fat in addition to the belly.
