Why We Gain Weight

Simply, since the the energy we take with food is much more than the energy we consume, and the excess energy is stored as fat in the body. 

Everybosy has a certain basal metabolic rate. That is, the cells in the human body spend a certain amount of energy so that they can sustain their normal function. We need this energy to allow our heart beat, breathe and briefly survive. This energy is about 25-35 kcal/kg. For example, a person weighing 70 kg consumes about 2000 calories to perform normal functions. Apart from that, we need extra energy for our normal physical activities. We supply this energy requirement from foods. This equation needs to be in balance. If the amount of energy we get from the foods increases and the energy we consume with exercise decreases, the body will store the excess energy as fat and begin to gain weight. Another important issue is the genetic background of obesity. Even if the progress in genetic technology continues rapidly, a specific gene for obesity has not yet been found. Scientific data shows that it may be a genetic basis. Children who are obese are 30% likely to be obese, while children who are both obese are 50-70%. While children whose father or mother are obese are 30% likely to be obese, this rate is 50-70% in children whose both mother and father are obese. In addition, some endocrinological (hormonal) and psychiatric (eating disorders) diseases can be the cause of obesity. Endocrinologic (disorders of the adrenal glands or thyroid glands) and psychiatric causes should be investigated in patients who seel medical advice for obesity. The data presented at the SAGES meeting in the United States in 2013 revealed another interesting cause of obesity. Unfortunately, obesity has been shown to increase in countries where smoking cessation campaigns are being made.

The obesity frequency is increasing all over the world. The numbers predicted by the World Health Organization are alarming. Obesity, which is below 10% in the 1960s, has reached 30% in 2000s, and it is expected that in 2030, half of the world's population will become obese if it increases with such an acceleration.
