Obesity causes.

Obesity causes: Numerous factors can add to weight gain and obesity. Although body weight is affected by hormonal, behavioral, genetic, and metabolic elements, the major cause is taking excess calories for a prolonged time.

Obesity cause:

Genetics 

Obese people have numerous genes that lead them to gain weight. These genes include obesity-associated genes and fat mass. This is overall in nearly half the population. Obesity is not only caused by genes. The genetic factor is activated when people consume more calories than they require for development and energy.

Absence of exercise

If a person is not physically active, the energy provided by the food ingested will not be adequately used. The additional energy will be stored as fat in the body, directing to obesity. Exercising and being physically active boosts people’s total energy usage, helping them to keep an energy balance. This makes up for the extra food intake. Physical activity decreases overall body fat, reducing the advancement of abdominal obesity.

Overeating 

Obesity occurs when a person takes too many calories than they require regularly causing energy imbalance. These additional calories are stored as body fat by the body and tip the scale toward extra weight.

Poor diet 

Obesity does not appear all of a sudden. It grows over time as a result of bad eating habits and lifestyle. These include frequent consumption of processed and fast food, eating too much food as per psychological preferences, high alcohol intake, getting tempted by restaurant foods, and consuming it quite often is a predisposing factor for obesity, taking carbonated beverages and high sugar content liquids.

Medical reasons

In some cases, underlying medical conditions may increase weight. This includes an underactive thyroid gland where your thyroid gland fails to produce enough hormones.

At the end 

Obesity is generally generated by taking more calories, specifically those in fatty and sugary foods than you burn off through physical activity. The extra energy is kept by the body as fat. Obesity is a common problem because for many people modern living involves eating extreme amounts of high-calorie food and spending a lot of time sitting down, at desks. Some underlying health conditions can sometimes add to weight gain, such as hypothyroidism, although these types of conditions do not generally cause weight problems if they are controlled with medication.
