Answer:

Obesity primarily stems from diet, lack of exercise, or underlying conditions like metabolic disorders, hypothyroidism, or endocrine diseases. These factors influence how food is converted into energy, increasing fat storage. This explains why some individuals gain weight despite eating less, while others struggle to lose weight or fat even with intense exercise and strict diets.

Basal metabolic rate (BMR) is the number of calories the body burns to maintain vital functions like breathing, circulation, digestion, and temperature regulation. A person with a high BMR burns more calories and loses weight more easily. Conversely, a slow BMR leads to fewer calories burned and easier weight gain.

Frequently drinking beer, socializing, and a lack of physical activity are the primary reasons for your rapid weight gain. Beer's main components are starch and alcohol. It's high in calories: a 355 ml serving contains 153 calories. Therefore, excessive beer consumption increases caloric intake, leading to a calorie surplus and fat storage. In men, excess fat tends to accumulate around the abdomen.

Not just beer, any alcoholic beverage hinders fat burning. The immune system perceives alcohol as a toxin and temporarily halts other metabolic processes, including fat burning, to prioritize alcohol processing. This fat-burning interruption can last 12-36 hours depending on individual physique and alcohol intake.

Beer contains a significant amount of phytoestrogens, which can disrupt hormonal balance in men, affecting testosterone production. This can lead to uncontrolled weight gain, particularly in the abdominal area. This excess fat not only accumulates subcutaneously but also increases visceral fat (the most dangerous type of body fat). Visceral fat can surround the kidneys, liver, and intestines, releasing hormones that disrupt their normal function. This increases the risk of type 2 diabetes, fatty liver disease, heart disease, and cancer.
