Answer:

Gaining weight despite eating little or dieting is a common concern. An individual's weight depends on various factors. Some people metabolize food into energy quickly, making fat storage difficult. Others, however, metabolize food slowly, leading to greater fat accumulation. A person's metabolic rate is influenced by genetics, age, gender, and physical activity. Slow metabolism results in fewer calories burned and weight gain.

Your weight gain despite eating little likely stems from calorie intake exceeding energy expenditure. When dietary calories surpass the body's needs, the excess converts into stored fat. Sugars in food, even from fruit, if not fully utilized, transform into triglycerides and accumulate in fat cells. Consuming small amounts, yet primarily calorie-dense foods like those high in sugar, unhealthy fats, and processed items, can disrupt metabolism and promote weight gain.

A sedentary lifestyle, insufficient sleep, and chronic stress can elevate cortisol, a hormone linked to fat accumulation, particularly in the abdominal area. This promotes weight gain even with modest food intake.

To manage weight, maintain a balanced diet prioritizing green vegetables, fresh fruits, and lean protein, while limiting sugary foods and fast food. Adopting a healthy lifestyle, including at least 30 minutes of daily exercise, sufficient sleep, adequate hydration, and stress management, also helps control weight.
