Weight gain

Weight gain refers to an increase in body weight. It can occur due to an increase in body fat, muscle mass, or water retention, and can be caused by a variety of factors including: 1. **Caloric Surplus**: Consuming more calories than the body burns can lead to weight gain, as the excess energy is stored as fat. 2. **Diet**: A diet high in processed foods, sugars, and fats can contribute to weight gain.
