Weight Gain

Definition

Weight gain occurs when the number of calories consumed exceeds the number of calories burned, leading to an increase in body weight.

Scientific / Technical Definition

Weight gain is the increase in body mass resulting from a combination of gains in muscle, fat, or both. It occurs when the caloric intake exceeds total daily energy expenditure, which includes basal metabolic rate, physical activity, and the thermic effect of food. This energy surplus leads to the body storing excess energy in the form of adipose tissue.

Benefits

• Increased muscle mass
• Improved strength and endurance
• Better insulation and energy reserves in cold climates
• Improved overall health when starting from an underweight condition

Examples

• Consuming a diet high in calories and protein
• Participating in strength training to increase muscle mass
• Intake of calorie-dense foods like nuts, seeds, and avocados

Additional Information

• Effects: Weight gain can be beneficial for individuals who are underweight or looking to build muscle mass, but it can pose health risks such as obesity, cardiovascular disease, and insulin resistance if not managed properly.
