Biological Factors Influencing Weight Regain
Metabolic Rate
Basal metabolic rate (the energy expended by the body at rest to maintain organ function) varies from person to person and primarily depends on three factors: age, weight, and height. In addition to age, rapid weight loss can also contribute to a slowed metabolism. As a result, even with consistent eating habits throughout the weight loss journey, the number on the scale tends to plateau or even increase over time.
Set Point Theory
In addition to genetic predispositions that influence weight, each individual has a "set point" weight range. Similar to a thermostat maintaining a temperature within a certain range, the body can reduce its energy expenditure to return to its "comfortable" weight range.
Hormonal Changes
Weight loss has been associated with a decrease in the appetite-suppressing hormone leptin and an increase in the hunger-stimulating hormone ghrelin. These hormonal changes can promote increased food intake and contribute to long-term weight regain.
Environmental Factors Contributing to Weight Regain
Reverting to Unhealthy Eating Habits
Returning to unhealthy eating habits, negative influences from the environment, reduced physical activity, lack of motivation, discouragement, and low self-confidence are some factors that can individually explain weight regain.
Preventing Weight Regain
By creating favorable conditions for long-term weight maintenance.
· First and foremost, a slow and gradual weight loss journey, supervised by a registered nutritionist, can help prevent a significant slowdown in basal metabolic rate.
· When the number on the scale stops decreasing or starts to rise, some individuals may become discouraged and abandon the habits they developed during the weight loss process. Cultivating a positive body image, developing strategies to respond to environmental influences, and regaining confidence in one's abilities are crucial components of motivation. A nutritionist can provide guidance in achieving these goals.
· Finally, in effective weight management, the process doesn't end when the "extra" pounds are shed. The real challenge lies in maintaining the natural weight range. Therefore, even when the scale shows favorable results, self-reflection, improving the relationship with food, and addressing eating behaviors are essential. By helping create an environment conducive to maintaining weight loss, a nutritionist can support you in making sustainable and personalized changes that align with your lifestyle.
