Summary
Growth hormone (GH) secretion is reduced in obesity. Combining GH therapy with exercise and diet may improve body composition and restore GH release in obese adults.
Area of Science:
- Endocrinology
- Metabolism
- Obesity Research
Background:
- Obesity is associated with profoundly blunted growth hormone (GH) secretion.
- Abdominal visceral fat (AVF) accumulation is a key factor repressing GH release.
- GH administration in obese adults reduces body fat, particularly AVF.
Purpose of the Study:
- To review the literature on GH secretion in obesity.
- To explore therapeutic strategies for managing obesity using GH and exercise.
- To propose a tripartite approach for obesity management.
Main Methods:
- Literature review of studies on GH secretion, obesity, and body composition.
- Analysis of the effects of GH administration and exercise on obese individuals.
- Evaluation of the synergistic effects of combined stimuli on GH release.
Main Results:
- GH secretion is significantly impaired in obese individuals.
- GH supplementation aids in reducing body fat and AVF.
- Exercise response of GH is blunted in older and obese individuals, suggesting higher intensity is needed.
- Combined exercise and GH secretagogues show synergistic GH release.
Conclusions:
- GH repletion, combined with exercise and dietary interventions, offers a potential tripartite strategy for managing obesity.
- Exercise in conjunction with a GH secretagogue may restore GH release in obese adults.
- Optimizing exercise intensity and combining stimuli are key for effective GH release in obesity management.
