Obesity involves molecular mechanisms, including metabolic memory and epigenetic modifications, that actively hinder weight loss and promote weight regain.
If you are struggling to lose weight despite diet and exercise, recognize that your body has biological defenses (like metabolic memory and hormonal shifts) that actively work to restore previous weight. This is not a failure of willpower but a known physiological response. Addressing these barriers may require a multidisciplinary approach, potentially including medical interventions, rather than just stricter dieting.
Evidence has shifted our understanding of obesity from a purely behavioral issue to a more complex, multifactorial disease. Several molecular mechanisms are known that actively work against weight loss and promote weight regain.

- Epigenetic changes, such as DNA methylation and histone modifications, can persist after weight loss and contribute to weight regain.Moderate
- Adipose tissue dysfunction, characterized by chronic low-grade inflammation and insulin resistance, creates a self-perpetuating cycle that promotes obesity.Moderate
- Current interventions, including calorie restriction, physical activity, and pharmacological treatment, show promise in combating obesity, but long-term efficacy and safety need further establishment.Moderate

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
