Monogenic obesity caused by leptin deficiency can be effectively treated with recombinant leptin therapy, restoring normal appetite regulation.
This intervention is not for the general population. It applies only to a tiny fraction of individuals with confirmed monogenic leptin deficiency. Standard weight loss strategies remain the primary approach for >99% of cases.
GoodSupportsHIGH confidence
For example, obesity related to congenital leptin deficiency has been successfully treated with recombinant leptin [122]. This approach directly replaces the missing protein, restoring normal appetite regulation and energy expenditure.
Why this rating
Cited as a successful clinical model in a review; implies strong evidence for this specific subset.

- Genetic variants in the FTO gene increase obesity susceptibility, but this genetic risk can be reduced by approximately 30% through engagement in physical activity.Moderate
- Polygenic risk scores (PRS) and genetic risk scores (GRS) can identify individuals with high genetic susceptibility to obesity, allowing for targeted preventative interventions.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
