Hormonal
Sleep deprivation associated with shift work leads to hormonal changes (reduced leptin, increased ghrelin) that increase appetite and obesity risk.
Ensure you get adequate sleep. If you are sleep-deprived, be aware that your body may signal higher hunger due to hormonal changes. Plan healthy snacks and meals to counteract this biological drive.
GoodSupportsHIGH confidence
Sleep deprivation is known to decrease the concentration of leptin (an anorexigenic hormone) and increase levels of ghrelin (an orexigenic neuropeptide).

- 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
