Insufficient sleep and circadian misalignment act as novel, modifiable risk factors for obesity by altering hunger hormones (ghrelin, 2-AG), increasing hedonic food appeal, and reducing energy expenditure.
Prioritize 7-9 hours of sleep as a primary weight management strategy, not just a luxury. If you are struggling with weight loss, evaluate your sleep duration and consistency first, as sleep loss biologically increases hunger hormones and cravings for high-calorie foods.
Insufficient sleep and circadian misalignment are thus new modifiable risk factors for obesity.
Why this rating
The paper cites multiple meta-analyses, prospective cohort studies, and controlled experimental trials, though it is a review paper summarizing others' work.

More from this paper
- Time-Restricted Feeding (TRF) restricts food intake to a specific window (e.g., 12 hours) and serves as an effective countermeasure to prevent obesity induced by circadian misalignment (shift work/jet lag) and high-fat diets.Good
- Sleep restriction increases the appeal of sweet/dessert foods and activates the endocannabinoid system (2-AG), driving hedonic food intake and obesity risk.Good

- 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
